A mosquito, my albedo
I'm not gonna lie, I just wanted to say that. But also, 172 quintillion joules.
Year 2011 albedo (multiply by 100 to get % units) over the Greenland ice sheet is the lowest observed in the 12 years since MODIS observations began day 65 year 2000. 11-day running median Greenland ice sheet albedo from Moderate Resolution Imaging Spectroradiometer (MODIS) MOD10A1 data. The dashed line represents the 2000-2011 daily average.
Darkening of the ice sheet in the 12 summers between 2000 and 2011 permitted the ice sheet to absorb an extra 172 quintillion joules of energy, nearly 2 times the annual energy consumption of the United States (about 94 quintillion joules in 2009).
This decline is not only over the lowest elevations, but occurs high on the ice sheet where melting is limited.
