By the time today's teenagers turn 50, New England's climate will feel very different.

Under current warming trends, states like New Hampshire will have shorter winters with less snow. Some coastal areas will be underwater. And it will all be worse without swift action to stop fossil fuel emissions.

This possible future is calling more and more of New Hampshire's young people to act -- and they're getting results.

Ember and Azalea Morgan of Andover remember where they were when they first realized what climate change was doing -- and would do -- to their planet.

"We were at a friend's house for a party, dinner, thing, blah blah blah," says Azalea, age 9. "And we were watching TV, National Geographic, I think, and I saw this video about, like, polar bears and global warming and how the ice is melting and they don't have a lot of ice left. And I got really sad."

Scientists and the United Nations say the world has about until 2030 to prevent the worst effects of climate change.  That's about when Azalea and her sister Ember, 10, will be in college.
