Ice-free conditions continue in the Barents Sea region of the
#Arctic
Ocean. This is one area that has observed some of the largest losses of ice over the last few decades... compare the older years (dark/purple lines) to today! Map of this region:

Sea surface temperatures are warming across the entire periphery of the
#Arctic
Ocean in September. This is especially observed in areas with long-term declines in sea ice concentration, such around the Chukchi and Kara Seas. Data from NOAA OISSTv2.1. For more info

Our new paper compares GPR ice thickness data with models and looks at glacier thermal structures in Greenland, showing that thermal complexity (warm-cold ice) inside these glaciers is higher than expected. Read it here:

2024 glacier loss in Svalbard was beyond imagination! π± - Anomaly of up to 4 SD! - Amounts to ~61.7 Gt => 1% of the total ice volume - Comparable to that of the Greenland ice sheet (55 Gt), which is 50 x larger! ... Otherworldly! πͺ

Check out our latest work from the Dolomites. We tried to estimate the mass balance of the remaining Dolomites glaciers since the 1980s using LiDAR, SfM and historical imagery. No surprise: huge mass loss, shrinking area, and increasing debris cover. Paper:
