Understanding climate change is challenging. Many people feel that because they are not scientists climate change is beyond them. In fact, part of the challenge in understanding climate change is that it's one of these complex issues, like the "green economy," that can quickly become overwhelming. Although having a science background is certainly useful to get an in-depth scientific understanding of the climate change issue, everyone can get educated about the environmental, economic, and social implications of this important global issue. Then, we have a better idea of ways in which to act.
To this end, I want to point to two websites that I've found particularly useful in understanding and keeping up to date with topics related to climate change.
1) CAMEL (Climate, Adaptation, Mitigation, E-Learning); An incredibly well-reserached, free, resource for educators.
2) Climate Communication. A comprehensive site covering the science, current info., action steps, etc. related to climate change. Concise and well-researched.
With the enormous amounts of information about climate change, it's useful to identify a couple of sources that provide accessible, clear information.
