Peterson, T.M. Outside the clearly ENSO-affected regions, the large-scale patterns, e.g., over the subtropics of the Pacific and the Atlantic stay roughly the same during the year, perhaps indicating longer-term effects. Part I: Upgrades and Intercomparisons. Global warming is the unusually rapid increase in Earths average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Climate. Asia's trend during the 1910–2020 period was +0.17°C (+0.31°F) per decade; however, the 1981–2020 trend is twice the longer-term trend (+0.37°C / +0.67°F). The world’s best scientists tell us that to undo the most extreme scenarios of climate change, 2020 must be the year for coordinated, comprehensive climate action. To understand what this means for humanity, it is necessary to understand what global warming is, how scientists know it's happening, and how they predict future climate. NASA’s Global Climate Change website hosts an extensive collection of global warming resources for media, educators, weathercasters and public speakers. The ocean heating is irrefutable and a key measure of the Earth's energy imbalance: the excess greenhouse gases in the air trap more heat inside the climate system and drives global warming.
