Climeworks January 20, 2021 Engineers have built machines to scrub CO₂ from the air. But will it halt climate change? Deanna D'Alessandro, University of Sydney Machines using giant fans and filters can literally suck carbon dioxide out of the air. Sounds great – but the technology faces many challenges.
If only it were that easy. Olivier Le Moal/Shutterstock April 17, 2019 New CO₂ capture technology is not the magic bullet against climate change Chris Hawes, Keele University Carbon Engineering's clever harnessing of high-school chemistry is just a small step on the path to negative emissions.
Without rapid and dramatic changes, the world will face a higher risk of extreme weather and other effects of climate change.

Herzog, Massachusetts Institute of Technology The UN's panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.
