Frontiers explores new ideas in science, meeting the researchers who see the world through fresh eyes and challenge existing theories - as well as hearing from their critics. Many such developments create new ethical and moral questions and Frontiers is not afraid to consider these.

| Gabrielle Walker in Antarctica |
Antarctica
Antarctica can be hostile, remote and inaccessible, but it holds some of the clues to the future of our changing planet.
In Frontiers this week Gabrielle Walker reports from this vast, frozen continent.
She joins scientists on a mountain top on the Antarctic Peninsula, drilling an ice core to recover the climate record over the last thirty thousand years.
In all the models of climate change, this is the brightest ‘hot spot’ for global warming. Already, vast ice shelves are breaking away from the continent nearby.
Further south and more worrying, the biggest glacier in Antarctica is accelerating at an alarming rate. But is this the result of natural cycles or a consequence of global warming that could lead to a catastrophic rise in world sea level? |
