I couldn't find a post covering this so I felt I might just add one myself. This meme has been doing the rounds on Facebook and Reddit for a few years now and while a significant amount of ice has melted because of the way we've been treating the Earth, Greenland is still very much covered in ice which this satellite picture on Google Maps proves.
As for the image used in the meme itself, it actually comes from a CGI animation that someone made depicting a predicted outcome for Greenland if we don't do something to improve our climate https://www.cg4tv.com/3d-animation/greenland-cap-melting.html
There's also the massive elephant in the room which is the fact that the screenshotted post used to make the meme is from 24/7 HipHop News who aren't exactly what I'd call a reputable source when it gets to information on climate change (sorry if that sounded snarky but it's kind of hard not to).
To me this meme is what I'd call bunk with good intent, it wants people to believe that the situation in Greenland is even worse than it is to try and scare people into doing the right thing, but the problem with going too far with such tactics is that it can just make people feel hopeless and even cause them to make less of an effort.
