Geoengineering: The false dawn for our climate woes

Geoengineering, the idea of spraying certain chemicals into the stratosphere to reflect sunlight back into the space for controlling the planet’s temperature, sounds radical, risky and even outlandish to some.

A new research, published in the journal “Nature,” adds more weight to this skepticism with the finding that such solar shading could negatively affect crops and likely to wipe out the grains from lower temperatures, writes Wired.

The scientists homed in on the datasets from the events in the aftermath of two historic volcanic eruptions, which spewed aerosols into the atmosphere much the same way geoengineering proposes, reports Earther.

The study suggests that solar radiation management (SRM) can help offset the negative impact of climate change on agriculture but there will be no overall benefits, as output may fall or remain stagnant due to reduced sunlight.
