For the students in the schools I visited last week - here are some links about how the world is changing (click on the paragraphs below).

We are living through the greatest period of change the world has ever known.

The Polar Eskimos have always lived in harmony with nature, taking from the sea and land what they need to survive. But global warming has upset the equilibrium and left the future uncertain.

Scientists say Greenland is losing ice mass at an increasing rate - photos of the break-up of the Petermann Glacier.

For the first time in living memory, the sun rose above the horizon two days early – a phenomenon that has baffled Greenlanders and scientists. Some believe that the most plausible explanation is global warming. It is thought that the Greenland ice sheet and the glaciers surrounding the town are melting so rapidly that it is now possible to see a lower part of the horizon that was previously hidden by the ice.

Not only has global warming made hunting considerably more dangerous, it has also halved the hunting season.
