With temperatures consistently breaking 50º F and 60º F and a peak high of 70º F on the 24th, February 2017 with a mean temperature of 41.6º F set a new record for the warmest February in history in the New York metro area. The previous mark of 40.9º F had been held by February 2012 in the year without a winter in the New York metro area. And with February 2017 being the latest in an accelerating trend of reoccurring anomalous warm winters and/or winter months there may be more truth than one can imagine in the dire warning above.

With its sustained spring-like warmth, people wore shorts and t-shirts, flowers blossomed, vegetables grew, and cold-blooded amphibians such as turtles and frogs emerged from their hibernation, an event that usually occurs in late March or early April for their first documented February appearance.

Although warm, anomalous winters often attributed to blocking patterns and the El Niño phenomenon have occurred in the past in the New York metro area, they are becoming more common with greater extremes in temperature readings – December 2006-January 2007, December 2011-February 2012 (the entire meteorological winter), December 2015 (with an astonishing 50.8º F mean temperature – an incredible 13.3º F above normal – a reading higher than some of the top 10 warmest Novembers!) and now February 2017.

New York metro area winters that used to consist of prolonged, sustained cold interrupted by a few warm days now consist of prolonged, sustained warmth interrupted by a few cold days. Consequently, global climate change appears increasingly responsible with extended growing seasons for crops and flowers alike. Roses often bloom into December, sunflowers have endured into January while some flowering bushes and trees are experiencing two blooms per year while exercising rapid recovery. In addition, the presence of cold-blooded fauna once unheard of during meteorological winter months are becoming more common with shorter hibernation cycles.

Although these winters are infrequent and abnormal, it should be noted the New York metro area has experienced a combination of warm anomalous winters and/or winter months a dozen times since the winter of 1739-40 with 25% having occurred in just the first two decades of the 21st century. These winters and/or winter months with summary diary descriptions, newspaper reports as well as my accounts from December 2006-January 2007 through February 2017 are listed below:

January-February 1740: A summer winter… generally fair and pleasant [with] only two snows, and sledding but about three weeks.[2]

January-February 1751: Pleasant weather… The weather like May (January 21st and 24th)… [T]his winter ends, wonder throughout the whole.[3]

January-February 1773: [W]onderful moderate… weather. There has been no snow, and but little rain since the 29th of December. We saw two robbins (sic). [4]

December 1777: Violets in blossom… a few days after Christmas.[5]

Winter 1824-25: Notably mild.[6]

Winter 1827-28: This winter… is remarkable for its mildness. [N]o snow or frost… [M]ild rains every where instead of snows… the first winter ever known that the (Susquehanna) [R]iver has continued clear of ice![7] The Hudson, with the exception of a few days, was navigated the whole winter… [T]he ground was bare almost the whole winter… The weather was mild with a few exceptions. Some days were warm. Bees came out. Flies appeared. The buds of willows swelled, and vegetation threatened to burst out…[8]

Winter 1931-32: Coatless citizens pluck[ed] pansies and pussy willows… sunbathers basked under the warm sun… [T]ulips, daffodils and hyacinths popped through the earth, roses broke out in a rash of buds and lilac and rhododendron bushes showed Spring-like activity… Magnolias opened… Robins flashed over pansy beds… [S]trawberry plants blossomed… [a White Plains, NY man] chased butterflies in his garden… [and] an audacious grasshopper leaped with joy.[9]

Winter 1949-50: Frogs peeped in [December]… Spring flowers (adonis, azaleas, forsythia, anemones and violets) bloomed… pansies threaten[ed] to run rampant… residents discarded winter overcoats… bluebirds were reported sighted… a groundhog even poked out his head in confusion… It looked and felt like spring![10]

December 2006-January 2007: Cherry blossoms and forsythia burst into bloom. Adonis and daffodils are enticed by spring-like temperatures. Turtles are reported observed in December; bees are present. No measurable snow is recorded until January 8th.


Winter 2011-12: Only one day of accumulating snow. All melted by the next day. Flowers abound in record diversity, and robins and bees are present in abundance every day. Turtles were reported seen in December; chipmunks were photographed in February. There was no winter! Autumn persisted followed by spring!



December 2015: A summer-like month. Summer and autumn flora coexist. A flowery paradise. No freezes. Frogs and turtles photographed through December 27th. Shorts and t-shirts are the apparel of choice. Christmas Day a good day for a swim in the Long Island Sound!






Nevertheless, despite their seemingly benign nature, the growing frequency of anomalously warm winters and/or winter months is reason for concern that should not be dampened by the fact the Earth has faced extreme epochal warmth before. Scientists are already warning of a possible impending mass-extinction event, the sixth in the planet’s history in which we may not be immune based on the projected loss of up to 60% of the world’s 504 primate species (our closest relatives)[11] and the falling human fertility rate “with half the world’s population already below the replacement ratio.”[12] It already happened with the Neanderthals Homo neaderthalensis (c. 198,000 BCE-22,500 BCE), a hominid species inhabiting the lands comprising Western Europe to Central Asia that was rendered extinct after their fertility rate plunged and therefore as global warming continues there should be a growing sense of urgency even if a correlation between the decline in primate and human fertility rates and climate change cannot be easily proven and our direct impact remains in dispute. Otherwise, while life may continue beyond the 21st century, it may no longer include Homo sapiens with crumbling buildings, overgrown decaying roads, a dark power grid and an abundance of non-biodegradable garbage and waste, the artifacts of the Anthropocene epoch (c. 1950-present) providing a sad testament of our past existence until everything is overgrown, crumbles and disappears into dust.
