PORTLAND, Maine (NEWS CENTER) -- A Swiss family traveling the world to learn about climate change is making a stop in Portland.
The Schwoerer family is trying to visit seven summits by traveling the seven seas to experience every climate in the world. It is part of the "Top to Top" Global Expedition.
Their latest leg took them from southern California, north to Alaska, and across the top of the world and back down through the Arctic Circle to Maine.
"It was really a great journey and we became more optimistic each year about the future of our planet," said Dario Schwoerer.
His wife Sabine gave birth to all five of their children on the trip -- each on a different continent.
"They don't judge people by their color or if they are poor or rich," she said.
