This is especially true for lakes at high latitudes that are covered in ice each winter but may see less ice as temperatures rise.
«Ever since the lakes and seas were discovered, we've been wondering why they're concentrated at high northern latitudes,» said Elizabeth (Zibi) Turtle, a Cassini imaging team associate based at the Johns Hopkins Applied Physics Laboratory, Laurel, Md. «So, seeing that there's something special about the surface in this region is a big clue to help narrow down the possible explanations.»
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).
Also, if you look at Table T2 in this paper, you will see that ocean sea surface heat storage 0 - 700m from 1955 - 2003 (in W / m2) is always higher at northern latitudes than the corresponding southern latitudes in every case, even with the extensive Southern Ocean warming as noted by Gavin responding to # 18.
Keep in mind that north - facing slopes can see direct sun in early morning or late evening at higher latitudes.
I have analysed several climate model results and find that under a GW regime we would expect to see more record - breaking events at mid - to high latitudes and actually fewer new records than one would expect for the sub-tropics and where there is large - scale subsidence.
I have seen less data on North America and Europe, where in many regions, changes in the short term are likely to be beneficial, particularly at higher latitudes.
In response to increased trace gases, all replicated the qualitative response seen in other coupled ocean - atmosphere models: greater warming over land than ocean and maximum warming at high northern latitudes in winter.
See e.g. slide 31 of http://www.soest.hawaii.edu/GG/FACULTY/POPP/Lecture12.ppt E.g. a decreased insolation at high northern latitudes would cause ice sheets to grow.
Even when sea ice errors can be quantified, it is difficult to isolate their causes, which might arise from deficiencies in the representation of sea ice itself, but could also be due to flawed simulation of the atmospheric and oceanic fields at high latitudes that drive ice movement (see Sections 8.3.1, 8.3.2 and 11.3.8).
The models show large underestimates of CO at middle and high latitudes in the Northern Hemisphere, while typically performing reasonably well elsewhere (see figure).
UPDATE Ian Wilson's latest paper now addresses these questions, see link here http://landscheidt.auditblogs.com/2009/01/11/does-a-spin%E2%80%93orbit-coupling-between-the-sun-and-the-jovian-planets-govern-the-solar-cycle/ The Neptune, Uranus factor could be effecting the Sun is several ways, perhaps causing a slowdown in the rotational difference at the high and low latitudes thereby reducing the input to the solar dynamo.
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).
However, this phenomenon can not explain the mismatch to the other published proxy records clearly indicating warm climatic conditions in the High Northern Latitudes at that time (see discussion above).
However, at the higher latitudes, many locations are likely to warm by more than the global average (see figure).
This was an episode of rapid and intense warming (up to 7 °C at high latitudes) which lasted less than 100,000 years (see Figure 1).
Anomalies in the volcanic - aerosol induced global radiative heating distribution can force significant changes in atmospheric circulation, for example, perturbing the equator - to - pole heating gradient (Stenchikov et al., 2002; Ramaswamy et al., 2006a; see Section 9.2) and forcing a positive phase of the Arctic Oscillation that in turn causes a counterintuitive boreal winter warming at middle and high latitudes over Eurasia and North America (Perlwitz and Graf, 2001; Stenchikov et al., 2002, 2004, 2006; Shindell et al., 2003b, 2004; Perlwitz and Harnik, 2003; Rind et al., 2005; Miller et al., 2006).
It is seen that the zero phase difference line approaches high latitudes in winter and moves to middle, even tropical latitudes during summer at both hemispheres.
Furthermore, it can be seen that due to the lower incidence angle of the solar radiation at lower latitudes, TEC at 35 ° N is principally higher than TEC at 65 ° N. Differences between both latitudes are always positive at day - time and reach up to 20 TECU while following the solar cycle dynamics.
Figure 2 - B suggests that since 1979 there has been a jump of at most 0.3 °C during the great El Niño of 1997 - 98; (see figure 15 - A showing that El Niño paces the global temperatures as the water of the warm pool is redistributed to the oceanic surface layer at higher latitudes).
From CO2 estimate like this, we don't see that Antarctic glaciation 35 million years ago could have occurred at much more than 800 ppm, and the much higher CO2 levels before that were even favorable for forests at polar latitudes.
In that event, figure 7 suggests a global mean warming approaching 25 °C, with much larger warming at high latitudes (see electronic supplementary material, figure S6).
Did you ever see much forest growth at higher altitudes and latitudes where is is very cold?
In principle a similar situation could arise at lower latitudes at high elevations in the Rocky Mountains, although most models project a widespread decrease of snow depth there (Kim et al., 2002; Snyder et al., 2003; Leung et al., 2004; see also Box 11.3).
As can be seen, coverage at high latitudes during winter is poor mainly because the sun is not high enough over the horizon.
This implies that future ocean warming may likewise see greater warming rates (at some point), in the deep ocean and higher latitudes, than the equatorial regions.
When I look at global temperature anomaly maps put out by NASA, I see that the most dramatic warming is occurring in the high northern latitudes (in places like Alaska, Siberia, and Greenland).
Anomalies in the volcanic - aerosol induced global radiative heating distribution can force signifi cant changes in atmospheric circulation, for example, perturbing the equator - to - pole heating gradient (Stenchikov et al., 2002; Ramaswamy et al., 2006a; see Section 9.2) and forcing a positive phase of the Arctic Oscillation that in turn causes a counterintuitive boreal winter warming at middle and high latitudes over Eurasia and North America (Perlwitz and Graf, 2001; Stenchikov et al., 2002,2004, 2006; Shindell et al., 2003b, 2004; Perlwitz and Harnik, 2003; Rind et al., 2005; Miller et al., 2006).
