China has launched the world’s first carbon dioxide–based power generator, using supercritical CO2 instead of steam to produce electricity with over 50% efficiency. The system harnesses industrial ...

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 ...

Surging emissions from wildfires may have been behind the increase, which was the largest since modern measurements began more than half a century ago. By Raymond Zhong and Sachi Kitajima Mulkey The ...

The increase in the amount of carbon dioxide in the atmosphere last year was the biggest ever recorded, the United Nations said Wednesday, calling for urgent action to slash emissions. Levels of the ...

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 ...

A new bug in the XenForo or Ars Civis? Subscript and Superscript used to work just fine previously. Steps to repro: Write any chemical formula in plaintext, e.g. O2F2 for FOOF (full disclaimer – no ...

Concrete has been around for millennia, but Terra CO2 thinks it has a better way to make the ubiquitous building material, and investors appear to agree. The Golden, Colorado-based startup recently ...

Every query typed into a large language model (LLM), such as ChatGPT, requires energy and produces CO2 emissions. Emissions, however, depend on the model, the subject matter, and the user. Researchers ...

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 ...

An observatory high on Hawaii's Mauna Loa volcano that measures carbon dioxide in the atmosphere has reported its highest ever seasonal peak concentration of the greenhouse gas. For the first time, ...
