Letters: Science alone can’t solve climate change

"Tim Radford’s article “Geo-engineered crops may help — and harm” (Re: Boulderganic, Aug. 23, 2018) points out the interesting suggestion that we might be able to mimic the effect of volcanic eruptions by spewing aerosols into the atmosphere, creating a synthetic “sunscreen” that will cool the planet. He discusses research that looked at crop yields after major volcanic eruptions and found that while plants do better with cooler temperatures, they do worse because of the reduced amount of sunlight."
