2C rise by 2100: IPCC

Human influence has been the dominant cause of global warming since the mid-20th century and is expected to lead to a rise in surface temperature exceeding 2 degrees Celsius by the end of the century.

These are the findings of the Intergovernmental Panel on Climate Change (IPCC), which released its Fifth Assessment Report (AR-5) in Stockholm on Friday. The report says the world is on track for more than 2 degrees and possibly more than 4 degrees warming by 2100.

Emphasising that the average surface temperatures were up 0.85 degrees since 1880, the report said that it is extremely likely with 95% certainty that humans are the dominant cause global of warming. The report revealed that the evidence for human influence in climate change has grown in the last five years.

IPCC's fourth assessment report (AR-4) came out in 2007, which said that for global temperature to stabilise at 2-2.4 degree Celsius above the pre-industrial average, emissions would need to peak before 2015, with 50-85% reductions from the 2000 levels by 2050.
