I live in Norway now and I can see a lot of the changes you mention Correlation does not imply causation One may observe change, but attributing that change one way, or another is a different matter. 500 years is insignificant when it comes to the planet, the sun, and other factors that cand cause variance over longer spans of time. I do not think we know enough yet about those systems to say with 100% certainly what the cause is, esp. when explaining it with extremely short-term attributes. When science has more than one theory for something you can elect to pick one of them, a couple other, or none ago with that based on your own research, the media you chose to consume and your background and friends. Most science these days is so complicated that it is always based on a choice to believe. Unless you PhD in many fields there is no way ou can know for sure if something is correct. Even if someone gives you nice diagrams. Can you really understand and repeat the diagrams? I have never seen an electron. Nor have I never seen an atom. And I certainly haves never seen a quark or a boson, or a gravition (that last one nobody has seen yet). I have seen diagrams and I have seen simplified forumulas that even I can understand. Dark matter is one hypothesis I hope is replaced by something more elegant. I cant see, scientist cant see it. You elect if you believe in it or not. (There has been some recent proof based on gravitational measurements and there have been a theory now that dark matter is just all the matter that never formed into planets) Even in my own field of study of computer science, there are many things I do not understand now, and really grasping it would require another doctorate. All that long stuff just to say that for a lot of science for the vast majority it is a matter of belief. Now if I am not sure if all the changes in climate can be blamed on human impact. I do not think that is relevant to whether we need to cut emissions and pollution. We need to do that no matter what. If 30 years in the future, if I am still alive, and scientist puzzle out that based on new theories, models and evidence the majority of changes had nothing to with human interference we will be much better off in a cleaner and less polluted world Is burning coal casuing a lot of health issues now? Yes it is. Then we stop doing that. Is breathing air filled with polluted smog or car emissions pleasant and good for you? No, we need to do something about it. Almost all issues that people want to change that climate scientists may or may not be climate change, but you can break it down further to arrive at the exact same conclusions for nearly all of it. It is a win / win no matter what.
