It was pretty cold in Oslo and that is not very northern.

Weather =|= climate. Or one cold day doesn't make winter. Nor does one hot day make summer.

>Nor does one hot day make summer.

You're not from the UK.

Depends on your definition of summer: if you apply your expectations from an August holiday in southern France to August in the UK, that is your fault!

Buildings in northern Europe are just not built for ventilation, AC and dealing with heat. It’s not a matter of looking, that’s just not how people build here (just like people in Israel don’t build building that handle cold weather well).

I've spent few months in Andalusia and can't say their apartment buildings are better suited for heat than one I live in Poland. Yes there are more curtains and AC, but it is not related to the building, you can have them in northern apartment too.

As a person who moved to Spain (Barcelona though) from Sweden, I agree. Houses here have basically no insulation what so ever, unless they're built recently. During the summer, it's almost impossible to escape the heat unless you have AC inside. Meanwhile, in Sweden you can usually just enter any house and can be sure that there is at least is a temperature difference compared to outside just because of way better insulation.

Summary: More ice melt => More fresh water in the Atlantic => cold surface anomalies in winter => sub-polar winter storms => heatwaves in Europe in summer Mostly not predicted as models do not have fine enough grid resolution to show the movement of freshwater into the Atlantic, which happens via "narrow" channels.

Sigh, considering how bad journalists are at nuance - especially those that don't consider themselves as journalists but still wield the 4th Power of Broadcast - I can't wait (/s) until we have to "explain ourselves" about how it "contradicts" our previous meme about excess freshwater from melt being expected to at least slow down the thermohaline circulation in the North Atlantic, leading to a weaker Gulf Stream, and therefore a colder Europe (as emphasized to the point of ridiculousness in The Day After Tomorrow apocalyptic movie)... by "forgetting" the emphasis on summers.

Will at least be an opportunity to explain how Science actually works, and about chaotic systems I guess...

Still, one immediate question is how this impacts the rest of the year, since there's an (on the surface) obvious feedback loop here... (an answer to which might or might not be forthcoming...)

E.g. In Poland this has been the warmest February on record.

The mild winters are problem so: - the risk of temp drops after plants started to sprout -> bad harvests - snow is a great water reservoir, having the snow as rain leads to floods, results in lower ground water levels and droughts -> bad across the board and also impacting agriculture - the permafrost in the alps is melting -> mountains litterally fall apart And we see all that already for years now. Edit: As rain go…

- overwintering pests and diseases

Asian tiger mosquitos are evil. I shouldn't know that, having never been to Asia.

They need to start building differently.

This is already happening, but I don't know to what extent (especially over multiple countries), but we moved into our extremely well insulated house (thing 3 layers of glass) in the Netherlands mid 2020. Heating happens using a ground source + heat pump, cooling using just the ground source and passive pumping, ventilation is centralised and uses heat exchange.

During some 30/35+ waves of the last few summers we kept it below 23 degrees Celsius inside, even over many days of heat.

So, following your logic, as a German I have no right to opposse genocide? Strange logic, to say the least. And using some climate engineering fantasy from a book as a basis for discusion, really?

The issue with climate change is exactly that: change. Doesn't matter if it get colder, dryer, wetter, warmer than it used too. It is a huge undertaking to change the built environment to handle conditions that were once seen as exceptional. Houses, streets and waterways are normally replaced/adjusted on the scale of multiple decades or even centuries. Significant climate change is affecting areas everywhere on a sin…

In what used to be a snow-secure village in Bavarian alps, we had 12 degrees last week.
