ALMOST AS IF SPECIES ADAPT...:

New Study Supports Evidence That CO2 is Actually Making Forests More Resilient (Michael Bastasch, 1/19/16, Stream)

A new study supports evidence that rising levels of carbon dioxide emissions are making American forests healthier and more resilient. In fact, U.S. forests are likely to get even healthier over the next few decades.

"We found that trees are tolerant of rising temperatures and have responded to rising carbon dioxide," according to a recent study by scientists with the National Council for Air and Stream Improvement and the Center for the Study of Carbon Dioxide and Global Change.

Scientists reviewed a slew of studies to see what scientists found in regards to how global warming would impact forest health. While there seems to be disagreement over the future of forest health in a warmer world, scientists found "United States forest health has improved over recent decades and is not likely to be impaired in at least the next few decades."

"We find that plants can shift their optimum temperature for photosynthesis, especially in the presence of elevated CO2 , which also increases plant productivity," scientists wrote. "Additionally, elevated CO2 increases water use efficiency and protects plants from drought."
