Unfortunately, too many individuals and governments are locked into the false mindset that CO2 is a pollutant and so research has progressed but little on this front of late.

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…
Sorry, But Hard Science is Not Done This Way.
The short story: Can we detect a change of CO2 in the air after emission reductions following Covid-19 lockdowns?
Explaining Mauna Loa CO2 Increases with Anthropogenic and Natural Influences
I’m mostly trying to show how difficult it is to determine cause-and-effect from the available statistical data analysis alone.
The Many Benefits of Rising Atmospheric CO2 — An Introduction
Atmospheric carbon dioxide: you can’t see, hear, smell or taste it. But it’s there—all around us—and it’s crucial for life. Composed of one carbon and two oxygen atoms, this simple…
NASA Science Enables First-of-its-Kind Detection of Reduced Human CO2 Emissions
For the first time, researchers have spotted short-term, regional fluctuations in atmospheric carbon dioxide (CO2) across the globe due to emissions from human activities.
Stanford Research Finds Drought Alters Mammoth Mountain’s Carbon Dioxide Emissions
“This really shows how the solid Earth is coupled to climate and the things that go on at the surface,” said Hilley, professor of geological sciences in Stanford’s School of Earth,…
Anthropogenic CO2 and the Expected Results from Eliminating It
This is the fourthin a series dealing with anthropogenic CO2; in particular, why no measurable decline in atmospheric CO2 occurred during the most severe reduction in anthropogenic emissions that has…
Rising atmospheric CO2 concentrations globally affect photosynthesis of peat-forming mosses
Although peatlands cover only three per cent of the global land surface, they store a third of the global soil carbon. Thus, uptake of CO2 by peat mosses is important,…
No returning to climate of the past even with CO2 reduction
It is impossible to properly reflect the complex climate system if only the average global temperature and precipitation levels are considered when creating mitigation policies to prevent climate change, such…
CO2 Party: Having Fun with Probabilities
Fundamentally, it appears that the increase in CO2, as exhibited during the Fall-Spring ramp-up phase, is not being matched by the drawdown phase in Summer, despite the slope of the…
Unbalanced At The Top
Guest Post by Willis Eschenbach The “CO2 Roolz Temperature” theory goes like this: • The amount of atmospheric CO2 increases. • This absorbs more upwelling longwave radiation, which leads to…
Autocorrelation in CO2 and Temperature Time Series
By Andy May In my last post I plotted the NASA CO2 and the HadCRUT5 records from 1850 to 2020 and compared them. This was in response to a plot…
CO2 and Temperature
By Andy May I had a very interesting online discussion about CO2 and temperature with Tinus Pulles, a retired Dutch environmental scientist. To read the whole discussion, go to the…
Holocene CO2 Variability and Underlying Trends
Guest Post by Renee Hannon Introduction This post compares CO2 data from Antarctic ice cores during the Holocene interglacial period with other publicly available CO2 datasets. Antarctic ice CO2 is…
The Real Cost Of Green Steel
Guest Post by Willis Eschenbach There is much agitation in the climatosphere about the amount of “coking coal” used in making steel. A number of allegedly smart folks are working…
Holocene Antarctic CO2 Variability or Lack Of
Guest Post by Renee Hannon Introduction This post examines CO2 ice core measurements from Antarctica during the Holocene Epoch. The key CO2 dataset for paleoclimate studies is the EPICA Dome…
Scientists show a single catalyst can perform the first step of turning CO2 into fuel in two very different ways
The results represent an important step toward unifying the understanding of catalytic reactions in these two very different conditions with distinct driving forces at play, said Thomas Jaramillo, professor at…
A CO2 Puzzle
Guest Post by Willis Eschenbach Back in 1987, V. Ramanathan noted that we can measure the very poorly named “greenhouse effect”. This effect has nothing to do with greenhouses. Instead,…
Greenland Ice Core CO2 during the past 1,000 years
Guest Post by Renee Hannon IntroductionThis post compares CO2 ice core measurements from Greenland to those from Antarctica over the last millennium. Paleoclimate studies typically use only Antarctic ice cores…
The temperature–CO2 climate connection: an epistemological reappraisal of ice-core messages

The CO2 Shift; Ice Age to Gas Age
Guest Post by Renee Hannon IntroductionThis post examines CO2 data collected from Antarctic ice cores and compares CO2 measurements in both ice age and gas age. The age of trapped…
