The Amazon forest is greener when the sun is drought!

This phenomenon almost goes against the natural law. Drought makes the Amazon rainforest, located between 9 South American countries getting more and more green - according to research results of the University of Arizona (USA). This means that the effects of global warming on the South American ecosystem may not be as fierce as previously predicted.

Many global climate models predict rising Earth temperatures will cause severe drought in the Amazon basin, and may lead to the end of the forest where there will be only a few trees left. Often, when it comes to drought, the plant will react by limiting both processes: evapotranspiration and photosynthesis. This reaction made the drought worse because the amount of water drained into the atmosphere decreased, resulting in limited rainfall.

But watching through photos from satellite leaves and chlorophyll content - two indicators of forest greenness - during the large-scale drought affected the Amazon forest in 2005, researchers It was found that the green color of forest trees was really darker. This phenomenon may be caused by plants absorbing more sunlight while the roots grow deeper into the soil to find water.
