Amazon Rainforest Now More Susceptible to Die Out

Amazon Now More Susceptible to Die Out as its dry season is now three weeks longer  than 30 years ago says a new study, reports Katie Valentine at Climate Progress. The study found the increase in dry days makes the southern portion of the Amazon rainforest more susceptible to dieback, both from lack of rain and from increased risk of forest fires, which are more likely to occur in the rainforest when humidity is low. The lead study author noted that, “If the dry season is too long, the rainforest will not survive.”  If the Amazon begins to die out, large amounts of carbon dioxide stored in the trees and plants there will be released into the atmosphere, further exacerbating climate change.  The dry season is the most important factor controlling that ecosystem, which, if it did dry out, would release gargantuan amounts of greenhouse gases to the atmosphere, further accelerating warming and climate change.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
