The most alarming forecasts of natural systems amplifying the human-induced greenhouse effect may be too high, according to a new report.
The study in Nature confirms that as the planet warms, oceans and forests will absorb proportionally less CO2.
It says this will increase the effects of man-made warming – but much less than recent research has suggested.
The authors warn, though, that their research will not reduce projections of future temperature rises.
Further, they say their concern about man-made climate change remains high.
The research, from a team of scientists in Switzerland and Germany, attempts to settle one of the great debates in climate science about exactly how the Earth’s natural carbon cycle will exacerbate any man-made warming.
