Today in CWI, we watched another movie..this one is on global warming. Bruns finished the Canada tests too.In the movie, it said that Greenland is 80% covered in ice and has warmed by 8 degrees in the past couple years, supposedly because of the greehouse gases were releasing. Because of global warming, some of the ice has melted which revealed a new island.They went and caught the polar bears to do tests, what they found is that they're changing. Because of global warming, their food supply isn't as great, in result, they're getting smaller. They have even resulted to canabalism. Another result of global warming is polar bears drowing because the ice has melted making a lot further for them to swim.In the south pacific, global warming is affecting them as the shore line is receeding and now, some of the places they owned like their garden are completely under water now. Now they have to survive on the food that comes from a diferent island. That doesn't sound like such a big deal, but it only comes twice a year):They also think that coral bleaching is also an effect from global warming. It destroys the coral reef, which is a really bad thing.
