Scientists have warned that global temperatures could rise by six degrees Celsius by the end of the century, four degrees higher than previously predicted and at a level that could wipe out species and cause widespread natural disasters.
In addition, the study by the Global Carbon Project (GCP) said on Wednesday, that the ability of the world’s forests and oceans to absorb carbon emissions was declining.
The paper, published in the journal Nature Geoscience, comes in the run up to UN talks in Copenhagen, Denmark, aimed at crafting a pact to combat climate change from 2013.
It said pollution “continued to track the average of the most carbon-intensive family of scenarios” put forward by the UN’s Intergovernmental Panel on Climate Change (IPCC).
Extreme scenario
Professor Corinne Le Quéré, the lead author of the study from the British Antarctic Survey, said: “The projections of climate that have been made before are always based on scenarios of climate change, so they tell that if the emissions are such and such you get 2C, if they are such and such you get six or seven.
“What our study is doing is identifying that the trend in the CO2 emissions, particularly from fossil fuels in the past decades, is so large it is at the higher end of the emissions scenario and this is why I am saying that we are on the scenario for a 6C warming,” she told Al Jazeera.
