Should Government Control Scientific Research?

By Andy May This is the transcript of a talk I gave to the ASME (The American Society of Mechanical Engineers) South Texas Section January 20, 2022 Federal money allows unelected bureaucrats to control scientific research. They dictate the projects, and often the outcomes. They use selective leaks to the press to embarrass anyone [...]

IEA: Global Coal Power Generation to Reach a New High in 2022

By Andy May It’s official, the IEA believes that coal-powered electricity generation will rise 9% in 2021 to an all-time high, once the final numbers are in. For the details see their new report here. It is not paywalled. The rise is driven by China and India, these countries account for two-thirds of global coal [...]

Total Energy Used and petrochemicals

By Andy May It came up in conversation: How much oil and gas goes into plastics and fertilizer production? It turns out the IEA has a 2018 report on this very topic. They have a separate 2020 report on total energy used in 2019. The reports contain some interesting graphs and data. Below is a comparison of total [...]

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 posted on twitter by Robert Rohde implying they correlated well. The two records appear to correlate because the resulting R2 is 0.87. The least square’s function used made the global [...]

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 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 [...]

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 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 [...]

The Old Farmer’s Almanac Seasonal Forecasts

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 [...]

The greenhouse effect, summary of the Happer and Van Wijngaarden paper

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 [...]

False and misleading “fact check” about Connolly, et al., 2021

By Andy May Dr. Ronan Connolly and his co-authors respond to obvious false claims, in a supposed “fact check” about their latest paper on how solar variability may be affecting the climate. We applaud Dr. Ronan Connolly, Dr. Willie Soon, and Dr. Michael Connolly for rapidly and publicly calling out this fraudulent fact check. Misinformation [...]

Nature promotes frivolous lawsuits

By Andy May A Dutch joke*: “The Judge asks an attorney pleading his case: ‘Am I ever to hear the truth?’ The attorney responds: ‘No, my Lord, only the evidence.'” It is safe to say that no evidence exists that man-made climate change has harmed anyone. Further man-made climate or climate change [...]
