A study conducted by scientists at NASA has found that “Earth’s energy imbalance approximately doubled” in just 14 years from 2005 to 2019. The findings of the study were published in the Geophysical Research Letters.
NASA explained that this planet’s climate is dictated by the balance between the amount of the absorbed sun’s energy and the emitted thermal infrared radiation.
“Continued increases in concentrations of well-mixed greenhouse gasses in the atmosphere and the long time-scales time required for the ocean, cryosphere, and land to come to thermal equilibrium with those increases result in a net gain of energy, hence warming, on Earth,” the study’s summary explains.
It was also found that a shift of Pacific Decadal Oscillation (PDO) from a cool phase to a warm phase possibly contribute to the intensification of the imbalance.
“It’s likely a mix of anthropogenic forcing and internal variability,” said Norman Loeb, lead author for the study and principal investigator for CERES at NASA’s Langley Research Center in Hampton, Virginia, in a news release by NASA.
