Exam 2 Answer

1 Why is the climate of the British Isles and northern Europe so mild, even though they are at the same latitude as frozen Labrador and Greenland? What happened in Panama in the Pliocene to cause this to occur, and how are Panama and the birth of the Arctic Ice Cap in the Pliocene linked?

It is because of the influence of the drift in North Atlantic 
The Gulf Stream runs from the tropical Atlantic across to England, bringing its warmth and moisture to northern Europe, so they get a lot of rain, but rarely have snow or hard freezes.
