But others think the situation could be an evolutionary development to avoid detection.

The Earth's average annual temperature has been rising for decades, but not in the last 15 years — colder winters and hotter summers notwithstanding. Now scientists offer evidence that this "pause" in average warming is because a cooler Pacific is temporarily taking up more heat than usual.
