today we went over the US map for the test next tuesday and we got our topics for the iraq assigned blog and got the topics for the planet in peril video which are:
1. Greenland is Melting/Discovering Islands
greenland is melting because the temp is rising because of global warming, carbon dioxide is the main cause and it is believed that we are causing it, the green house effect traps heat and attracts green house gases. greenland is 8 degrees warmer than it was 10 years ago. the positive feedback loop is when ice melts the water absorbs more heat and melts more ice. moulin is when ice melts and the water cuts into the ice and goes underneath the ice and picks it up and breaks it apart
2. Polar Bears at Risk
polar bears are now on the endangered list and the first to be put on there because global warming, 2/3 of the polar bears could be gone in 50 years. they are smaller now because they have less to eat, some polar bears are drowning because the widening of the ice sheets are getting larger and they resort to canibalism which isnt normal, 2007 ice has melted that was about 6x the size of california.
3. The Carterets are Sinking
the carterets are sinking because of the rising waters, it was built on a volcano or the reefs are dying. the reefs are bleeched are because of bacteria. the reefs are there to protect an island from storm surges, the reefs that are dead attract less fish and with less fish the people have less food, they stay on the island because they enjoy their lives there and other islands have to much crime and violence. thermal expansion is when the water warms up the sea expands
