Atmospheric CO₂ concentrations are surging, even as emissions level out. Natural carbon sinks are showing signs of faltering ...

Higher atmospheric CO2 increases the rate of photosynthesis, and thus the amount of carbohydrates in plant leaves. Sounds beneficial, right? However, scientists have found that as CO2 levels go up, ...

New research has revealed the fundamental mechanisms that limit the performance of copper catalysts—critical components in ...

A new life-cycle assessment comparing the production impacts of three materials used in carbon dioxide capture technology has ...

Over the last decade, humanity's emissions of carbon dioxide (CO₂) have stabilized after a period of huge growth. Average growth is now down to just 0.6% per year, compared to 2% per year in the ...

Acting as a vast carbon sink, it absorbs nearly a quarter of the carbon dioxide (CO₂) emissions produced by human activities, especially from the burning of fossil fuels like coal, oil ...

A company that spreads crushed rock on farmers’ fields to help draw climate-warming carbon dioxide from the atmosphere has been awarded a $50 million grand prize in a global competition funded ...

While CO₂ doesn’t transmit viruses itself, it acts as a proxy for indoor crowding and poor ventilation. The more people in a space, the more CO₂ builds up from exhaled breath. When there isn’t enough ...

Currently, removing carbon dioxide directly from the atmosphere is estimated to cost around $600 per metric ton. Occidental’s interest in carbon capture stems from a technique known as enhanced ...

One person with deep knowledge of carbon dioxide storage issues is Philip Ringrose, professor of energy transition geoscience at the Norwegian University for Science & Technology (NTNU ...

If all goes to plan, about 625 million tonnes of carbon dioxide could be injected into the ground globally by 2033 thanks to 600 projects in play, Rystad chief executive Jarand Rystad said on ...

“In order for Mars to be warm enough to host liquid water, there must have been a lot of carbon dioxide in the atmosphere,” says Benjamin Tutolo, a researcher at the University of Calgary.
