Mann vs. Scientific Method
Michael Mann on Trial
Dr. Michael Mann, formerly of Penn State, is the creator of the highly flawed temperature "hockey stick" that purportedly shows unusual and unprecedented warming over the last 120 years. He then directly links increasing CO2 to this 20th century warming.
Mann's reconstruction of historic temperatures eradicated the well-documented Medieval Warm Period (A.D. 850-1250) and the disastrous cold of the Little Ice Age (A.D. 1250-1850). The hockey stick graph has been thoroughly debunked as using incorrect proxies, fabricated data and questionable statistical methods.
Twelve years ago, acerbic commentator Mark Steyn called his work "fraudulent" and was promptly sued by the professor for libel. The trial finally began last week.
CO2 Coalition member John Droz (you may remember that he single-handedly got the Scientific Method added to the North Carolina education standards in 2023) has published an important story here on the Scientific Method and the trial.
It turns out that the judge rejected all but one of Mann's experts, ruling that they were inadmissible because they failed to prove that they had followed the Scientific Method. Read John's full reporting here.
Greening of Earth Continues Unabated.
So, What about the Global Drought?
If you are a follower of the CO2 Coalition's work, you are well aware of our promotion of the huge benefits of increasing atmospheric CO2 to global increases in vegetation (greening).
The most recent study documented that globally "55.15% of areas are greening at an accelerated rate." Yet, the authors had to bend a knee to the climate establishment by claiming that this was occurring "despite increased drought since 2000." Is that the case? Is drought increasing? The facts say otherwise.
Below is a summary of land-based weather stations worldwide showing a significant increase in precipitation, hardly what is expected if global drought were increasing.
Vicente-Serrano (2022) reviewed global drought from the Climatic Research Unit and the Global Precipitation Climatology Center covering the period from 1950 to 2020. They found that both data sets show a significant decline in global drought. The graphs below identify the level of drought as Mild (green), Moderate (red) and Severe (dark red).
Astonishing that U Penn retains this charlatan!
