4: Scientists around the world released a report in February 2007 warning that by the beginning of the next century, sea levels could rise by how many inches?
1-3 inches
Sorry, the correct answer is 7-24 inches. But this is a conservative estimate, based almost entirely on the expected expansion of ocean waters due to rising temperatures. Far greater sea level rises are expected if the water bound up in polar ice sheets melts, as it has started to do. The recent report from the Intergovernmental Panel on Climate Change suggested that if greenhouse gases continue to accumulate at even a moderate pace, temperatures by 2100 could be what they were 125,000 years ago when sea levels were 12 to 20 FEET higher than today.
3-5 inches

You are correct. But 7-24 inches is a conservative estimate, based almost entirely on the expected expansion of ocean waters due to rising temperatures. Far greater sea level rises are expected if the water bound up in polar ice sheets melts, as it has started to do. The recent report from the International Panel on Climate Change suggested that if greenhouse gases continue to accumulate at even a moderate pace, temperatures by 2100 could be what they were 125,000 years ago when sea levels were 12 to 20 FEET higher than today.
