September 2016 was the warmest September in 136 years of modern record-keeping according to a new analysis by NASA’s Goddard Institute for Space Studies (GISS).

For Michigan’s climate, it was another above average month, but in keeping with longer trends the most significant warming was seen around the more northern latitudes. The monthly analysis is built from publicly available data taken from circa 6,300 measurement stations around the world, ship- and buoy-based measuring instruments, and Antarctic research stations.

“Monthly rankings are sensitive to updates in the record, and our latest update to mid-winter readings from the South Pole has changed the ranking for June,” said GISS director Gavin Schmidt. “We continue to stress that while monthly rankings are newsworthy, they are not nearly as important as long-term trends.”

Michigan’s climate has already measurably changed. To learn more about what we know and where we understand that we’re heading, read about the changing Michigan climate projections.
