Global temperatures are expected to go up four degrees Celsius when 2100 rolls around.
Scientists then predict another increase over eight degrees Celsius in 2200 according to information in the science journal Nature TG Daily reported Thursday.
"Our research has shown climate models indicating a low temperature response to a doubling of carbon dioxide from preindustrial times are not reproducing the correct processes that lead to cloud formation," Steven Sherwood, a professor from the University of New South Wales' Centre of Excellence for Climate System Science told TG Daily.
The findings give scientists answers to climate sensitivity or how warm the earth's atmosphere become, what position cloud formation plays, and how global warming will be impacted TG Daily reported.
"When the processes are correct in the climate models the level of climate sensitivity is far higher. Previously, estimates of the sensitivity of global temperature to a doubling of carbon dioxide ranged from 1.5°C to 5°C. This new research takes away the lower end of climate sensitivity estimates, meaning that global average temperatures will increase by 3°C to 5°C with a doubling of carbon dioxide," Sherwood told TG Daily.
"Climate skeptics like to criticize climate models for getting things wrong, and we are the first to admit they are not perfect, but what we are finding is that the mistakes are being made by those models which predict less warming, not those that predict more," Sherwood told TG Daily. "Rises in global average temperatures of this magnitude will have profound impacts on the world and the economies of many countries if we don't urgently start to curb our emissions."
Scientists used computer models to make sure clouds in computer climate models they were using were the same as the ones in the real sky The Guardian reported.
Scientists also calculated how the Earth's atmosphere compared to greenhouse gases via predictions about how much temperatures would increase when twice as much carbon dioxide was in the atmosphere when likened to elements before industrial times.
