The lede: “Earth’s global surface temperatures in 2018 were the fourth warmest since 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).”

The meat, interestingly enough in a chart caption: “This line plot shows yearly temperature anomalies from 1880 to 2018, with respect to the 1951-1980 mean…Though there are minor variations from year to year, all five temperature records show peaks and valleys in sync with each other. All show rapid warming in the past few decades, and all show the past decade has been the warmest.”

Bottom line: our climate in changing. You can debate the why, and bring politics into it if you must, but temperature data is data. It is the truth. Our planet is warming at a significant pace, unparalleled in our recorded history.
