The Polar regions play a crucial role in balancing global climate – with the poles heating up much faster than the rest of the world. Yet, climate projections for the Polar regions still have significant uncertainties. This is hampering efforts to curb climate change and deal with the effects we already see at play not only within the Polar regions, but also in Europe and the rest of the world. PolarRES, a new research project funded by the European Union’s Horizon 2020 Programme will work to make climate projections in the polar regions more reliable.
