There is some speculation that global warming could, via a shutdown or slowdown of the thermohaline circulation, trigger localised cooling in the North Atlantic and lead to cooling, or lesser warming, in that region.

Global warming is desiccating the region in two ways: higher temperatures that increase evaporation in already parched soils, and weaker winds that bring less rain from the Mediterranean Sea during the wet season (November to April).

On the other hand, if the ice shell is sufficiently thick, the less intense interior heat can be transferred to warmer ice at the bottom of the shell, with additional heat generated by tidal flexing of the warmer ice which can slowly rise and flow as do glaciers do on Earth; this slow but steady motion may also disrupt the extremely cold, brittle ice at the surface to produce the chaos regions.

In his seminal 1982 book Climate, History, and the Modern World, the renown climatologist Dr. H.H. Lamb revealed that sea ice in the subarctic and Arctic regions was much less extensive during the Medieval Warm Period (9th - 13th centuries) compared to today.

«Glaciers in higher colder mountainous regions will be slower to melt even as temps rise, the lower tundra areas will respond more quickly to such changes and this is shown by the quicker responses in tree line to the lesser warming periods like the MWP at ground level further north from him, and not just fossil remains but old farming settlements uncovered, and so on.»

With some exceptions, the tropics will likely receive less rain (orange) as the planet warms, while the polar regions will receive more precipitation (green).

Because it is compressed into the warmest region, biodiversity currently appears to be limited by less then optimal, too cool temps.

But on the other hand, according to the study, the so - called «dynamical» influence of warming will alter that basic assumption and instead cause more rain in some regions and less or no rain in others.

One study estimates that there are likely to be places on Earth where unprotected humans without cooling mechanisms, such as air conditioning, would die in less than six hours if global average surface temperature rises by about 12.6 ° F (7 ° C).16 With warming of 19.8 - 21.6 ° F (11 - 12 ° C), this same study projects that regions where approximately half of the world's people now live could become intolerable.7

And, in fact, the data shown at CO2science provide evidence for exactly the reason why the current warmth ends up being less extreme than the modern warmth: For the modern warmth, the warming of different regions is largely in synch.

Polar bears are one of the most sensitive Arctic marine mammals to climate warming because they spend most of their lives on sea ice.35 Declining sea ice in northern Alaska is associated with smaller bears, probably because of less successful hunting of seals, which are themselves ice - dependent and so are projected to decline with diminishing ice and snow cover.36, 37,38,39 Although bears can give birth to cubs on sea ice, increasing numbers of female bears now come ashore in Alaska in the summer and fall40 and den on land.41 In Hudson Bay, Canada, the most studied population in the Arctic, sea ice is now absent for three weeks longer than just a few decades ago, resulting in less body fat, reduced survival of both the youngest and oldest bears, 42 and a population now estimated to be in decline43 and projected to be in jeopardy.44 Similar polar bear population declines are projected for the Beaufort Sea region.45

You have no grounds for assuming this unless you can produce temperature data evidence that the most predominant greenhouse gas water vapour makes moist regions considerably warmer than dry regions where there may be less than 25 % as much water vapour.

CO2 saves water, grows more food on less water, makes t warmer at night reducing frost damage, supposedly warms the polar regions more then the tropics and sub tropics, creating less energy to drive extreme weather.

Shifts in clouds, water vapor, and the great currents in the ocean and air, however, cause complex responses in which some regions warm more than the average while others warm less than average, or even cool.

As the world warms, the locations of these interactions will shift in space and time, bringing more severe conditions to some regions and less extreme conditions to others.

As expected, amounts of precipitable water are greatest over warm, equatorial regions and decrease more or less continuously with increasing latitude down to very low values over the cold, polar regions.
