Many Overheated Forests May Soon Release More Carbon Than They Absorb

New research suggests that, sooner than expected, trees may become carbon sources rather than carbon sinks, as a feedback loop of rising temperatures drives them to release more greenhouse gases.

The last decades have been filled with dire warning signs from forests. Global warming has contributed to thinning canopies in European forests and to sudden die-offs of aspen trees in Colorado, as well as insect outbreaks that are killing trees around the world. In many places, forests are not growing back.

New research shows that Earth’s overheated climate will alter forests at a global scale even more fundamentally, by flipping a critical greenhouse gas switch in the next few decades. The study suggests that, by 2040, forests will take up only half as much carbon dioxide from the atmosphere as they do now, if global temperatures keep rising at the present pace.

Friggin fools.

How you get rid of beetle kill is logging.
How you get rid of undercanopy and laddering is logging.
How you stop a quarter million acres a year just in Montana from going up in smoke (carbon release) IS FRIGGIN LOGGING.

So are they claiming Nuclear Fusion or Fission?

Carbon is an element.  "Making it" requires one or the other.

What about global greening?

Make no mistake, they will now come after anything disputing man-made global warming, the same way they did anything disputing the election.  They will start cancelling your Twitter accounts and all that.
