Is somewhere else is getting hotter then it's going to be colder elsewhere, isn't it? Sun can only shine on one place at once.
Climate is different to weather in that the overall planet is getting hotter, but this particular week MN is cold, though overall it's like 0.25 degrees celsius warmer or something. It's not a lot but it -blam!-s up weather patterns like crazy and it -blam!-s with crops and the polar ice caps too...
