Winter is the fastest warming season in the United States. In the northeast, it has warmed three times faster than summer. That said, cold snaps – periods of unusually chilly weather – are still happening, but less often.

According to a study by Climate Central, the frequency and duration of these frosty events in the contiguous US  have been declining as the overall climate warms. Looking at data from cities across the country, the non-profit news organization found that some places, such as Las Vegas, NV, have lost cold days faster than others. Here in New York City, the average reduction was 5 days since 1970.
