In the long term, the Earth's temperature may be 30-50 percent more sensitive to atmospheric carbon dioxide than has previously been estimated, reports a new study. The results show that components of the Earth's climate system that vary over long timescales -- such as land-ice and vegetation -- have an important effect on this temperature sensitivity, but these factors are often neglected in current climate models.
