Frequently, when we post articles and essays about climate change, we get comments expressing some doubts about the reality of global warming. While some would refuse to accept any evidence offered, many of these commenters seem honest in their protestations that they haven't seen the evidence all put together in a way that makes sense. I haven't had a good pointer for them -- combining serious science, mainstream sources, and compelling presentation -- until now.
The Marain Koshland Science Museum of the National Academy of Sciences is a new Washington DC landmark, having just opened in April. Its focus is on the science underpinning current public policy debates, and its exhibits will remain on display for two years before touring around the country. (If you're unfamiliar with the National Academy of Sciences, it is a non-profit organization given a mandate by Congress in 1863 to provide high-quality, non-partisan advice to the federal government. Yes, 1863.)
One of the three exhibits at the KSM is "Global Warming Facts and Our Future," and the online version is one of the best presentations of the science surrounding global warming-induced climate change I've ever seen. The online exhibit -- a mix of HTML and Flash -- lays out the argument for global warming in a straightforward but compelling way. Each phase is well-illustrated and detailed:
Note in particular the page discussing human activities as the major cause of global warming. The presentation includes exercises where visitors can make policy choices, and see the balancing required between economic and environmental concerns. One of the best aspects of the presentation is that it doesn't try to brush points of scientific dispute under the rug; it details how major models disagree on certain points, and what that means.
I doubt this exhibit will change the minds of those who are in denial, but if you -- or someone you know -- has questions about global warming, how it works, how we know what we know, and what we can do about it, this is a good place to start.
