Wayward Jet Makes Late Season Weather More..uh.. Interesting

November 4, 2022

Weather is a freaky thing, and nobody knows for sure what’s going to happen today, but that sharp demarcation across the middle of North America indicates the kind of loopy, extreme jet stream that scientists say is becoming more common, and related to climate change. (compare temperature anomalies above to path of jet stream, below)
This is the topic of my upcoming video, and maybe several, as I’ve spent time talking to scientists who have developed and championed this idea, Jennifer Francis, Kai Kornhuber of Columbia U, and Judah Cohen at MIT.

In late 2021, we saw extreme examples of what this means in the real world, with the extreme tornado outbreak across Missouri, Kentucky and Tennessee on December 10, and 5 days later the unprecedented “Christmas Derecho” that set records across the upper midwest.
Today, some kind of severe weather is expected in the southern plains area, generally, too early to tell exactly what. Not unprecedented in November, but perhaps an indicator of what will become more common? As jet stream undulations become more extreme, and the Gulf of Mexico stays warmer, longer into the cold season, big masses of warm and cold air are going to be crashing into each other with increasing frequency. Given what we’ve already seen in October of this year, I suspect this won’t be the last day of unstable weather we’ll see this year.

    Another warning (which will get little to no attention):

    The “world’s largest industry” is destroying the planet. Some of the largest corporate contributors to this realize it, but they too are trapped in the capitalist model of fierce competition. Politically, we can’t seem to realize that capitalism, while raising the standard of living for billions, also is a massively resource wasteful economic system that puts all priority on short-term profits over long-term sustainability.

      Both New Zealand and Denmark announced ‘environmental taxes’ on agriculture last week. First thought is wtf. Other thoughts will take some thought.

      The giant anoxic “dead zone” in the northern Gulf of Mexico from US fertilizer runoff has been showing up for decades now, but there’s no legal link between any one farm’s fertilizer runoff and algae blooms.

      [Note that lawns and landscapes are much more heavily overfertilized than crops are, but there’s much, much more land under cultivation for crops. Urban/suburban fertilizer runoff shows up much readily in inlocal town creeks, ponds and rivers.]

      Time to pull out Tom Toro’s cartoon again:
