Carbon Dioxide

Researchers have created bacteria that can effectively eat air. By carefully directing the evolution of E. coli in the lab, the team managed to wean them off their preferred diet of sugar, and make the switch to carbon dioxide in the air around them.

A new UN report, the Greenhouse Gas Bulletin, says that in 2018, the globally-averaged concentration of carbon dioxide (CO2) in the atmosphere was 407.8 parts per million (ppm), a new record high that hasn’t been seen in millions of years.

It may not come as a huge surprise that the Formula 1 World Championship generates massive amounts of CO2. It has today, however, pledged to clean up its act in a big way, with a commitment to become entirely carbon neutral by 2030.

A new report declaring a climate emergency has been signed by thousands of scientists. But it remains hopeful, outlining six steps we can take to mitigate the worst effects of climate change – provided we act sooner rather than later.

Researchers at MIT have developed a new method for pulling carbon dioxide out of a chimney flue at a power plant or even just ambient air. The new device is a specialized battery that absorbs CO2 while charging, then releases it for industrial use.

An innovative new battery design makes use of an element we’re producing too much of in carbon dioxide, and boasts an unprecedented ability to recharge 500 times.

Making cement is one of the biggest contributors of carbon emissions. Now MIT researchers have developed a new method that can clean up the process.

Researchers at the Salk Institute are approaching gene-editing technology with some very big-picture thinking, looking to tweak the genes of humankind’s most commonly sown crops so they store more carbon dioxide underground as a way of fighting climate change

It's not enough to just reduce our carbon dioxide emissions now – we need to remove some of what’s already in the atmosphere. Now, researchers at KIT have developed a simple way to turn the troublesome gas into a useful resource: by converting it into the “wonder” material graphene.

How effective would planting new trees be to combat climate change? A new study from ETH Zurich has found that Earth has room to reforest an area the size of the US, and calculates what benefits that might bring. But of course, the story is more complicated than just planting a trillion new trees.

Evolution is usually gradual, but half a billion years ago it took off at a gallop in an event that’s now known as the Cambrian Explosion. One of the leading theories is this came from a huge spike in oxygen levels, and now a team may have found where all that oxygen come from – plate tectonics.

Most oxygen in the universe isn’t in the form that we need to breathe: molecular oxygen, or O2. Now, researchers at Caltech claim to have created a reactor that can turn carbon dioxide into molecular oxygen, which could help us fight climate change here on Earth or generate oxygen for life in space.
