How climate change could affect your favorite ski resorts

Ben Geman, author of Generate

A new analysis by the Climate Impact Lab explores how global warming will hurt skiing opportunities in the U.S. It looks at how some major ski towns will see fewer below-freezing days in decades ahead under different emissions levels.

  • The chart above is reconstructed from their analysis of below-freezing days under of a "moderate" emissions scenario that would prevent runaway warming, but likely would not hold the rise below two degrees Celsius compared to preindustrial levels.
  • Why it matters: "As the climate continues to warm, the number of days that can support snowfall are expected to decrease, and ski resort towns could lose valuable tourism traffic," states the Climate Impact Lab, a collaboration between scientists, economists and other experts.

More from the report:

  • "Average snowfall is influenced by a resort’s elevation and the frequency of winter storms and precipitation. But, it’s just not going to snow if it’s warm outside — days below the freezing temperature of 32°F signal whether a resort town can potentially support snowfall for ski days."
  • "Making snow doesn’t get resorts off the hook either. The ideal temperature for artificial snowmaking is an even colder 28°F, dependent on humidity.

As is often the case, the staggering job losses in the coronavirus-driven recession have been worse for black workers.

By the numbers: According to a report from the Economic Policy Institute, titled "Racism and economic inequality have predisposed black workers to be most hurt by coronavirus pandemic," more than 1 in 6 black workers lost their jobs between February and April.

The CBO released projections on Monday for U.S. nominal GDP to be lower by $15.7 trillion over the next decade than its estimate in January as a result of the coronavirus pandemic.

What they're saying: It predicts that when adjusted for inflation GDP will be $7.9 trillion lower over the next decade and down by $790 billion in the second quarter of this year — a 37.7% quarterly contraction.
