Climate Change: What We Know
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.
