Nearly 99 percent of them outside Antarctica reside in sediments along continental slopes, more than 500 meters underwater in midlatitudes, 300 meters in higher latitudes.
Sunsets occur more quickly near the equator than at higher latitudes, so the green flash is a shorter phenomenon in the tropics.
It needs to be clarified here, that it is hypothetically possible to get more snowfall and snowpack in a globally warming world (at least for a while), due to increased precipitation (which is predicted in a warming world, esp for the higher latitudes) coming down as snow.
In terrestrial d18O records, the precipitation patterns, timing and sources are important — more so in the tropics than at high latitudes though.
There are also numerous «fingerprints» which we would expect to see from an increased greenhouse effect (i.e. more warming at night, at higher latitudes, upper atmosphere cooling) that we have indeed observed (Figure 6).
For example, an open Northwest Passage, enhanced growth for some plants and improved agriculture at high latitudes (though this will require use of more fertilizers), etc..
With higher precipitation, portions of this snow may not melt during the summer and so glacial ice can form at lower altitudes and more southerly latitudes, reducing the temperatures over land by increased albedo as noted above.
Furthermore, the relatively high «sensitivity» from glacial to interglacial is largely driven by the change in the orbit relative to the Sun, which changes the distribution of incident solar energy into the system quite dramatically (more energy is distributed to the higher latitudes in the NH summer, in particular).
Hansen does show support for our statements that the recent warming experienced in the Midwest is much more likely to occur in winter than summer due to «the huge difference of temperature between low latitudes and high latitudes in winter.
These kinks and twists in the magnetic field develop because the sun spins more rapidly at the equator than at the higher latitudes and because the inner parts of the sun rotate more quickly than the surface.
The high latitudes and polar regions were more or less ice - free, and were populated by a diverse assemblage of plants and animals.
However, the clustering of extragalactic, extreme ultraviolet sources at high galactic latitudes was consistent with one hypothesis that the Local Bubble may actually be part of a cylindrical cavity that pierces the galactic, dubbed the «Local Chimney» (Welsh et al, 1999; and more discussion from CHIPS).
With the more recent understandings of the ways reduced sunlight affects many people, bringing to our attention extreme reactions, such as SAD (Seasonal Affective Disorder) and high rates of suicide in latitudes of Earth that have fewer annual days / hours of sunlight, we now have support for Lessing's «far - fetched» propositions.
Dogs living at high altitudes and low latitudes are more severely affected.
When it is assumed that the CO2 content of the atmosphere is doubled and statistical thermal equilibrium is achieved, the more realistic of the modeling efforts predict a global surface warming of between 2 °C and 3.5 °C, with greater increases at high latitudes.
Samples of gas trapped in ice cores taken from the Greenland and Antarctic ice sheets have enabled scientists to determine that the level of CO2 in the atmosphere has fluctuated between approximately 180 ppm (glacial advance and colder climate in the higher latitudes) and 280 ppm (glacial retreat and warmer climate in the higher latitudes), over the past 400,000 or more years.
In the future, there will be more precipitation in the mid-latitudes and less in the high latitudes of the NH.
Vigorous convective mixing in the deep tropics also dilutes changes in near - surface CO2 much more than at higher latitudes, so low - altitude sampling contains relatively less information about carbon sources and sinks.
The Eemian forcing is ~ 40 W / m2 in summer high - latitudes, order of magnitude more than that of doubled CO2 globally.
The second possibility, as feedback to higher sea surface temperatures, seems also more sensitive for solar in the tropics than for GHGs in the higher latitudes...
I think GW will cause more WV & precip, esp in the higher latitudes.
In the future, there will be more precipitation in the high latitudes of the NH and less precipitation in the mid-latitudes.
In that case (along with greater precipitation, and the precipitation belt moving to higher latitudes), there could be more snow in the winter & greater melting in the summer (in higher latitudes), while I'd think the lower latitudes (with less precip) and the local mean temp being higher, would melt the glaciers faster, without adequate snowfall & low winter temps to slow this glacial decrease.
So in Greenland it got warmer both because of higher CO2, more sunlight at high latitudes during summer, AND because of increased poleward heat flow.
Warmer temperatures at high latitudes are already resulting more frequent Arctic fires, and unprecedented permafrost thaw is leaving large soil carbon pools exposed to smoldering fires for the fist time since ancient times.
I was thinking instead perhaps more easily controlled polar - orbit satellites might be used, which would rotate with some fixed ratio to their orbital period, casting greater shadows at higher latitudes... or some other arrangment... for a targetted offset polar amplification of AGW especially and in particular perhaps avoiding the reduction in precipitation that can be caused by SW - radiation - based «GE» (although aerosols that actually absorb some SW in the troposphere while shielding the surface would have the worst effect in that way, I'd think)... strategic distribution of solar shading has been suggested with precipitation effects in mind, such as here... sorry, I don't have the link (I'm sure I saved it, just as Steve Fish would suggest — but where?).
In continental locations, and at high latitudes, it will be more.
«Yes, sea ice seems to behaving as the consensus of the climate models have been projecting — more rapid and larger response in the northern high latitudes than anywhere else, flat to possible increase in [southern hemisphere] sea ice as warming takes hold,» he wrote.
Actually, there is some interesting work being done by Matt Huber of Purdue, following up on some earlier ideas of Emanuel's, suggesting that the role of TCs in transporting heat from equator towards the poles may be more significant than previously thought — it also allows for some interesting, though admittedly somewhat exotic, mechanisms for explaining the «cool tropics paradox» and «equable climate problem» of the early Paleogene and Cretaceous periods, i.e. the problem of how to make the higher latitudes warm without warming the tropics much, something that appears to have happened during some past warm epochs in Earth's history.
(57j) For surface + tropospheric warming in general, there is (given a cold enough start) positive surface albedo feedback, that is concentrated at higher latitudes and in some seasons (though the temperature response to reduced summer sea ice cover tends to be realized more in winter when there is more heat that must be released before ice forms).

This dependency to physical conditions is evident from how the temperature and precipitation vary from place to place: typically warmer at low latitudes and cooler at higher altitudes; more rain near the coast and less in the interior.

and there's a lot of basic physics that stem from simple principles (e.g., precipitation is more depleted than the water from which it evaporated, the high latitudes are more depleted than lower latitudes, etc).
It is not that the polar regions are amplifying the warming «going on» at lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»
Now if «global» surface temperature anomaly correlated most strongly with the poles or the northern mid to high latitudes, I might tend to be more in the CO2 as the dominate forcing camp, but such is not the case.
