The study compares the rate of warming from 1970-2012 and compares it to the rate of warming from 2013 to the present. It's conclusion is that the warming rate has not increased in recent years.
Just because there isn't an increase in the rate of warming doesn't mean that global temperatures aren't warming. There just isn't enough data to say it's a surge.
Per study:
"In short, a 40% increase in the 2013–2040 warming rate relative to the 1970–2012 rate will be needed to declare a significant warming surge by 2040."
So, basically, the warming trend is steady.
If you have a tumor and it's steadily growing at 10% per year..... Yay?
You still have a problem.
