'''''US Forests nationwide feeling the heat from drought and climate change'''''


"Over the last two decades, warming temperatures and variable precipitation have increased the severity of forest droughts across much of the continental United States," said James Clark, lead author of the 14 institution study.
According to Global Change Biology, "Virtually all U.S. forests are now experiencing change and are vulnerable to future declines..."  


Clark and colleagues published their paper today in the journal Global Change Biology.

Forests and woodlands cover about 20% of Earth's land surface, spanning all but the highest latitudes. In the millennia since humans dispersed across all forested continents, we have transformed large areas of natural forest. Historically, our greatest impacts were made in temperate regions, but they now extend to forests in the tropics and the boreal zone. Only a fraction of the forests present centuries ago have escaped human influence; in many regions the forest is gone, has regrown as secondary forest, or consists of managed and plantation forests. Humans have also introduced new species, including pests and pathogens of trees. Other influences — such as climate warming that causes tree species to shift geographically and anthropogenic drought that causes forest dieback — take effect more slowly...

● Forests: Sinks or Sources?

Tropical forests now emit more carbon than they are able to absorb from the atmosphere as a result of the dual effects of deforestation and land degradation, a new study says.

The research challenges the long-held belief that forests act as “carbon sinks” by storing more carbon than they emit due to natural processes and human activity.

The Bonn Challenge is a global effort to restore 150 million hectares of the world's deforested and degraded lands by 2020 and 350 million hectares by 2030.

August 2017
