Carbon dioxide is not to blame

Carbon dioxide is not to blameTemperature of the planet may be less sensitive to changes in levels of carbon dioxide (CO?), Than previously thought. These findings came a group of scientists, who published his findings in the journal Science.
According to the researchers, people still expect "radical changes" in climate worldwide, but the risk of changes slightly less serious.
Previous climate models to assess the sensitivity of climate to increased CO? were based on meteorological changes over the past 150 years. Of these models are hard to predict with certainty a single figure. The new analysis, which includes the paleoclimatic data in an existing model — is an attempt to project future temperatures with a little more confidence.
Lead author Andreas Shmittner (Andreas Schmittner) from the University of Oregon (Oregon State University), USA, explained that by studying the temperature of the last glacial period (about 21,000 years ago), when people were not able to influence the global temperature, he and his colleagues made concluded that at that time it was not as cold as previously thought. This means that the effect of CO? the climate is less than expected.
Including this newly discovered "climate insensitivity" into their models, the team was able to reduce the uncertainty in predictions of future climate. New models suggest that with the doubling of CO2 from pre-industrial surface temperature will rise by 1,7-2,6 ° C. It is much more clear the range, than those offered by the Intergovernmental Panel on Climate Change (IPCC) in its report for 2007, when they were voiced by a range of 2 ° C to 4,5 ° C. The new analysis also reduces the expected average temperature of the Earth from 3 ° C to 2 ° C.
The authors emphasize that the results do not supersede earlier findings of human influence on climate change. All threats to climate change should be considered seriously. However, to cause large-scale warming of the planet, which would have disastrous consequences, we would increase emissions of CO?.
Indeed, global carbon dioxide emissions in 2010 rose sharply. It is estimated that in 2010 the growth of emissions by 6%, which is worse than most
