Reducing carbon emissions may not be enough anymore, direct CO2 capture might be the way to go

Appeals to remove the amount of CO2 in the atmosphere have begun to enter the political arena, and could become a contentious issue at the UN negotiations in Glasgow and beyond, experts say.

Wildfires emitted record levels of more than 2.5 billion tonnes of CO2 in July and August alone

Even the Arctic Circle was on fire, releasing some 66 million tonnes of CO2 from June through August, with nearly a billion tonnes from Russia as a whole over the same period.

How much of the world’s energy comes from fossil fuels? Can renewables replace it all?

Fossilisation of trees moved enormous amounts of carbon from the air to underground, leading to a decline in atmospheric CO₂ levels

Value of nature: What is the cost of the trees in the Gabon forests that suck in carbon dioxide

"If a tree is standing it's worth nothing, if you cut it down it's worth something, but that's useless for the planet," said Carlos Manuel Rodriguez, head of the Global Environment Facility.

Nitrous oxide, potent greenhouse gas, are on the rise from ocean dead zones

The oceans currently account for around 25 percent of global N2O emissions, and scientists are working to improve estimates of marine contributions.

To reach net-zero emissions and remove CO2 from the air, scientists drawn up six priorities

Information on CO₂ removal is found in academic literature and focuses on a global scale but actually doing it will involve everyone from local farmers to international financiers.

Swiss voters narrowly reject proposed carbon dioxide law to fight climate change, show exit polls

The proposal would have revised and strengthened an existing law that was aimed at reducing CO2 emissions by 2030 and enacted new taxes on CO2-generating fuel and natural gas

Brazil's Amazon forest released more CO2 than it absorbed over the last decade: Study

If the region were to become a source of CO2 rather than a "sink", tackling the climate crisis will be that much harder.

Carbon might boost forest, grassland growth but absorption capacity of soil decreases

The new study adds to growing evidence that the terrestrial carbon sink is weaker than once thought.

Greenland's ice sheet has completely melted at least once in the last million years

If the ice sheet were to vanish altogether, it would lift global oceans by nearly seven metres.
