Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet. cancel the launch.

However, climate models to date have mischaracterized the effects of soot in the atmosphere, according to Jacobson, director of Stanford’s Atmosphere/Energy Program. Black carbon is highly efficient at absorbing solar radiation in the atmosphere, just like a black shirt on a sunny day. Tags: Climate Change Emissions.
