that list as the hottest year, surpassing the previous record in 2009, and we shall know about 2011 soon enough). Natural animal and plant
populations are being devastated all over the globe as their environments change.6 Many animals respond by
moving their ranges to formerly cold climates, so now places that once did not have to worry about disease-bearing
mosquitoes are infested as the climate warms and allows them to breed further north. 4. Sea Level Rise. All that
melted ice eventually ends up in the ocean, causing sea levels to rise, as it has many times in the geologic past. At
present, the sea level is rising about 3-4 mm per year, more than ten times the rate of 0.10.2 mm/year that has occurred over the past 3000 years.
Geological data show Üiat ttie sea level was virtually unchanged over the past 10,000 years since the present interglacial began. A few mm here
or there doesn't impress people, until you consider that the rate is accelerating and that most scientists predict sea levels will rise 80-130 cm in
just the next century. A sea level rise of 1.3 m (almost 4 f...
