Amazon rainforest losing capacity fight climate change as trees die

Independent: The Amazon rainforest is losing its ability to absorb carbon dioxide in the atmosphere as trees are dying, which could have negative implication on climate change across the globe. A study led by the University of Leeds revealed that tree growth in the Amazon rainforest has declined by one-third since the 1980s and that the net uptake of carbon dioxide in the rainforest has dropped by half. For the first time in history, carbon dioxide absorption by the Amazon rainforest has been surpassed...

Amazon rainforest soaking up less carbon as trees die young

Reuters: The Amazon rainforest's ability to soak up greenhouse gases from the air has fallen sharply, possibly because climate change and droughts mean more trees are dying, an international team of scientists said on Wednesday. The world's biggest rainforest has soaked up vast amounts of carbon dioxide. Plants use the heat-trapping gas to grow and release it when they rot or burn, but the report said that role in offsetting global warming may be under threat. The study, of 321 plots in parts of the Amazon...

In warmer climate, a bid to preserve trees threatened by emerald ash borer

MPR: In Minnesota, infestations have been found in the Twin Cities and in the state's southeastern corner. In northern Minnesota, where there are more than one million acres of black ash forest containing nearly a billion trees, researchers say the threat is made worse by a changing climate. Research suggests the pest is only kept at bay when temperatures dive 30 below zero. "We're likely to have less and less winters reaching that extreme cold temperature," U.S. Forest Service researcher Brian...
