The shift provides additional evidence that changes in the Arctic are not only directly because of global warming, as shown by
warmer air and sea temperatures, but are also part of an «Arctic amplification» through which multiple Arctic - specific physical processes interact to accelerate temperature change, ice variability, and ecological impacts.

The researchers identified several key circulation patterns that affected the winter temperatures from 1979 to 2013, particularly the Arctic Oscillation (a climate pattern that circulates around the Arctic Ocean
and tends to confine colder
air to the polar latitudes)
and a second pattern they call
Warm Arctic

sea ice loss as well as to particularly strong winters.
Mori et al. identified two circulation patterns that drove winter temperatures in Eurasia from 1979 to 2013: the Arctic Oscillation (which confines colder

Other factors would include: — albedo shifts (both from ice > water,
and from increased biological activity,
and from edge melt revealing more land,
and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing,
and increasingly
warm, rain fall on ice; — «stuck» weather systems bringing more
and more
warm tropical
air ever further toward the poles; — melting of
sea ice shelf increasing mobility of glaciers; —
sea water getting under parts of the ice sheets where the base is below
sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)
due to co2 we are already living in a greenhouse.Whatever one does in that greenhouse will remain in the greenhouse.INDUSTRIOUS HEAT will remain in the greenhouse instead of escaping into outer space; this is a far greater contributor to global
warming than other factors
and far more difficult to reduce without reducing economic activity.Like
warm moist
air from your mouth on cold mornings so melting antarctic ice will turn into cloud as it meets
warm moist
air from tropics the
seas will not rise as antarctica is a huge cloud generator.A thick band of cloud around the earth will produce even temps accross the whole earth causing the wind to moderate even stop.WE should be preparing for this possible scenario»

It appears to me that the family of humanity is beginning to come face to face with a myriad of growing global challenges —
air pollution,
sea and land contamination, global
warming, peak oil, diminishing global supplies of grain, overfishing, the dissipation of Earth's scarce resources, desertification, deforestation, urban sprawl
and autoban congestion are examples — the sum of which could soon become unsustainable, given a finite planet with the relatively small size
and make - up of Earth.

Think of what would happen if you could pump cold deep water up to the surface, increasing the

Excerpt: Livermore CA (SPX) Nov 01, 2005 If humans continue to use fossil fuels in a business as usual manner for the next several centuries, the polar ice caps will be depleted, ocean
sea levels will rise by seven meters

warmer than current day.
% due to eruption 9.5 % (assuming the average thickness of melted ice was 1 meter,
and not allowing for any of the heat being lost to

air, or evaporation)
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).
Warming of the climate system is unequivocal, as is now evident from observations of increases in global average

Based on the results of the causality tests, the author concludes that it is global near - surface
air temperature that influences
sea surface temperature,
and not the other way around — which supports the global
warming - induced increase in hurricane intensity.
