The analytics are in! The year 2017 is the second or third hottest year on record, continuing the ongoing trend of warming. Both the two years prior were also record-breakers, but what really sets 2017 apart is the absence of El Niño influence. We expect warmer years when El Niño stirs, because this non-anthropogenic change in ocean currents warms temperatures worldwide. We don't expect them in the absence of an El Niño. There's been little doubt that humans play a significant role in global climate, but that humans now eclipse the effects of non-anthropogenic cycles is definitely something to think about! I found these factoids put out by NOAA to really put things into perspective:

My town was 1.2º above average. What was yours?
I got to thinking about this topic again today given the present weather. Yes, I know, I know... weather is not climate. But when we've been getting consistent rain events in January, that feels just wrong to my very bones. Are the 6+ inch snowfalls of my youth truly a thing of the past? I hope not. Might need to move to Canada to get my snow fix.
- No one born since 1977 has experienced a cooler-than-average year compared to the 20th century average. Or, to put it another way, it's been 41 years since we've had a cooler-than-average year.
- The six warmest years have each occurred since 2010.
- From 1880 to 1980, the world set a new temperature record about every 13 years on average. Now that happens once every 3 years.
- The annual global average temperature increased at an average rate of 0.07 degrees Celsius, or 0.13 degrees Fahrenheit, per decade since 1880. However, this rate has sped up to more than twice as fast since 1980.
