I 2019 gikk det bilder av hunder som løp på smeltevann, viralt på internett. Media hadde funnet «bevis» på at klimaet hadde skiftet på Grønland. Steffen Olsen i det danske meteorologiske institutt havnet plutselig i trøbbel da isen hadde fått mye overvann.

Photo of sled dogs walking through water shows reality of Greenland’s melting ice sheet
Senere kom også «videobeviset»:
Visitgreenland hadde en artikkel som beskriver dette fenomenet som noe normalt for lokalbefolkningen. De skriver:
The picture has been interpreted by many as dramatic confirmation of climate change, and this is understandable, as it looks pretty dangerous to a non-local eye to see dogs wading out into melting sea ice. However, this situation is not as unusual in Greenland as the hype would lead us to believe. It is, in fact, common for pools of meltwater to collect on sea ice in the early summer, and dogs and their mushers are used to traversing the ice in these conditions. Local mushers are practiced in telling when the ice is still thick enough to be crossed without risk. In this area, the ice is particularly thick, so it is common to experience a lot of standing meltwater as there are very few cracks in the ice for the water to drain through.
Dette skjer altså fordi isen i området er veldig tykk og at det er få sprekker i isen som smeltevannet kan dreneres ut fra. Det skjer ofte i Norge også. Hvis det er åpent inne mot land så kan tunge snømengder få isen til å synke. Snøen smelter og man får samme effekt som på bildet.
Visit Greenland skriver videre:
The team who took this photo were indeed surprised to see so much standing water on the sea ice this early in the season – this would normally be the scene in late June or early July – and the early accumulation of standing water can be attributed to a recent period of unusually warm weather which has rapidly melted the sea ice. But scientists insist that it is not that straightforward to link such short events to climate change. Although these conditions constitute an extreme weather event, this is not the same as a change in the climate. Climate change is observed in Greenland, but it can only be legitimately defined as changes that persist for an extended period, typically decades or longer, as defined by the Intergovernmental Panel on Climate Change (IPCC).

Artikkelen om klimaendringer i Grønland sier dette:
The Arctic is warming twice as fast as the global average, and is experiencing some of the most intense effects of climate change, with southwest Greenland seeing the most rapid warming (about 3°C during the past 7 years). In July 2013, the temperature at Maniitsoq airport, just beneath the Arctic Circle in west Greenland, was recorded at 25.9°C. This is the highest temperature ever recorded in Greenland.
Det kan være at de ikke har hatt gradestokker der ute før i senere tid, men vi vet at det har vært mye varmere på Grønland. Det finnes mange artikler på internett som skriver som dette, Historienet.no:
Når Visit Greenland sier at Arktis varmes dobbelt så fort som det globale gjennomsnittet så er ikke det så veldig, veldig unikt for Grønland og Arktis: Everywhere Is Warming Faster Than All Locations
