Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that ...

A team of researchers was able to assemble a rare three-dimensional view of how carbon moves through the atmosphere across different regions and over time.

Novel forms of CO2 removal must expand at ‘highly ambitious rates’ if world is to limit global heating to 1.5C, says study ...

Several start-ups have tried to grow seaweed to remove atmospheric CO2, but this could affect the levels of nutrients in the ...

Mark Herz: This is GBH’s Morning Edition. The amount of carbon dioxide in our atmosphere is increasing faster than ever. One global monitor showed that peak to peak from 2022 to 2024, we saw the ...

About half of all the CO2 humans have ever emitted still hangs over our heads, literally. Since the Industrial Revolution began, that totals nearly 1,000 metric gigatons stuck in the atmosphere. Now, ...

Earth’s atmosphere now has more carbon dioxide in it than it has in millions — and possibly tens of millions — of years, according to data released Thursday by the National Oceanic and Atmospheric ...

Carbon dioxide is accumulating in the atmosphere faster than ever—accelerating on a steep rise to levels far above any experienced during human existence, scientists from NOAA and the Scripps ...
