It is shown that the melting of ice floating on the ocean will introduce a volume of water about 2.6 per cent greater than that of the originally displaced sea water. The melting of floating ice in a global warming will cause the ocean to rise. If all the extant sea ice and floating shelf ice melted, the global sea level would rise about 4cm. The sliding of grounded ice into the sea, however, produces a mean water level rise in two parts; some of the rise is delayed. The first part, while the ice floats, is equal to the volume of displaced sea water. The second part, equal to 2.6 per cent of the first, is contributed as it melts. These effects result from the difference in volume of equal weights of fresh and salt water. This component of sea rise is apparently unrecognized in the literature to date, although it can be interpreted as a form of halosteric sea level change by regarding the displaced salt water and the meltwater (even before melting) as a unit. Although salinity changes are known to affect sea level, all existing analyses omit our calculated volume change.
Noerdlinger and Brower (2007)
Contrary to popular belief, the melting of floating ice (in the form of ice shelves, icebergs and sea ice) may have a non-zero impact on sea level. This is because the melting process cools and dilutes the oceans on average, and unless these opposing effects exactly balance each other there will be a net change in the ocean density. We discuss how these subtle effects can be quantified and put bounds on the potential sea level rise associated with melting of the ice masses that are currently afloat in the world's oceans.
Jenkins and Holland (2007)
According to this 743 km3/yr floating ice was lost in average between 1994 and 2004. They further conclude that 1.6% of current sea level rise (about 3.1 mm per year) is caused by loss of sea ice.

I received a invitation from Mobil Oil to go to their field in northern Sumatra for a interview. While there, I was at a drilling rig when my Mobil host said to me, "Ben, if we had a blowout on this rig tomorrow, we would be in big trouble communications wise trying to organize the specialist teams and put it out, that's why we want to go satellite.
That same day (Saturday), I flew back to Jakarta. On the Monday morning I was listening to the radio news when it was announced that a Mobil oil rig in Sumatra had a blow out and was on fire.Within days I received a call from Mobil offering me the job of getting a Satellite terminal installed asap.
Oh,.. and I took up the offer...and nah, I'm quite sure it wasn't MIHOP, the cost to put it out was huge and took three months.

Ok, so you read the article? What then do you think of Lean's analysis of the relative effects of increased solar irradiance as compared with the anthropogenic greenhouse gas component?

(If you were not aware, yes of course there are scientists who study the Sun and its influence on global climate and who think that Solar irradiance has a bigger contribution than CO2,...)
Ben wrote:Bph, no doubt Judith Lean has done lots of research and has published many papers, but the post in which I referenced her work that slim commented on is the extent of my knowledge and interest for now.
Judith Lean wrote:Claims that the Sun has caused as much as
70% of the recent global warming (based in part
on the attribution of radiometric trends to real solar
irradiance changes49) presents fundamental puzzles. It
requires that the Sun’s brightness increased more in the
past century than at any time in the past millennium,
including over the past 30 years, contrary to the direct
space-based observations. And it requires, as well,
that Earth’s climate be insensitive to well-measured
increases in greenhouse gases at the same time that it is
excessively sensitive to poorly known solar brightness
changes. Both scenarios are far less plausible than the
simple attribution of most (90%) industrial global
warming to anthropogenic effects, rather than to the
Sun.
Ben wrote:And speaking of Judith Lean, this is the last poster from Judith Lean's presentation at Nagoya University...
[UPDATE: West himself said during a Thursday conference call that global warming is at least partially man-made - and maybe as much as "70 percent" due to human intervention.

Here's the link again if you change your mind about wanting to understand the thoughts of the sources you cite:
http://www.agci.org/docs/lean.pdf
The attribution of present-day climate change, interpretation of changes prior to the industrial epoch, and forecast
of future decadal climate change necessitate quantitative understanding of how,
when, where, and why natural variability, including by the Sun, may exceed,
obscure or mitigate anthropogenic changes .

What say you, Wintler ?
One of the strangest things Ive noticed about you, is that for all your criticism of the Reptiles who control this ponzi debate, youve never once entertained the idea that these very same folks could be interfering with any serious attempts ( through alternative technologies) to actually improve things.
Instead, all that you, and a few of your minions have ever actually done is scream " it would never work", or "show me the proof"
Despite repeated efforts to show you the proof, and suggest that the billions levied in the ongoing ponzi scheme might be better addressed at some serious effort to assist in the development of exotic technology, Ive never once heard you speak in favour of such an idea.
Cutting to the quick here, this whole "Wintler supports the idea of AGW in his effort to save the planet" sounds to me like a bullshit cry from a bullshit salesman
There is, meanwhile, and Ive no doubt it surely hasnt escaped youre attention, an entire thread devoted to such suggestions of where our AGW taxes may be spent productively, instead of on wind farms and wave technology controlled by the usual assholes (which is where those taxes apparently go) You, of course, "mysteriously" have declined to address it.
Imagine my shock.

No correlation.
