Polar research ship returns to Europe after 'fantastic' 1½-year journey

The ship was stuck in the high artic because it got stuck in the ice they had to wait tell I t melted before they can go home… while they where there they studied the ice and they could see that the climate was changing because of the different types of ice I don’t know how they do it but that’s what they said they where doing. I think that they should go back and study that ice more to tell people more people that global warming was real. It took them a 1 ½ to get back home because they froze in while they where studying the ice… its really cool that they can tell what’s happing to the climate bye looking at ice.
