No Tricks Zone By Kenneth Richard on 27. January 2022 Media outlets are pressured by “green groups” to opportunistically claim every extreme weather event – including the ensuing damage – is caused by human greenhouse gas emissions. In recent decades there has been a deintensification of extreme weather (precipitation) events. Image Source: Koutsoyiannis, 2020 Deaths and property losses from extreme weather events have also been on the decline in recent decades (Broccard, 2021). Image Source: Broccard, 2021 Models cannot simulate extreme events and mechanistically attribute them to human activity (Bellprat and Doblas-Reyes, 2016).

Climate Etc by Judith Curry | Dec. 16, 2021 Politics versus the data versus communicating science. On December 10 and 11, a catastrophic tornado outbreak slammed the Mississippi Valley, with catastrophic impacts particularly in Kentucky. One tornadic storm traveled more than 200 miles, and more than 100 people may have died. An excellent overview of the storm was written by Bob Henson [link]. Preliminary analysis indicates that the maximum tornado strength was EF4, with winds estimated as high as 190 mph. Tornadoes and global warming The links between tornadoes and climate change are more nuanced than for phenomena such as …

Heartland By H. Sterling Burnett | Dec. 16, 2021 Climate Change Weekly #420 In the aftermath of the terrible and deadly multiple tornado strikes across several states on December 10, President Joe Biden and the woke parrots on his climate team wasted no time in linking the recent tornado disaster to climate change. In his Saturday morning media briefing discussing the tragedy, here’s how Biden responded to a question about whether the timing and severity of the tornadoes were due to climate change: Well, all that I know is that the intensity of the weather across the board has some …

By Clyde Spencer | Dec. 16, 2021 PARTY TIME Imagine that someone decides to throw a theme party and the theme they choose is ‘blue.’  They invite 10 of their friends and ask each of them to bring a plastic baggie filled with blue M&Ms™ candies.  When the guests arrive, they empty their baggies into an empty punchbowl.  The host(ess) places the filled bowl on the hors d’oeuvres table.  Assuming that each of the guests brings on average about 100 pieces, there will be about 1,000 pieces total.  Throughout the evening, the guests partake sparingly of the contents of the …

By Jim Steele | Dec. 13, 2021 The video examines the weather dynamics that that led to the outbreak of tornadoes devastating Kentucky and the Mississippi River Valley region. Unusual cold, not warmth, plus the North Atlantic Oscillation and Bermuda High Pressure system are shown to be the main natural dynamics generating the storms and refutes the ambulance-chasing climate change journalists that fear-monger attribution to climate change A transcript of video is available at https://perhapsallnatural.blogspot.com/2021/12/blog-post.html Jim Steele is Director emeritus of San Francisco State University’s Sierra Nevada Field Campus, authored Landscapes and Cycles: An Environmentalist’s Journey to Climate Skepticism, and …

Manhattan Contrarian By Francis Menton | November 27, 2021 Is President Biden doing anything right? To this observer, his policies range from at best merely incompetent, to at worst malicious hatred of the country and people whose interests he was elected to advance. Somewhere in between those two extremes we have Biden’s energy policy. In this arena, appropriate adjectives would be inconsistent, incoherent, and destructive. Don’t even attempt to make sense of it. To summarize in one word, it is complete madness. I’m old enough to remember the 1970s, and the two “oil shocks” that occurred during that decade. A …

By Leif Svalgaard | Nov. 23, 2021 In a talk featured in our Monday Weekly Climate and News Roundup at the 14th International Conference on Climate Change Willie Soon [at time 26:49] took me, (Svalgaard) to task for arguing that there has not been any trend in solar activity the past 300+ years. He showed their new reconstruction of solar activity as support for his criticism: Here is the video cued up. I also show the reconstruction by me and Ken Schatten [2016, https://svalgaard.leif.org/research/Reconstruction-of-Group-Number-1610-2015.pdf ]. To my eye there is no difference between our reconstruction and theirs [based on Machine …

Eureka Alert Nov. 12, 2021 Researchers find repeated link between volcanic eruptions and dynastic collapse in China’s Imperial Era Trinity College Dublin Volcanic eruptions may have triggered abrupt climate changes contributing to the repeated collapse of Chinese dynasties over the past 2,000 years, according to new research published today [Thursday, 11 November 2021]. The study also illustrates how volcanic eruptions can profoundly impact vulnerable or unstable regions and highlights the need to prepare for future eruptions. The research, which combines historical evidence with polar ice-core records of volcanic eruptions, was led jointly by historians and environmental scientists from Trinity College …
