CSIC SCIENTIFIC CHALLENGES: TOWARDS 2030, Vol. 7: GLOBAL CHANGE IMPACTS, CHALLENGE 4 The Polar Regions are key Earth’s climate regulators and, hence, any perturbation in their baseline conditions can have global repercussions. Owing their intrinsic particularities such as the presence of huge amounts of sea and continental ice, their terrestrial and marine ecosystems are highly sensitive to temperature fluctuations. In fact, both the Arctic and the Antarctic Peninsula are the regions where temperature has raised most and faster than any other Earth’s place. Moreover, other environmental issues related to anthropogenic changes such as the occurrence of contaminants, invasive species, emerging diseases and exploitation of living marine resources are also affecting the Polar Regions. Therefore, sound, detailed and long-term knowledge of the polar systems functioning, interactions and feedbacks is of paramount importance to establish and characterize the main impacts and consequences in both polar and extra-polar latitudes. Only then, efficient and environmentally friendly measures would be established both to mitigate the negative effects of current anthropogenic impacts Peer reviewed
