The Amazon Rainforest and Climate Change By Arash Hozhabri"The ecosystem’s response is lagging behind the rate of climate change" (Muelbert, 2018).Research done by the University of Leeds shows that over the past 30 years, higher c02 levels, high temps, and droughts have increased the mortality rates of thousands of tree species. Also, the trees that are more vulnerable to droughts are not being replaced fast enough by the trees that can thrive in dry environment.
This slow decline affects the overall tree diversity in the rain forest. Univ er sity of Texas at Aust in Geoscience. (2008, O ctober 23). Summer Rain: Ker r y Cook's Climat e Resear ch in Afr ica and t he Am er i ca. Ret r iev ed Nov ember 11, 2018, fr om ht t ps://www.jsg.utexas.
edu/news/2008/10/summer -r ain/Good News Pioneer trees (trees that grow in abundance after old trees die off) benefit from the increase in C02 levels. These trees will grow faster due to the high levels. They also disperseAlso, the number of pioneer trees and the rate of climate change are increasing similarly, so these trees can help slow down the overall decrease in biodiversity.
Example of Cecropia (pioneer spec ies )For some more bad news Scientists say that by year 2050, not only will the average temperture go up 3 degrees (celcius), but droughts will be dryer because of even less rainfall during dry months (Nepstad, 2008).Citations Background.
