> The natural world doesn't always have the ability to adjust; lots of habits are suffering and species are going extinct. To me this is the much bigger issue than us humans adapting. For us to adapt it demands a lot of labour, and associated costs, it will make life harder but it's doable. Nature doesn't have this ability, animals can't get together in an assembly and find technological fixes to support them living…

Precisely this. Earth's 'normal' extinction rate is often thought to be somewhere between 0.1 and 1 species per 10,000 species per 100 years. A mass extinction event is when species vanish much faster than they are replaced. This is usually defined as about 75% of the world's species being lost in a short period of geological time - less than 2.8 million years. The current rate of extinction is between 100 and 1,000…

Yes, but mass extinction is the result of our greater land usage and resource overexploitation, not climate change (in that it would be happening even if climate change was not).

This also makes it harder for many species to adjust to climate change and habitat loss as it is much harder for them to migrate.

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…

This sounds great for GDP!

It’s not. Projections say that global gdp will shrink 18% by 2050 because of climate change [1].

Sufficient impact to require rebuilding houses or other buildings on a single decade scale?

I cannot see that sort of rapid rebuilding anywhere I know. I live in a house that is about 60 years old. I have friends who live in houses centuries old. Not come across anyone who needs to change very much to cope with climate change, apart from things to reduce emissions (mostly installing heat pumps can be difficult)

The built environment also needs to handle a lot of variation anyway.

I can certainly see a drastic impact in some places: low lying land (I would be very worried if I was Dutch or Maldivian. I might be quite worried if I was living in Norfolk) , but its not everywhere.

That seems mostly to be talking about rising sea levels etc.

I read GP as talking about the positive impact on GDP of rebuilding, and with the intent of pointing out that GDP is a flawed metric.

I think the key part is reminding people that it’ll be worse if we don’t act. The work of adapting won’t be cheap but it’s positive work in the right direction, boosting GDP when it would otherwise be falling chaotically.

So.. as an individual living in the northen part of Europe, can I expect a nice summer then?

If by "nice" you mean the usual 20°C most of the time but with regular heat waves of 35-40°C from May to September, sure!

What do you consider to be north?

So, as the nordic countries have experienced a cold winter this year, we are destined for a hot summer in europe?

Besides the very northern parts it hasn't been cold. Spring flowers bloomed last week in Denmark.

Stockholm was cold this winter and I would not say we are very northern.

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.

That applies in both directions and that was a response to someone saying it was warm in Copenhagen. I definitely do not doubt climate change but a warn winter in Copenhagen or a cold one in Oslo/Stockholm isn't climate, that is weather.
