Climate Change: Evidence
Global sea level rose about 17 centimeters (6.7 inches) in the last century.Snow and Ice - Weather in Antarctica - Antarctic Connection
...
All three major global surface temperature reconstructions show that Earth has warmed since 1880. 5 Most of this warming has occurred since the 1970s, with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years.
...Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005.
The Antarctic Ice Sheet is a thick, ancient sheet of ice with a maximum depth of nearly 3 miles (15,000 feet). It is the iceberg 'factory' of the Southern Ocean. This icesheet contains over 5 million cubic miles (30 million cubic km) of ice. The weight of the Antarctic ice is so great that in many areas it actually pushes the land below sea-level. Without its ice cover Antarctica would eventually rise up another 1500 feet (450 m) above sea-level.Antarctica Climate Number: 7.2 million cubic miles | Earth Gauge
Ninety (90) percent of Earth’s ice sits on top of Antarctica, a 5.4 million square mile continent. Virtually all of this area is covered by an ice sheet that can be three miles high with an average thickness of 1.24 miles, giving it an approximate total volume of 7.2 million cubic miles.Note that we don't know how many cubic miles of ice are in Antarctica, but we allegedly do know that the number dropped by 36 in three years, and that CO2 was the cause.

Wow at this rate it will be ice free in 30,000 years. Real serious.
