It is better for the whales to go where the whales have the ability to dive longer and deeper to find cooler water.
Fossils can give information about past environmental conditions by showing the type of animal they belonged to. If a scientist found a whale fossil in a desert, he/she could assume that the desert was once an ocean as whales only live in oceans.

Hope this helps!
