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.

It isn't that simple, Canary Islands already counts with 2.2 million + tourists people and the fresh water is a highly risk resource even when desalinization plants are widespread, the groundwater aquifers are severely compromised. The mild weather heavily depends on the trade winds. But models predict that due to fact of being so close to Africa heat waves are prone to be more and more frequent compromising the water resources.

    and probably unaffected from climate change

Islands are extremely vulnerable to climate change all over, as they are completely dependent in near-term precipitation for all their water (no rivers, no aquifers).
