Carbon dioxide removal (CDR) technologies will need to be deployed at rates even faster than those seen for solar power, if the world is to have a chance of limiting global warming to 1.5C by 2100, ...

Novel forms of CO 2 removal must expand at ‘highly ambitious rates’ if world is to limit global heating to 1.5C, says study Humanity must suck carbon out of the atmosphere with new technologies even ...

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 ...

The amount of carbon dioxide detected in the atmosphere hit a record high in April. CO 2 levels averaged about 431 parts per million (ppm) over that month, according to data collected at the National ...

As humans burn fossil fuels and pump carbon dioxide into the atmosphere, we are heating up the planet. But there is another alarming impact of this climate pollution: it may be changing the chemistry ...

Climate change is one of the most pressing global challenges in the present times. Increasing carbon dioxide (CO 2) concentrations in the atmosphere are a major factor contributing to this phenomenon.

Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue.

Scientists have created a device that captures carbon dioxide and transforms it into a useful chemical in a single step. The new electrode works with realistic exhaust gases rather than requiring ...

There is widespread recognition that efforts to meet global climate targets cannot be met by curbing new carbon dioxide emissions alone and will also require removing carbon from the atmosphere at ...

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 ...

Atmospheric carbon dioxide levels jumped by a record amount in 2024 to push concentrations to their highest point since measurements began, the UN’s World Meteorological Organization (WMO) has ...

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 ...
