Blocking the sun to control global warming

It sounds like something out of a bad science fiction movie—artificially blocking sunlight to keep global warming from overheating the Earth. Nevertheless, a small cadre of researchers is studying the option—so that if ...

Scientists may be cracking mystery of big 1872 earthquake

Geologists may be close to cracking one of the biggest seismological mysteries in the Pacific Northwest: the origin of a powerful earthquake that rattled seven states and provinces when Ulysses S. Grant was president.

Can solar geoengineering mitigate both climate change and income inequality?

New research from the University of California San Diego finds that solar geoengineering—the intentional reflection of sunlight away from the Earth's surface—may reduce income inequality between countries.

Could planting trees in the desert mitigate climate change?

As the world starts feeling the effects of increasing atmospheric carbon dioxide and consequent global temperature rise, researchers are looking for a Plan B to mitigate climate change. A group of German scientists has now ...

Global warming pause linked to sulfur in China

Scientists have come up with a possible explanation for why the rise in Earth's temperature paused for a bit during the 2000s, one of the hottest decades on record.

Researchers find unintended consequences of geoengineering to slow climate change

Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting ...

Will we ever colonize Mars?

Mars. It's a pretty unforgiving place. On this dry, dessicated world, the average surface temperature is -55 °C (-67 °F). And at the poles, temperatures can reach as low as -153 °C (243 °F). Much of that has to do with ...

Could artificially dimming the sun prevent ice melt?

With methods of so-called geoengineering, the climate could theoretically be artificially influenced and cooled. Bernese researchers have now investigated whether it would be possible to prevent the melting of the West Antarctic ...
