I got my M.S. in earth science at Dartmouth 21 years ago. I co-taught several classes in environmental science. Over two decades later, many of the disasters we knew were coming have happened and still nothing has been done do stem the tide. Now I'm a mother and my oldest is headed to college. I'm doing everything in my power to preserve a livable climate for her and my other kids. The science is clear; the time to #ActOnClimate is NOW.
