Document Summary

Ice on greenland melted causing sea level to rise (1mm per year) Sea level rise doubling every 10 years. Greenland s rate of melting increase over the last 4 years suggests the melt rates would double every 10 years. Melt map = places where snow has melted but can refreeze. Extreme melt events in greenland have been detected in ice cores and they occur on the order of every 1000 years. The main contributors of increasing melt water from greenland to the ocean occurs when outlet glacier melting and flow rates increase. Warm water is being pushed towards greenland and is causing the ice to melt. Strong winds are changing direction due to global warming. Recent increasing melt rates on antartica ice sheet have been attributed to winds that are ringing warm water to the antarctic coast. The recent assessment of antarctica icecap melting was based on computer models.
