Most of the alarmism generated by climate predictions deals with sea level rise, drought, and biodiversity loss. But what happens to waterfront property, farms and polar bears could be the least of our worries if temperatures rise much more than a few degrees. A new paper in PNAS, “An adaptability limit to climate change due to heat stress,” paints a much more dire future for much of the larger mammals on the planet, including humans.
There’s a letter in today’s Science from 255 members of the National Academy of Sciences that deserves to be read:
