(1,716 posts)I've noticed that myself. To me, the physics are the most compelling. We've known for centuries that increased CO2 will cause warming due to the greenhouse effect. Fourier was the first to theorize about it, and others have proved it centuries ago.
Now we have new mathematics that did not exist only a couple of decades ago, and we know how to look at dynamic systems differently. The relationship between weather and climate has a fractal quality to it. Lorenz attractors explain the cold extremes that accompany the other changes. To me, the statistics and the anecdotal stuff just verifies the physics.
People do look at this stuff differently. The generally accepted theory of warming and climate change is that when heat is added to the system it will become more chaotic, meaning that the attractors will move further from the center.
The extremes will move farther apart such that weather can become both hotter AND colder.
This is what the models predict, and this is exactly what the data is showing. When you freeze the animation in the NASA link it is clear that the spread is also widening as the data shifts to the right over time:

Note that this illustration just includes the "high temperature" events that have been recorded. Under the theory, the "cold temperature" events should show a similar pattern, only as a mirror image. I haven't seen such an animation, but it would be right on point to the issue you raised.
