Sólheimajökull is a glacier in southern Iceland, nestled between the Katla and Eyjafjallajökull volcanoes. It's part of the Mýrdalsjökull glacier and is a popular spot for tourists due to its size and easy access. However, it's melting pretty fast, about 60 meters per year, thanks to warmer temperatures from climate change. So, if you want to see this icy wonder, better hurry before it disappears!
