Stratospheric aerosol injection, the idea of spraying sulfur dioxide into the upper atmosphere to cool the planet, is one of the most controversial topics in climate science, with scientists engaged ...

Advocates say there’s a growing ethical obligation for researchers to explore alternative solutions to climate change. Manipulating the Earth’s natural systems to counter global warming has long been ...

One underappreciated, terrifying aspect of climate change is that the situation would be even worse if our air pollution weren’t cooling us. Aerosols from air pollution and smoke are providing a ...

Over the Northern Hemisphere’s summer, the world’s temperatures hovered near 1.5° C above pre-industrial temperatures, and the catastrophic weather events that ensued provided a preview of what might ...

After decades of trying to stop Earth from heating up, scientists are exploring how to reverse climate change and maybe even cool the planet back down. Could clouds be brightened so they reflect more ...

Could blocking the sun help reverse climate change? Scientists say maybe, thanks to solar geoengineering. The emerging solution is designed to cool the Earth and prevent catastrophic warming. Despite ...

Editor’s note: Marshall Brain – futurist, inventor, NCSU professor, writer and creator of “How Stuff Works” is a contributor to WRAL TechWire. Brain takes a serious as well as entertaining look at a ...

The agency is being asked to strengthen a toothless rule that requires only a heads-up before experiments to modify the weather. Picture this: As a Phoenix heat wave is killing hundreds of people, an ...

Last year a team of Harvard scientists had an idea involving a large balloon and a small amount of chalk dust. They devised an experiment in which a weather balloon would release less than 2 kilograms ...

Last February, two balloons that were launched from Reno, Nevada, flew to Northern California. Along the way, as planned, they released a small amount of sulfur dioxide, a gas that has a cooling ...

This article originally appeared on Undark. In April, in the Bay Area town of Alameda, scientists were making plans to block the sun. Not entirely or permanently, of course: Their experiment included ...
