The Impact of Human CO2 On Atmospheric CO2 – Summary

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…

The Ocean Is Still Sucking Up Carbon—Maybe More Than We Think

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

Will Planting Trees Reduce Global Warming?

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

Why is the CO₂ Concentration Rising?

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…

Estimates of the carbon cycle – vital to predicting climate change – are incorrect, Virginia Tech researchers show

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.

CARBON CYCLE

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…

Claim: Climate and carbon cycle trends of the past 50 million years reconciled

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…

Ocean carbon uptake widely underestimated

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 CO2 feed the world

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…

Corrected RCP Scenario Removal Fractions

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…

Ice sheets impact core elements of the Earth’s carbon cycle

University of Bristol The Earth’s carbon cycle is crucial in controlling the greenhouse gas content of our atmosphere, and ultimately our climate. Ice sheets which cover about 10 percent of…

Climate warming experiment finds unexpected results

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…

Now it's the fungi carbon footprint that isn't in climate models

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…

Apparently, 4 degrees spells climate doom

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,…

US Carbon Dioxide Emissions – down by source

I’ve often said my email is like a fire hose. Here’s an example of something that got lost in the stream and I didn’t find it until last night while…

Hump Day Hilarity – DECC The Halls

Josh writes of this development in the UK: Ed Davey’s performance yesterday at the Energy and Climate Change Committee, posted here, was a mix of horror and farce. DECC seem to live in…

Is the Bern Model Non-Physical?

Guest essay by Joe Born Is the Bern Model non-physical? Maybe, but not because it requires the atmosphere to partition its carbon content non-physically. A Bern Model for the response…

Same headline, different year

Last year it was this headline, including a similar image: CO2 emissions reach record in 2012, driven by China This year, from the University of East Anglia, via Eurekalert, a…

Another modeling shortcoming…

From the Yale School of Forestry & Environmental Studies Carbon cycle models underestimate indirect role of animals Animal populations can have a far more significant impact on carbon storage and…

CO2 calculation in the global carbon cycle may be off due to a depth error

It seems that a simple assumption about where to measure CO2 in the ocean surface has drastic implications. via The Hockey Schtick New paper finds global carbon cycle datasets may…

Vicious Carbon Cycles

From the Helmholtz Association Extreme weather, climate and the carbon cycle Extreme weather and climate events like storms, heavy precipitation and droughts and heat waves prevent the uptake of 3…

Earth's self regulation of Carbon Dioxide is remarkably stable

From CSIRO: “What we learned is that in spite of droughts, floods, volcano eruptions, El Niño and other events, the Earth system has been remarkably consistent in regulating the inter-annual…

The bombtest curve and its implications for atmospheric carbon dioxide residency time

Studies of Carbon 14 in the atmosphere emitted by nuclear tests indicate that the Bern model used by the IPCC is inconsistent with virtually all reported experimental results. Guest essay…

Carbon sequestration driver: Spiders, why did it have to be spiders?

From the Yale School of Forestry & Environmental Studies New study shows predators affect the carbon cycle A new study shows that the predator-prey relationship can affect the flow of…
