A new study on global warming reveals how significant 2 C could be. The consequences are also uncovered.
Global soils comprise two to three times more carbon than the atmosphere. Higher temperatures hasten up decomposition, lowering the amount of time carbon spends in the ground, dubbed “soil carbon turnover.”
Researchers found that global warming of 2 C would drive to approximately 230 billion tons of carbon being discharged from the soil.
Here is what you need to know.
Global Warming Where To
The University of Exeter led the new study. Researchers offer the latest status of global warming.
According to the study, the estimated 230 billion tons of carbon discharged at 2 C warming (over the pre-industrial levels) is actually more than four times the total emissions from China, and double the emissions from the US, over the last century.
Researchers named the effect: the positive feedback. Such a thing means that climate change causes some knock-on forces that influence further climate change. Dr.Sarah Chadburn is the co-author of the study. She released a statement:
“[the study], suggests substantial soil carbon losses due to climate change at only 2 C warming, and this doesn’t even include losses of deeper permafrost carbon.”
And what is the response of soil carbon to climate change?
Unfortunately, that is massive uncertainty in comprehending the carbon cycle in climate change predictions. The researchers, however, did try their best.
The Team’s Work
Researchers utilized a novel mix of Earth System Models and observational data – it simulates the carbon cycle and the climate and subsequently offers climate change projections.
Furthermore, the team examined how soil carbon is related to temperature in various regions on Earth to find out its sensitivity to global warming. Also, state-of-the-art models indicate uncertainty of approximately 120 billion tons of carbon at 2 C global mean warming.
The recent study lowers that uncertainty to around 50 billion tons of carbon.
