Some good news. (and some propaganda):
The ozone layer is healing and redirecting wind flows around the globe
The hole in the ozone layer above Antarctica is continuing to recover and it is leading to changes in atmospheric circulation – the flow of air over Earth’s surface that causes winds.
Using data from satellite observations and climate simulations, Antara Banerjee at the University of Colorado Boulder and her colleagues modelled changing wind patterns related to the layer’s recovery. Its healing is largely thanks to the Montreal Protocol agreed internationally in 1987, which banned the production of ozone-depleting substances.
Before 2000, a belt of air currents called the mid-latitude jet stream in the southern hemisphere had been gradually shifting towards the South Pole. Another tropical jet stream called the Hadley cell, responsible for trade winds, tropical rain-belts, hurricanes and subtropical deserts, had been getting wider.
Banerjee and her team found that both of these trends stopped and began to reverse slightly in 2000. This change couldn’t be explained by random fluctuations in climate, and Banerjee says they are a direct effect of the recovering ozone layer.
Martin comments: I wondered what became of the old “Hole in the Ozone layer” emergency. Unfortunately the article continues with the inevitable party pooping in the form of the Climate Emergency narrative that has overshadowed the ozone hole emergency. Oh well, this IS a mainstream scientific publication I guess.
But here’s a thought for you. Maybe its the changes in weather patterns due to the healing ozone layer that’s causing the unusual weather blamed on CO2 induced Climate Change? So maybe it’s “man made” in a different sense: A reduction in CFCs returning Earth to equilibrium? Seems logical to me.
