The warming of high-latitude North America and the adjacent Arctic Ocean is the largest of any on the planet.

High-latitude cultures around the world marked the passing with festivals, feasts and tales of gods and ghosts rising from darkness.

During this eruption, the solar particles hitting the atmosphere produced auroras across the whole world, not just at high-latitude locations as is normally the case.

Glaciers in monsoonal climates, unlike high-latitude glaciers, gain mass from precipitation during the same warm season in which they lose mass from melting, which makes their behaviour complex.

For a number of reasons, computer models with added atmospheric carbon dioxide preferentially warm the mid-and high-latitude land areas of the northern hemisphere that are ice-free, which also enhances summer melting of the relatively shallow ice in the Arctic Ocean.

FORBES: Is Global Warming A Bipolar Disorder?

For example, significant cooling and strong dynamical effects after the Laki event and other high-latitude eruptions are believed to have caused decreased flow of the Nile River in Egypt and weakened African and Asian monsoons based on climate model simulations, with potentially very significant impacts on food and water supplies.

For instance, sea ice is predicted to increasingly shrink as a result of climate change: the late-summer Arctic sea ice may vanish almost entirely by the middle of the century, triggering unprecedented maritime challenges, with an increase in shipping and oil and gas exploration in high-latitude waters previously covered in ice.

In the case of the current mid-latitude chill, it is the high latitudes that are seeing the warming.
