The melting of ice in the Arctic is happening faster, and scientists haven't found any natural processes that could slow it down. If the Arctic and Antarctic glaciers keep melting at this rate, it could cause sea levels to rise around the world, flooding the coastal areas where a lot of people live. Research from the National Center for Atmospheric Research (NCAR) and the University of Arizona shows that if greenhouse gases keep increasing, temperatures in the Arctic could rise by 3-5°C by the end of the century. This means Arctic summers by 2100 could be as warm as they were about 130,000 years ago, when sea levels were as much as 6 meters higher than they are today.

Lake sediment records from southern Greenland provide valuable information about environmental and climate changes over the past 10,000 years. These records highlight how soil dynamics have influenced vegetation shifts and underscore the increasing human impact on soil erosion in recent decades. Additionally, both past and present changes in the movement of heat through the atmosphere and oceans appear to play a major role in shaping the regional climate and the behavior of the ice sheet. Climate models are used to predict future temperature changes in Greenland, which may occur at a faster rate than similar events in the past during interglacial periods. Within the next century, as greenhouse gas emissions continue to rise, Greenland's temperatures could reach levels last seen during the last interglacial period, about 125,000 years ago.
