Occasional Thoughts on Climate Change

So great to see young professional Meteorologists getting time on major networks to help start to turn the tide on the old climate alarmist fake narratives on simple cyclical weather events!!

 

 Hey Chesco,

 Maybe so. That was a disaster waiting to happen even without CC. We’ll never know for sure about the possible influence of CC on this terrible incident as well as on many other specific incidents. But CC/GW has meant ~ a 7% increase in moisture held in the air per degree C increase. So, CC does make these incidents of very heavy rains within a fairly short period more frequent overall worldwide than before.

 Tropical systems, themselves, have on average gotten slightly wetter. Another thing CC has apparently caused is a slight slowdown of average steering winds due to a lowered contrast of the temperature gradient between the tropics and Arctic. Thus, the slightly slower avg movement of slightly wetter tropical systems means more frequent extreme rainfall events from tropical systems.

Yes, climate science predicted decades ago that the increase in precipitation due to climate change would be focused in the heaviest events and that is exactly what we are seeing. Extreme rain events are increasing much faster than precipitation as a whole. Climate change doesn't cause any one single event; but it makes individual cases worse and extreme events much more likely.
