Did you read that article?
It is talking about a shutdown of the thermohaline circulation system that could be a side-effect of, you guessed, human induced climate change. It works like this, we warm the Earth enough that the north Atlantic gets flushed with too much fresh water from Greenland's melting glacier. Fresh water is less dense than salt water meaning the start of the thermohaline conveyors is halted as the water in the north atlantic isn't able to sink. This then shuts down the currents that bring warm water from the tropics to the poles and submits the polar regions to a deep freezing trend. The whole this is caused by climate change. Your articles helps prove my point that we need action on this issue because we risk abrupt, catastrophic climate events.
Am I not explaining myself well enough? How can I be any more clear? The climate changes naturall. The rates of change that we have experienced are not natural. When we look at what is responsible for these rates of changes there is only one explanation, us burning fossil fuels.
