Olympic town warms up as climate change puts games on thin ice

Olympic fans came to Cortina with heavy winter coats and gloves. Those coats were unzipped Sunday and gloves pocketed as snow melted from rooftops — signs of a warming world.

“I definitely thought we’d be wearing all the layers,” said Jay Tucker, who came from Virginia to cheer on Team USA and bought hand warmers and heated socks in preparation. “I don’t even have gloves on.”

The timing of winter, the amount of snowfall and temperatures are all less reliable and less predictable because Earth is warming at a record rate, said Shel Winkley, a Climate Central meteorologist. This poses a growing and significant challenge for organizers of winter sports; The International Olympic Committee said last week it could move up the start date for future Winter Games to January from February because of rising temperatures.

While the beginning of the 2026 Olympic Winter Games in Cortina truly had a wintry feel, as the town was blanketed in heavy snow. The temperature reached about 40 degrees Fahrenheit (4.5 degrees Celsius) Sunday afternoon. It felt hotter in the sun.

This type of February “warmth” for Cortina is made at least three times more likely due to climate change, Winkley said. In the 70 years since Cortina first held the Winter Games, February temperatures there have climbed 6.4 degrees Fahrenheit (3.6 degrees Celsius), he added.

For the Milan Cortina Games, there’s an added layer of complexity. It’s the most spread-out Winter Games in history, so Olympic venues are in localities with very different weather conditions. Bormio and Livigno, for example, are less than an hour apart by car, but they are separated by a high mountain pass that can divide the two places climatically.

The organizing committee is working closely with four regional and provincial public weather agencies. It has positioned weather sensors at strategic points for the competitions, including close to the ski jumping ramps, along the Alpine skiing tracks and at the biathlon shooting range.

Where automatic stations cannot collect everything of interest, the committee has observers — “scientists of the snow”— from the agencies ready to collect data, according to Matteo Pasotti, a weather specialist for the organizing committee.

The hope? Clear skies, light winds and low temperatures on race days to ensure good visibility and preserve the snow layer.

The reality: “It’s actually pretty warm out. We expected it to be a lot colder,” said Karli Poliziani, an American who lives in Milan. Poliziani was in Cortina with her father, who considered going out Sunday in just a sweatshirt.

And forecasts indicate that more days with above-average temperatures lie ahead for the Olympic competitions, Pasotti said.

Weather plays a critical role in the smooth running and safety of winter sports competitions, according to Filippo Bazzanella, head of sport services and planning for the organizing committee. High temperatures can impact the snow layer on Alpine skiing courses and visibility is essential. Humidity and high temperatures can affect the quality of the ice at indoor arenas and sliding centers, too.

Visibility and wind are the two factors most likely to cause changes to the competition schedule, Bazzanella added. JENNIFER McDERMOTT, CORTINA D’AMPEZZO, MDT/AP
