Hold On To Your Hat

As you can tell by the name, extreme weather is rare on our planet but when it does occur it illustrates just what the climate is capable of at its worst and since Earth’s climate is rapidly warming the range of possible weather extremes is changing.
Environmental Scientists define climate as the average (or normal) temperature over a 30 year period and updated every 10 years to know what to expect from a certain location and the difference between each successive 30-year climate period serves as a very literal record of climate change.
They have noted that global average temperatures have increased at around 0.2°C per decade over the past 30 years, meaning that the global climate of 1994 was around 0.6°C cooler than that today in 2024 and with a climate that is still warning, it means that we have not necessarily experienced the extremes that modern-day atmospheric and oceanic warmth can produce.
Extreme weather events require a combination of things, the main driver for most of them is warmer air as warmer air holds more moisture hence the floods and stronger hurricanes and the pollution in the atmosphere acts as a blanket to to stop heat escaping into Space so we get the heatwaves, the highest ever day recorded on Earth was July 21st 2024 and that record was broken on July 22nd, the very next day.
As there is a bit of lag of several decades between the pollution hitting the atmosphere and the events on the Earth, the true impact of global warming is only evident after several decades so we are in effect reaping the result of what we did with amazing stupidity in the 1990's.
As we have continued to foolishly throw Carbon and other pollutants into the atmosphere on a grand scale since then, the extreme weather with droughts, floods, hurricanes and high temperatures are expected to get worse and more frequent so if we think we have got away with it for now,  hold on to your hat because it will get much worse.
