Further to Greenland's current warming & melting glacier's, I bring you this analysis of a paper published in Nature Geoscience:
model simulations show that "ice acceleration, thinning and retreat begin at the calving terminus and then propagate upstream through dynamic coupling along the glacier." What is more, they find that "these changes are unlikely to be caused by basal lubrication through surface melt propagating to the glacier bed," which phenomenon is often cited by climate alarmists as a cause of great concern with respect to its impact on sea level.
Nick et al. conclude that "tidewater outlet glaciers adjust extremely rapidly to changing boundary conditions at the calving terminus," and that their results thus imply that "the recent rates of mass loss in Greenland's outlet glaciers are transient and should not be extrapolated into the future [italics added]." And if this advice is followed, the extreme sea-level-rise scenarios promoted by the alarmists, such as Gore and Hansen, fail to materialize.
Kinda like a dam on a river, huh? You dam the water, it backs up. The dam breaks, the backed up water flows. Yeah, the ice is a bit more dense but same principle.
Word watch: We've seen the abject failure of the term "Global Warming" as temperatures cooled. This gave way to the second abject failure of "Climate Change," a ludicrously neutral term on which everyone can agree--climate changes, so what? The new one creeping around is "Global Weirding" in which almost every notable weather event is branded an inexplicable anomaly. Nice to see such despair in action on the PR front.
OK, so some warmists are stuck in the last hunnert years, ignoring any data older than that & completely missing factors which have periodicities much greater than a century.
Fine. We got that covered, too.
In this analysis the authors have been able to provide evidence that the mid 20th century had far more extreme conditions than any subsequent time:
The two researchers report that with respect to all discrete five-year periods (pentads) between 1950 and 2004, "the 2000-04 pentad has the second longest mean predicted melt duration on Novaya Zemlya (after 1950-54), and the third longest on Svalbard (after 1950-54 and 1970-74) and Severnaya Zemlya (after 1950-54 and 1955-59) [italics added]," which findings clearly reveal the 1950-54 pentad to have experienced the longest melt season of the past 55 years on all three of the large Eurasian Arctic ice caps.
In spite of almost everything we have heard from climate alarmists over the past two decades about global warming becoming ever more intense, especially in the Arctic, conditions during the middle of the past century seem to have been even more extreme in this respect than they have been at any subsequent time, especially on these three major ice caps and their associated glaciers.
Holy smokes, take a day off, galavantin' all over the province, free lunch from a fellow artist/photographer (thank you again!), beer & BS, gossiping about ehMac & the research world explodes!
Background: When I was in university, I had the privilege of taking a couple of topics courses from Archie Stalker, now deceased & formerly of the Geological Survey of Canada (fantastic Quaternary scientist). He was the kind of old school, hands on researcher that would tell you to lick you finger & stick it in the sediment you analyzing, then place it in your mouth & feel the texture. You could always tell if the sample was a paleosol, a lacustrine sediment, a clay or something else just by putting it in your mouth. Very cool.
He had personally hiked & mapped more of southern Alberta than anyone else before or since. Hard to keep up with him, even at 65.
At any rate, soils. A brief analysis of a paper published in Quaternary Research wherein the authors analyze soils in the Italian Alps & conclude that the Roman Warm Period & the Medieval Warm Period were both warmer & longer than the current warming period.
Among a number of other interesting findings, Giraudi determined that between about 200 BC and AD 100 -- i.e., during the Roman Warm Period -- "soils developed in areas at present devoid of vegetation and with permafrost," indicative of the likelihood that temperatures at that time "probably reached higher values than those of the present [italics added]." He also concluded that "analogous conditions likely occurred during the period of [the] 11th-12th centuries AD, when a soil developed on a slope presently characterized by periglacial debris," while noting that "in the 11th-12th centuries AD, frost weathering processes were not active and, due to the higher temperatures than at present [italics added] or the longer duration of a period with high temperatures [italics added], vegetation succeeded in colonizing the slope." He also determined that "the phase of greatest glacial expansion (Little Ice Age) coincides with a period characterized by a large number of floods in the River Po basin," and that "phases of glacial retreat [such as occurred during the Roman and Medieval Warm Periods] correlate with periods with relatively few floods in the River Po basin."
This study provides a double refutation of the climate-alarmist claim that late 20th-century temperatures were the warmest of the past two millennia. And it demonstrates that in this part of Europe, cooler periods have generally experienced less flooding than have warmer periods.
Italics from the analysis, bold mine.
Also wanted to give credit where credit is due:
In a sense, I'm glad all these warmists have come out with their claims about AGW. The opportunity provided has been a wonderful impetus to research the truth about the complexity of global warming & all the natural causes & cycles contained therein.
moving past the google wars and it's google link duels.
It seems the much celebrated anti climate change champion and scientist, is in a heap of trouble, once again.
Andrew Weaver Sues Tim Ball for Libel
University of Victoria Professor Andrew Weaver, the Canada Research Chair in Climate Modelling and Analysis, has filed suit for libel against freelance climate change denier Tim Ball.
The suit (attached below) arises from an article that Ball penned for the right-wingy Canada Free Press website, which has since apologized to Weaver for its numerous inaccuracies and stripped from its publicly available pages pretty much everything that Ball has ever written.
In the article, Ball, a former geography professor at the University of Winnipeg with an indifferent academic record and a lifetime peer-reviewed literature output of just four articles (none of them in atmospheric physics), assailed Weaver as uninformed about climate, unqualified to teach and compromised by his lavish funding, accusations for which he offered no proof whatever.
Weaver, a member of the Royal Society of Canada who has authored more than 190 papers, was also a lead author on three of the four reports of the Intergovernmental Panel on Climage Change (IPCC), and is lined up as a lead author on the fifth. He's also won pretty much all the academic and teaching awards that are available to a Canadian professor who has not yet had his 50th birthday. Ball, famously slow to notice the obvious, apparently didn't realize that he was overmatched.
Of course, it's not the first time. Ball sued University of Lethbridge Professor Dan Johnson in October 2006 over imagined slights in a letter to the editor that Johnson had written to the Calgary Herald. When both Johnson and the Herald filed a devastating Statements of Defence, Ball turned tail and ran.
But regardless that the suit had exposed the numerous falsehoods that once coloured Balls resume - and regardless that a University of Calgary audit confirmed that Ball had been accepting money that had been sluiced through a university slush fund that had been set up to conceal the money's oil industry origins, Ball has continued to write and speak, claiming some higher knowledge of the workings of climate change - actually, of the lack of climate change.
Just one more crack in the warmists theory of AGW causing severe weather. It apparently doesn't.
Magnetic Polar Shifts Causing Massive Global Superstorms
Superstorms can also cause certain societies, cultures or whole countries to collapse. Others may go to war with each other.
(CHICAGO) - NASA has been warning about it…scientific papers have been written about it…geologists have seen its traces in rock strata and ice core samples…
Now "it" is here: an unstoppable magnetic pole shift that has sped up and is causing life-threatening havoc with the world's weather.
Forget about global warming—man-made or natural—what drives planetary weather patterns is the climate and what drives the climate is the sun's magnetosphere and its electromagnetic interaction with a planet's own magnetic field.
When the field shifts, when it fluctuates, when it goes into flux and begins to become unstable anything can happen. And what normally happens is that all hell breaks loose.
Magnetic polar shifts have occurred many times in Earth's history. It's happening again now to every planet in the solar system including Earth.
The magnetic field drives weather to a significant degree and when that field starts migrating superstorms start erupting.
The superstorms have arrived
The first evidence we have that the dangerous superstorm cycle has started is the devastating series of storms that pounded the UK during late 2010.
