Though I will not blame it on human consumption induced climate change or global warming, the ominous signs of the nature cycle shift is in the air. No, I am not talking of the cataclysmic rainfall followed by floods in Queensland and Northern Australia early this year or the snow storms that raged across Europe and the northern hemisphere from North America to China . I am in fact talking of the depleting Amazon rain forests due to the droughts of 2005 and 2010 that have killed billions of trees over thousands of acres along the parched tributaries of the giant river. Here below and above are some telling pictures of how it looks now that one of the biggest tributary Rio Negro has turned into a dried out river bed and the forests have turned into grasslands
The dried out river banks which are miles wide at most places and stretch for hundreds of miles after the 2010 drought.
Acres of rain forests have disappeared and have been replaced by grasslands in the Amazon
Brazil's Rio Negro is a major tributary of the Amazon and a home to an ecosystem that supports millions of plant and animal species. The 2005 and 2010 droughts dried out parts of the river and killed billions of trees
Researcher Simon Lewis in Science magazine wrote that according to a few models the quick and successive droughts in the Amazon basis is a freak phenomenon and could be due to changes in the temperature level in the Atlantic that has occurred due to man made warming.
Researchers also say that the drought and the death of billions of trees within months would not only affect the capability of a large part of the Amazonian rain forest to act like a carbon sink, but that it could eventually become a carbon source leading to increased global emissions. Applying the techniques of extrapolation researches feel that the mass destruction of trees due to the two drought could have added 8 billion tonnes of carbon to the atmosphere and thus caused further global warming that could bring about greater and more severe droughts in the future
