If you have ever had to deal with an air conditioner isn't cooling because of low freon, you'd know that the problem is because the coils get.. too.. cold. They get so cold that water in the air freezes around the coils to be the point there is little air flow possible. Why?
When the freon is low, the freon expands too much into the coils. More expansion, more temperature drop in the coils. Additionally, the compressor has too little freon to compress to sent out to the radiator. The local coil's temperature has gone down, but the overall temperature of the system has gone up. This is the difference between weather (local) and climate (overall average). The weather of the coil is cooler, the climate of the A/C system is hotter.
Global warming is creating changes in the energy flow, both atmospheric and oceanic. Consequently, you may have locally cooler temperatures because hotter temperatures in other create blocks energy movement that would otherwise heat your area.
Accounts without much posting history here get rate limited, as do accounts that we've penalized for posting too many low-quality comments or getting involved in flamewars. Unfortunately, your account is doing mostly the latter; in fact, flamebait on divisive topics is literally all it has posted so far.
That's not the intended use of the site, and we end up having to ban such accounts. (No, not because we disagree with your views—we basically don't care about that. We're just trying to have a specific kind of forum here.)
If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful. But please don't create accounts to break HN's rules with.

Which is it?
Was the mean global tempreture higher ("hotter" overall) or was it the same mean global tempreture with the usual climate cell to climate cell washovers making some a bit warmer and others a bit colder.
The assertion of AGW is that mean global tempreture has been essentially constant for some 200K years and has only recently 'suddenly' started to rapidly change (by environmental stability timescales) over the past century as a result of human activity pulling up billions of tonnes of formally buried carbon sequested in fossil fuels.
