Its core is a flurry of recent research proposing that such extreme weather events in the midlatitudes are linked through the atmosphere with the effects of rapid climate change in the Arctic, such as dwindling sea ice.
The team's next steps include looking more closely at specific ocean swell events and sea ice conditions during known ice shelf collapses and large iceberg calving events.
The impacts of climate change include global warming, rising sea levels, melting glaciers and sea ice as well as more severe weather events.
«Although we haven't been able to detect a strong El Niño impact on Arctic sea ice yet, now that the ice is thinner and more mobile, we should begin to see a larger response to atmospheric events from lower latitudes.»

And on the opposite side of the planet, on March 3 sea ice around Antarctica hit its lowest extent ever recorded by satellites at the end of summer in the Southern Hemisphere, a surprising turn of events after decades of moderate sea ice expansion.
It's unclear whether this year's strong El Niño event, which is a naturally occurring phenomenon that typically occurs every two to seven years where the surface water of the eastern equatorial Pacific Ocean warms, has had any impact on the Arctic sea ice minimum extent.
«This year is the fourth lowest, and yet we haven't seen any major weather event or persistent weather pattern in the Arctic this summer that helped push the extent lower as often happens,» said Walt Meier, a sea ice scientist with NASA's Goddard Space Flight Center in Greenbelt, Maryland.
«Sea ice is critical for Arctic marine mammals because events such as feeding, giving birth, molting, and resting are closely timed with the availability of their ice platform,» Laidre said.
What's happening in the Arctic would be impossible without a century of global warming causing a long - term decline in sea ice levels — but it is actually a short - term weather event.

We emphasize that because of the significant influence of sea ice on the climate system, it seems that high priority should be given to developing ways for reconstructing high - resolution (in space and time) sea - ice extent for past climate - change events.
If proxy data can confirm that sea ice was indeed the major player in past abrupt climate - change events, it seems less likely that such dramatic abrupt changes will occur due to global warming, when extensive sea - ice cover will not be present.
Because of the warming, «there are some potentially catastrophic events that must be considered,» including sea level rise from melting polar ice sheets, according to the document.
Even if you ignore all the temperature meauserments which you seem to vehimently deny there is still many other sources of evidence associated with this increase such as — ice melt / extreme weather events / sea current changes / habitat changes / CO2 / ice cores / sediment cores.
A team of researchers has learned that the powerful 1997 - 98 El Niño event dramatically accelerated the melting of the ice shelves buttressing glaciers in West Antarctica's Amundsen sea sector.
Overall, ice shelves in the Amundsen sea sector lost about five times as much mass as they gained during the event.
Anderson, J.B. and Thomas, M.A., 1991, Marine ice sheet decoupling as a mechanism for rapid, episodic sea - level change: the record of such events and their influence on sedimentation: Sedimentary Geology, v. 70, p. 87 - 104.
«Arctic sea ice destruction; blue ocean event and global food supply threat.»
«Sea ice status now; projection for rest of melt season, implications to extreme weather events and global food supply.»
And while some events, like the U.S. winter storms and the record high Antarctic sea ice extent, could be pinned to a particular cause, that cause could not be linked to climate change.
The latter events left behind distinctive rock - sequences typically consisting of tillites (ancient boulder - clay, now solid rock) representing ice - deposited debris, overlain with a depositional break by cap - carbonates (chemical sediments of marine origin deposited during interglacials following global sea - level rises).
•» Hence, both regional and local sea - level rise and fall in meter - scale is related to the geologic events only and not related to global warming and / or polar ice melt.»
If proxy data can confirm that sea ice was indeed the major player in past abrupt climate - change events, it seems less likely that such dramatic abrupt changes will occur due to global warming, when extensive sea - ice cover will not be present.
We emphasize that because of the significant influence of sea ice on the climate system, it seems that high priority should be given to developing ways for reconstructing high - resolution (in space and time) sea - ice extent for past climate - change events.
During Heinrich Events, there seems to have been simultaneous ice surges in North America, Scandinavia and possibly Antarctica, which can be explained if you accept that sea level rise from one surge will cause the other ice sheets to surge as well.
When this occurs in ice sheets containing half a million (or more) cubic kilometers of ice; then, there is a sea level rise event.
eg Graham explained that these warming events are related to the decline of winter sea ice in the Arctic, noting that January's ice extent was the lowest on record.
When the ice sheets start progressive structural collapses we will see sea level rise events.
Periods that are of possibly the most interest for testing sensitivities associated with uncertainties in future projections are the mid-Holocene (for tropical rainfall, sea ice), the 8.2 kyr event (for the ocean thermohaline circulation), the last two millennia (for decadal / multi-decadal variability), the last interglacial (for ice sheets / sea level) etc..
Now to contribute a single event to Global Warming, one has to look at the weather conditions, and if patterns are sighted which are tied to alteration of sea ice decline (our new atmosphere set up), we can connect the dots here too.
These parameters include global mean surface temperature, sea - level rise, ocean and ice sheet dynamics, ocean acidification, and extreme climatic events.
These patterns, however, differ from the corresponding patterns in the historical period, and underline the connection between European cold winter events and Arctic sea ice reduction.
That these «events» should have a corresponding counter event is what concerns me wrt polar sea ice melt.
Our analyses of sea ice suggest such events will happen and likely much sooner than expected in Hudson Bay.
It seems increasingly clear that D - O events must involve major sea ice changes (and there is not much sea ice left, by comparison with what was present during the glacial period (20000 + years ago, when these events happened), so D - O events are increasingly unlikely in the future).
I've been criticized by some environmentalists in recent years for writing that the long - term picture (more CO2 = warmer world = less ice = higher seas and lots of climatic and ecological changes) is the only aspect of human - caused global warming that is solidly established, and that efforts to link dramatic weather - related events to the human influence on climate could backfire should nature wiggle the other way for awhile.
I would be more than happy to see a tidal chart showing an estreme anomaly in sea level at thesame moment as with observed tidal ice events, but the charts I've seen show 100 cm tides even at the full moon.
