Machines using giant fans and filters can literally suck carbon dioxide out of the air. Sounds great – but the technology faces many challenges.

Several countries have made pledges to reduce their greenhouse gas emissions to zero by mid-century. But new research finds the remaining carbon budget will be depleted before we get there.
In the ocean, phytoplankton helped by diazotrophs play an outstanding role in withdrawing CO₂ from the atmosphere. But climate change is disturbing this delicate balance.
A person who exercises, attends sporting events as a spectator and takes their kids to the oval or swimming pool will create 935 kg of CO₂ per year if using their car.
The pandemic, along with other recent trends such as the shift towards clean energy, have placed us at a crossroad: the choices we make today can change the course of global emissions.
Our new study shows that cutting emissions now will bring benefits sooner than expected.
The Climate Change Committee has laid out a road map for net zero emissions that the UK government could follow.
Black Friday sales reveal fast fashion extremes. But how does it affect the planet?
Warmer temperatures cannot increase the amount of carbon deciduous trees absorb in each growing season, a new study suggests.
Extreme shrinkage of summer sea ice is just the latest evidence of rapid Arctic warming – and what happens in the Arctic doesn’t stay there.
Methane is a live-fast, die-young greenhouse gas but its impact on the climate can last for hundreds or even thousands of years
Despite this year’s coronavirus lockdowns, more CO2 has accumulated in the atmosphere than during the same period in 2017 or 2018.
Good ventilation can reduce the risk of catching coronavirus. An environmental engineer explains how to know if enough outside air is getting into a room and what to do if ventilation is bad.
To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.
As the world warmed from the last ice age, a rise in carbon dioxide levels stalled for nearly 2,000 years. That’s always puzzled scientists, but now they think they know what happened.
If we had not altered the composition of the atmosphere at all through emitting greenhouse gases, particulate matter and ozone-destroying chemicals, the average temperature would have remained stable.
Despite clear air as a result of the pandemic reducing human activities, our emissions still soar.
Global warming has increased plant growth and helped offset increases in carbon dioxide emissions.
From Nairobi to Los Angeles, pandemic lockdowns have cleared pollution from the skies. But those blue vistas may be temporary, and shutdowns aren’t slowing climate change.
Bubbly waters are becoming increasingly popular. While these carbonated, sometimes flavored beverages might cause slight harm to teeth, they are far better than soda. They might even be good for you.
