“Energy imbalance” refers to the difference between how much of the Sun’s “radiative energy” is absorbed by Earth’s atmosphere and surface, compared to how much “thermal infrared radiation” bounces back into space. “A positive energy imbalance means the Earth system is gaining energy, causing the planet to heat up,” Nasa said
Scientists from Nasa, the US space agency, and the National Oceanic and Atmospheric Administration (Noaa), reported in a new study that Earth’s “energy imbalance approximately doubled” from 2005 to 2019. The increase was described as “alarming”. The Earth is trapping nearly twice as much heat as it did in 2005, according to new research, described as an “unprecedented” increase amid the climate crisis.
The study found that this doubling is the result, in part, by an increase in greenhouse gases and water vapor, as well as decreases in clouds and ice.
Unless the rate of heat uptake slows, greater shifts in climate should be expected.
