The simple physics model – using IPCC’s outflow proportional to level and e-times –proves natural CO2 controls atmospheric CO2. As of 2020, natural CO2 has added about 100 ppm, and human CO2 only 33 ppm, to IPCC’s...

Recent studies looking at carbon-sequestering microbes suggest we still have a lot to learn about the ocean’s biological carbon pump.

The mutual relationships between forests and climate are actually really rather more complex and not fully understood.

They also showed that it is very illogical to think that a slight increase in the up-flux cannot be compensated by a larger down-flux. It’s like increasing the heat energy flow in a house by 5% and expecting that the temperature...

However, Virginia Tech researchers discovered that when using the accepted numbers for soil respiration, that number in the carbon cycling models is no longer balanced.

The increase in 12C in the atmosphere is, in my opinion, weak evidence that the annual increases are driven only by fossil fuel sources. The atmosphere can’t tell ‘anthropogenic’ carbon dioxide from natural carbon...

Predictions of future climate change require a clear and nuanced understanding of Earth's past climate. In a study published today in Science Advances, University of Hawai'i (UH) at Mānoa oceanographers fully reconciled...

Previous estimates of the movement of carbon (known as "flux") between the atmosphere and oceans have not accounted for temperature differences at the water's surface and a few metres below.

Watching a child grow is seeing carbon dioxide in action. Plants turn CO2 into the food we eat to live and grow on. “You can’t live on air” is a common saying but that is just what we do; we live on air and water.

Reposted from Dr. Roy Spencer’s blog February 6th, 2020 by Roy W. Spencer, Ph. D. Well, as I suspected (and warned everyone) in my blog post yesterday, a portion of my calculations were in error regarding how much CO2 is...

University of Bristol The Earth’s carbon cycle is crucial in controlling the greenhouse gas content of our atmosphere, and ultimately our climate...

From Phys.org January 4, 2019 by Emily Pontecorvo, American Geophysical Union Tropical forests store about a third of Earth’s carbon and about two-thirds of its above-ground biomass. Most climate change models predict...

Finding a healthy alternative to the prevailing growth model that has strained the planet to bursting is the holy grail of environmental economics. And it looks like maybe we've found it. George Monbiot, the most dynamic...

From a long line of missing things in climate models and the University of Texas at Austin: Symbiotic fungi inhabiting plant roots have major impact on atmospheric carbon, scientists say AUSTIN, Texas — Microscopic fungi...

One has to wonder though, since CO2 residence time has been said to be anywhere from  five year to hundreds, or even thousands of years, with no solid agreement yet, how they can be so sure of themselves? From the …...
