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.

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”.

“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 in a statement about this study.

Scientists determined there was an energy imbalance by comparing data from satellite sensors – which track how much energy enters and exits Earth’s system – and data from ocean floats.
