With Deaths of Forests, a Loss of Key Climate Protectors http://apocadocs.com/s.pl?1317666846
From the mountainous Southwest deep into Texas, wildfires raced across parched landscapes this summer, burning millions more acres. In Colorado, at least 15 percent of that state's spectacular aspen forests have gone into decline because of a lack of water.
The devastation extends worldwide. The great euphorbia trees of southern Africa are succumbing to heat and water stress. So are the Atlas cedars of northern Algeria. Fires fed by hot, dry weather are killing enormous stretches of Siberian forest. Eucalyptus trees are succumbing on a large scale to a heat blast in Australia, and the Amazon recently suffered two "once a century" droughts just five years apart, killing many large trees.
Experts are scrambling to understand the situation, and to predict how serious it may become....
Scientists have figured out -- with the precise numbers deduced only recently -- that forests have been absorbing more than a quarter of the carbon dioxide that people are putting into the air by burning fossil fuels and other activities. It is an amount so large that trees are effectively absorbing the emissions from all the world's cars and trucks.
