Geoengineering Could Lead To Lower Crop Yields: New Study

A new study has determined that spraying the skies with chemicals to combat global warming will likely come with the unintended side-effect of reducing crop yields

Researchers with the University of California, Berkeley, have published a new study which calls into question the scientific efforts to block sunlight via climate engineering, also known as geoengineering. Geoengineering is the deliberate and large-scale manipulation of the weather and climate using a variety of technologies. One popular form of geoengineering being explored by scientists is known as Solar Radiation Management (SRM), a process which involves spraying aerosols from planes equipped with particulates designed to reflect sunlight in an effort to combat “anthropogenic global warming.”

However, the UC Berkeley team has found new evidence that sun-blocking material will likely also reduce the yields of certain crops. The researchers came to this conclusion by studying previous volcanic eruptions in Mexico and the Philippines. The 1991 eruption of Mount Pinatubo in the Philippines and El Chichon in Mexico in 1982 caused a decrease in wheat, soy, and rice production due to the volcanic ash blocking sun light.
