Anyone
at high latitudes makes far less vitamin D per minute of sun exposure.
Nowadays only the sea surface warming expressed by Endersbee seems to make higher portions of manmade CO2 in atmosphere possible, as the warming of the as sinks acting sea surfaces
at the higher latitudes makes absorption of CO2 from the atmosphere become slower.

The most recent news
making events are two: a challenge to the dates that have been assigned to Neanderthal remains closest to the time of their extinction; and a claim Neanderthals occupied a site in the Siberian far North,
at much
higher latitudes than previously thought possible.
This
makes it possible for the Sun to rotate faster
at its equator (about 25 days) than it does
at higher latitudes (about 35 days near its poles).
That they could bask in the sun merely confirms what these scientists have long suspected: that Earth's
high latitudes are warming dangerously thanks to man -
made climate change, with temperatures rising
at twice the global average.
If I understood Armour's paper correctly, he claimed that all feed - backs were close to linear in response to temperature over time, but that different regional warming rates (specifically, slow warming
at high latitudes) could
make the feed - backs and sensitivity appear to increase with time.
Mosher mentioned that there are larger siting issues are
at the
higher latitudes which
makes sense.
In this particular case, the multiple timescale issue arising from slow mixing
at higher latitudes seems to
make any analysis with a linear dependence on global mean surface temperature suspect.
So the factor of two arises because of cancellations of the contributions from lower
latitudes,
making the relatively small adjustments
at high Arctic regions relatively more important.
The warming in surface temperatures
at higher latitudes, as described in this study, are firmly ascribed to man -
made climate change by the IPCC (Intergovernmental Panel on Climate Change).
