Meteorological satellites used by NASA within the scope of the Clouds and Earth’s Radiant Energy System (CERES) project have detected a significant increase in the amount of solar energy absorbed by the planet in the last 10 years. This, It was far beyond the warming caused by the increase in greenhouse gases.
By examining CERES data, it was determined that the Earth reflects less light coming to it. Researchers say this could be due to reduced air pollution, as air pollutants reflect light back into space.
In the study published in the scientific journal Communications Earth & Environment Clean air may be responsible for 40 percent of the energy increase that caused the planet to warm in the period 2001-2019. found.
While climate experts have long expected that the decrease in pollution could lead to warming, the decrease in particles called aerosols reached a point that was noticed globally two years ago.
On the other hand, the only explanation for the brighter sky may not be the decrease in pollution. CERES data show that Earth’s ability to reflect light has decreased in both hemispheres, but pollution has decreased more in the Northern Hemisphere. Additionally, the models in the new research do not offer an explanation for up to 40 percent of the extra absorbed light.
Scientists examining China’s long-term efforts to reduce air pollution also draw attention to the increase in warming. According to official data of the Asian country, it is mainly from coal power plants. emitted sulfur dioxide (SO2) with these efforts to eliminate the pollution caused by SO2 emissions decreased by nearly 90 percent.
However, average temperatures in China, which has lost its toxic shield, have increased by 0.7 degrees since 2014. Scientists say eliminating air pollution may have had a bigger impact on temperatures in some Chinese cities over the past decade than warming from greenhouse gases.
But despite its impact on global warming, climatologists do not recommend ending the fight against air pollution. Instead, experts emphasize that more effective steps should be taken to reduce greenhouse gas emissions and state that one of the most promising ways in the short term to compensate for the effects of the weather becoming clearer is to reduce methane gas.
