record high temperatures

Signals Summary: Climate change is leading to more record high temperatures in every season, and global warming has contributed to the severity and probability of 82 percent of record-hot days globally.

Article Excerpt: It may be the coldest time of the year, but this weekend felt more like spring across the Northeast, where Boston reached 70 degrees on back-to-back days Saturday and Sunday.


What's more, Boston reached 74 degrees Sunday afternoon, setting a new all-time record high for January. The previous record for the month was 72 degrees, set on Jan. 26, 1950.

This record warmth is about 35 degrees above average mid-January highs, the coldest averages of the year, and more typical of late May, according to the National Weather Service in Boston. The average high this time of year is only 36 degrees.


More than 60 other cities in the eastern United States tied or set record highs for Jan. 11 on Saturday, the National Weather Service Eastern Region noted in a tweet.


New York City hit 68 degrees at Central Park, breaking the previous daily record of 66 degrees for Jan. 12, set just three years ago in 2017. That followed the record high of 69 degrees that was set on Saturday.
