Joint NASA, NOAA Study Finds Earth’s ‘Energy Imbalance’ Has Doubled, Heating Up Planet; ‘The Trends We Found Were Quite Alarming’

Earth's climate is determined by a delicate balance between how much of the Sun's radiative energy is absorbed in the atmosphere and at the surface and how much thermal infrared radiation Earth emits to space. A positive energy imbalance means the Earth system is gaining energy, causing the planet to heat up. Now, NOAA and NASA researchers have found that Earth’s energy imbalance approximately doubled during the 14-year period from 2005 to 2019.
