Canary Islands are part of Spain and probably unaffected from climate change - we have 19-22°C all year round. If it raises to 25° still pretty livable.

No place is unaffected.What?
But yeah, if you come with kids, factor in private schools. The public system here is broken. As for internet, I pay less than 10€/month for 500Mbit fibre - I couldn't even get that in Germany and if could it would be north of 80€.
Or you are a doctor, a teacher, an architect or a bananas farmer. Some of the richest families in the islands just export/import commodities since three generations.
A warmer ocean means much bigger storms over the islands. This has both positive and negative aspects.

I would also never use the word "solve", as this is just for human usage. The ecosystems themselves are irreversibly destroyed.
