Lead author Andreas Schmittner from Oregon State University, US, explained that by looking at surface temperatures during the most recent ice age – 21,000 years ago – when humans were having no impact on global temperatures, he, and his colleagues show that this period was not as cold as previous estimates suggest.
The new models predict that given a doubling in CO2 levels from pre-industrial levels, the Earth’s surface temperatures will rise by 1.7C to 2.6C (3.1F to 4.7F).
That is a much tighter range than the one produced by the Intergovernmental Panel on Climate Change’s (IPCC) 2007 report, which suggested a rise of between 2.0C to 4.5C.
The new analysis also reduces the expected rise in average surface temperatures to just over 2C, from 3C
