Earth is storing more ‘unprecedented’ heat

Between 2005 and 2019, the so-called energy imbalance on Earth nearly doubled, researchers from NOAA and NASA said in the journal Geophysical Research Letters. This trend is primarily due to increased solar radiation absorbed due to reduced reflectivity from clouds and sea ice. At the same time, long-wave radiation from Earth to space, through which energy and, accordingly, heat are released, has decreased due to an increase in greenhouse gases in the atmosphere.

It is based on a sensitive energetic balance on the Earth: on the one hand, the Earth’s atmosphere and surface absorb the sun’s rays, and on the other hand, the Earth emits infrared rays into space. If both processes are in balance, then the energy balance is balanced. A positive energy balance means that the Earth is warming. As the oceans absorb about 90 percent of this excess energy, the waters in the seas are warming.
