Even With a Snowy Break, The Heat is on This Winter

Despite the snow that fell over much of the Northeast late this week, the winter has been warmer than normal for much of the country, in line with broader warming trends. After all, just ahead of that storm, temperatures had soared into the 60s as far north as New York City. The heavy snow even paradoxically fits with what is expected in a warming

Snowfall Totals Are Changing Across the U.S.

As the world warms, the overall area of North America covered by snow is decreasing. One reason is that an increasing percentage of winter precipitation is falling as rain instead of snow in many locations. A Climate Central report found that between sea level and 5,000 feet in elevation, a smaller percentage of winter precipitation is falling as s

Fewer Days Below 32°F

Warmer winters may sound great at first — fewer icy roads, less scraping your car — but milder weather has some major downsides. Everything from agriculture to wildlife to human health can be seriously impacted. Warmer winters also pose serious economic consequences in many states reliant on revenue from winter sports and recreation. The number

Cold Getting Less Extreme

For many locations in the U.S., middle-to-late January is climatologically the coldest time of the year. But extreme cold is on the decline as the world warms from increasing greenhouse gases from the burning of fossil fuels. This week’s analysis examines the coldest night each year in these cities. Even though we will continue to see cold
