One half of Earth is cooling faster than the other, researchers have discovered.
The side of the planet which contains the Pacific Ocean is losing heat at a more rapid rate than the half which contains Africa, Europe and Asia.
Scientists believe the discrepancy is because the Pacific hemisphere has been covered with more ocean than the other half for the last 400 million years and land is a better insulator than water.
