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 comments at the end of this post. He presented me with a graphic from Dr. Robert Rohde from twitter that you can find here. It is also [...]
Guest Post by Wim Röst Abstract It is said that the Earth’s surface temperature variations are controlled by [human-induced] greenhouse gases1. This is not the case. When cooling systems dominate, surface temperatures are set by the cooling system and not by the system that is warming the surface. On Earth the surface cooling [...]
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 regarded as the gold standard for paleo-atmospheric global CO2 during past interglacial and glacial periods. Antarctic CO2 does capture the multi-millennial underlying trend; however, short-term centennial trends are not [...]
Teaming with the Irish Climate Science Forum, CLINTEL has produced a 17 page catalog of “misrepresentations” in the 40 page IPCC AR6 Summary for Policy Makers, better known as the SPM. Now they have sent this error list to the IPCC Chair and other world leaders. You can read it here. The analysis [...]
Jim O'Brien, Clintel's Irish ambassador and active in the Irish Climate Science Forum regularly organizes very interesting lectures given by prominent climate scientists. Last night the well-known US climate/policy scientist Roger Pielke Jr had the virtual floor. The full talk can be viewed above or on youtube. In his lecture, Roger will [...]
The CCP (China Communist Party) is by far the biggest emitter of greenhouse gases on the planet. Is that a problem? By Richard S. Lindzen reposted from Tablet Magazine Overlooking Beijing Shougang Industrial Zone / Shutterstock.com Many of the world’s leaders appear to believe that emissions of carbon dioxide (CO₂) constitute an existential [...]
By Andy May The Old Farmer’s Almanac has been making yearly long-term weather forecasts for 230 years. We pay attention to them because they are normally 80% accurate. They did not do as well last winter but were 72% in predicting the direction of temperature change, and 78% accurate in the change in precipitation. This is pretty [...]
In response to a recent podcast by David Remnick with Swedish climate activist Andreas Malm, who advocates sabotage for critical infrastructure that underpins modern society, The New Yorker has a moral obligation to open up the climate debate and demonstrate that fears of a hellscape world are exaggerated, says Friends of Science Society. [...]
By Andy May This post was updated 9/24/2021 to reflect reader comments. The phrase “greenhouse effect,” often abbreviated as “GHE,” is very ambiguous. It applies to Earth’s surface temperature, and has never been observed or measured, only modeled. To make matters worse, it has numerous possible components, and the relative contributions of the possible [...]
By JOHN H. COCHRANE Originally published at National Review Climate policy is ultimately an economic question. How much does climate change hurt? How much do various policy ideas actually help, and what do they cost? You don’t have to argue with one line of the IPCC scientific reports to disagree with climate policy that doesn’t make [...]
