As the heat of the summer is upon us and if you are wondering if it is truly getting hotter or if this is just natural variability, yet another summary of the science reminds us that climate change is real, that it is caused largely by our emissions of CO2 and other greenhouse gases and that the risks to societies and ecosystems are significant.
The recent report by the National Academy of Sciences entitled America’s Climate Choices summarized the science on climate change and once again concluded that
A strong, credible body of scientific evidence shows that climate change is occurring, is caused largely by human activities, and poses significant risks for a broad range of human and natural systems.
The reports on America’s Climate Choices can be accessed here.
For those giving talks or writing papers on climate science, the chapters have many useful figures that can be copied and incorporated into presentations. Here are a few chapters that I’ve used:
Chapter 2–What We Know
Chapter 6-Changes in the Climate System
Chapter 7–Sea Level Rise
Chapter 9–Ecosystems and Biodiversity
Chapter 10–Agriculture and Food Production
Chapter 11–Public Health
The news is serious indeed. The technology exists for reducing our CO2 emissions. All that is needed is the continued strengthening of our resolve to move quickly.
