Another way to explain the situation is to use an extreme example. Say, had the United States launched 100 nuclear missiles into the North Pacific Ocean right now, and detonated the weapons underwater. This would lead to an underwater flash boiling of massive amounts of ocean water, and lead to an area of hot humid air in that part of the world. The thing is, it doesn't affect just that area of the world, it also conflicts with usual weather patterns across the region. When the sun goes down on the region, it's still hot during the night, and it still steams the area. Whilst northern hemisphere regions surrounding bears the brunt of warmer humid weather, the hot air causes cold antarctic air to travel further north and affect areas (generally tropical) of the southern hemisphere that usually doesn't experience cold weather.
An example of this is when the French tested nuclear weapons in 1995 in the Pacific. Several days after the explosions, Australia and New Zealand had weather patterns inconsistent with usual patterns. I believe that the heavier rainfall along the east coast was earlier than predicted. I would surmise that it could have enhanced an early winter in the northern hemisphere.
I know the environmental science behind all this. But the global warming conspiracists seem to think that the earth is in a constant state of warming, when we seem to see a general balance of hot and cold weather systems. Personally, I think we have a joke of a cold snap to say that 2.6 degrees is cold. We have that weather here every year, and even down to freezing in Rockhampton.
