Carbon dioxide in the atmosphere is increasing at rates that are incompatible with staying below 1.5 degrees Celsius (2.7 degrees Fahrenheit) of global warming, a Met Office study warns.

Concentrations of carbon dioxide (CO2) are now more than 50% higher than before humans started burning large amounts of fossil fuels. Last year, fossil fuel emissions were at record highs ...

The quest to reduce our carbon footprint has driven significant efforts toward developing a system to eliminate greenhouse gas emissions, such as carbon dioxide, at their source. Carbon emissions from ...

The PaO2 is one of the components measured in an arterial blood gas (ABG) test, which also reports oxygen (O2) saturation, bicarbonate (HCO3), the partial pressure of carbon dioxide (CO2), and the pH ...

Jan 15 (Reuters) - A U.S. regulator on Wednesday proposed new rules to strengthen safety requirements for carbon dioxide and hazardous liquid pipelines at a time when carbon capture technologies ...

At scale, this straightforward recycling process could substantially reduce waste, energy use, and carbon dioxide emissions associated with production. The study’s co-authors include Rice graduate ...

They absorb carbon dioxide from the air while releasing water vapour and oxygen via photosynthesis – the process by which plants take in carbon dioxide and fix energy. Because of this ...

Carbon capture is a front-running technology for removing CO 2 from the atmosphere, but finding sustainable ways to store that carbon can be a challenge. A new study examines ways that carbon ...
