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 coalContinue reading “IEA: Global Coal Power Generation to Reach a New High in 2022”

Viral, A Review

By Andy May Alina Chan is a molecular biologist specializing in gene therapy and cell engineering at the Broad Institute of MIT and Harvard. She partnered with the famous science writer, Matt Ridley, to write Viral, the Search for the Origin of COVID-19. The book was published November 16, 2021, and the combination of Dr.Continue reading “Viral, A Review”

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 aContinue reading “Total Energy Used and petrochemicals”

Help, what is happening with our universities?

By Prof. Dr. IR. Guus Berkhout This is an English translation of a letter by Guus Berkhout of CLINTEL that was published in De Telegraaf, the largest newspaper in The Netherlands earlier this week. In recent years we have seen the strangest things happening to our universities. Professors must be extremely careful about what theyContinue reading “Help, what is happening with our universities?”

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’sContinue reading “Autocorrelation in CO2 and Temperature Time Series”

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. ItContinue reading “CO2 and Temperature”

Temperature Regulated Cooling Dominates Warming and Why the Earth Stopped Cooling At 15°C

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 system dominates;Continue reading “Temperature Regulated Cooling Dominates Warming and Why the Earth Stopped Cooling At 15°C”

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-termContinue reading “Holocene CO2 Variability and Underlying Trends”

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. ThisContinue reading “The Old Farmer’s Almanac Seasonal Forecasts”
