According to NASA satellites it was the 15 coldest in 31 years for the globe with an anomaly of just0.043C.

NASA satellites are far more accurate than Hadley which lost 2/3rds of the world's stations in 1990, makes no adjustment for urban heat island and has very poor ocean coverage (earth is 70% ocean).

satellites are not measuring the surface. The lower tropo is a few months behind the surface warming.
