Swiss start-up Climeworks is working to capture CO2 from the atmosphere and recycle it into a resource. Their ambitious goal is to have zero net emissions of CO2 by using it to grow plants or make carbon-neutral fuel.
Burning fossil fuels to meet rising energy demand has pushed carbon dioxide emissions to a record high. Can innovation save us from global warming?
A range of technologies — loosely defined as 'geoengineering' — are being explored as responses to climate change. Yet their effectiveness, and whether they should be implemented at all, is debated among scientists.
The fires in Australia are a major factor in one of the biggest rises in atmospheric CO2 in 60 years, experts have said. Meanwhile, a team is trying to recover the bodies of three US firefighters killed in a plane crash.
Atmospheric levels of planet-warming carbon dioxide have hit a record high of more than 415 parts per million. The accelerated rise of man-made greenhouse gas emissions has scientists alarmed.
