I compared current arctic ice coverage area with the last ten years.

Not exact matches

The island, which had detached itself from the ice shelf on Ellesmore Island in the Canadian arctic archipelago, was used as a laboratory for seismic studies of the Arctic Ocean floor, as well as charting currents, pollution, winds and ice structure.

Seems this might hold for larger scale events, such as the arctic ice melting (i.e., there would be more warming in the arctic ocean in our current times, except some of the «warming» energy is going into the melting process rather than warming).

The rise of CO2 from 270ppm to now over 400ppm, the extent of equatorial and sub tropical deforestation, the soot deposits on the polar ice caps, the increase in atmospheric water vapour due to a corresponding increase in ocean temps and changes in ocean currents, the extreme ice albedo currently happening in the arctic etc, etc are all conspiring in tandem to alter the climate as we know it.

Extremely pessimistic overview of current arctic sea ice formation and disintegration processes and the current sea ice state.

There are a lot of graphs there and elsewhere, but watching this satellite sequence give some indication of how the recent, and current, — emergent cyclones have caused the ice to break up spread out, and melt in warmer (by arctic standards) water.

Monbiot, unlike Kleiman, makes some attempt at a reasoned rebuttal of Wills, with four points (really three: on the global cooling hysteria, arctic ice disappearance, and the current absence of global warming).

This grim fact is even bleaker if the international community concludes that it should limit warming to 1.5 degrees C, a conclusion that might become more obvious if current levels of warming start to make positive feedbacks visible in the next few years such as methane leakage from frozen tundra or more rapid loss of arctic ice.

When we get a arctic season with great cyclones, those cyclones can lead to a break up of the ice (more lateral melting), If currents conspire we end up with more transport out of the arctic (ice then melts in the warmer water), and we get Eckmen pumping and more ice melts.

LIA wasn't GLOBAL cooling; but colder in Europe, north America — because Arctic ocean had less ice cover - > was releasing more heat / was accumulating - > radiating + spreading more coldness — currents were taking that extra coldness to Mexican gulf — then to the Mediterranean — because Sahara was increasing creation of dry heat and evaporating extra water in the Mediterranean — to top up the deficit — gulf stream was faster / that was melting more ice on arctic also as chain reaction — Because Mediterranean doesn't have enough tributaries, to compensate for the evaporation deficit.

The arctic is mostly ocean covered by ice, so warm water currents could be bringing in heat.

On current trends, we will see the first ice free arctic summer (90 days ice free) in 2016; 2017 at the latest.

I am actually not aware why the atlantic overturning (conveyor) should be sensitive to altered wind patterns in the long run, provided that they does not significantly weaken the Antarctic circumpolar current or amplify arctic ice cover.

Given that arctic sea ice is already set to disappear given current levels of GHGs in the atmosphere, there is little chance that this feedback will contribute to an ice age any time in the foreseeable future.

The constant flow of relatively warmer surface water that started in the mid 60s from the equitorial atlantic produced a net increase in arctic ice melt, thus a colder southward current in the E Atlantic, giving the wrong impression of generalised cooling in the region.

«The constant flow of relatively warmer surface water that started in the mid 60s from the equitorial atlantic produced a net increase in arctic ice melt, thus a colder southward current in the E Atlantic»

According to his research it's only solid on the surface beneath that it's completely «rotten», indicating to me that the warmer arctic ocean currents are contributing far more to the arctic ice loss that air temps.
