Did you ever wonder the specific cause for the new ocean weather patterns?
Between 1985 and 2007 I have personally witnessed the melting of glacier ice and the recession of the glaciers in Alaska.
Adding salt to water when you cook changes the boiling point (and freezing temperature) of the water. Taking salt from water also changes the temperature parameters of water.
As the polar ice caps melt the oceans are cooling, but also salt water is being diluted, which changes the way water behaves. The result is that ocean currents that have existed for centuries are changing course and bringing a permanent change to weather patterns.
We did it – we will have to get use to it.
