Greenland Ice Melt –
Relevant and Irrelevant Factors

Greenland Ice Melt |
||
|
|
Relevant |
|
|
|
1 |
Historical ice sheet surface temperature (all of Greenland) (see below) |
|
|
2 |
Historical ice sheet mass |
|
|
3 |
Data showing correlation between sea temperatures and ice melt |
|
|
4 |
Data of historical contribution of Greenland ice melt to sea level rise |
|
|
5 |
Ice mass loss from 1990(?) – 2007 due to warmer sea water temperatures (see below) |
|
|

|
Not Relevant |
|
|
|
|
Historical temperature for single location (unless explicitly state that it is typical or atypical of Greenland) |
|
|
|
Ice flow of a single glacier location (unless explicitly state that it is typical or atypical of Greenland) |
|
|
|
Data showing no correlation between air temperatures and ice melt (at least until 2007, warmer sea water, not air temperature, was the cause of ice melt) |

Needs further study |

|
|
|
How much of Greenland’s ice is likely to be affected by warmer sea water? |
|
|
|
What is the range of temperatures forecast for Greenland in a “business as usual” scenario? |
|
|
|
What is the likely impact on the ice mass given the likely temperatures forecast for Greenland in a “business as usual” scenario? |

Greenland glaciers – melt due to sea
current change, not air temperature
