A few years ago in a lab in Panama, Klaus Winter tried to conjure the future. A plant physiologist at the Smithsonian Tropical Research Institute, he planted seedlings of 10 tropical tree species in small, geodesic greenhouses. Some he allowed to grow in the kind of environment they were used to out in the forest, around 79 degrees F. Others, he subjected to uncomfortably high temperatures. Still others, unbearably high temperatures — up to a daily average temperature of 95 F and a peak of 102 F. That’s about as hot as Earth has ever been.
It’s also the kind of environment tropical trees have a good chance of living in by the end of this century, thanks to climate change. Winter wanted to see how they would do.
The answer came as a surprise to those accustomed to dire warnings that climate change will turn the Amazon into a desert. The vast majority of Winter’s seedlings didn’t die. In fact, most thrived at significantly warmer temperatures than they experience today, growing faster and larger. Just two species succumbed to the heat, and only ... Read more
