A recent 'coldwave' (late June to 14 July) with snow pushed Greenland ice sheet daily mass balance slightly more positive than normal for the hydrological year to date... Yet, as you can see, the ice sheet still on track for net mass loss.

entering the usual peak weeks of the melt season, Greenland 'whiteness' aka 'albedo' is roller coastering and currently on the dark side after a snowy period end of June to ~12 July #Sentinel3 Copernicus EU

The Earth has warmed before but never this fast. This graph compares current & projected warming to past extinction-level events. In the past: 🌡️ +5°C took 5,000+ years Now: 🌡️ +5°C could happen in just 200 years This is NOT natural.

The Greenland ice sheet is currently on pace for a 'usual' ice loss of ca. 170 Gigatonnes, rising global average sea level by ca. 0.5 mm this year. There have been two mid summer snowfall episodes that is keeping the ice sheet from losing even more. PROMICE

This is absolutely astonishing & historic. Finland has recorded 20 consecutive days of temperatures >30°C. The previous record was 13 days in 1972.

We're now late enough in the Greenland melt season to know it's not going to be a record ice loss year. Nevertheless, >100 Gigatonnes ice loss equates to more than all the ice in the European Alps being lost this year!
