It keeps getting colder
Global warming refers to the increase in global average temperatures. There is no assurance that temperatures everywhere will increase at the same rate, in fact the opposite is assured. Some parts of the world will change in temperature very little, others will change a lot. Some may even get colder.
But the average is going to go up in the long term. Currently 0.18°C/decade.
