Amazon Droughts shock Scientists

According to an article which was posted to the Physorg.com  website, scientists are shocked to have learned that the drought which afflicted the Amazon region during the year 2010 was more devastating than the drought which hit the region in the year 2005. The article which you can read at:

http://www.physorg.com/news/2011-02-severe-amazon-droughts-years-alarms.html

states the following:


"Two unusual and extreme droughts occurring within a decade may largely offset the carbon absorbed by intact Amazon forests during that time. If events like this happen more often, the Amazon rainforest would reach a point where it shifts from being a valuable carbon sink slowing climate change, to a... major source of greenhouse gasses that could speed it up."!!

This certainly is disturbing news!!  As stated in the article: "The unusual drought, affecting south-western Amazonia, was described by scientists at the time as a 'one-in-100-year event' (2), but just five years later the region was struck by a similar extreme drought that caused the Rio Negro tributary of the Amazon river to fall to its lowest level on record."

"Amazon forests will not absorb their usual 1.5 billion tonnes of CO2 from the atmosphere in both 2010 and 2011, and that a further 5 billion tonnes of CO2 will be released to the atmosphere over the coming years once the trees that are killed by the new drought rot!!"

"Considerable uncertainty remains surrounding the impacts of climate change on the Amazon. This new research adds to a body of evidence suggesting that severe droughts will become more frequent leading to important consequences for Amazonian forests. "

Of course the big question these scientists must be trying to answer is: Why are these droughts are occurring in the region?


In an article entitled, "Amazon Drought Worst in 100 Years" written on October 24th,2005 at the 
http://www.ens-newswire.com/ens/oct2005/2005-10-24-05.asp  website, it is stated:






"The drought is caused by three factors, ... the warming of the Atlantic Ocean, reduction in arboreal transpiration, and the smoke emitted by forest burnings.""The chief reason is the warming of the Northern Tropical Ocean, which is up to two degrees warmer than average," he said.
  

Clearly this new drought suggests that these three factors still are in existence in the region  and have caused this latest drought to occur. The warming of the Northern Tropical Ocean must apparently still occurring, which also causes one to wonder what is happening to the life in this ocean because of this increase in temperature of the water?

"Greenpeace say the droughts and resulting deforestation have grave consequences."        

  "Marcio Astrini, Green Peace Amazon Campaign Coordinator]:
"It leads to land grabbing, evasion of borders, destruction of natural resources, and also brings consequences of global warming because of the emission of gases that cause the world's temperatures to rise and which will make these natural disasters more intense and more frequent harming the populations of these areas as well as the entire planet."         
   
  "Some scientists say severe droughts—which kill trees and make them more vulnerable to fires—are part of a damaging cycle that is bringing the Amazon closer to a "tipping point," at which its destruction becomes self sustaining."

"The warming of the atmosphere caused by increases in greenhouse gases is melting glaciers and causing ocean water to warm and expand thermally. Both effects increase the volume of the ocean, raising its surface level."

We all need to change our behavior if these massive and profound effects of global warming (such as the droughts in the Amazon) are to be curtailed!

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed



Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia



A person's true wealth is the good he or she does in the world. - Mohammed



Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein



The best way to find yourself, is to lose yourself in the service of others. - Ghandi



The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller



Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns



Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama



Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -



Milan Kundera, The Unbearable Lightness of Being



The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
