"Science journalist Michael Lemonick doesn't want to be a doomsday prophet, but he does want to be realistic about the threat of climate change. 'Since I started writing about climate change all the way back in 1987, we've known what the cause is, we've known what the likely outcome is, and we've had time to act — and essentially we haven't acted,' he tells Fresh Air's Dave Davies.
Lemonick is the co-author of a new book, Global Weirdness: Severe Storms, Deadly Heat Waves, Relentless Drought, Rising Seas, and the Weather of the Future. The book, published by the nonprofit research organization Climate Central, details the effects of climate change and greenhouse gases in ocean acidity, existing ecosystems, disruptions to food supply and rising sea levels. Lemonick says sea level has risen by about eight inches overall worldwide since around 1900, and the waters are expected to rise an estimated three feet by 2100."
