Wonderworld: A Spectacular Photo Journey of Earth

She may look beautiful, but Earth is in danger. The planet just had its warmest winter on record, which comes on the heels of its warmest year. But data shows that the record-warm year of 2014 was no fluke. Global warming is affecting the entire planet, from the ice caps of the Arctic and Antarctic, to the depths of the sea and the plains of Africa.
