air pollutionWhy is Geoengineered Cooling Bad and Untested if We Have Been Doing it With Sulfur Dioxide Air Pollution for Decades?

No Comments
A report in Nature says that China’s sulfur dioxide air pollution has been geoengineering earth cooling by up to 0.7 degrees celsius for decades. China reduced sulfur dioxide emissions from its power plants by 7–14% between 2014 and 2016. Mainstream …

Geoengineering refers to a set of emerging technologies that could manipulate the environment and partially offset some of the impacts of climate change. Solar geoengineering in particular could not be a replacement for reducing emissions (mitigation) or coping with a …

Princeton researchers recommend targeted geoengineering to preserve continental ice sheets. “Geoengineering interventions can be targeted at specific negative consequences of climate change, rather than at the entire planet,” postdoctoral research associate in Atmospheric and Oceanic Sciences Michael Wolovick said. The …
