climate change and chemical runoff. Climatologists believe that Australia is experiencing "accelerated climate change", which puts the vast Great Barrier Reef at severe risk. Rising ocean temperatures cause bleaching of the coral, when the plants expel the tiny animals living inside them and turning into colourless calcium skeletons. Caribbean A raise in temperature in the local seas of the Caribbean seem to be the cause of the bolstering hurricanes, which rip through the caribbean regions with increasing frequency and savagery! Siberia In one of the world's last wildernesses, global warming is causing profound changes to the lives of its people. Winters that used to reach -50 degrees are now a comparatively mild -30, which is causing the permafrost to melt. Arctic houses are subsiding, and the nomadic people of the tundra find that their annual migrations are disrupted by unseasonably warm temperatures or unexpected snow falls. You can see less and less snow and
frost each year. Tuvalu The low-lying Pacific islands of Tuvalu face the very real threat that they could be wiped out by climate change.
