NASA GISS surface temp data [0]. Feb 2016 to Feb 2018. It's a noteworthy occurrence (and not something the news cycle would pick up) since the focus is always on warming. It certainly doesn't refute the short-term trends present.

Cherry picking 2 data points is not the right way to interpret a trend. 2016 was a spike, but if you look at the trend over the past 20 years (in the data set you linked) it is clear temperature is trending upwards at an accelerating pace.

You're burying the lede here.

While 2017 was slightly cooler than the year preceding, it was the second hottest year since global temperature records began in 1880.

From the same page you linked. https://www.giss.nasa.gov/research/news/20180118/

We'll see how 2018 compares. Look at the chart and you can see that it's not a straight line, it has ups and downs. I see no reason at all to assume that it's trending downward for the next few decades to erase the increase seen over the last century.
