Climatologist José Marengo shows concern for increase in extreme flooding and changes in the hydrology of the Amazon region.
The west, the northwest and part of the central area of the Brazilian Amazon face extreme flood events in the last three years caused by above the average rainfall.
Researcher warns of the factors that may have influenced the current drop in rainfall patterns in Southeast Brazil, as the destruction of the Amazon rainforest and global warming, and requires change in the position of Brazil in relation to environmental issues .
The forest that remains is receiving less rain, which in turn is making it less green which means the trees that are there are pulling in less carbon dioxide from the air around them.
The rainforest will become a source of carbon dioxide if climate change continues and extremes in precipitation, according to a study published in the British journal Nature.
The seasonality of sunlight and rainfall regulates net primary production in tropical forests. Previous studies have suggested that light is more limiting than water for tropical forest productivity.
Among the areas affected by the floods in the country there are zones that are cut by rivers in the middle of the Amazon. Due to the floods, 44 dead.
A study led by NASA scientist Doug Morton finds that earlier research concluding that photosynthesis increases in the Amazon during the dry season is based on faulty interpretation of satellite imagery.
Peruvian government declared a state of emergency yesterday in various districts of the provinces of Tambopata, Manu and Tahuamanu, to perform immediate and necessary measures against the damage caused by the rains.
Carbon balance of the largest tropical forest on Earth depends on rainfall, says an article in ‘Nature’. In the same issue, new interpretations of satellite imagery explain ‘greening’ of the forest during the dry season.
