8d) correspond to a reinforcement of the climatological poleward
heat flux, which was shown to lead to a weakened polar vortex (Polvani and Waugh 2004; Dunn-Sigouin and Shaw 2015; Shaw et al.
They found that in the Northern Hemisphere, the storms are moving polewards
at a rate of 53 kilometres per decade, and in the Southern Hemisphere, at a rate of 61 kilometres per decade.
Such trends could indicate a poleward
shift in range for both species (MacLeod et al.
Scientists say climate change is already visible in sea-level rise, loss of alpine glaciers and snow cover, shrinking Arctic summer sea ice, thawing permafrost, poleward
migration of animals and plants and an increase in intense tropical cyclone activity in the North Atlantic.
While the more poleward
positioning of the high pressure cores does bring colder air northwards, it also pushes significantly warmer air deep into the temperate climate zone, even to the edges of the polar, frigid, airmass.
SOLRAD also revealed a poleward
gain of solar radiative flux which could have facilitated the observed polar amplification of global warming.
shifts in breeding bird distributions in New York State, Global Change Biology 15: 1866-1883.
It's the heating of the mid-latitudes that pushes the boundaries of the tropics poleward
The response of two butterfly species to climatic variation at the edge of their range and the implications for poleward
of 30[degrees] latitude, decreasing smoothly to 0.
These range shifts have generally been poleward
and upward (toward higher elevations) (Hickling et al.
Darwin speculated that species migration in response to climate change had proceeded in an orderly manner and that entire communities had shifted poleward
together as a unit (Darwin, 1859).
However, the further poleward
you live, dark skin preventing maternal vitamin D production becomes an increasingly significant risk (actor for schizophrenia.
In addition toy--or instead of--adjusting life cycle timing, some organisms have responded to warming temperatures by shifting their geographical ranges, often poleward
While these areas could experience more droughts, the expansion of the tropical zone into former subtropical regions could result in heavier rainfall and flooding, with a possible poleward
shift in the paths of extra-tropical and tropical cyclones over the next 100 years.
