Drought in the Amazon forest causes climate change

On February 9, experts from the Amazon rainforest in South America have accelerated the climate change process in the meteorological regions of the United Nations and internationally confirmed severe drought at the bridge.

Meteorological experts from the United Nations and the University of Leeds in the UK said that the Amazon forest has drastically reduced the ability to absorb CO2 from the atmosphere while millions of trees died due to drought in 2010 release their CO2. gathered from more than 300 years into the atmosphere. This greenhouse gas emissions can be up to 5 billion tons.

According to a study published in the British journal Science, two 2005 and 2010 droughts in the Amazon forest area poured into the atmosphere up to 13 billion tons of CO2, equivalent to the total amount of US and China emissions, the two countries with the largest emissions in the world, discharged into the atmosphere in 2009.

Research results of British and Brazilian scientists since 2005 also confirmed that the CO2 emissions balance in the Amazon forest has changed dramatically.

In most years, the Amazon forest absorbed 1.5 billion tons of CO2 from the atmosphere, but during and after the drought period of 2005, the Amazon forest stopped absorbing CO2 for two years and became a source of CO2 emissions up to 5. billion tons during the 4-8 year period due to millions of dead trees releasing CO2.

This phenomenon will be repeated, even more serious in the drought in 2010 because more trees die. The drought in 2010 spread over an area of ​​many millions of square kilometers.

UN and international scientists note that two large-scale droughts in 2005 and 2010 are extremely unusual but almost coincide with the forecast of the region's bad weather model. .

The study "Assessing the risk of dying Amazon forests" warned of weather changes, deforestation and forest fires, the Amazon forest will be lost 66% in the area of ​​5.3 million km2 now in 2075, This means that the Amazon forest from the size of the entire American continent shrinks to the size of Alaska.

In the past four years, rainfall has decreased by 25% in the Southeast of Amazon and caused 10,000km2 of forest fires. Smoke from the forest continues to reduce rainfall, making the forest more dry.

The Amazon forest science studies all conclude that most scientific evidence shows that climate change is accelerating while political actions to prevent it are still delayed.
