Q&A: Removing carbon dioxide from the atmosphere

Radu Custelcean, an organic chemist at the Department of Energy's Oak Ridge National Laboratory, is working with colleagues to develop an energy-efficient and sustainable method for scrubbing carbon dioxide directly from ...

No longer a last resort: Pulling CO2 from the air

To save the world from the worst ravages of climate change, slashing carbon pollution is no longer enough—CO2 will also need to be sucked out of the atmosphere and buried, a landmark UN report is expected to say on Monday.

Universal mechanism of methane formation discovered

The formation of the greenhouse gas methane is based on a universal mechanism. Scientists at Heidelberg University and the Max Planck Institute for Terrestrial Microbiology in Marburg have made this discovery. The interdisciplinary ...

Climate: Removing CO2 from the air no longer optional

The burning question going into the Glasgow climate summit is whether major economies can, by 2050, reduce emissions enough to deliver a carbon neutral world in which humanity no longer adds planet-warming gases to the atmosphere.

Global warming begets more warming, new paleoclimate study finds

It is increasingly clear that the prolonged drought conditions, record-breaking heat, sustained wildfires, and frequent, more extreme storms experienced in recent years are a direct result of rising global temperatures brought ...

Geoengineering: 'Plan B' for the planet

Dismissed a decade ago as far-fetched and dangerous, schemes to tame the effects of global warming by engineering the climate have migrated from the margins of policy debates towards centre stage.
