Proposals to inject sulfate aerosols into the upper atmosphere to block and scatter sunlight and reduce global temperatures could, some say, also increase crop yields because of reduced heat stress on plants. A new study shows that other effects counterbalance the positive effects of reduced heat stress. Specifically, blocking sunlight reduces photosynthesis, which offsets any improvement from slightly cooler temperatures. The team based their analysis on the effects from two previous volcanic eruptions.
