By Andy May For decades We have been told that we must not let global warming exceed two degrees Celsius above the “pre-industrial” global average temperature. Recently the IPCC lowered this limit to 1.5°C. In the latest IPCC report, called AR6, pre-industrial is defined as before 1750, but they use global temperatures from 1850-1900 as representative [...]
By Andy May The U.S. Constitution was finally approved in 1787, after much debate. It reserved a specific list of powers for the federal government and the first ten amendments, or the “Bill of Rights,” reserved many powers for the citizens and states. The Bill of Rights imposed clear limitations on the federal [...]
Guest Post by Renee Hannon Introduction This post examines sample spacing for CO2 measurements in Antarctic ice cores during the past 800,000 years to better understand if gaps in sampling are too large to capture centennial fluctuations. The IPCC states: “Although ice core records present low-pass filtered time series due to gas diffusion and [...]
U.S. progressives are convinced that fossil fuels must be replaced with renewables by 2050. The IEA even has a plan to do it. How will this work? Unlike progressives we value observational data over ideology, so let’s examine the data. According to ExxonMobil’s 2021 Outlook for Energy the world consumed 89.4 BBOE (billions of barrels of oil equivalent) of primary [...]
By Andy May An interesting PNAS article discusses the deepest portion of the Camp Century Greenland Ice core. It is not paywalled. The researchers, led by Andrew Christ (Dept. of Geology, University of Vermont) found evidence of an ice-free vegetated environment at the base of the Camp Century ice core roughly one million years ago. This [...]
The IPCC AR5 report was published in 2013 and the CMIP5 climate models they used, have been shown to predict faster warming than observed in the tropical troposphere at a statistically significant level by Ross McKitrick and John Christy.[1] This problem is acknowledged and discussed in the latest AR6 report, published in 2021, but brushed aside as unimportant. In [...]
In my last post, I explained how the IPCC attempts to use climate models to show humans have caused the recent global warming. Models are useful for testing scientific ideas, but they are not proof an idea is correct unless they successfully and accurately predict future events. See the story of Arthur Eddington’s test [...]
The featured cartoon is by Josh, who graciously gave me permission to use it, his website is here. This cartoon is in Josh’s 2022 calendar, I think he still has a few to sell. My latest book,[1] just released, is about a climate change debate between Professor David Karoly of the University of Melbourne and Professor William [...]
So, what happened to European efforts to develop a shale gas and oil industry like we have in the United States? Recent shortages, Putin’s invasion of Ukraine, and high energy prices have proven that we are not remotely prepared to make it without fossil fuels. As Holman Jenkins explains in yesterday’s Wall Street Journal (Jenkins, [...]
By Andy May Update: Unfortunately, the Texas Supreme Court declined to review the court of appeals decision that the California governments do not have sufficient minimum contacts with Texas. This means the court cannot intervene in the case. However, the lower appeals court did say, according to the Texas Civil Justice League: “The court of [...]
