Here's a link to a documentary on Greenland featuring myself, Asa Rennermalm and Scott Luthcke (on the science side). 
The documentary was aired on the Special Edition of Christmas Eve on CCTV - America's Now  show  (here's the link to the original CCTV site http://cctv.cntv.cn/lm/americasnow/01/index.shtml). 
Most of the scenes of water rushing into the ice and other similar footage were collected by our team in the field in 2011. 
Enjoy !


 
 
Here's a movie showing the melt extent over Greenland for 2012,  2010 (the previous record) and the 1981 - 2010 mean that Mauri Pelto put together using data provided by me.You can find the same figure on our most recent paper on the records in 2012 (see post below).

 Thanks to Mauri and enjoy !
 
 
Here's the link to the updated results for the whole 2012 melting season in Greenland, including total mass loss from GRACE. 

Overall, in 2012 ALL of the considered parameters (albedo, bare ice, surface mass balance, melting, total mass change, etc.) set a new record !

The paper has been published on The Cryosphere Discussion. Here's the abstract of the paper, together with the title and the co-authors. The Surface mass balance form the model and the total mass change from GRACE

I am re-posting an interesting message from Mauri Pelto on the Zachariae Isstrom ice loss. The original message is below ....


ORIGINAL MESSAGE
Dear Glacier Colleagues:
Petermann has got lots of attention this summer but the losses in area of Zachariae Isstrom and the open water currently at its front are worth noting.  Below is a link to a post on the glacier with numerous Landsat images, this is meant only as a  visual update not a substitute for the detailed research that has been conducted and will continue on this important outlet glacier.

Melting in Greenland set a new record before the end of the melting season. Over the past days, the cumulative melting index over the entire Greenland ice sheet (defined as the number of days when melting occurs times the area subject to melting) on August 8th exceeded the record value recently set in 2010 for the whole melting season (which usually ends around the beginning or mid September).
Picture
Standardized melting index (SMI) for the period 1979 - 2012. the years between 1979 and 2011 use the full length season (May through September) where 2012 uses only the available period May through August 8th. Note that 2012 value is much higher than any of the previous years, despite the shorter period.

A link to the ground data collected along the K-transect by the Institute for Marine and Atmospheric Research Utrecht, Utrecht University, the Netherlands can now be accessed through a new link under the Data section. An example of the available plots is reported on the left. The institute has been operating several automatic weather stations on the western Greenland ice margin (K-transect) for many years and the data of the current calendar year can be viewed from the link under Data or here. Thanks to Carleen Tijm-Reijmer (IMAU) for sending the link.

Here's a link to Jason Box 2012 analysis of albedo over the Greenland ice sheet. The reduction of the albedo is a critical factor for enhancing melting over the Greenland ice sheet. The image on the left shows the ice sheet albedo time series updated through July 2012 by Jason Box. 

To better understand the importance of this mechanism you can check a recently published paper on the Cryosphere Discussion by Box et al. (2012) in which we focus on this problem or another paper (Tedesco et al., 2011) that we published on Environmental Research Letters focusing on the role of albedo and accumulation on the 2010 melting recording in Greenland. Both papers are also available in the Scientific Literature section of this site. 

 
 
NOAA today posted the following focusing on melting at Summit during the month of July 2012. 
Here's the full link:

The plot below shows the passive microwave brightness temperature time series over Summit recorded between 1979 and 2011 (the ensemble of gray lines) and the time series recorded during 2012 (black thick line). The ensemble clearly shows that things are relatively stable at Summit, with relatively small interannual variability.
