Climate Change: What We Know

Sun ,30/03/2014

The science Skeptics dispute almost every discovery by climate scientists, and the facts are often lost in the disputes. This is a guest article by Rachel Martin which summarizes nicely the AAAS report meant to separate what scientists know from the misinformation:

I’ve just found this great interview with Richard Alley, a glaciologist at Pennsylvania State University, and he is a delight to listen to. If I were making a movie about some impending catastrophic event which included a part for an honest and dedicated scientist whose role was to alert the human population, I would pick Richard Alley. He just really looks and acts the part which I realise is a dumb thing to say because he really is the part! I just think he does a great job.

The interview, which is less than 9 minutes, is a part of the American Association for the Advancement of Science (AAAS)What We Know initiative which is to try to communicate to the public that human-caused climate change is happening, that it carries dangerous risks and that the sooner we act the lower the costs will be.

The “What we know” initiative has three key messages they want to communicate:

1. Climate scientists agree: climate change is happening here and now.

2. We are at risk of pushing our climate system toward abrupt, unpredictable, and potentially irreversible changes with highly damaging impacts.

3. The sooner we act, the lower the risk and cost. And there is much we can do. Waiting to take action will inevitably increase costs, escalate risk, and foreclose options to address the risk.

The AAAS has released a full report specifically aimed at a large audience to address the myth that the scientific community is divided on the issue of climate change. It explains how climate change is and will affect your life. It can be read here.

 

 

The Beauty and Power of Wind Energy

Wed ,12/02/2014

Before fossil fuels, wind was man’s major source of power for sailing ships, grinding grain, and pumping water.  The beauty of ships and windmills were an endless source of inspiration for painters and photographers. Windmills were once the source of power for providing water in rural America, such as the one in the picture with the giant wind turbines towering over it. Though some criticize the wind turbines for being unsightly, they have a majestic beauty of their own. Their real beauty is in their utility as,  windmill4once built, there are no fuel costs or emissions. Much of the criticism of wind power has come from the fossil fuel industry, as it is hard to compete against a technology with no fuel costs and few  regulatory problems.

Fossil fuels now have a near monopoly on providing energy, and consumers would benefit from more competition in that market. Fossil fuels have served us well and we will certainly need them far into the future – even to develop sustainable energy sources.  But there is a trap if we wait too long, as the rising  price of traditional fuels will also increase the cost of  building the renewable sources,  possibly leading to an energy shortage before renewable sources can make up the difference.

Cost: As the cost of building new coal fired plants has increased prohibitively, a number of US power companies have taken advantage of wind energy to  increase the supply to their customers and lower their costs.  Recently, AEP/PSO  in Oklahoma was able to meet the demand caused by the heat wave in 2012 by bringing 200 megawatts (MW) of wind energy online. It recently planned to purchase 200 MW more, but took advantage of an opportunity to contract for an additional 600 MW of wind energy from facilities being developed in northwestern Oklahoma. AEP/PSO said the cost was now less than building new coal fired plants, and that the purchase will save an estimated $53 million in the first year and even more thereafter. The declining cost of wind energy is making it competitive to natural gas as well. Wind contracts in Texas, about one quarter of all US installations, are now regularly below $30/MWh. Even with a tax incentive, this still puts wind well below $50/MWh, while the comparable cost for a new gas plant is above $60 /MWh. New design and siting where there are good wind conditions allows Texas wind farms to get capacity factors around 50%. Nearly half of that occurs during peak load, defying characterizations of wind as essentially an off-peak power source.

Capacity: One criticism of wind energy is that it will not be able to supply enough power to replace the fossil fuel sources.  WindWind currently supplies about 3% of the worlds electricity and is growing 25% each year, meaning that it will double about every three years.The graph on the right shows the worldwide growth of wind power. Last year, wind farms in the U.S. generated 60,000 megawatts of energy, enough to power 15 million homes, and provided 81,000 jobs nationwide. Another criticism, based on a misunderstanding, is that there is not enough available space. Each windmill requires about about 14 acres of air space to insure they do not interfere with each other but they  require much less land space,  about 0.3 acres per turbine. Landowners can use the area below the windmills for farming or livestock, and they are compensated by a 5% royalty, about $3000 to $5000, as  each turbine generates about $80,000 in electricity.

Startup costs: To compare the costs of building new plants, the levelized costs of primary energy sources have been estimated for different regions  of the country. CostLevelized costs include all the costs of building a new plant and running it for a 30-year cost recovery period, regardless of the expected lifetime of the plant. Wind turbines may have a much longer recovery period, as some windmills in Holland have been operating for two centuries, though some of the gears are made of wood.  Though the table show some types of gas fired plants to be less costly that wind energy, the levelized costs do not include external costs, i.e.,  the costs indirectly borne by society. The external costs for fossil fuels do not include health and environmental damage from particulates, nitrogen oxides, sulfur oxides, chromium, mercury, arsenic, and carbon emissions. An EU funded research study, Externalities of Energys ,  found that including externalities would increase the cost of producing electricity from fossil fuels by a factor of 30% for natural gas to about 90% for coal, if costs to the environment and to human health were included. If we include the  costs of letting fossil fuel release  their waste products into the environment, then sustainable energy sources have a big cost advantage.

Criticisms: The  intermittency of the wind is a problem, as is the lack of a way to store the energy. Putting wind electricity into the power grid solves some of the problem, as conventional sources can take up the slack. Each unit of wind energy put on the grid saves about three times as much in fuel energy, as conventional plants are only about 30% efficient. Better storage technology is under development , but conventional sources will be needed  as backup in the mean time.

Wind turbines are also criticized, somewhat unfairly, for their noise and for bird deaths. The noise underneath a well maintained turbine is not much louder than from the wind turning it. The turbines are responsible for bird deaths, but they are not among the top ten human causes of bird mortality. A peer reviewed Canadian study of bird mortality finds that less than 0.2% of the population of any bird species is currently affected by mortality or displacement by wind turbine development. The study concluded that even though the number of windmills are projected to grow ten times over the next two decades, “population level impacts on bird populations are unlikely, provided that highly sensitive or rare habitats, as well as concentration areas for species at risk, are avoided.”

Subsidies: While once the problem was getting electricity to rural America, the problem now is getting wind electricity from rural areas to population centers. It will require a large investment in research and infrastructure to develop wind energy. As Washington struggles to balance the U.S. budget, possible cuts in subsidies has created an uncertainty hindering investments in wind energy. While it is the national interest to subsidize the development of sustainable energy resources, a much larger share of tax breaks go to well established and profitable fossil fuel companies. The United States’ yearly subsidies to the fossil fuel industries amounts to about $13.6 billion, while all renewable energy subsidies together amount to about one sixth as much.

Our energy needs will best be served by a mixture of traditional and alternate energy sources, and we should not let unfair criticisms or politics keep us from developing the alternate sources.

Wind Energy and Bird Mortality

Tue ,07/01/2014

 

A rather curious letter recently appeared in the Tulsa World Editorial page titled Wind Turbines, by Jim Wiegand, Redding, CA.  Mr. Weigand has no ties to Tulsa, yet the editor published it and added a note: “Wiegand is a nationally recognized wildlife biologist and expert on the effects of wind turbines on birds.” The letter started with, “The wind industry is hiding massive turbine-related bird and bat genocide. The industry has created fraudulent mortality studies and been given voluntary guidelines in order to hide its slaughter.” The letter never mentioned birds again but went on into conspiracy theories and a criticism of wind energy.   

 Wind-turbines do sometimes kill birds and bats, but bird genocide? In other of his writings, Mr. Wiegand claims windmills are responsible for dozens of Whooping Crane deaths, and that wind turbines will cause their extinction within five years. So far, there is not one Whooping Crane death that can be attributed to windmills.  Carla Gilbert, in a post to the article, disputed the danger to similar birds. “When I was traveling in Portugal a number of years ago we could see many wind turbine farms from the highway. We were informed that the storks like to build their nests atop them. When the bus stopped for refueling I took pictures of the storks sitting on their nests atop the turbines and saw several storks coming and going from their nests. I did not see any injured or dead birds.” And, the storks are not becoming extinct as a result of the windmills. One falconer, who was at first worried about the windmills, now puts his falcon boxes on wind turbines and does not consider them a greater threat to birds than his picture window.

There has been considerable opposition to windmills and of renewable energy in general, so it is difficult to know whether all the criticisms are factual. Studies have found about an average of five to eight dead birds per windmill. That is about the number of birds who do themselves in on a picture window each year. When you add in the birds killed by cars and by hunting, it would seem that man’s other activities are a greater threat to the birds than wind turbines. For birds, the main threats are windows, cars, climate change, disease, hunters and pesticides.

There is a concern for protected species such as lesser prairie chickens and eagles. There are severe penalties for harming eagles, so to be on the safe side, the owners’ of windmills apply for permits to legally kill eagles. That has caused quite an outcry, but recently, the government gave the companies a 30 year moratorium on enforcing protection laws, while they study the problem. HPIM2053aIt does not seem likely that an eagle would fly into a windmill, particularly since another criticism is about the noise windmills make. Still there are confirmed reports that 85 bald eagles were killed by windmills in the past five years,  about 17 per year. Eagles are at the top of the food chain, so any environmental pollutant is likely to harm them, and DDT was the main cause of their population decline. Once DDT was banned and eagles became protected, their population recovered to about 140,000 in North America. They have been taken off the threatened species list. They are harmed by many pollutants associated with energy production – about 280 were killed by the Exxon Valdez oil spill. It is a shame when one of the magnificent birds is killed by accident, but if we cut out any activities that might harm them, then we would have to cease much of our energy production.

The concern about the lesser prairie chicken is that they avoid tall structures, and windmills might cause them to move from their normal habitat. Prairie chickens gather to mate each spring in large communal areas called leks. One enterprising oil company, opposed to wind power, drove a group of reporters up to a lek in the Osage Hills. They wanted to show the reporters what might be lost if windmills were built there, as if driving a van full of reporters around their lek is not going to disturb them. Many of the problems with wildlife and noise could be addressed by where the windmills are sited, and reasonable laws are needed to see that the windmills will disturb animals and people as little as possible.

Research finds the actual evidence of bird kills by windmills to be greatly exaggerated. In the Journal of Applied Ecology Volume 49, Issue 2, pages 386–394, April 2012, the authors found the impact of wind farms on bird populations to be minimal with the greater impact being during construction than during subsequent operation. A comprehensive study of bird mortality in Canada found most human-related bird deaths (about 99%) are caused by feral and domestic cats, collisions with buildings and vehicles, and electricity transmission and distribution lines.  A related peer reviewed Canadian study of bird mortality says their data suggests that less than 0.2% of the population of any bird species is currently affected by mortality or displacement by wind turbine development. They concluded that even though the number of windmills are projected to grow ten times over the next two decades, “population level impacts on bird populations are unlikely, provided that highly sensitive or rare habitats, as well as concentration areas for species at risk, are avoided.”

Mr. Wiegand’s letter is mostly fiction. A search shows that Mr. Weigand has a degree in biology from the 1970′s and makes his living by selling antiques.  He has done nothing that would qualify him as an expert in wildlife biology, and none of his claims, here or elsewhere, are backed by credible research. His avocation is writing letters to newspapers and posting comments on websites critical of wind energy. Some people can’t see the value, or the beauty of windmills, and they look for any excuse to criticize them.

Global Warming and Pine Beetle Damage

Tue ,24/12/2013
IMG_0246

Click to enlarge images.

On an environmental science field trip to the Cibola National Forest east of Albuquerque, the students noticed a large number of dead pine trees. The picture shows one that had been cut down, with the wood looking as if it had been shot full of holes with buckshot. The park ranger explained that the trees had been killed by the pine bark beetles which, because of climate change, have been extending their range to higher elevations in the park. The tree’s natural defense against the beetles is a secretion of pitch which forms a gooey protective barrier against beetles. The pine beetles do the most damage to mature trees that grow slower and produce less pitch, particularly when stressed by warmer temperatures and drought.

The quarter inch long beetles bore into the bark on mature trees and and create galleries in which they mate and lay eggs. The grubs feed in the inner bark and cambium layer, enlarging their tunnels as they grow. The “S” shaped tunnels can eventually girdle and kill the tree.  Mature larvae move to the outer bark and create a cell in which they pupate. When the new adults hatch, they chew through the bark, leaving small, clearly visible exit holes.  Most of the pine beetle damage is to the outer layer so the trees can still be used for lumber if harvested soon after the tree dies. Wood from beetle-affected trees retains its commercial value for 8 to 12 years after death, but the value drops rapidly during the first several months, as rapidly escaping moisture causes the wood to crack. The beetles also often introduce a blue stain fungus that can be lethal to the tree. Blue staining of the wood from the fungus is considered a defect, leading to a lower market price.

Normally, mountain pine beetles spend a winter as larvae in trees before emerging as adults the following summer. cycleIn the last two decades at the Colorado University Mountain Research Station, mean annual temperatures were 2.7 degrees Fahrenheit warmer than they were in the previous two decades. They found “The number of spring days above freezing temperatures increased by 15.1 in the last two decades, and the number of days that were warm enough for the beetles to grow increased by 44 percent since 1970.” This allows the beetles to produce an extra generation during most summers, leading to a rapid increase in the beetle population. The current bark beetle epidemic is the largest in history.

The bark beetles are a factor in wildfires as the large number of dead trees provide fuel for the fires. The needles stay on the trees for 2 or 3 years, contributing to canopy fires.  After the needles fall, the bare trees  contribute less to fires, but then they allow more sunlight through which melts the snow cover earlier and encourages the growth of underbrush, providing more fuel for wildfires. Compared with decades past, the traditional fire season now lasts two months longer in the West. The loss of trees also leads to earlier melting of snow which causes earlier runoff, contributes to heavier spring floods, and makes less water available later for streams and irrigation.

Because of global warming, the bark beetles have extended their range northward and to higher elevations, and their population is growing.  Andrew Nikiforuk, a Canadian journalist, has chronicled the 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. Though there are other factors, such as how the forests are managed, climate change is by far the greatest factor. Trees stressed by heat and drought can’t mount a strong defense against the beetles, whose numbers grow exponentially when they produce more than one generation per season. In one area in Canada, the bark beetle hatch produced a cloud of the insects large enough to show up on radar.

And it is not just in the West. The southern pine beetle is now spreading through New Jersey’s famous Pinelands. According to the article, “The tiny insect, firmly entrenched, has already killed tens of thousands of acres of pines, and it is marching northward. Scientists say it is a striking example of the way seemingly small climatic changes are disturbing the balance of nature. They see these changes as a warning of the costly impact that is likely to come with continued high emissions of greenhouse gases.”  Though New Jersey has warmed by about 2.3 degrees Fahrenheit over the past century, it is the winter low temperatures that are most important. Nights must get to about 8 degrees below zero to kill the beetles. The New Jersey climatologist’s office calculates that such bitter nights used to happen several times per decade in the state. The last night that cold in the Pinelands was in 1996, and the beetle outbreak was first noticed five years later.

Though global warming usually focuses on high temperatures, the graph shows that there is also an increase in the average nighttime temperatures. Record highsThe coldest nighttime temperatures are the main determinant in the geographic range of bacteria, fungi, insects, and invasive species. Those who do not wish to address the problem of global warming often ignore those small things, one of which is the bark beetle. Besides the economic loss of billions of trees, there is an aesthetic loss in the beauty of the forests. The tree loss contributes to wildfires, problems with water management, and loss of food and habitat for many species that live in the pine forests. Those who claim it will cost too much to reduce our carbon emissions, do not consider the cost of not addressing the issue. The pine bark beetle is an example of but one of the many costly things that should be included in their balance sheets.

Media Bias: Why the Public Is Confused about Climate Change

Mon ,16/12/2013

The Tulsa World article ,”Global warming poll finds broad divide more political than scientific,” attempted to explain why the public and politicians are confused, not only about the issue, but about what scientists think.  Polls of climate scientists find a strong consensus on the issue , with  97 percent of scientists actively engaged in climate research agreeing that man’s activities are the main cause of global warming. Fearing a loss of profit if CO2 is regulated, there has been a well-funded effort to spread doubt about the scientific consensus. And some media sources are willing accomplices.

 The media has helped spread the doubt by treating the issue as a legitimate controversy, when there is very little controversy among scientists. At one time the Tulsa world was courageous enough to point out in an editorial that it was scientists who say that global warming is real and politicians who say that it is a hoax. However, the Tulsa world has changed ownership and the new managing editor has adopted a bias which he calls “reflecting Oklahoma values. “ The Tulsa World often publishes comments from readers in its editorial page, and though there were a number comments reflecting the scientists’ viewpoint, the editors added to the confusion by publishing only two comments from one side, and none representing scientists.

One comment tried to explain away the strong consensus among scientists by claiming that scientists find what they do because of money the research generates. However, climate and weather research is vital to our national interest and would be funded no matter what the scientists found. Climate scientists usually work at universities and government laboratories, where salaries range from $50,000 to $120,000. Research grants are awarded on a competitive basis, and most of the money from the grants goes for research expenses and little to the scientists. Their published results are held to a high peer review standard to ensure that the methodology is sound and the conclusions are consistent with the evidence. The amount of money they get is certainly not worth taking a chance on ruining their reputation and career.

The second comment claimed that the Earth’s systems are just too complicated to understand, and therefore climate scientist can’t know what they are talking about. That is the old Skeptic’s argument that if you don’t understand everything, then you understand nothing. In spite of the complexity, scientists have been able to identify the main factors that affect our climate. Greenhouse gas theory was developed in the 19th century, and after examining the natural and human caused factors that affect our climate, climate scientists have concluded that the main factor in global warming is man’s release of CO2.

The human body is also very complex, but medical scientists have identified a major risk factor to health be smoking. Yet, for many decades, tobacco companies were able to deny the scientific evidence that showed the link between smoking and coronary disease. Climate scientists have identified the major risk factor in climate change to be man’s emission of CO2 and warn of the danger to the environment that sustains us. However, like smokers who ignore their doctors, many people are unwilling to listen to the scientists’ warning. Would the Tulsa World, and other media sources, now be willing to treat the dangers of smoking as a legitimate controversy?

Climate Change: A Letter to Congressman Lucas

Sat ,07/12/2013

This is a letter I sent to Congressman Frank Lucas (R – OK) on August 5, 2013. I asked him at his town hall meeting on November 7, 2013 if he had received it, and he could not recall it. It was a 15 page letter which contained anecdotal evidence plus the latest evidence from climate research in full color pictures and graphs. In case he misplaced it, I have reproduced the letter here in hopes he might run across it while looking for my write-up on his town hall meeting. It would seem that this information would be of vital interest to him as he is Chairperson of the Agriculture Committee, charged with the security of our food supply. 

 

Dear Congressman Lucas,

I’m sure you’re aware of the Pearson drought index which shows that most of Oklahoma, much of the Southwest United States, and much of the Earth’s land area where food is grown  is under moderate to severe drought conditions. It seems that lately the coastal areas of continents have been receiving more rainfall while the interiors have been experiencing more drought. I’ve lived in Oklahoma most of my 70 years and in my recollection, it seems that we are now seeing heavier rains in the spring and longer and more frequent droughts in the summer.

  My family has lived in Oklahoma since statehood and I have a number of anecdotes about how the climate is changing. Our Thanksgiving family photo in 1998 was taken in front of one of my Dad’s apple trees, which still had green leaves. He remarked at the time that he had never seen frost come so late, and he was 88 at the time. A few years ago our plant hardiness gardening zone was changed from a 6 to a 7, acknowledging later frosts and warmer winters. Armadillos are now abundant in Oklahoma, though there were none here when I was growing up.

 Anecdotes do not serve as proof, but they do raise questions about what the theories and evidence is saying. The greenhouse gas theory is solidly based upon the laws of physics. Though greenhouse gases comprise only 1 to 3% of the atmosphere, depending on the humidity, they are responsible for the Earth being about 33°C warmer than its would be without them. It seems reasonable that an increase in the greenhouse gases would cause the Earth to warm. Though water is by far the most abundant greenhouse gas, its concentration in the air is limited by its saturated vapor pressure. Carbon dioxide, though less abundant, absorbs strongly in the infrared and is not restricted in concentration as water is. Studies of the ice ages have identified carbon dioxide and changing solar irradiance as being the main factors in determining the Earth’s temperature.

 We are now putting about 30 billion tons of carbon dioxide into the air each year and measurements show that the concentration in the air is increasing. The increasing partial pressure of CO2 is causing more to dissolve in the oceans, decreasing their pH by about 0.1 pH unit.  That doesn’t sound like much, but the oceans are a carbonate buffer system and that translates into the oceans now being more than 20% acidic, threatening, shellfish, corals, and the plankton which convert much of the ocean’s carbon dioxide back to oxygen.

Biologists have observed that some species are migrating northward and to higher altitudes. There is evidence that glaciers are receding and that ice at the poles is declining. The declining extent of sea ice in the Arctic seems to be affecting the jet stream, which greatly affects our weather patterns. Though it is not possible to prove that global warming is the cause of any one weather event, it likely has an effect on most of the weather events that do occur, since the amount of energy and moisture in the air are the main determinants in weather events.

 There are always uncertainties in scientific measurements, and even greater uncertainties in predictions about the future. It is always possible to dispute any one piece of evidence based upon those uncertainties, but when a large number of independent measurements lead to a similar conclusion, the confidence level increases – but never reaches 100%.  I hope you will examine the evidence presented in the rest of this letter and agree that the preponderance of the evidence shows that we should take some action to address climate change.

 Republicans have a history of being strong advocates for science, environmental responsibility, and sound fiscal policy. Nixon created the EPA, Reagan signed the Montréal protocol limiting fluorocarbons and used cap-and-trade to reduce greenhouse gas emissions blowing into Canada, and archconservative Barry Goldwater once said that, ” The persistent myth that conservation and environmental protection are liberal causes continues to be perpetuated by the media, liberals and many self-professed ‘conservatives’. The truth is that conservation and environmental stewardship are core conservative values”.

 I hope you will examine the evidence presented in the rest of this letter and consider taking a leadership role in addressing the climate change issue in a manner that is consistent with Republican principles. In many ways, the world’s food supply is at risk.

The 2012 Environmental Hall of Fame/Shame Winners

Mon ,16/09/2013
Earthrise2
This year the Environmental Hall of Fame/Shame contest was carried out on three websites and the votes were combined to determine those who have most affected the environment through word or action.

The 2012 Environmental Hall of Fame Winners:

The winner is President Barack Obama, with 45% of the votes, for his efforts to protect the environment through executive action, such as  mileage standards and addressing air pollution through EPA action.  Award: A little coöperation from Congress, so please write your Representatives.

Runner-up was Dr. Jennifer Francis(36%) for her ground-breaking work tying the loss of Arctic sea ice to a slowing jet stream, deep Rossby Waves, and the resulting (rapid) rise in stalled weather patterns. Article  here.  Paper here: Evidence linking Arctic amplification to extreme weather in mid-latitudes Award: A growing awareness of the link between global warming and severe weather events.

Tied for 3rd and 4th was Neven ( 9%), an amateur scientist, for his Arctic Sea Ice blog . It is a highly accessible blog  focused like a laser on a major planetary system in rapid collapse - bringing it to the attention of an increasing number of people and the media. It includes some amazing computer animations of Arctic satellite imagery and scores of insights from a good number of researchers. Award: A massive number of visitors to his blog.

 The tie was with Arnie Gundersen (9%), for having the courage to broadcast information being censored by main stream media about environmental problems caused by Fukushima nuclear reactors.  Award: A picture of Japanese girls with a signed note thanking him for standing up for them.

The 2012 Hall of Shame Selections:

First place goes to Donors Trust and Donors Capital Fund  (56%), both who fund climate denial activities while allowing donors to remain anonymous and hide their vested interests. According to Robert Brulle on PBS Frontline , “by 2009, about one-quarter of the funding of the climate countermovement of climate change denial is from the Donors Trust and the Donors Capital Fund.”   Prize: An IRS investigation of their of their tax-exempt status.

Runner up was  Dr. James Wanliss (Cornwall Alliance) (22%) ”for equating people who consider the Earth more important than SUVs with those who consider the Earth to be more important than God or our fellow human beings”. The Cornwall Alliance, who published Dr. Wanliss’ book , claims that stewardship is a Green Dragon trying to corrupt the true meaning of religion.  Prize: An opportunity to clean up the mess they helped make of the Earth, as described in this article.

There was a tie for 3rd and 4th place between The Professional ENGO, Green Washer/Opportunists (9%), that use climate change as an agenda tool for political gain. Particularly those on this list which still invest in fossil fuels.  Prize: Worthless paper as their investments lose value as we switch to sustainable resources.

and

Japanese Prime Minister Noda (9%),  for dumping the “Zero Nuke” policy.Prize: A partly filled out employment application for work at TEPCO’s Fukushima No. 1 where there is a labor shortage. 

It is important that we keep in mind those who are heroes and villains to the environment. I wish to thank those who provided the nominations, the prize suggestions, the insightful and often humorous comments, and the votes to determine the winners. As this year goes by, please take note of those you wish to nominate for the 2013 awards.

Global Warming: The North Carolina Solution

Comedians and late-night talkshow host have had a lot of fun with North Carolina’s solution to the rising sea levels caused by global warming. The legislature passed a law to deal with it.

HB 819 : North Carolina lawmakers recently passed HB 819, which included a four-year moratorium on the state Coastal Resources Commission authorizing any sea-level forecast to be used as the basis for regulations while the issue is studied. “North   Carolina should not ignore science when making public policy decisions,” Governor Bev Perdue said. And then she ignored science by refusing to veto HB 819, allowing it to come become law. Any time a law forbids scientific research, you can be sure there is a special interest group behind it.

Special interests: A group called NC-20 claims that floodplains should be determined by historic trends which suggest the seas will only rise 8 inches this century, rather than the scientific data which projects three times that . Republican Rep. Pat McElraft explained,“What we have done is ask them to use a blend of models, to use historical data, to use some real science that we can all trust when we start making laws here in North Carolina”. McElraft, who is a former real estate agent, denied that campaign contributions ever influence her. However, the largest industry contributors to McElraft’s campaigns have been the North Carolina Association of Realtors, followed by the North Carolina Home Builders’ Association. And you can be sure that when politicians say “real science”, it is usually to get around acting on what is actually, real science.

Real Science: Scientists have found that the sea levels have been rising in response to thermal expansion of the ocean and the melting of glaciers. The graph below shows that sea levels have been rising about 3.2 mm per year, which is about 14 inches per century:

The graph above represents the average rise in sea level over the Earth. However, global warming does not cause the sea levels to rise everywhere at a uniform rate and they are rising much more quickly along the Atlantic Coast of the United States, as shown in the graph below:

The U.S. Geological Survey recently released a study that shows the East Coast from Cape Hatteras to Boston has already seen a sea level rise three to four times higher than most of the world in the past 20 years, and will likely continue to do so. The North Carolina Coastal Resources Commission’s 13-member panel of scientists conducted a nine-month study and warned in 2010 that sea levels in North Carolina could rise by more than 3 feet by 2100 and threaten more than 2,000 square miles of coastal land.

Enter HB 819: There is some very expensive real estate on the Barrier Islands and along the coast of North Carolina that is only a few feet above sea level. Sea level rise threatens the value of that property and makes it more vulnerable to storm surges from hurricanes. Real estate developers might be prohibited from building –  or rebuilding homes damaged by hurricane Sandy and Irene – if low-lying areas were to be designated as a floodplain by the North Carolina Coastal Resources Commission. As an insurance adjuster in North Carolina explained it, “ NC has dumped the coastal flooded homes on the National Flood Insurance Program for years. They build the homes in a predicted floodplain. Lo, and behold the homes on the coast are flooded. The Feds then have to pick up the tab for NC building homes in known floodplains. They are even today rebuilding homes where they were flooded previously in the exact same spot – in an ocean floodplain.”

It’s a sweet deal, the North Carolina developers and builders profit by building homes in the floodplain, and the federal government picks up the tab when the homes flood. Apparently the legislature is not going to let a little science interfere with that sweet deal.

Global Warming: Misguided Comments about the Northwest Passage

Mon ,19/08/2013

There was recently an article about global warming  in the Tulsa World which took an interesting approach to the topic. It was an article from two Earth scientists which started , “As climate researchers from divergent political leanings we regularly hear misguided comments about global warming. To help move the dialogue forward we offer a brief response to the top 10. “  They went on to agree that the Earth is warming, that carbon dioxide is the main cause, that we are causing undesirable changes in the environment, and that we should leave things as best we can for future generations.

Probably the most relevant quote in the article is, “As climate researchers from divergent political leanings we regularly hear misguided comments about global warming.” Many of those misguided quotes come from anti-science websites like those of Anthony Watts, Roy Spencer, or Steve McIntyre’s. They use a little information which may be true but they do not tell you the rest of the story which puts it into perspective.

For instance, many anti-science web sites make a lot of the fact that the Northwest Passage was navigated around 1936. Satellite pictures show that since 1979, the extent of the Arctic sea ice has declined by about 40%. The claim about the Northwest Passage being open in 1936 is an effort to discount that by trying to show that in 1936he Arctic Ocean was open water. That was certainly not true, as the few early passages made then were with the help of icebreakers. You can get a better idea of how the Arctic Ocean is changing by looking at the actual shipping records:

Commercial Shipping on the Northern Sea Route 5,Table 1

Year    Cargo,Thousands of Tons   Length of Season

1935                246                               93 days

1940                289                              93 days

1950                503                              122 days

1960                1013                            128 days

1970                2400                            140-150 days

1980                4951                            year round for western section

1987                6579                            year round for western section

The data certainly paints a different picture and it is interesting that none of the anti-science websites bothered to mention it.

You may have also heard one of the many versions of the story that, “the Earth hasn’t warmed in the last 15 years”. The anti-science sites got that from a BBC interview with Phil Jones, director of the British Climate Research Unit (CRU). The BBC interviewer asked Do you agree that from 1995 to the present there has been no statistically-significant global warming?” Dr. Jones repliedYes, but only just. I also calculated the trend for the period 1995 to 2009. This trend (0.12C per decade) is positive, but not significant at the 95% significance level.”  Dr. Jones went on to explain that the result was not “statistically significant” because of the short time period.

Dr. Jones is often quoted but somehow the “statistically significant part” is omitted. You can prove a lot of untrue things about the Earth’s temperature by using using carefully selected or short time periods. For instance, if I were to choose the 16 years from 1982 to 1998, I could show that global warming has gone up by a whopping 0.31°C per decade. That, of course, is not statistically significant either. It takes about 30 years to average out the effects of natural variations and, over the last 30 years, the Earth has warmed about 0.15°C per decade.
