Is Carbon Capture and Storage a Viable Option?

Sun ,17/10/2021

The countries of the world have reached a consensus that we need to reduce our carbon emissions. One proposal to do that is to switch to a hydrogen economy. The problem is that currently about 95% of the hydrogen we use is made using fossil fuels, which is an energy-intensive process that produces more CO2. The fossil fuel companies plan to get around that is to capture the carbon produced and store it (CCS). The questions that must be answered are how to capture the carbon, where to store it, and how much it will cost.

It is possible to capture the CO2 and there are now several plants currently doing it. Much of the captured carbon is currently used to produce more fossil fuels, so there is little gain in doing it. The chart below will give you an idea of the magnitude of the problem. Currently, we are adding 35 billion tons of carbon dioxide to the atmosphere each year. The amount of carbon currently captured is 0.006% of that, an amount so small that it could not even be seen on the chart.


If carbon capture could be scaled up to capture most of the CO2 we are emitting, then where would we store it? The most obvious solution is to store it where it came from. The carbon from coal is mostly from strip mines and open mines, and it cannot be stored there. For petroleum and methane, storing it back underground is a possibility. However, burning them combines them with oxygen – and increases the mass and volume by a factor of two or three. It would be impossible to store more than a fraction of the CO2 back underground.


Assuming we could capture the carbon and find a place to store it, what would be the cost? This would involve acquiring the land, building the thousands of CCS plants required, and providing the energy necessary for the process. That cost has been estimated to be about $5 trillion a year, at current prices, for the rest of this century. There are certainly much less expensive options available.


So there you have it, the amount of CO2 we are putting into the atmosphere is far too great to capture, there is no adequate place to store captured CO2, and the cost would be astronomical. However, the fossil fuel companies are willing to try if we subsidize their costs, fund their research, and wait 80 years. It will be painfully obvious, long before then, that CCS is unworkable. The best plan is obviously to stop putting more carbon dioxide into the atmosphere, a solution the fossil fuel companies are unwilling to accept.


The Mythical Magic Hydrogen Economy

Tue ,02/03/2021

There’s a little bit of truth to every myth, and the hydrogen economy is no different. Hydrogen fuel cells would be wonderful for the environment. They combine hydrogen with oxygen from the atmosphere to produce electricity, and they emit pure water. The hydrogen can be made by electrolysis of water, and the energy for the electrolysis can be provided by renewable energy such as solar and wind. Though hydrogen must be stored at high pressures or low temperatures, it can be transported and used to replace fossil fuels in most of their applications. Then why are the fossil fuel companies so eager to transition to a hydrogen economy? They now are applying for grants from stimulus money for research on hydrogen power. There must be more to the story and that is where magic comes in.

It would take a tremendous amount of magic to make hydrogen a viable source of energy within 30 years. Currently, 95% of commercial hydrogen is made from fossil fuels, primarily methane. Producing hydrogen from methane is energy intensive. It requires that methane be reacted with steam-heated to about 1100°C. That reaction produces hydrogen and carbon monoxide – which is then treated with additional steam at 380°C to convert the carbon monoxide to carbon dioxide. Not only is carbon dioxide produced as a byproduct, but it takes a tremendous amount of fossil fuel to heat the steam hot enough to carry out the reaction. Hydrogen produced in this way is called Brown hydrogen, because of all the fossil fuels used. You’re probably beginning to see why fossil fuel companies are so eager to transition to a hydrogen economy.

But wait. All we would need to do is capture the carbon dioxide produced in making Brown hydrogen and store it underground. Hydrogen could then be produced without adding more CO2 to the atmosphere, so it is called Blue hydrogen. Fossil fuel companies are now pursuing grants and subsidies to develop Carbon Capture and Storage Systems (CSS) to do just that. But there are a few problems. Fossil fuel companies knew as far back as 1979 (see memo below) that adding more CO2 to the atmosphere would cause global warming and damage the environment. A CSS system requires little new technology, so why did they not develop CSS then – and global warming would never have become a problem. Fossil fuel companies did not do it because it would have made their products more expensive, and demand would have gone down. And they are even less serious about developing CSS systems now. With prices dropping on renewable technologies and energy storage systems, CSS would make carbon or hydrogen fuels so expensive that it would accelerate the transmission to renewable energy and battery storage.

Though there are currently large supplies of methane available from fracking operations, using fracked methane to produce hydrogen just isn’t a good idea. The main problems associated with fracking are methane leaks and earthquakes (caused by the disposal of fracking fluids). It has been estimated that about 20% of the methane produced at the wellhead is lost through transmission losses and leaks. Because so much methane is lost during production, France has recently prohibited American fracked methane from being sold there. Though the amount of methane in the atmosphere is small, methane is 72 times more potent as a greenhouse gas than carbon dioxide. As the graph below shows, the methane concentration in the atmosphere has grown exponentially – and it now accounts for about 1/4 as much global warming as carbon dioxide.

That brings us to hydrogen produced by electrolysis, called Green hydrogen. To create the infrastructure to produce enough Green hydrogen to transition to a hydrogen economy would take more than 30 years. To get there, we would have to start now. That would require Black and Brown hydrogen to be used while we develop a CSS system, and then Blue hydrogen could be used until we have a fully operational Green hydrogen infrastructure. We would be dependent on fossil fuels for at least 30 more years, and the concentration of carbon dioxide in the atmosphere would certainly go up. The best carbon capture systems are trees, oceans, and soils (through regenerative agriculture). Currently, those systems have not been able to keep up. Deforestation, commercial farming, and the acidification of the oceans are exhausting those systems’ abilities to capture CO2. The environment of the Earth cannot absorb much more carbon dioxide, and we certainly can’t wait 30 years on the chance that a commercial scale CSS system will be developed.

Hydrogen is very useful for things such as welding, food processing, ammonia production, and rocket fuel – but it will never be useful to power our economy. That is because a hydrogen economy would be terribly energy inefficient. If you were to use electricity from wind to produce hydrogen, transport the hydrogen to where it is needed, and use hydrogen fuel cells to power your car, about two-thirds of the energy would be lost in the process. The electrical energy that would take you 300 miles in a battery-powered car, would only take you 100 miles in a hydrogen-powered car. There is also no infrastructure in place to conveniently transport large volumes of hydrogen. Natural gas pipelines could not be used, as hydrogen reacts with metals and makes them brittle. I contrast, transmission lines for electricity are already in place and, if upgraded to handle the larger load, they could deliver power directly to your home and your car – and do it three times more efficiently.

Finally, hydrogen is explosive. If you have ever seen a hydrogen filled balloon exploded, you are probably aware of the tremendous power of a hydrogen explosion. Hydrogen explosions are rare, but are bound to happen if hydrogen were in wide use. A hydrogen explosion occurred in an AT&T Uninterruptible Power Source battery room in 2020. The explosion blew a 400 square foot hole in the roof and collapsed walls and ceilings throughout a large portion of the 50,000 square foot building. Fortunately, the computer/data center was vacant at the time and there were no injuries.

All things considered, unless you own a fossil fuel company or believe in magic, trying to convert to a hydrogen economy is a really bad idea.

Global Warming: The Rise of Methane

Mon ,15/02/2021

New

Greenhouse gases play a huge role in keeping the surface of the Earth warm. Without the greenhouse effect, the temperature of the Earth would average about -18°C, and all the water on the Earth’s surface would be ice. The average temperature of the Earth’s surface is now about 15°C and rising. The graph below shows the concentration of the main greenhouse gases in the Earth’s atmosphere, and how they have changed in the last two millennia. 

Inarguably, an increase in the greenhouse gas concentrations will warm the Earth – and we are seeing that happen. The average temperature of the Earth is now 1.2°F warmer than it was in 1850. The temperature of the Earth was fairly constant over the thousand years before the industrial age, and people, plants, animals, and our agricultural practices have adapted to that temperature. What will happen as the Earth’s temperature rises? We are finding out, and the effects are alarming.

Of the greenhouse gases, water accounts for about 70% of the greenhouse effect, carbon dioxide about 20%, methane 4%, nitrous oxide 1%, and the other greenhouse gases together about 5%. Our efforts to reduce global warming have focused mostly on carbon dioxide, as its concentration has increased over 40% from our use of fossil fuels. It will take time to phase out fossil fuels and transition to the use of renewable energy. The concentration of methane has grown appreciably in the last century, from about 800 parts per billion (ppb) to over 1900 ppb and it is rising rapidly. Methane has about an eight year half-life in the atmosphere before it is converted to carbon dioxide by natural process. The methane in the atmosphere would decrease quickly if we stopped putting it there. That is important, as methane has about 72 times the global warming potential of carbon dioxide.

The main cause of the rise in methane is commercial leaks, oil production, and fracking operations. In commercial sales, it is sometimes less expensive to ignore small leaks than to fix them. But many small leaks add up and it has been estimated that about 10% of natural gas put into pipelines is lost before it reaches the end user. Some of those problems could be fixed. Methane is also produced as a byproduct of oil production. If the amount of gas is too small to be sold commercially, it is often flared, i.e., lit like a torch. That converts it into carbon dioxide, which is less damaging to the environment. 

Fracking operations now produce a tremendous amount of natural gas for commercial use, and considerable amounts of methane escape into the atmosphere from the drilling operations and pipeline leaks. It requires effort and resources to contain the methane at the wellhead and to fix storage and transmission leaks. The EPA requires that leaks be self-reported, but often they were just ignored. Just recently, it has become possible to detect methane from GHGSat satellites. Below is a map that shows eight leaks in a 25 mi.² area in Turkmenistan, as they were seen by satellite. Estimates were that those leaks accounted for about 10,000 kg of methane a day. The methane was from fracking operations, pipeline leaks, and unlit flares.

Before satellites, most methane emissions were discovered by infrared cameras. Using them, it was found that the methane emissions from the Permian basin in Texas and New Mexico were much greater than those reported. Much of that came from unlit flares, which could easily be corrected. One accident at a gas well in Ohio is now thought to be the largest methane leak ever in the United States. Three different oil and gas facilities in Algeria were found to be leaking methane amounts equivalent to the carbon dioxide produced by a medium-size coal-fired power plant. The detection of leaks has been spotty and regulation of leaks has been difficult in the past. There is considerable economic incentive for gas companies to reduce methane emissions from leaks. However, it is expensive to send out crews to detect and repair smaller leaks, and many companies have just let them go.

The EPA expects the oil and gas industry to self-report and to repair leaks, but many companies just don’t. There are plans to deploy seven more GHGSat satellites to monitor greenhouse gas emissions. With them, it will be possible to detect and enforce the regulation of many methane leaks. It has been estimated that cutting methane emissions by 40% would have the same effect as taking 60% of the world’s coal-fired power plants off-line. And, we could easily cut methane emissions by 40% within the next decade.

Global Warming and the Jet Stream

Sun ,14/02/2021

The Arctic is much warmer now than it was 30 years ago. They even had 100° days in Siberia last summer. The warming Arctic has caused changes in the jet stream, which controls the Northern Hemispheres’ weather. The Rossby waves in the jet stream,  that move from west to east across the United States, (see picture), now come down further and move slower from west to east.

This means that the jet stream can sometimes pull Arctic air down from the Arctic region, called a Polar Vortex. The slower movement of the Rossby Waves causes the extreme cold to persist for longer. It is 3° today in Kansas, the windchill is -15°, and this cold spell will persist for about a week. If it is extremely cold and snowy where you live, you can thank global warming for that.

Apparatuses of Justification

Fri ,05/02/2021

In his internationally renowned work, Capital in the Twenty-First Century,  Thomas Piketty says that extreme economic inequality can only be sustained by “apparatuses of justification.”  He states, “ The existence of such “apparatuses” can hardly be disputed; the notion that wealth rightly belongs to those who possess it, no matter the means by which they acquired it or the needs of others around the world, is certainly well within the mainstream of contemporary thought, especially in North America and Europe. Ideas such as this did not, however, permeate contemporary culture on their own. They are derived, developed, and distributed by corporations, government offices, “independent” think-tanks, etc.” Two apparatuses of justification that immediately came to mind are trickle-down theory and the lies created by the Cornwall Alliance.

The trickle-down theory claims that the best way to promote economic prosperity for everyone is to give tax breaks to large corporations and those already wealthy. The idea this promotes is that they will create jobs and provide opportunities for those less well off. It was tried on a large scale in the United States under Reagan, Bush ll, and Trump. Over the years, many poor and middle class citizens have voted for politicians advocating trickle down theory. It is a flawed theory, wealth actually flows upward and pools at the top.  Meanwhile, after 40 years, they are still waiting for their share of the wealth trickle-down. The wealthy have become wealthier, the poor poorer, and the economic inequality in the United States has grown to unacceptable levels, as shown in the graph below.

After all that time, many Americans still do not realize how they have been fooled, as the chart below shows.

The Cornwall Alliance was originally started to help the poorer countries adapt to climate change. When E. Calvin Beisner took over as its spokesman, he interpreted that to mean that the Third World countries needed to use more fossil fuels. Never mind that they do not have the infrastructure or wealth to acquire and use them. Under his leadership, the Cornwall Alliance has become funded by dark money, most of which can be traced to fossil fuel companies. Who else? Beisner created the Green Dragon Monster, which he uses to represents environmentalists who want to reduce our dependence on fossil fuels. He uses “climate alarmist” to represent the 99.5% of climate scientists who have shown that climate change is caused by man’s activity, and “climate doomsayer’ for those who agree with scientists that global warming is harming the Earth.

Beisner uses religious arguments to reach out to conservative Christians and solicit donations. There is little evidence that the money goes to the poor, being used mostly to pay himself to distribute his message. He interprets, “God giving man dominion over the earth ”, Genesis 1:26-28, to mean that God has given man the right to exploit nature as he pleases. Apparently, he has very little understanding of ecology. Pope Francis’s encyclical on ecology, Laudato Si, says that “climate change is real and mainly a result of human activity.” “The problem is urgent. Never have we so hurt and mistreated our common home as we have in the last two hundred years.” Beisner claims that Pope Francis was just wrong, probably news to most Catholics.

Beisner’s position is even at odds with his own Presbyterian faith. The Presbyterian Church is now recommending divestment from fossil fuels and it was one of the first churches to address global warming. The Presbyterian Church first noted its “serious concern over global warming at the 1990 General Assembly, when it warned that the global atmospheric warming trend (the greenhouse effect) represents one of the most serious global environmental challenges to the health, security, and stability of human life and natural ecosystems’’.

There are many other examples of apparatuses of justification. You may recognize them by their tendency to label their opponents with unflattering terms; by their opposition to scientific research; by their derision of mainstream religious leaders; and, by their distortion of the truth. Ask yourself, “Who profits from their message?”, and if it is a special interest group, recognize it for what it is. And above all else, vote for the political candidates opposed to those special interest groups.

Has Global Warming Made Hurricane Damage Worse?

Sun ,31/12/2017

Hurricanes are the most violent and destructive storms in nature. There’s a smaller, yet potentially destructive, storm raging between climate scientists and climate skeptics about the nature of hurricanes. The scientific evidence points to the fact that global warming  causes hurricanes to be more intense. Skeptics would like to convince everyone that global warming has not made any change in hurricanes, so there is no need to address global warming. Skeptics do have a point or two, but not many. Skeptics want absolute proof from the scientists, but science doesn’t work that way. The changes caused by a warming world have changed the probability of the occurrence of extreme weather events, and skeptics apparently don’t want to consider probabilities.

Skeptics say that the number of hurricanes in the Southern Atlantic is not increasing, and they’re probably right on that. Hurricanes begin as tropical storms, which occur at random depending on the weather conditions. Skeptics also say that the increasing economic damages done by hurricane is because of the increased construction along the coasts. That is partly right, but it is also right that the damage done by storm surges has increased because of increased sea level rise, which is a measurable consequence of global warming. Those who listen to the skeptics, and unwisely build in floodplains, are sure to experience more damage from storm surges.

Global warming has made the oceans much warmer, even later into the year. The water temperature must be above 82°F for a tropical storm to grow into a hurricane, and the warmer the ocean the more likely it is that the a hurricane, once formed,  will intensify. Hurricanes are much like a heat engine, they are driven by the warm air rising from the oceans much like a chimney effect. The greater the temperature difference between the ocean and the upper atmosphere, the faster the flow upward and the greater the wind speeds.

If you could slice into a hurricane, it would look something like the diagram below. It has a low pressure eye at the center, and the air drawn into it rises and circulates counterclockwise around the low pressure area, faster and faster as it nears the eye. The small red arrows show warm, moist air rising from the ocean, and forming bands of clouds around the eye. As the warm moist air produces rain, more heat is released, warming the air further and causing it to rise faster until it reaches the top of the storm. Reaching there, it has become cooler and dryer. The blue arrows show how the cool, dry air then sinks in the eye and between the bands of clouds. Remember that the bands of clouds are rotating very quickly, and the large red arrow show the rotation of the rising bands of clouds.

.                                                                                                                                                      Credit: Kelvinsong

A hurricane is much like a heat engine. It is driven by the energy from the warm oceans and the cold temperature of the atmosphere above the storm. Because of global warming, that temperature difference is greater. The upper atmosphere receives its energy from the earth below. The increasing carbon dioxide between acts as a blanket, which causes the oceans to be warmer and the upper atmosphere to be colder. As in all heat engines, the greater the temperature difference, the more power the engine has. As a hurricane passes, it leaves the oceans cooler behind it as it sucks energy from the ocean. Because of global warming, the warmth goes deeper there is a greater area of warm water,  both factors which provide more heat to the hurricane and cause it to increase in size and intensify.

The vapor pressure of water increases exponentially with temperature. In our warmer world, there is now 10 to 15% more water vapor in the rain bands moving around the hurricane. When hurricane Harvey made landfall over Houston, it could be expected that Houston would receive increased rainfall. But by chance, Harvey stalled  over Houston and continued to pull warm moist air in from the Gulf, dumping over 50 inches of rain. Sea level rise has been measured to be about 30 inches along the Gulf Coast. The extreme rainfall coupled with the sea level rise  increased the storm surge and flooded much of the lower areas of Houston. The storm’s stalling was a chance event, and the skeptics are right when they say it should not have happened, but it did. Considering the storm’s intensity, the wind damage, the sea level rise, and the extreme rainfall, climate scientists attribute about 30% of the damage in Houston to global warming.

Below is a satellite image of hurricane Irma on the right, compared in size to the smaller hurricane Andrew which struck Florida in 1992, killing 65 people, destroying 65,000 home, and doing $26 billion in damages. Andrew was the  the most destructive hurricane to hit Florida ever before, and Irma could have been much worse.  

Florida was extremely lucky that hurricane Irma, wider than the whole Peninsula, went up the western side of the Peninsula. The western side of the  Peninsula experienced very little storm surge. The winds on the leading edge of the Irma, circulating counterclockwise, blew the ocean water away from shore, leaving the ocean dry for several hundred yards out as it passed. The storm was so weakened that by the time the back of the storm made landfall, directing the water toward shore, that the storm surge was only a few feet. Had Irma gone up the east side of Florida, the storm surge at the leading edge of the hurricane could have been as much as 15 feet, completely inundating much of Miami.

There you have it. Global warming has increased the temperatures of the oceans and has increased the temperature difference between the oceans and the upper atmosphere, both factors which tend to make the hurricanes more intense. The warmer oceans put more moisture into the air, making the rainfall from the hurricanes greater, and sea level rise has increased the height of the destructive storm surges. This fall, there were five intense hurricanes which formed in the Southern Atlantic, all of them making landfall and doing extensive damage. That could just be a chance occurrence, as the skeptics claim, but it has never happened before.

Who’s Afraid of Climate Change?

Mon ,06/11/2017

What do you fear? People are moved to action by their fears. Sometimes our fears lurk at the edge of our consciousness, and then are brought into sharp focus by events. Dying oceans, polluted lakes and streams, unsafe drinking water in major cities, catastrophic hurricanes, severe drought and wildfires, and an increase in the severity of weather events, have brought environmental problems into the things Americans fear.

The annual Chapman University Survey of American Fears in 2017 provides an in-depth examination into the fears of average Americans. The survey looked at 80 fears and ranked them according to the survey responses The chart below lists America’s top 10 fears for 2017. For the first time ever, not one, but four of the top 10 fears are related to the deterioration of the environment. Pollution of natural waters, unsafe drinking water, global warming, and air pollution are now among Americans worst 10 fears.

It is not only natural disasters that occurred in 2017, but also political events . Americans had considered that the Environmental Protection Agency would protect our natural waters from pollution. However, Scott Pruitt, the current Environmental Protection Agency director, decided not to enforce major pollution laws, and fired the EPA’s entire Science Advisory Board. No advice, no research, no problem. People are beginning to realize that what you don’t know can hurt you.

The publicity surrounding the failure of the state and local government of Flint Michigan to protect the city’s residents from lead poisoning, and the subsequent discovery of lead and other toxins in our city water supplies, have made people fear that their water is not safe to drink. Almost everyone lives downstream from someone, and pollutants that find their way into our water supplies are bound to find their way into us.

Many Americans perceived the results of climate change remote and far into the future. The attribution of worsening disasters to climate change, and the US withdrawal from the Paris Climate Accord have brought carbon emissions and air pollution into sharper focus. Pictures of severe smog in China and the data from the American Heart and the American Lung Associations about the number of deaths caused by air pollution and particulates are making people increasingly fear for their health.

Action and participation is the antidote for what fear can create, a  feeling of helplessness. Our fears should create the will for political action on climate change and pollution. Even with the failure of our government and the EPA to protect the environment, we can still do it using market forces. The best plan is the carbon fee and dividend system as proposed by the Citizens Climate Lobby. The CCL legislative proposal would set an initial fee on carbon at $15 per ton of CO2 at the source and would increase it by $10 each year until the CO2 emissions were reduced to 10% of the 1990 US levels. The carbon fees are not a tax, as they would be rebated 100% to American households. It would give every American citizen a stake in conserving energy and reducing their use of carbon fuels,  which would both cut pollution and improve the economy. Exercise the power in your citizenship, and insist your Representative support action on climate change.

James Taylor: EDF's Top 10 Global Warming Lies – Or Not

Sun ,06/12/2015

 

James Taylor has published an opinion piece in Forbes about the Top 10 Global Warming Lies put forward by “climate edfalarmists”. The climate alarmists are the Environmental Defense Fund (EDF) as they recently sent out a mailer, “10 Global Warming Effects That May Shock You,”. The EDF’s  positions sound very much like the things you read in reputable news sources and peer-reviewed science articles, so it is hard to see them as lies. According to a search of Google Scholar, James M. Taylor has not published any research in peer-reviewed journals, but he has published numerous articles with the Heartland Institute. As one Forbes reader commented, “If you take the time to check Taylor’s linked references, you’ll find they are to his own articles, debunked papers, or to papers that don’t even support his conclusion or statement. It’s all smoke and mirrors!”

Smoke certainly. James Taylor once wrote articles for the Heartland Institute claiming that smoking and secondhand smoke were harmless. He has now turned his talents to writing articles that deny the effects of global warming. His work earned Forbes third place in the 2011 Environmental Hall of Shame contest. The award went to: ”Forbes Magazine (James Taylor) for a ridiculously misleading article, New NASA data Blow Gaping Hole In Global Warming Alarmism, that described climate scientists as “alarmist” 15 times. Award: A copy of the book Ethics And Journalism and a complete ban on ever using the words ‘alarmist’ again.”

Apparently neither he nor the Forbes’ editors paid much attention to the book on ethics, or the ban on using the word “alarmist” . This article uses the word “alarmist” more times than you would care to count. Forbes does now require that Mr. Taylor put a disclaimer on his articles saying that they are his own opinion. James Taylor is a lawyer and his client is the Heartland Institute and the fossil fuel companies they represent. His job is not to enlighten you, but to cause doubt about whether his client is guilty. Scientists publish their work in peer-reviewed journals along with the data that backs up their conclusions. If Mr. Taylor thinks they make mistakes, it is up to him to provide evidence that refutes their work. However, he does not do that as he has little  evidence. Links in his article take you to other articles he has written which sometimes have a few references to blog sites or occasionally an article in a magazine which has not been peer-reviewed for its accuracy.  As one Forbes reader commented,  “This paid propaganda brought to you by the donors to the Heartburn Institute. Enjoy it with a pack of cigarettes.”

To avoid confusion, I have listed what Mr. Taylor calls EDF’s Alarmist Assertions. This is followed by Mr. Taylor’s attempt to discount the EDF’s assertion, which is labeled Mr. Taylor’s Rebuttal . This is then followed by – Or Not which compares Mr. Taylor’s rebuttals  to reliable sources and peer-reviewed literature. It may take two packs for you to get through all this – or, you may just jump to the topics that interest you.

Alarmist Assertion #1 “Bats Drop from the Sky – In 2014, a scorching summer heat wave caused more than 100,000 bats to literally drop dead and fall from the sky in Queensland, Australia.”

Mr. Taylor’s Rebuttal: Objective science proves extreme weather events such as hurricanes, tornadoes, heat waves, and droughts have become less frequent and less severe as a result of the Earth’s recent modest warming.  … Global warming alarmists’ preferred electricity source – wind power – kills nearly 1 million bats every year (to say nothing of the more than 500,000 birds killed every year) in the United States alone.

– Or Not: Bat experts have noted that bats are very sensitive to high temperatures and Australia had its hottest summer on record in 2014. Research published in the Bulletin of the American Meteorological Society shows that global warming was responsible for making 14 natural disasters more extreme, including the Australian heat wave. His claim that that wind turbines kills more than 1 million bats every year is irrelevant and not supported by reliable research. His reference leads to a previous article he has written which referenced a self-published magazine article whose author came up with that number by using estimates from unpublished sources. Try following his references and see where they lead.

Alarmist Assertion #2  “Lyme Disease Spreads” – Warmer temperatures are contributing to the range expansion and severity of tick-borne Lyme disease.”

Mr. Taylor’s Rebuttal: Lyme Disease is much more common in northern, cooler regions of the United States than in southern, warmer regions…. Any attempts to claim global warming will cause a few more Lyme Disease deaths must be weighed against the 36,000 Americans who are killed by the flu each year. The U.S. National Institutes of Health have documented how influenza is aided and abetted by cold climate.

– Or Not:  This  Scientific American article describes how the vectors for Lyme disease are growing in the northern regions of North America and declining in the South – more evidence for climate change. The flu comment is just a red herring as flu is a communicable illness spread from person-to-person when cold weather brings more people in contact.

Alarmist Assertion #3 “National Security Threatened – The impacts of climate change are expected to act as a ‘threat multiplier’ in many of the world’s most unstable regions, exacerbating droughts and other natural disasters as well as leading to food, water and other resource shortages that may spur mass migrations.”

Mr. Taylor’s Rebuttal: The alarmists’ asserted national security threat depends on assertions that (1) global warming is causing a reduction in food and water supplies and (2) migrations of people to places with more food and water will increase risks of military conflict.

– Or Not:  The Department of Defense’s Climate Change Adaptation Roadmap  explains how our military leaders plan to address the reality of global warming.  CIA Director John Brennan offered a  candid assessment of the security issues:

Last year was the warmest on record, and this year is on track to be even warmer. Extreme weather, along with public policies affecting food and water supplies, can worsen or create humanitarian crises. Of the most immediate concern, sharply reduced crop yields in multiple places simultaneously could trigger a shock in food prices with devastating effect, especially in already fragile regions such as Africa, the Middle East and South Asia.

 A recent New York Times article explains that the drought caused by global warming was a major factor in triggering the Syrian civil war.

 Alarmist Assertion #4 “Sea Levels Rising – Warmer temperatures are causing glaciers and polar ice sheets to melt, increasing the amount of water in the world’s seas and oceans.”

Mr. Taylor’s Rebuttal: The pace of sea level rise remained relatively constant throughout the 20th century, even as global temperatures gradually rose. Also, the alarmist assertion that polar ice sheets are melting is simply false. Although alarmists frequently point to a modest recent shrinkage in the Arctic ice sheet, that decline has been completely offset by ice sheet expansion in the Antarctic. Cumulatively, polar ice sheets have not declined at all since NASA satellite instruments began precisely measuring them 35 years ago.

– Or Not: Studies have confirmed that more than 90% of the world’s glaciers are retreating and that Glacier National Park may become ice free in this century. Alsonote that Mr. Taylor does not claim that the sea levels have not risen, but that it is the pace of the sea level rise has remained constant,( i.e, the sea levels are most surely rising). The only reasonable explanations for this sea level rise are that the oceans are getting warmer and expanding – and that glaciers are melting and adding more water to the oceans.

Both the Antarctic and the Arctic are losing substantial amounts of ice. (See  #10 for an explanation about the Antarctic ice. ) As shown in the satellite pictures below,  the Arctic ice extent has declined about 35% in the last 30 years. You might wonder why Mr. Taylor would distort data which can be so easily checked . Apparently Forbes editors do not check such things.

Alarmist Assertion #5  “Allergies Worsen – Allergy sufferers beware: Climate change could cause pollen counts to double in the next 30 years. The warming temperatures cause advancing weed growth, a bane for allergy sufferers.”

Mr. Taylor’s Rebuttal:  Pollen is a product and mechanism of plant reproduction and growth. Indeed, NASA satellite instruments have documented a spectacular greening of the Earth, with foliage gains most prevalent in previously arid, semi-desert regions.

– Or Not: Pollen producing weeds such as ragweed are experiencing longer growing seasons and extending their ranges further northward. This is further evidence of climate change. Keep your antihistamines handy.

 Alarmist Assertion #6 “Beetles Destroy Iconic Western Forests – Climate change has sent tree-killing beetles called mountain pine beetles into overdrive. Under normal conditions those beetles reproduce just once annually, but the warming climate has allowed them to churn out an extra generation of new bugs each year.”

Mr. Taylor’s Rebuttal:  Alarmists claim warmer winters are causing an increase in pine beetle populations. This assertion is thoroughly debunked by objective, real-world data.

– Or Not: The extra generation of bark beetles each season has caused an exponential increase in their population causing a plague of bark beetles that in the last quarter-century has killed more than 30 billion pine and spruce trees from Alaska to New Mexico. Perhaps Mr. Taylor can explain why the plague of beetles started about the time winter temperatures began increasing in their range.

Alarmist Assertion #7 “Canada: The New America – ‘Lusher’ vegetation growth typically associated with the United States is now becoming more common in Canada, scientists reported in a 2012 Nature Climate Change study.”

Mr. Taylor’s Rebuttal:  Only global warming alarmists would claim that lusher vegetation and more abundant plant life is a bad thing.

– Or Not: Climate scientists point to this as further evidence that Canada’s climate is changing in response to global warming. It may be a bad thing for Canada, as much of the growth may be from invasive species.

Alarmist Assertion #8  “Economic Consequences – The costs associated with climate change rise along with the temperatures. Severe storms and floods combined with agricultural losses cause billions of dollars in damages, and money is needed to treat and control the spread of disease”

Mr. Taylor’s Rebuttal:  Severe storms, floods and agricultural losses may cost a great deal of money, but such extreme weather events – and their resulting costs – are dramatically declining as the Earth modestly warms.

– Or Not: Mr. Taylor needs to check with the large secondary insurance company Munich Re, which  has a department which studies insurance losses from natural catastrophes. Their graph below shows that while losses from geophysical natural catastrophes ( in red ) have remained relatively constant  over the past 35 years – the climate related catastrophes have increased about 2 1/2 times. Coincidence?

Alarmist Assertion #9 “Infectious Diseases Thrive – The World Health Organization reports that outbreaks of new or resurgent diseases are on the rise and in more disparate countries than ever before, including tropical illnesses in once cold climates.”

Mr. Taylor’s Rebuttal:   For example, DDT had all but eliminated malaria in the United States and on the global stage during the mid-20th century. However, environmental activists championed false environmental accusations against DDT and dramatically reduced use of the life-saving mosquito killer throughout much of the world.

– Or Not: The World Health Organization reports that, “though global warming may bring some localized benefits, such as fewer winter deaths in temperate climates and increased food production in certain areas, the overall health effects of a changing climate are likely to be overwhelmingly negative. ” Who should you believe, the World Health Organization or Mr.  Taylor? He claims that the real problem is that we are not using DDT anymore, but he is apparently not aware that insects built up a tolerance to it. Since he was quite concerned in #1 about wind turbines killing bats and birds, should he not be concerned that DDT almost wiped out many species of birds, including Eagles in North America?

Alarmist Assertion #10  “Shrinking Glaciers – In 2013, an iceberg larger than the city of Chicago broke off the Pine Island Glacier, the most important glacier of the West Antarctic Ice Sheet. And at Montana’s Glacier National Park glaciers have gone from 150 to just 35 over the past century.”

Mr. Taylor’s Rebuttal:  Calling attention to anecdotal incidents of icebergs breaking off the Antarctic ice sheet, while deliberately ignoring the overall growth of the Antarctic ice sheet, is a misleading and favorite tactic of global warming alarmists.

– Or Not:  There are two processes occurring in Antarctica. The warmer oceans around Antarctica are causing more snow to fall on the mountains in East Antarctica, so the glaciers there are growing. The warmer oceans are also eroding the ice sheets in West

Antarctica, causing ice loss and huge icebergs to break off.  The GRACE satellite data at the right shows that overall the mass of ice in Antarctica is declining.The extent (or area) of the Antarctic ice is irrelevant as the area of thin ice sheets grow and shrink with the seasons and the weather.

If glaciers are not melting and the oceans are not warming, then Mr. Taylor needs to explain what is causing the sea levels to rise.

 

 

Paris: Mr. Taylor uses a word “alarmist” as a pejorative to discount what the scientists are saying, but it is one of the few things he has right. Climate scientists are very alarmed that the world is on a path to end civilization as we know it by 2100, and that he, Forbes, the Wall  Street Journal, Investor Business Daily, and our Congress is in denial. Here is what will happen to the world if we do not listen to the scientists and take binding action at the Paris Climate Conference. The graph below charts three paths, no action on carbon emissions, current commitments in red, and the path we need to be on if the world as we know it is to survive. Which path would you choose?Temp paths

Newsflash: The Earth's Temperature Is Still Going up

Wed ,04/11/2015

Conservative politicians and columnists like to say,”The Earth’s temperature hasn’t gone up since 1998″. That is certainly wrong, and creates doubts about them actually being “conservative”. Just a few weeks ago my Congressman said in a letter, “The Earth’s temperature hasn’t gone up since 1997”, stretching it a bit. That’s his excuse for not supporting action on climate change.

That untruth about the Earth’s temperature was popularized by George Will when he used it to attack John McCain during the 10warmest2008 election. George Will was apparently upset that a conservative Republican was recommending action on global warming. When I contacted George Will for an explanation, he said that 1998 was the warmest year on record and no year since had been hotter. Actually 2005 was, destroying his argument. There have been several warmers years since – as shown in the graph at the right. And so far, 2015 is setting a new record.

Not willing to give up on a good excuse, the politicians and pundits now claim the International Panel on Climate Change (IPCC) has confirmed their deception. That’s not right, either. The IPCC’s Fifth Assessment Report  stated that the global surface temperature “has shown a much smaller increasing linear trend over the past 15 years [1998-2012] than over the past 30 to 60 years.” The apparent slowdown was termed a “hiatus” and cheered by the Skeptics, although a “smaller increasing linear trend” is not a hiatus. And it turned out that the “smaller increasing linear trend” was caused by a change in the way the Earth’s temperature was measured, not by an actual decrease in the rate of warming.

Dr. Tom Karl, director of the National Centers for Environmental Information,  is the lead author of the  study published in the journal Science. He explained the discrepancy came from a change in how ocean temperatures were measured. “Global ocean temperatures are estimated both by thousands of commercial ships, which record the temperature of the water entering their engines and by thousands of buoys. The buoys tend to get cooler temperature readings than the ships, likely because ships’ engines warm the water. Meanwhile, in recent years, buoys have become increasingly common.”  The result, Karl says, is that the oceans did not appear to be warming as much because more buoys are now being used instead of ships. So Karl’s team adjusted the buoy data to make them line up with the ship data. The corrected data,  shows that since 1998, the rate of warming is about the same as it has been since 1950: about two-tenths of a degree Fahrenheit per decade.

That should settle the matter but some politicians just are not willing to accept science  and, interestingly enough, one of them is the chair of the Congressional Science Committee.  Congressman Lamar Smith (R-TX), chair of the House Committee on Science, Space, and Technology, has spent much of the last few years pressuring the National Science Foundation to ensure that it only funds science he thinks is worthwhile and “in the national interest.” He certainly didn’t think that Dr. Karl’s research,  showing the Earth’s temperature was still going up an alarming rate, was in the national interest. So, he sent a request that Dr. Karl and NOAA provide his office with “[a]ll data related to this study and the updated global datasets” along with the details of the analysis and “all documents and communications” related to part of that analysis.

The request was meant to be burdensome, but apparently Congressman Smith does not understand how science publications work. NOAA responded to Rep. Smith’s request by pointing him to the relevant data and methods, all of which had already been publicly available. Undeterred, Representative Smith asked for even more data, explanations, and communications. NOAA did not respond to that request or the following subpoena, citing a “confidentiality interest”.   Committee Member Bernice Johnson (D – TX), intervened  with a letter sent to Rep. Smith revealing and criticizing his actions. In it, she noted that Rep. Smith was looking into a scientific study and not a Federal policy decision. “As such,” she wrote, “this is not an area of delegated legislative authority by Congress  (unless you are proposing that Congress should somehow legislatively overrule peer-reviewed scientific findings).” Of course that is what Rep. Smith would like to do, but he will likely have to content himself with just harassing Dr. Karl and NOAA.
