Pollution in Northern Hemisphere helped cause 1980s African drought

smokestacks

Air pollution in the Northern Hemisphere in the mid-20th century cooled the upper half of the planet and pushed rain bands south, contributing to the prolonged and worsening drought in Africa’s Sahel region. Clean air legislation in the 1980s reversed the trend and the drought lessened.

Keeping beverages cool in summer: It’s not just the heat, it’s the humidity

Sweat on a can of Miller beer.

Drops forming on the outside of your drink don’t just make the can slippery. Experiments show that in hot, humid weather, condensation heats a drink more than the surrounding air.

International study: Where there’s smoke or smog, there’s climate change

Scientists taking snow samples in Greenland.

A new international assessment found that soot, or black carbon, is a major contributor to global warming — second only to carbon dioxide.
