International Polar Day - Land and Life
Polar landscapes and polar terrestrial ecosystems extend from southern cold maritime islands to dry continental deserts in Antarctica, and from tree line across the continental tundra to remote northern islands in the Arctic. Ice, in the forms of permafrost, snow, and ice cover, plays a dominant role in all these environments, and the biological communities survive through remarkable adaptations and extensive migration. Polar ecosystems also survive in alpine areas. The climatological and ecological pressures that act on mountain-top populations also act on the northern-most and southern-most ecosystems.

Changing Earth: past and present
The polar regions are critical archives of polar change. By learning more about the Earth in the past, and how climates have changed previously, we are better able to predict and understand changes we are experiencing today, and will experience in the future.

Very Cool Science: a live global on-line event

From 1-14th July 2007, high-school students from across Australia and around the world gathered at The University of Sydney in New South Wales, Australia for the 34th International Science School (ISS), EcoScience – two weeks of scientific lectures, activities and social events with a focus on the environment and ecological science, and attention on IPY and the polar regions.

On Thursday July 5th, 2007 at 7.00pm Sydney time, the ISS presented a unique opportunity for high-school students to participate in a global webcast discussing polar science. Students, teachers and interested observers attended this 45 minute event hosted in Sydney, both at the ISS and online across the world, and participated real time in interactive presentations and discussions with scientists and residents located in the Arctic, Antarctic and their research facilities.
