Drastic and Irreversible Climate Geoengineering Worries Experts

The Earth is too hot and only getting hotter, according to governments and global bodies such as the United Nations; and the efforts to reduce carbon dioxide aren’t having enough of an effect. “The world is passing through the 1.5°C ceiling and is headed much higher unless steps are taken to affect Earth’s energy imbalance,” James Hansen, the previous director of the NASA Goddard Institute for Space Studies, warned in January.
