Without these gases our planet would ... which exceeds 400 parts per million is unprecedented in human history and ...

Putting aerosols in the stratosphere to reflect sunlight could prevent the shutdown of key ocean currents, but only if it is ...

Climate skeptics have long promoted the unsubstantiated theory that CO2 levels will eventually become "saturated," meaning the gas will no longer contribute to global warming.

Plants Are Using Much More CO2 Than Climate Models Assume. A study recently published in the journal Nature finds plants have been absorbing 31 percent more carbon dioxide from the atmosphere than ...

Warming of the global climate system over the past half-century has averaged 43 percent less than that produced by computerized climate models used to promote changes in energy policy.

Today’s climate models estimate that a doubling of atmospheric CO2 levels would result in warming of between 1.5°C and 4.5°C. But the results suggest a much bigger temperature rise: between 5 ...

With complex ecological modeling, scientists have found that plants may be soaking up 20% more CO2 than earlier predicted. It's no "get-out-of-jail-free card," but it highlights the crucial role ...

Modern climate change is driven by CO2 emissions, not changes in the sun. ... Carbon Brief, Oct. 5, 2017, Analysis: How well have climate models projected global warming?

The Global Carbon Budget report, published during the U.N.'s COP29 climate summit in Azerbaijan, said global CO2 emissions are set to total 41.6 billion metric tons in 2024, up from 40.6 billion ...

Plants play a huge role in shaping Earth’s climate. Through photosynthesis, they pull carbon dioxide (CO₂) out of the air. This massive exchange—called gross primary production (GPP)—is ...

Finally, some good news in the battle against greenhouse gasses: Carbon dioxide (CO2) emissions from the burning of fossil fuels are on track to rise less than 1% this year. That’s despite ...

Plants the world over are absorbing about 31% more carbon dioxide than previously thought, according to a new assessment developed by scientists. The research, detailed in the journal Nature ...
