If one doubted global warming, a photograph taken during today’s Columbus Day celebration in New York City would give evidence of it.
Mayor DeBlasio during celebration
As the photograph shows, Mayor DeBlasio is without a top coat and his jacket is not buttoned. On the 9th of October in New York!
I was out today in a cotton shirt with no jacket at all and was very comfortable. When I first moved to New York nearly forty years ago, it was chilly in September much less October. Today was nearer a summer day than what we knew as autumn several decades ago.
