One thing that I see time and again that makes me sigh in exasperation is when someone makes a post or comment about some record low temperature at some place and accompanies it with a snarky comment about climate change. You know, as if it were evidence against climate change.
This always makes me facepalm because it's something that the climate science predicts will happen more and more often, not something that goes against their predictions. This is essentially using a correct prediction of climate science and trying to use it against that very climate science.
Climate science predicts that as global average temperature goes up, climate extremes will get accentuated more and more. In other words, dry areas will become drier, rainy areas will become rainier, hot areas will see record-high heat waves, and very cold areas will see record low temperatures, time and again.
Thus, when a particularly cold area of the world, like many parts of Siberia, sees an all-time record low temperature one morning, and this starts happening more and more often, that's actually a correct prediction of climate science, not evidence against it.
The thing is, however, that the global average temperature is going up, even though the extremes get accentuated.
Global warming is not measured by an individual measurement made one morning at one particular place. It's measured as the average over the entire planet over the entire year. Thus it doesn't matter if a record low temperature happens one day at one place, because that only contributes a bit to the world-wide average. Which is going up. It's compensated by other places becoming warmer and warmer over the years (and also by record high temperatures at many places).
It's curious how these "skeptics" always love to gloat about record low temperatures, or even just unusually low temperatures, but they keep oddly quiet about record high temperatures at other places (and will just come up with excuses when pointed out to them. For some reason record low temperatures are clear evidence, but record high temperatures are not. Double standards much?)
