DC winter disproves global warming?
The short answer to the above question: No. Nor does a a single warm winter mean global warming is valid either. The trend of average temperatures over time is much more informative and useful. (Hint: That’s going up.)
The long answer is more interesting. Climate change - a better term than global warming - is affected by the movement of heat and cold through the atmosphere. When the planet averages warmer, not all areas are made equally warmer. The areas with more sun - like the tropics - get warmer proportionally than the poles do. (Although the poles do also warm some.)
But there’s a flow of heat from warmer areas (tropics) to colder areas (poles) through areas in between the two (like temperate areas like Washington DC). If there’s more heat to move, it has to move faster. The way that that heat moves is through broad atmospheric masses of air swirling along. A shorter term for that is “storms”.
So the higher the average temperature on earth, the more extreme the weather since the more extreme the storms. There are wider swings of temperature and weather at any given point over time. Washington DC area’s weather doesn’t mean that climate change is invalid. But basically, extreme weather IS climate change.
Senators DeMint and Inhofe as well as others either are being ignorant, stupid, or are being demagogues. Nothing new there.
