Ancient enzymes show life’s nitrogen signal stayed unchanged for billions of years, helping scientists read early Earth.

As the climate crisis becomes a part of daily life with unprecedented heat waves and cold snaps, technology to effectively remove greenhouse gases is emerging as a critical global challenge. In ...

A joint research team has developed a highly efficient photocatalyst that can convert carbon dioxide into the high-value-added fuel, methane, using sunlight, while explaining its operating principles.

The projected rise in CO2 emissions in 2025 is driven by growth in coal, like the coal-fired plant pictured, as well as oil and gas, according to the 2025 Global Carbon Budget Report. Global carbon ...

A new copper-magnesium-iron catalyst transforms CO2 into CO at low temperatures with record-breaking efficiency and stability. The discovery paves the way for affordable, scalable production of carbon ...

GENEVA (AP) — Heat-trapping carbon dioxide levels in the atmosphere jumped by the highest amount on record last year, soaring to a level not seen in human civilization and "turbo-charging" the Earth's ...

Achieving net-zero greenhouse gas emissions by 2050 will require removing carbon dioxide from the atmosphere, according to the Intergovernmental Panel on Climate Change, the world’s foremost authority ...

The award-winning science writer Peter Brannen makes the case for an often vilified compound in “The Story of CO2 Is the Story of Everything.” By Jaime Green Jaime Green is the author of “The ...

Is carbon dioxide a pollutant? A small but vocal group of researchers, authors and government officials say it is time to change the definition. Greenhouse gases including CO2 are considered air ...

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. When ...

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 ...

For the first time, the seasonal peak of carbon dioxide concentrations in the atmosphere exceeded 430 parts per million (ppm) at NOAA’s Mauna Loa Observatory on Hawaii, scientists from NOAA and ...
