Adventures on Purple Polar Planet

The Environmental Space Explorer team of Josh, Deanna and Greg heads for a planet surrounded by a mysterious purple fog expecting to see lots of snow and cold weather. Instead, they encounter a planet whose surface is warming and inhabitants who are missing their snow and beautiful reindeer. The Earth kids realize they can help by sharing what they know about global warming on their home planet. Together they and their new friends come up with ideas and strategies to make things better and return the planet they dub Purple Polar Planet to its snowy self. Will it be enough, and can they convince the people to make the changes they must make in time to save their beautiful planet?
