Alpine winters are dying.Since the 19th century,average temperatures in these moun?tains have risen by two degrees Celsius—about twice the global average. Snow is arriving later in the season and melting sooner. The Alps as a whole have lost about a month of snow cover, according to scientists who analyzed data from more than 2,000 weather sta?tions.

To many of the 14 million people who live in one of the world's most densely populated mountain ranges,the effects are terrifying. The economy here depends on snow to lure 120 million tourists a year.

To save themselves,the people of the Alps are go?ing to lengths.An estimated 100,000 snowmaking ma?chines now power the Alpine ski industry. Beyond snow storehouses like Kitzsteinhorn,desperate locals are wrapping the ice on a few of the Alps'roughly 4,000 glaciers,to try to delay the rapid melting caused by global warming.Some of these methods are suitable and attractive;others are environmentally and economically questionable.

I was lucky enough to grow up in the Alps at a time when snow was abundant. I re?member the excitement of leaving my tiny footprints in the season's first snowfall;I remem?ber the color of my dad's cheeks as he shoveled (鏟) the house free, again and again. My parents clapped my first skis on my feet before I was three.That period turns out to be a pe?riod in history.

The pandemic shut down ski tourism across the Alps. Millions of hotel beds stayed cold.But climate change poses a more profound threat.One or two degrees of warming may not sound like much, but it can determine whether precipitation (降水) falls as snow—or rain.Turn up the temperature just a level,and snowflakes might never form.That's why the Alps are in deep trouble,says Yves Lejeune,the scientist in charge of the Col de Porte me?teorological observatory,at 4,350 feet in the western French Alps.
