Firstly there are the so called blue zones….places where longevity is the norm:
Currently in the world there are 5 areas labeled "Blue Zones".
The first is Icaria (Greece). Icaria is an island located in Greece where people have a diet rich in olive oil, red wine and home-grown fruits and vegetables.
The second is Sardinia (Italy): Ogliastra is a province in the east of Sardinia - an Italian island, this is the home of some of the world's longest-living men. Because Ogliastra is the most mountainous province in Sardinia, people here often work on farms and gardens and love to drink red wine.
Third is Okinawa (Japan): Home to the world's longest-living women, who use a lot of soy foods in their meals and regularly practice Tai Chi.
Fourth is the Nicoya Peninsula (Costa Rica). The Nicoya diet often includes beans and a type of corn tortilla. People in this area also regularly perform physically demanding jobs even in old age and have a concept of life called "plan de vida" (Often roughly translated as "Why do I stay awake?"). woke up this morning?” to reflect on your existence and create the will for a life to be enjoyed to the fullest, lived to the fullest).
Fifth is the Seventh-day Adventist Church in Loma Linda, California (USA). The Seventh-day Adventist Church is a group of very religious people who are strict vegetarians and live in tight-knit communities.

What strikes one about this is that the climates are all moderate to warm and these are places where medical help is probably less sophisticated than one would expect. But they are also places where people are active. The contrast is Northern Europe and the US where winter activity becomes harder.
So it’s hard to believe the huge NH cold zone population won’t benefit from some warming. But there are fringe Warming models out there suggesting up to 2 years of life expectancy are lost in warmer climates. It’s incredibly complex to model and most of the researchers are climate groupies
The green zones suggest there will be some benefit from projected warming. It would be refreshing to see an honest attempt to look at the benefits of a moderately warmer planet…..I suspect they will be massive.
