This is Puerto Rican erasure.

The historical existence of snow depends on where you’re talking about. Climate is changing but not every manifestation of that will cause less snow. It’s possible some places start getting more as rising temperatures create more moisture in the air in places that are historically cold and dry. For example, parts of the mountains here in Nevada had unusually high snowfall, like Lee’s Canyon While looking at (what appears to be) the historical data for the US overall doesn’t seem to show a significant deviation at a cursory glance.

Saying these things are obviously true while not bothering to check if they’re factually accurate is misrepresenting the problem and leaves openings for climate denialists to make themselves more credible. “You said snowfall was going down but it just saw record snowfall in the news!” Which is a bad argument but a convincing one to people who aren’t inclined to deal with a global apocalyptic problem.
