Growing carbon dioxide levels are more evidence that countries have made little progress toward the goal set in Paris in 2015 of limiting warming to 1.5 degrees Celsius.

The amount of carbon dioxide in Earth's atmosphere reached 419 parts per million in May, its highest level in more than four million years, according to NOAA. Fossil fuel use is driving the increase.

But despite carbon dioxide's power to heat the planet, it's very diffuse, making up less than 1% of the atmosphere. That makes it tricky to capture from the air in large quantities.

The ocean helps relieve our atmosphere of a lot of the excess carbon dioxide we've pumped into it. Here's how its "twilight zone" makes that happen, and how the impacts of climate change make it ...

Voila! You've just removed CO2 from the atmosphere. But since carbon dioxide makes up such a tiny fraction of the air we breathe, DAC facilities need to take a whole lot in. This requires energy.

A global analysis reveals that most carbon dioxide emitted by rivers derives not from modern plant material, as was thought, but from ancient, buried carbon. A global analysis reveals that most ...

It also remains true that China’s per capita carbon dioxide emissions are much lower than those in the U.S. In 2018, annual emissions in the U.S. stood at 16 metric tons per person, while those ...

Another climate milestone soared by last weekend when scientists announced that atmospheric carbon dioxide levels hit 415 parts per million for the first time ever (Climatewire, May 7). It’s the ...

Dr. Peil also said that carbon dioxide does not cling to the masks so that it is re-inhaled. He said, “And even if it did, it would be a very small amount.

Scientists have developed a material with photosynthetic bacteria that convert carbon dioxide into a mineral skeleton. The material hardens over time, so it could be used for buildings, they say.

California-based Calnetix Technologies announced on Thursday (April 13) that its high-speed blower system was deployed with NASA's Four Bed Carbon Dioxide Scrubber (FBCO2) that has been operating ...

Around 31.5 billion metric tons of carbon dioxide were emitted in 2020, reports Nikolaj Skydsgaard of Reuters. Orca will be able to capture the equivalent of the annual emissions made by 790 cars.
