Approximately 85 billion metric tons of CO 2 are released each year. The past 100 years the temperature has increased 0.5 degrees Celsius. Precipitation has increased recently. Land usually flooded every 100 to 500 years. Hurts cattle and humans with more frequent heat waves.
Dry seasons have less water, hurts crops.
The Northern Polar Ice Cap is expected to melt, but the water levels are not expected to rise significantly with this because water has already been displaced by ice. The Southern Polar Ice Cap is not displacing water. It is located on land shelves. When this melts, the water levels are expected to rise 5-6 meters, mixing fresh water into salt water. This will upset the global conveyor patterns of ocean currents.
