Climate change will go both ways, cold bouts will be colder and warm bouts will be warmer. Cold will be less present on average because of rising global temps but extreme weather patterns will be more common. I assume that's what's happening on your side of the world.
Yep. More energy in the atmosphere doesn't necessarily mean higher temperatures. As a general trend sure. But it will mean more energetic weather patterns. More "outliers" and wild swings stressing everything.
Pretty sure they are referring to average annual temperature. The winters may get colder in some areas, but the summers are getting hotter everywhere, and to a bigger degree. So the average temperature will continue to trend up.
It's just not accurate though. Again, most scientists have parts of the world getting INSANELY cold and some parts getting INSANELY hot. But it will not be an even distribution.
Overall heat going up? I agree. But the wording of the article isn't theoretically correct.
