According to NASA, 2016 was the warmest year on record (with the records stretching back to the late 1800), and the third year in a row to set a new record for global temperatures. The average global temperature was calculated to be about .99 degrees Celsius above the mid-20th century mean, with the average global temperature being 1.1 degrees Celsius higher than it was during the late 19th century (coincidently, the industrial revolution happened during the middle of the 19th century).
This is a calculated global average based on data recorded across the planet; in a lot of places, weather dynamics meant that local temperatures did not get record-breaking high. The majority of the United States was not one of those places. Thanks to an El Niño weather pattern in the Pacific (meaning that the ocean was abnormally warm out there), Nearly all states experienced higher than average weather that was well above their 20th century means (Georgia was the only one to set a new record, though).
At the time of this post, I’m living in a relatively elevated area around western NY, and the last few weeks started out somewhat ridiculously mild (if I had wanted to, I could have gone outdoor sunbathing out on the mountain side during a weekend in early January), but are now properly cold and snowy. The dissipation of the El Niño means that this year should be cooler for North America than the last one; after the blizzard I trudged through to get back to my dorm, I am not too surprised.
