The biggest share is actually Russian environmental issue facing (40%), and we share the remainder with the U.S. (Alaska), Denmark the world today. The two (Greenland), Sweden, Finland, Norway and Iceland (where it passes through films this guide supports the small offshore island of Grímsey). As far as population is concerned, 80 show how the polar per cent of Arctic residents are Russian. regions – the Arctic and Antarctica – are the At the other end of the world, there is no similar division of territorial bellwether of climate possession. Antarctica is not owned by any nation, but rather is administered impacts throughout the by 48 countries through an agreement known as The Antarctica Treaty. The world. As these areas are document, originally signed by 12 nations on December 1, 1959, prohibits the warming faster than any ownership of any part of the continent by any country and restricts its use to other place on earth, temporary settlements strictly for scientific research. melting ice and collapsing glaciers pose a direct Both regions share a unique distinction: they are warming faster than any threat to humanity place else on earth. The Arctic is warming twice as fast while Antarctica is through rising sea levels warming five times as fast! This rapid warming is causing eons‐old ice to melt and subsequent flooding and pour fresh water into the world seas. Since 90 per cent of the world’s of coastal communities. fresh water can be found in polar ice, the melting of this ice represents a significant contribution to rising sea levels around the world. And while this impacts directly on us, there is also a major change taking place to the polar eco‐systems. Warming temperatures in the Antarctic seas are causing problems for marine life in their attempts to reproduce. Krill and starfish, in particular, cannot reproduce in these warmer waters resulting in a drastic and steady decline in their populations. Compounding this problem is the introduction of whale populations. They actually prefer the warmer waters and their massive consumption of krill is depleting the remaining krill populations at an alarming rate. Further up the food change, penguins and seals in Antarctica rely solely on krill as their food source and as the krill numbers fall so do the populations of penguins and seals. On top of the world, quite the opposite is taking place. The reduction of sea ice caused by warmer temperatures is exposing phytoplankton and Arctic marine flora to more sunlight. Photosynthesis is now taking place where it hadn’t previously resulting in an abundant bloom of new life. The additional life at the bottom of the food chain is not only providing more sustenance for the Arctic’s marine fauna, but is also attracting “exotic species” not usually found in Arctic waters. The two films featured in this resource guide provide startling evidence of these new climate change related discoveries at both ends of the earth from a unique perspective – the filmmakers travelled alongside teams of international polar scientists as they conducted studies and made discoveries directly in the field. 2 THE ANTARCTICA CHALLENGE: A GLOBAL WARNING and THE POLAR EXPLORER Quote Preview Questions "Of all the canaries in the climate coal mine, the polar What recent developments related to climate change are taking place in the regions and the mountain Arctic and Antarctica?
