B. Warm Caribbean Sea waters were forced up into the north Atlantic Ocean

Explanation:

South America and North America were not connected until 10 million years ago, but instead they were separated by water, thus the Caribbean Sea was connected with the Pacific Ocean. Because of this, the warm waters from the Caribbean were not forced further north in the Atlantic, but instead they were moving between the two continents. Once the two continents merged though, the warm Caribbean waters were forced to move toward the north Atlantic, thus they started to move towards Europe. Because they were warm currents, they significantly warmed Europe, up to 10 C degrees more on average, significantly changing the climate in this part of the world.
