Glossary Term: Global Warming

1. The Intergovernmental Panel on Climate Change (IPCC) defines Global Warming as: “The estimated increase in global mean surface temperature (GMST) averaged over a 30-year period, or the 30-year period centered on a particular year or decade, expressed relative to pre-industrial levels unless otherwise specified. For 30-year periods that span past and future years, the current multi-decadal warming trend is assumed to continue.”
2. NASA (National Aeronautics and Space Administration in the U.S.A.) defines Global Warming as: “The unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.”
