Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when
ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
This causes increased erosion due to permafrost melt, increased flooding due to the warmer temperatures, and intensified storms because the sea
ice forms later in the season and is unable to provide a natural barrier for our coastal communities.
When the sea -
ice forms later in the year, the freezing process rejects brine and thus the resulting sea - ice has a lower salt content than the surface water below.

Theoretical modelling indicate that a hot steam planet could
form if it

late to accrete a large hydrogen - helium gas envelope.

We might have a saviour in the
form of the growing antarctic
ice sheets in the southern winter as this causes much more planckton to

Despite stating that there is no CO2 data near the time of the Devonian glaciation [there are values of 1000ppm and 1300ppm before and after the glaciation], and surmising that perhaps 2000ppm CO2 would be low enough to allow permanent
ice to
form the graph shows a value of below 500ppm for the
late Devonian.
I have alluded to Phillips» opinion, because I see in Geikie's
late work that reference is made to the fact that from the foot of glaciers in Greenland streams of water issue and unite to

ice.
