Where climate is already moving people and capital

France and Spain: a measurable shift away from heat

A 2026 survey by French listings platform Leboncoin, taken during the country's second major heatwave of the year, found that a third of respondents now factor a region's future heat exposure into where they choose to live. A quarter said they would consider buying a second home in a cooler region if summers at their current address keep becoming unbearable.

Spain shows the same pattern. Economists at Madrid's Universidad Complutense found that each additional day above 35°C measurably lowers house prices and rents in the affected region the following year — while pushing prices up in cooler regions further away. Their estimate: every day over 35°C reduces local house prices by about 0.08% and rents by 0.15%; in cooler regions, prices rise roughly 0.16% and rents 0.3% in response.

Italy doesn't fit the pattern — and that's the interesting part

If the France/Spain mechanism held everywhere, Italy's north — Lombardy, Veneto, Emilia-Romagna, the region this site's country comparison identifies as carrying the highest combined climate and fiscal risk of any region covered here — should be losing ground, not gaining it. It isn't. The north continues to concentrate both population and economic growth relative to the south, despite carrying the highest hazard exposure of any region measured on this site's city-level map.

The likely reason: in France and Spain, north and south are economically closer to comparable, so climate can tip the balance. In Italy, the north's industrial and employment advantage over the south is so large that heat and flood risk haven't been enough to offset it — yet. Whether that holds as damages climb is an open question, not a settled one.

Global reinsurance capital is abundant. That doesn't mean your street is insurable.

It's tempting to read soft global reinsurance pricing as good news for climate risk — plenty of capital chasing business, premiums under pressure. But abundant capital at the top of the market says nothing about whether any specific address at the bottom can still get covered. The two move independently, and Europe already has its own version of the Florida or California pattern, where entire zones become effectively uninsurable regardless of how much capital the industry holds overall.

That's the mechanism worth watching, not the headline reinsurance figures: a soft market and a stubbornly high, unmoving protection gap aren't a contradiction. They're the same thing seen from two different heights. Capital isn't retreating from climate risk in aggregate — it's sorting, address by address, into what's still insurable and what no longer is. The places that fail that sort don't show up in reinsurance earnings calls. They show up as homeowners who can't get a quote.
