When environmental variability is within the range of these adaptive measures, the social-ecological system can thrive. Thus, there are fundamental components in place in polar regions already to help ecosystems and people adapt to some degree of climate change. However, as climate change impacts like warming waters, sea ice loss, permafrost thaw and erosion systematically alter components of the system, shift species increasingly poleward, and disrupt linkages between species and people, the ability to adapt is reduced. There are critical tipping points  where changes may cascade, self-reinforce and accelerate, outpacing adaptation actions and force natural and human systems irreversibly  into novel regimes. The risk of crossing tipping points is greater and the probability much increased after mid-century under scenarios without global carbon mitigation , where changes are largest and most rapid.
