Climate change caused by mankind will release extra heat-trapping gases stored in nature into the atmosphere, a study has shown.

 

But the knock-on effect of the additional carbon dioxide — stored in soils, plants and the oceans — on top of industrial emissions building up in the atmosphere will be less severe than suggested by some recent studies, they said.

 

The data, based on natural swings in temperatures from 1050-1800, indicated that a rise of one degree Celsius would increase carbon dioxide concentrations by about 7.7 parts per million in the atmosphere.

 

The good news: That is far below recent estimates of 40 ppm, which would be a much stronger boost to feared climate changes such as floods, desertification, wildfires, rising sea levels and more powerful storms, they said.
