Geoengineering-new-findings

In every region of the world, the study found, temperatures grew less extreme with geo-engineering. And while geo-engineering disturbed the climate of some regions in new but small ways, it overall reduced the effects of climate change in places it was worst. “Those regions experiencing the greatest climate change are the most likely to see it reduced by [solar geo-engineering],” the study says.

There are many asterisks here. The study focuses on very vast regions: One of its areas encompasses the entire Pacific coast of South America; another includes almost all of Pakistan, India, and Bangladesh. It also does not study the lines on the planet that may matter far more: national borders. Even if rainfall remained constant in each of the studied regions, it could still cause conflict by shifting from one country to another, disrupting agriculture and water supplies. The study cannot examine that possibility.
