Well now I am in the making of a timeline. This timeline here is unique as around the area and length of the Atlantic Underwater Mountain Range, there is a long contienent.

What I want to know, is what would be the environmental affects of having a continent smack dab in the Atlantic streching from the Middle North Atlantic down to lower South America.

I know this would affect the ocean currents, and would cool down Europe, but to what extent?
