Ein zuverlässiger Indikator für die Luftqualität in Büros, Klassenzimmern oder im Wohnzimmer ist der CO2-Gehalt. An der frischen Luft liegt die Konzentration von Kohlendioxid bei rund 400 ppm. Das ...

Global carbon dioxide emissions from fossil-fuel use will reach a record high this year despite countries’ pledges to begin lowering their climate pollution. Emissions are projected to hit 38.1 ...

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 ...

Greenhouse gas concentrations increased by a record amount in 2024 as more carbon dioxide, methane and nitrous oxide became locked in Earth's atmosphere, a World Meteorological Organization report ...

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 ...

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 ...

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 ...

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 ...

CO2 is a natural part of the planet, but too much has tipped the climate scales. Carbon dioxide may be a naturally occurring substance on Earth, but too much of its presence has contributed to global ...

The latest anomaly in the climate system that can’t be fully explained by researchers is a record annual jump in the global mean concentration of carbon dioxide in the atmosphere measured in 2024. The ...

Described as an effective and affordable LiDAR solution on a chip with solid-state beam steering, Voyant Photonics’ Carbon sensor is compact—approximately the size of a fingernail—and designed to ...
