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 ...

For most of the space age, rocket launches were rare. Their environmental impact was also negligible. A plume here, a plume ...

For decades, satellites passing over Earth's north and south poles have experienced a flow of ions from the upper atmosphere into space. Dubbed the 'polar wind', the source of this flow had eluded ...

That would have enabled more of this organic carbon—and carbonate accumulating in shallow water around Columbia—to be ...

Rivers have long played a key role in the planet’s carbon cycle. They move and release gases like carbon dioxide (CO₂) and methane (CH₄), connecting land, air, and ocean systems. Until recently, ...

CO2 is bursting into the atmosphere like never before, up and away, like it has wings. According to climate scientists, we’re fast approaching white-knuckle time. This reinforces the outlook for 2024 ...

Daily life increasingly depends on systems of satellites orbiting Earth. As fleets proliferate, ever greater numbers of expired units will hurtle back toward the surface. Decommissioned satellites ...

Carbon dioxide makes up only about 0.04% of the Earth’s atmosphere, but that seemingly small figure ignores threat CO2 poses to the climate. Carbon dioxide accounts for 79% of U.S. greenhouse gas ...
