- The National Research Council has released a new booklet and video designed to help the public gain a better understanding of what is known about climate change. The new resources are based on a number of independent reports from the National Research Council that represent the consensus of experts who have reviewed hundreds of studies describing many years of accumulating evidence.
The 36 page booklet, entitled Climate Change: Evidence, Impacts, and Choices answers commonly asked questions about the science of climate change in three parts. The booklet lays out the evidence of climate change being observed around the world, summarizes projections of future climate changes and impacts expected in this century and beyond, and examines how science can help inform choices about managing and reducing the risks posed by climate change.
The video, Climate Change: Lines of Evidence, follows Part 1 of the booklet. It explains the lines of evidence that have built the current scientific consensus about climate change and its causes.
