2016 was Second Warmest Year on Record for US

2016 was the second-warmest year ever recorded in the continental US.

The average annual temperature of the lower 48 states, according to NOAA’s National Centers of Environmental Information, was 54.9°F. That is a whopping 2.9°F above the 20th century average and only 0.4°F shy of the record that was set in 2012. This also marks the 20th consecutive year that the annual average temperature for the contiguous US was above its long-term norm.

From coast to coast, every state posted one of their top-seven warmest years. Georgia was record warm and Alaska, the nation’s northern most state, had its third consecutive warmest year on record. “The breadth of the 2016 warmth is unparalleled in the nation’s climate history,” NOAA said. “No other year had as many states breaking or close to breaking their warmest annual average temperature.”

2016 was also notable for its unusual number of weather and climate disasters that each totaled more than $1 billion in damages. In all, fifteen such events collectively caused $46 billion in direct costs and claimed the live of 138 people across the US. These incidents included drought, wildfire, four inland floods, eight severe storms, and a tropical cyclone. Only 2011, with sixteen events, produced more billion-dollar disasters.

The exceptional warmth of 2016 was driven by a combination of strong El Niño conditions at the beginning of the year and the long-term trend of human-caused climate change. These soaring temperatures, however, were not limited to US borders. Later this month, NOAA is expected to announce that 2016 was the planet’s warmest year on record for the third year in a row.

Weather records for the contiguous United States date back to 1895.
