AIUI, the assumption is that most of the first - year ice will melt, and much of it is located around the North Pole this year, so it will melt late (if at all) because of less insolation at high latitudes.

But recent research suggests that while climate change will open more land in higher latitudes for potential crop growth, the gains will not be great, because the conditions for multiple harvests in the tropics will be reduced.

Charged particles from space easily move along geomagnetic field lines and intercept the upper atmosphere at high latitudes (that is, toward the poles) because that is where the field lines originate.

The Atlantic Ocean circulation that carries warmth into the Northern Hemisphere's high latitudes is slowing down because of climate change - and is at its weakest point in the past 1,600 years.

I suspect it's not 1C over all the globe but just over relatively dry parts of the globe (higher latitudes over continents) where conduction (and hence surface temperature) has to increase make up for the higher impedence through the radiative path because there's no latent path (and hence no rise in temperature) to make up the difference.

AGW is on the order of 0.05 C / decade globally and it's a good thing because it is largely delivered to high northern latitudes in the winter which benefit from milder winter temperatures.

Land temp rises more because it tends to be dry, especially in winter in higher latitudes, and thus lapse rate feedback (which is negative) doesn't play as large a role in reducing CO2 sensitivity.

This can have a global impact on climate, because the convection in the ascending branch of the Walker circulation triggers planetary scale waves that radiate to higher latitudes.

In 1938, Callendar himself concluded that, «the combustion of fossil fuel -LSB-...] is likely to prove beneficial to mankind in several ways», notably allowing cultivation at higher northern latitudes, and because, «the return of the deadly glaciers should be delayed indefinitely».

This is because local temperature anomalies at high latitudes are well correlated over ~ 1000 kms, so in fact 55 point samples they took covers a huge area.

For example, as long as the rise in global average temperature stays below 3 degrees Celsius, some models predict that global food production could increase because of the longer growing season at mid - to high - latitudes, provided adequate water resources are available.

The disruption part is because they realized that greenhouse warming wasn't evenly distributed across the globe but rather is apportioned by latitude with higher latitudes getting a lot and lower latitudes getting little with the Arctic glowing like a hot coal in temperature anomaly maps.

The first difference arises because annual average temperature change is greater than summer temperature change at high latitudes, but the mass balance sensitivity is greater to summer change.

The second is because the global average temperature change is less than the change at high latitudes, where most glaciers are found (Section 9.3.2).
