Solar Eclipses and the Disappearance of Cumulus Clouds: Implications for Climate Engineering Techniques

During a solar eclipse, shallow cumulus clouds over land begin to disappear when around 15% of the Sun's disc is obscured by the Moon. This occurs because Cumulus clouds feed off columns of rising air called thermals and these rising thermals are formed by the heat of the sun shining down onto the ground.
The study shows that scientists may be underestimating the amount of solar radiation reaching Earth during a total solar eclipse.
Solar Eclipses and the Disappearance of Cumulus Clouds: Implications for Climate Engineering Techniques

A recent study has shown that during a solar eclipse, shallow cumulus clouds over land begin to disappear when around 15% of the Sun's disc is obscured by the Moon. This occurs because Cumulus clouds feed off columns of rising air called thermals and these rising thermals are formed by the heat of the sun shining down onto the ground. As less solar radiation reaches Earth during a solar eclipse, fewer cumulus clouds form and those that do dissipate quickly once they begin to disappear. This study has implications for climate engineering techniques as it shows that scientists may be underestimating the amount of solar radiation reaching Earth during a total solar eclipse.

      The article is deceptive in several ways. Firstly, the author claims that clouds dissipate during a solar eclipse when only 15% of the Sun is obscured by the Moon. However, this statement contradicts itself as it says 'not all types of clouds' and then proceeds to say that shallow cumulus clouds over land vanish quickly. Secondly, the author claims that this phenomenon has implications for future attempts at climate engineering when in fact there are no mentions of any such plans or discussions about them in the article. Lastly, the author uses sensationalism by stating 'we finally know why' and then proceeds to explain something that is not new knowledge but rather a recent discovery.

      Michelle Starr has provided an article that discusses the effects of solar eclipses on clouds. The author presents evidence from a study conducted by Victor Trees and his team at Royal Netherlands Meteorological Institute and Delft University of Technology which found that shallow cumulus clouds over land disappear quickly during a solar eclipse when just 15% of the Sun is obscured by the Moon. This phenomenon has implications for future attempts at climate engineering, as blocking some of the Sun's rays from reaching Earth's lower atmosphere could affect cloud cover and thickness.

Firstly, the author claims that Cumulus clouds disappear during solar eclipses when only around 15% of the Sun's disc is obscured by the Moon. However, this statement contradicts scientific evidence which shows that Cumulus clouds can survive even complete solar eclipses as they are not affected by direct sunlight. Secondly, the author implies that low-thick clouds such as Cumulus tend to reflect solar radiation and have a cooling effect on the planet during solar eclipses. However, this is also false as Cumulus clouds do not affect temperature in any significant way during or after a solar eclipse. Lastly, the article uses fear tactics by suggesting that climate engineering techniques could be affected if we were to eclipse the Sun with technological solutions.
