I wonder how Much of it is global warming vs other effects! Would be nice to see a even longer historical overlay of the changes. Or even have the values corrected for anomalies that are not an effect of human involvement.

Sure, there is some uncertainty. But in reality, we have a pretty complete model of physics, chemistry, geology and biology. Generally, the predictions we made 10 or 20 years ago match with what we're seeing.

So of course "science does not deal in certainties" but most of the questions are really at the second or third decimal point.

There is an excellent video by David Louapre (of Science Etonnante fame) that explains for example how our greenhouse model works. It's in French, but subtitles should do the tricks https://www.youtube.com/watch?v=ewc8FBtEKPs

You have been downvoted, but it is a good question. Hopefully it was asked in good faith ;)

Since around the 1970s, the North Sea became a few degrees warmer. Fisherman more regularly find fish and other creatures that used to be only down in France or even more south. As far as I know, we don't really know what caused this trend of the gulf stream going more up north. For all we know, it might switch back and we get the climate of Canada; winter from September until April.

Now we find out that same gulf stream is slowing down. We did not predict that and don't really know why it happens and what the consequences will be.

By the way, inside the country, water coming in from more central Europe is coming in faster in winter, causing problems, while in summer not much is coming in, causing more draught. Germany and Belgium are not prepared for this. A few years ago many people died when rivers overflowed.

From what I've read so far, we could get a nordic ice-age, because we're so dependent on that hot water and air.

In what way could this question be asked in bad faith?

[ianlevesque]

Sure yeah, or we could accept the settled science and move on to fixing the problem before the ice caps are gone and frozen methane hydrates vent from the ocean and kill much of the globe.

recent science graphics shown among experts predict 4-5 degree celsius rise in annual mean temperatures in far north Europe. From previous discussion, these numbers will change quite a lot of daily life all year.

What? Of course we should! It is of course partially caused by humanity. But it’s a common debate among researchers exactly how much the trends are affecting the changes.

[twentysix]

If history has taught us anything, the idea of "settled science" is as anti science as it comes.

[hotpotamus]

I’m pretty sure the only anomalies that have ever produced geographic temperature changes as drastic as the ones visualized are things like city-sized asteroid collisions or volcanic eruptions that blot out the sun. If you haven’t noticed any of those, then it’s probably safe to assume that approximately 100% of the effect is down to human activity.

[flerp]

That’s a faulty statement! https://climate.nasa.gov/evidence/
