“Cold Outbreaks are NOT caused by Global Warming” — Dr Jay Lehr and Tom Harris

[This article was originally posted on on April 15, 2021]

“Global cooling –and global totalitarian socialism– are the catastrophes we should fear most.”


What do heat waves, floods, droughts, rising sea levels, forest fires, hurricanes, African wars, mass extinctions, disease outbreaks, and human and animal migrations from South America and the Middle East have in common? According to climate activists, they are all caused by dangerous man-made global warming. And this, in turn, is supposedly caused by rising carbon dioxide (CO2) levels resulting from our use of fossil fuels.

They might as well add alien invasions to the list, because it is all nonsense. Indeed, the climate scare industry has achieved such a level of absurdity that, on Feb 1, journalist Andrew Revkin reported in a National Geographic article that, “Many stories in recent days highlighted studies concluding that global warming is boosting the odds of cold [weather] outbreaks.”

As we delve into the realm of absurdity, however, let us not forget that, in 2011, scientists from NASA’s Planetary Science Division and Michael Mann’s Penn State University actually presented a report speculating that extraterrestrial environmentalists could be so appalled by our planet-polluting, climate-changing ways that they could view humans as a threat to the entire intergalactic ecosystem and decide to destroy humanity!

Among the most absurd of recent climate alarm statements is the one attributing recent cold spells to manmade global warming. This claim was made by University of Michigan professor emeritus of environment and sustainability Donald Scavia, who said:

“In the past there was a very strong gradient of cold air at the poles and warmer air south of the poles. That gradient kept the cold where it is … As the poles are warming faster than the rest of the planet, that gradient weakens, allowing the cold air currents to dip south.”

Dr. Tim Ball, an environmental consultant and former climatology professor at the University of Winnipeg in Manitoba, said that Scavia’s statement is “utter rubbish.” Ball explained: “It’s wrong in every aspect, from the basic assumption to the interpretation. In fact, a gradient makes things move. It doesn’t ‘keep the cold where it is.”

It’s also a mistake to think that, if human-produced CO2 is actually causing global warming, the poles will warm first: “There is no evidence of that; they just are assuming it to be the case,” Dr. Ball emphasized.

And, if the poles did warm first, Ball continued, the reduced temperature difference between the poles and lower latitude regions would reduce extreme weather events, not intensify them, as climate campaigners claim.

After all, weather and extreme weather events are driven by the temperature gradient between latitudes. A warming Arctic would result in less intense cold outbreaks and a lesser intrusion of cold arctic air colliding with warm moist air in warmer regions. Climate alarmists have their science backwards.

Ball noted that the real cause of the severe cold outbreaks in the United States is a wavy Jet Stream.

The Jet Stream –a thin band of strong winds that flow rapidly around the planet from west to east at approximately 10 km altitude– divides warm air masses, typically found at low latitudes towards the tropics, from cold air masses, usually found at high latitudes near the poles.

However, a very wavy jet stream –as we are contending with now– allows frigid Arctic air to move south to normally warmer latitudes and warm tropical air to push into Polar latitudes. The result is an increase in extreme weather events, including the cold outbreaks in the USA. It has nothing to do with global warming. In fact, the most common cause of a wavy Jet Stream is global cooling. History shows us that severe weather increases with a cooling world, not a warming one.

As to fears of more cold outbreaks due to global warming, Ball laughed, “They’re making it all up!”

Clearly, there is no end to the deceptions that the climate lobby will tell the public in order to deprive the world of reliable, inexpensive fossil fuel-based energy — the foundation of modern living standards.

Perhaps the greatest deception of all is what real scientists call cherry picking; that is, highlighting data that advance their theory and agenda, while ignoring data that do not support their politics. The below graph explains how they do it:

The overall trend of the data is obvious: as variable “A” declines, variable “B” increases.

But, if you choose only a small portion of the data (or just a few years out of 100 or 1,000), you can declare the trend to be anything you want — including having “A” stay the same as “B” increases, and even having “A” increase as “B” increases.

This is the sleight-of-hand used by global warming alarmists who want the public to believe that burning fossil fuels and increasing the atmosphere’s carbon dioxide must be stopped at all costs.

They want to run the nation and the world on expensive, inconvenient, unreliable wind and solar energy, and ignore the fact that those energy must be backed-up by dependable energy sources like fossil fuel or nuclear in order to stop the grid from collapsing. It has indeed been calculated that, were the Midwest to be dependent only on wind and solar power, at least one million people would have died of hypothermia during a recent minus-50 degrees F cold spell.

As demonstrated by Climate Change Reconsidered II: Fossil Fuels, the latest report of the Nongovernmental International Panel on Climate Change, the impact of fossil fuels (coal, oil and natural gas) has been overwhelmingly positive.

The report’s Summary for Policymakers states:

“Fossil fuels have benefited humanity by making possible the prosperity that occurred since the first Industrial Revolution … Fossil fuels also power the technologies that reduce the environmental impact of a growing human population, saving space for wildlife … Nearly all the impacts of fossil fuel use on human well-being are net positive (benefits minus costs), near zero (no net benefit or cost), or are simply unknown.”

Besides raising living standards across the world, fossil fuel use has helped elevate CO2 in our atmosphere from a level dangerously close to the point at which plants start to die to where we are today, with the Earth once again “greening,” as crops, forests and grasslands grow faster and better.

The global warming scare has never been about science, or even climate for that matter. The long-term goal of many activists is to unite the world under a single socialistic government in which there is no capitalism, no democracy and no freedom

 After all, personal freedom is fueled largely by access to affordable energy.

An intermediate goal of climate alarmism is thus to limit the amount of energy that is available and place it under tight government control. Inexpensive fossil fuels remain an obstacle to their vision, and so must be done away with entirely, climate campaigners maintain.

We must not let them succeed.

    A very cold winter might motivate a few people to stand up for fossil fuels. Maybe.

      Deb, go to and look at …wind 9000m…that is the Jetstream level. That stream is normally a easy slightly wavy line around the North and South hemisphere. What you will see is what will cause extreme weather this Winter. Snow and ice topped off with severe cold weather. I see (for SC KY) heavy snow like 1978 and temps in the minus teens F just like 1993. We got to -24°F one night. Greensburg north of us registered a record -37°F.
      Get ready and stay warm Dear.

        I’m ready: I have 8 cats and 6 raccoons to share body heat with if the power goes out.

        I wish I had what it takes to turn those raccoons into a coat, but I cannot kill anyone unless they are trying to hurt me.
        Or unless I get hungry enough, maybe…

        If I get hungry and they get hungry, it could turn into a real knock- down drag- out!

    Update on the storm in the Caribbean. I mentioned on the first of the months that God told me about a storm
    in September in a year when no other hurricanes
    formed until September.
    The storm out there is acting much like what he said. Gently tiptoeing
    through the Caribbean but exploding as it follows the warm gulf stream north to Martha’s Vineyard. Don’t worry about the immigrants
    it took them less than 24 hours to get rid of them.

    Fossil fuels are a lie. subduction is creating new oil perpetually and mammals will never outrun nature

      There is a theory that the total mass of bacteria living in microscopic cracks in rocks at depths up to 10km is greater than the total mass of life on the surface of the Earth. If this is true then it’s quite possible that when they die and start to decompose they will produce large amounts of methane (aka natural gas). This could mean that globally natural gas is being produced at a similar rate that it’s being extracted and could last more or less forever, although individual gas fields will become depleted and will have to be left alone for some time to refill.

        We need Cold Fusion. That way a small unit the size of a kitchen stove can power your home so long as you keep the deuterium tank full. And 1 cubic mile of ocean has enuf deuterium for all of Mankind for 10 yrs.
        And it replenishes CONSTANTLY.

    Curious that it is suggested that at the South Pole it is warmer further South. Of course, it was intended to say warmer towards the lower latitudes.

    It must be challenging to comprehend Earth has two hemispheres.

      “Global cooling –and global totalitarian socialism– are the catastrophes we should fear most.” JAY LEHR and TOM HARRIS obviously stole my quote from over 3 years ago… I never get no respect.

      Yuval Noah Harari says globalists have created a “technological Noah’s Ark” (transhumanism) to escape mass extinction event they’re unleashing
      – September 16, 2022
      The lead advisor to globalist kingpin Klaus Schwab says “elite” figureheads from all around the world have developed a “technological Noah’s ark” that they believe will save them from a soon-to-arrive global mass extinction event.
      Yuval Noah Harari took part in a discussion recently at the Warwick Economics Summit in Great Britain. He revealed that the globalist leaders in charge of the planet right now are planning to escape – or so they think – what is soon to come upon the world… on September 24, 2022… remember to duck, pray and cover.

        … get ready, just 7 shopping days left until September 24, 2022.

      2. Deb

        I’m shaking in my boots-esp re that Sept 16 date!

        1. Church Lady Logos

          … the date the article was printed?

        2. Church Lady Logos

          … now just 6 shopping days left until September 24, 2022.

          1. Deb

            So, what am I supposed to shop for- a T-shirt that says “I attended the end of the world, and all I got was this crummy T-shirt”?

            1. Church Lady Logos

              Buy sardines.

          2. Deb

            If I go and buy any more sardines, which I don’t really like, and the world does not crash on Sept 24, boy are you going to hear about it !!!

      3. Deb

        These guys are all grading themselves on the curve, comparing themselves to other humans and feeling ever so powerful.

        They need to be comparing themselves to God, because in the Day of His Wrath, their money and power and ” technological wonders” will crumble into dust before His judgment for what they have done.

        I would way rather be the poor little church mouse that I am than any of those “great and powerful Oz’s” like Gates, Soros, Schwab, Rothschild et al. Their end will not be pretty.

      Actually Antarctica has broken temp records two yrs in a row. Summer temps were 30-40°F colder than normal.

  5. Chris Norman

    They know that the planet is cooling and we are entering a grande solar minimum. So they use the results of that fact to push AGW.

      Hard to say if the Bible prohibits the eating of insects because of an inherent danger, or simply because it’s part of God’s plan to make a separate people of the Jews.

      The Thais eat some insects, and it seems normal to them.

      I don’t really understand this emphasis on insect-eating by the PTB. Why are they pushing it?

    1. Deb

      This may very well be the answer to my question, “Why are the PTB pushing insect-eating?” Looks like chitin (found in insects) causes allergic/inflammatory response, which then triggers all sorts of chronic diseases – arthritis, heart disease, diabetes- which then requires the use of pharmaceuticals, making certain *ssholes rich and debilitating people who might otherwise be moved to rise up in rebellion against said *sshole PTB’s.

      Well, Timmy, looks like you can’t have your pudding til you eat all your crickets.
