Shortly after Thanksgiving, (like about 24 hours) I briefly hoped the USA might be on the road to recovery as far as racial issues and basic justice are concerned despite the odds. Then, whammo the new COVID-19 Omicron Variant appeared packing a double punch to all of our guts in addition to the nazi GOP giving Biden a very difficult time. Down here, it has been a complete mess and I will return to that.
Meanwhile the tornadoes, why are these things so unbelievable? I am of the opinion that Joe Biden needs to move his ass on this and send in the freakin Marines, set up immediate not tomorrow shelters, food and medical assistance and whatever these people need; and stop being so nice about it Joe, just do it. We do this for countries all over the world who are in dire need after chaos and turmoil and disaster. What makes the American people so different?
Double meanwhile, I'm back on the damn tramadol and can barely walk so it's been weird. We managed to put two little tiny trees up, one in the living room and one in the piano room...but Totsie and Rubio think these are new toys and they keep knocking them down, so right now they look pretty haggard. I'm not baking this year because I cannot stand but if you are in a pickle go to Pasta Cheese in New York, they have the yummiest of yummies and full legs of lamb. Tell Andrew Maggie sent you.
Hope you don't have a leaky roof - we are expecting heavy rains starting Tuesday afternoon and BTW, get your damn booster shots.
I'll be back with highlights on Mexico, and it is not good news. Frightful warnings coming from the State Department and the CDC re Mexico inclusive of Baja California.

Why Biden Is Likely Right That the Climate Emergency Is Partly To Blame For Massive Tornadoes
"Ann Arbor (Informed Comment) – The string of horrific tornadoes generated by unrelenting thunderstorms over hundreds of miles in the southeast and midwest of the US has likely left over a hundred dead, and has wiped out portions of small towns.
As with any extreme weather event, it is natural to ask whether it is related to human-caused climate change, since we are pumping so much heat-trapping carbon dioxide into the atmosphere that it is rapidly changing our climate. This question came to President Biden in a news conference in which he characterized the massive string of tornadoes as an unimaginable tragedy:
- “Q Mr. President, does this say anything to you about climate change? Is this — or do you conclude that these storms and the intensity has to do with climate change?
THE PRESIDENT: Well, all that I know is that the intensity of the weather across the board has some impact as a consequence of the warming of the planet and the climate change.
The specific impact on these specific storms, I can’t say at this point. I’m going to be asking the EPA and others to take a look at that. But the fact is that we all know everything is more intense when the climate is warming — everything. And, obviously, it has some impact here, but I can’t give you a — a quantitative read on that.”
Biden’s answer was careful and nuanced. That didn’t stop the climate denialists from jumping all over him. But he simply delivered the prevailing scientific consensus. Hurricanes in the Gulf of Mexico are more intense because of the climate emergency. The mega-drought in the southwest is more intense because of man-made global heating. About those there isn’t any doubt. Whether the carbon dioxide in the atmosphere is making tornadoes more intense is less clear, but there is some scientific evidence that it is.
Samuel J. Childs et al. point out in Weather, Climate, and Society that “A combination of favorable environmental ingredients must exist in sufficient quantities for the formation of a thunderstorm capable of producing large hail and tornadoes. These ingredients most foundationally include instability, vertical wind shear, moisture, and a lifting mechanism.” They predict at least one extra tornado per year by the end of this century in Colorado.
The eminent climate scientist Michael E. Mann at Penn State points out that the Gulf of Mexico has already heated up substantially over the past century, which provides the moisture to the lower atmosphere needed for thunderstorms in the southeast. It also provides more heat. More moisture and heat create the conditions for convection. The other ingredient is wind shear. Man-made climate change has pushed the jet stream, which flows west to east, further south occasionally. Where you have a westerly wind at lower altitudes, it will interact with the jet stream going the other way, producing wind shear and potentially a tornado. As Mann admits, climate models often predict an over-all decrease in shear. But, he says, there will be days where extra heat, moisture and shear do combine to create tornadoes, and they will be doozies. That is, you may get fewer but vastly more powerful tornadoes.
Childs and his colleagues say that over the next 80 years, “Changes in hazard frequency and spatial distribution may amplify human exposure up to 117% for tornadoes.” They point out that tornadoes and hail storms are among the most costly and devastating natural disasters in the U.S. In 2018, for instance, 50% of billion-dollar weather catastrophes were generated by tornadoes and hail storms.
Mateusz Taszarek et al. write in The Bulletin of the American Meteorological Society , “Increases to the frequency and intensity of severe thunderstorms are an expected outcome of anthropogenic warming over North America and Europe by 2100 (Diffenbaugh et al. 2013; Hoogewind et al. 2017; Allen 2018; Rädler et al. 2019; Trapp et al. 2019).”
Since tornadoes depend on the amount of moisture in the air and on the formation of a thunderstorm, models suggest that there will be more and more powerful tornadoes in some parts of the country, such as the southeast. Taszarek and his colleagues see some indication that the hurricane season in the southeast will switch from summer (when wind shear may be reduced by the hot air) to winter. In contrast, the western states will get less precipitation, and so may have fewer tornadoes.
So is global heating causing more or worse tornadoes? Professor Michael E. Mann thinks there is evidence for it, and he’s the one I trust on these issues."
And of course, we trust & love Juan Cole.
At some point, I'll be back with Mexico. Shite, the trees just went down again ! Seriously. (;
