Combating the effects of climate change by spraying aerosols into the atmosphere is a contentious topic, with many rightfully pointing out the risk of unintended side effects of such large-scale ...

It’s an idea straight out of science fiction – 'blocking the sun' to cool the atmosphere and curb or even reverse climate change. But research has shown that the hugely controversial idea of solar ...

Kimberly Prather, an atmospheric chemist at UC San Diego, is one of 20 scientists being honored by the National Academy of Sciences for extraordinary achievements, it was announced Monday. Prather was ...

New insights into the behavior of aerosols from cooking emissions and sea spray reveal that particles may take up more water than previously thought, potentially changing how long the particles remain ...

Climate ‘geoengineering’ technologies, where particles are sprayed into the stratosphere to deflect more sunlight away from a heating Earth, have a height problem. Recent studies have suggested ...

Washington, DC-- Well-understood physical and chemical processes can easily explain the alleged evidence of a secret, large-scale atmospheric spraying program, commonly referred to as "chemtrails" or ...

Aerosols and dust are critical components in the air that influence both environmental quality and human health. These particles originate from natural processes—such as wind erosion in deserts, ...

A program to reduce Earth's heat capture by injecting aerosols into the atmosphere from high-altitude aircraft is possible, but unreasonably costly with current technology, and would be unlikely to ...

Most people are familiar with the term “aerosol” by way of the spray can. If you were around during the 1970s, you might remember when consumer aerosol products like hair sprays contained ...

Former CIA Director John Brennan did not say that the government is spraying toxic chemicals into the air. Brennan spoke in 2016 at the Council on Foreign Relations about stratospheric aerosol ...

Spraying particles into Earth's atmosphere to try and cool a warming planet might sound like a good idea in theory, but it will only work if it's done properly – and even then, it could carry risks ...
