As it turned out, you can learn a lot of new and interesting things about the climate of our planet by simply observing the lunar eclipses. Richard Keene, an American climatologist at the University of Colorado, spent several decades studying eclipses of the Earth’s satellite, and is now ready to present the results of voluminous work.
According to the expert, if we take into account the color and brightness of the eclipses that have occurred in recent years, we can say with confidence that the stratosphere of the Earth is quite clean, since it contains an insignificant amount of volcanic aerosols. This indicates that the Earth's stratosphere passes sun rays well, and this contributes to a better warming of the planets below.
To clearly understand the effect of volcanic aerosols on lunar eclipses, Keen performed a comparative analysis of two eclipses that occurred in different years and under different conditions. The first option presented by the scientist is the lunar eclipse of 1992, which took place after the grandiose eruption of Pinatubo volcano (Philippines), as a result of which the atmosphere was polluted by millions of tons of dust and gas. Since 1995, the stratosphere has been clean, which has contributed to a 0.6 W increase in solar radiation per square meter. In simple terms, the heating increased by 0.1-0.2 degrees. The second option was an eclipse that occurred at the beginning of this year.
Hence the conclusion: a decrease in the content of aerosol particles and an increase in greenhouse gas emissions have contributed to the general warming on the planet.
As you know, lunar eclipses occur once or twice a year. In January, earthlings already enjoyed this spectacle, and the next heavenly performance will take place on July 27, which Richard Keane is waiting for. The fact is that this eclipse will be the longest in the last century – 1 hour and 43 minutes. During this time, experts will have time to analyze the color and brightness of the earth’s shadow in order to determine the aerosol concentration in the stratosphere.
