Global Warming

The Intergovernmental Panel on Climate Change released a report on global warming yesterday. This report, the Summary for Policymakers of the first volume of “Climate Change 2007”, addresses the natural and human drivers of climate change and states that:

"Global atmospheric concentrations of carbon dioxide, methane and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values determined from ice cores spanning many thousands of years. The global increases in carbon dioxide concentration are due primarily to fossil fuel use and land-use change, while those of methane and nitrous oxide are primarily due to agriculture."
