San Francisco Named Only U.S. City Cold Enough To Host Summer Olympics By 2085

In the wake of the 2016 Olympics, the world has already begun speculating on locations for future Games. According to UK medical journal The Lancet, global warming will heat up most of the Northern Hemisphere too much to hold the Summer Olympics by 2085. The research named eight cities, outside of Western Europe, that would still be viable for the Olympics by that time. In North America, that list is even shorter, including only Calgary, Vancouver and San Francisco.


This news recalls that famous quote, often attributed to Mark Twain: ‘The coldest winter I ever spent was a summer in San Francisco.’ This time, San Franciscans may have a reason to be grateful for their year-round temperate weather, keeping summers extra cool. According to Diana Henderson, a forecaster with the National Weather Service Forecast Office for the San Francisco Bay Area, San Francisco’s cold weather is due to the city’s location between the Pacific Ocean and the Central Valley. Working with Henderson, KQED News writes, ‘To the west, the marine layer sits above the cold Pacific. To the east, heat in the valley creates thinner air and low pressure. The valley becomes like a vacuum that wants to be filled by the heavier marine layer. It pulls that layer over San Francisco, which typically makes the city cooler than other parts of California – and the country – in the summer.’

This also gives San Franciscan’s a reason to be grateful for their city’s famous, chronic layer of fog, affectionately dubbed with the name Karl. So next time you’re shivering and feeling resentful of that constant overcast gloom, curl up in a blanket instead and thank your lucky stars that your city will still be in livable conditions by the final quarter of this century.
