Warmer Antarctica Shows Climate Changing on Every Continent
Humanity's impact on climate has been detected on every continent except Antarctica, or so said the United Nations Intergovernmental Panel on Climate Change (IPCC) in February 2007. No longer: scientists, comparing decades of records from 17 Antarctic weather stations with computer simulations of Earth's climate, found that human-induced global warming has been heating up the continent that is home to the South Pole, as well.
"We have detected the human fingerprint in both the Arctic and Antarctic region[s]," says Peter Stott, a climate modeler at the U.K. Met (meteorological) Office's Hadley Center, and co-author of the study published in the journal Nature Geoscience.
The researchers compared 100 years of weather records from the Arctic and 50-plus years of those kept on Antarctica with the results of four computer models. Their findings: natural influences such as changes in the amount of sunlight or volcanic eruptions did not explain the warming trends, but the results matched when increasing levels of greenhouse gas emissions were added to the mix.
