Global average surface temperature in 2016 was 1.69°F (0.94°C) above the 20th century average. This is the third year in a row that our planet has set a new record for unusual heat.

2014 was, quite likely, the warmest in the past 135 years. We know that because we know the uncertainty.
When it’s freezing outside, it can be icy too. People walking down the street find their feet sliding in directions that they didn’t intend. A few unlucky ones slip and fall. But have you ever wondered why we slip?
At Boulder's climate station, 14.6 inches of rain fell between September 9, and early morning, September 13, 2013. Most of that rain (more than 9 inches) fell on September 12. That’s a lot, right? Or is it?
In the scientific sense, climate normal is the average of the past 30 years of data about temperature, precipitation and other aspects of weather. Climate is what’s normal, what’s typical, what you’d expect. Yet, we now have a new normal for climate. If you average the past 30 years of temperature data you will have a higher number of degrees than if you average an earlier 30 years of data. Climate is changing, which means normal is changing, at least in the scientific sense. We have a new baseline.
Records set during the Olympics by fast swimmers and runners and all sorts of other athletes were exciting. They made people jump out of seats in living rooms around the world and cheer. But records set by our planet are another story. Those make me uneasy.
