Two New Studies Look Into “Planet-Hacking” Proposals for Slowing Climate Change
Two new studies have been published in Science outlining research on a pair of geoengineering methods, sulphur atmospheric injection and cirrus cloud modification, that could prove helpful if Earth’s climate reaches catastrophic levels. While the researchers behind these studies hope that the methods will never become necessary, they assert that researching them is important just in case a climate red button is ever needed.
The first method would involve attempting to mimic the effects of volcanic eruptions. Using dispersal planes, we would inject enough sulphur into the atmosphere to deflect a significant amount of solar radiation away from Earth, thus decreasing its surface temperature.
The second method is to modify cirrus clouds. These clouds are adept at trapping heat in the atmosphere, having a similar effects on the planet as greenhouse gases. The proposed geoengineering method would be to “seed” these clouds with tiny particles of chemicals, desert dust, or pollen in order to break them apart and let more heat escape.
