Science: Global warming is killing U.S. trees, a dangerous carbon-cycle feedback

... decades , with doubling periods ranging from 17 to 29 years among regions. After examining a variety of potential causes, the study concludes: Regional warming and consequent increases in water deficits are likely contributors to the increases in tree mortality rates. And this is only the tip of the (disintegrating) iceberg — the planet is on an emissions path to warm 10 times as much in the coming century as we warmed during the period examined in this study . As a co-author warned the BBC , this is another potential major amplifying feedback that could itself accelerate ...
New study concludes global warming is killing U.S. trees, a dangerous carbon-cycle feedback

... warming caused an increased number of trees to die, there would be less living trees to absorb carbon dioxide from the atmosphere. Yet there would be an increased proportion of decaying trees, releasing the carbon that had been locked away inside the trees’ wood. The denier reaction to this study, if anyone cares, is to blame the Forest Service for containing forest fires, which they conclude has allowed "bugs" to proliferate and cause this problem. The authors cover that in a BBC article . After ruling out a variety of other possible factors, including insect attacks and air ...
