Back when I studed Geography and environment and climate, we learned the effects of ocean currents on climate, and on patterns of temperature range in various locations along the coasts of various continents. It is the oceans currents and the movement of warmer and cooler water that creates in part the climate ranges of locations on our planet. It is why the Pacific Northwest is not as frigid as one might expect for its latitude, and why Great Britain also is not a deep freeze. It also affects patterns of precipitation. I think there are maps you can look at and read about all of this on line. Possibly at the NOAA web site. If temperatures and currents then changed, it would have a dramatic impact on world climate zones.
Yeah I have noticed for so-called climatologists they are ominously silent in regards to the other well known and factual particulars of climate... They ignore the North Atlantic Oscillation, The arctic oscillation, and the Antarctic oscillation. And the only mention of the North Atlantic current was in their PR movie "day after tomorrow".. And they even fudged that up terribly..
Just more evidence of this being a political agenda rather than a scientific one...
What climatological journals do you read?
Why bother reading propoganda....
