Warming of the earth's atmosphere has been a topic of debate for a long time. Is it natural or anthropogenic? Scientists think that there may be a correlation between vegetation and earth’s temperature.
During the initial years of the holocene era- the current geological epoch temperature was relatively cool and then after grasslands grew, it increased the temperature by almost 1.5 degree celsius, which is confusing scientists. Previous models were made to study Earth's atmospheric temperatures since the last ice age indicate that the temperature has been rising constantly, some studies show it peaked around 6000 to 9000 years ago.
“Expanded vegetation during the Holocene warmed the globe by as much as 1.5 degrees Fahrenheit, our new simulations align closely with paleoclimate proxies. So this is exciting that we can point to Northern Hemisphere vegetation as one potential factor that allows us to resolve the controversial Holocene temperature conundrum." said Alexander Thompson, a postdoctoral research associate in earth and planetary sciences in Arts & Sciences.
