I’ve heard of global warming, of course, but what on Earth is “global dimming?” Max S. Seattle, Wash. Global dimming is a less well-known but real phenomenon resulting from atmospheric pollution. The ...

The White House Office of Science and Technology Policy has announced a five-year research plan to study the possible ways of implementing “solar geoengineering” — reflecting some of the sun’s light ...

The sun rises each day, but the amount of sunlight reaching Earth’s surface is not as constant as we might think. A new study published inAdvances in Atmospheric Science reveals significant ...

Solar radiation management projects, also known as sun dimming, seek to reduce the amount of sunlight hitting the Earth to counteract the effects of climate change. Global dimming can occur as a ...

relates how the first signs of global dimming came in the 1980s when one scientist—who measured sunlight amounts over Israel in the 1950s—found a 22 percent drop in sunlight 20 years later. reports ...

A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases – sunlight blocked by dust, pollution and other aerosol particles – appears to have lost ...

Reversing a decades-long trend toward "global dimming," Earth's surface has become brighter since 1990, scientists are reporting today. The brightening means that more sunlight--and thus more heat--is ...

Scientists are proposing an ingenious but as-yet-unproven way to tackle climate change: spraying sun-dimming chemicals into the Earth's atmosphere. The research by scientists at Harvard and Yale ...

Stepping into a "minefield" about how to slow global warming, scientists in developing nations have won new funds to study whether dimming sunshine by mimicking volcanic eruptions can be a ...

Global mean downward surface shortwave radiation (DSSR) changes. (A) temporal evolution and (B) trends of DSSR during the historical period (1959-2014) simulated by the model; (C) contribution of ...

WASHINGTON (Reuters) - Visibility on clear days has declined in much of the world since the 1970s thanks to a rise in airborne pollutants, scientists said on Thursday. They described a "global dimming ...
