    400 ppm World, Part 2: Rising Seas Come with Rising CO2

    Every indication is that thermal expansion will not dominate rates of sea-level rise in the future. As Earth’s climate marches toward equilibration with present-day CO2 levels, the climate will continue to warm. And this warming threatens the stability of a potentially much, much larger source for sea-level rise — the world’s remaining ice sheets.

    What Anthropologists Can Do About Climate

    How can the full range of the social sciences be brought into research on climate change and the search for solutions? The roles of economics and political science seem crucial, since pricing mechanisms and policies are needed to promote mitigation and to support adaptation. Psychology explores the ways to make this problem, often seen as…
