En gruppe forskere har sammenlignet prognosene IPCC gjorde i forrige rapport i 2001 med det som faktisk har skjedd, og kommet til at klimaendringene ligger i aller øverste ende eller går enda raskere enn anslått.
Writing in the journal Science, an international group of scientists concluded that temperatures and sea levels had been rising at or above the maximum rates proposed in the last report, which was published in 2001.
The paper compared the 2001 projections on temperature and sea level change report with what has actually happened.
The models had forecasted a temperature rise between about 0.15C-0.35C (0.27-0.63F) over this period. The actual rise of 0.33C (0.59F) was very close to the top of the IPCC’s range.
