Science of Heat Waves Reveals Blaming CO2 is a Scam!

With a disproportionate focus on the greenhouse effect and fossil fuels, most people are totally unaware that the earth’s surface is cooled primarily by convection currents carrying warm buoyant air up and away. Indeed, with water vapor and CO2 making the lower 1000 meters of the atmosphere opaque to most escaping infrared, thus preventing radiative cooling, the earth’s surface only cools sufficiently via convection. All honest scientists know heatwaves are caused by suppressed convection.
Graphic A shows a typical heat dome resulting from a high-pressure system that causes sinking air that suppresses rising convection. Air sinking from the colder upper atmosphere is dry and thus maintains clear skies that increase solar heating. A warmer earth surface from climate change should cause rising air, so what causes sinking air?
In the tropics, the greatest warming happens around the equator and that draws in air from the northern and southern hemisphere. Where that surface air converges (aka Intertropical Convergence Zone) air is forced upwards. What goes up must come down, and to maintain balance the air sinks around 30 degrees north and south, forming high pressure systems over the desert latitudes (Hadley Circulation). Outside the tropics the main driver of high-pressure systems is the convergence of upper atmosphere winds in wavy jet streams.
