No, no, I will. It looks like there's collectively a decent amount of papers and thoughts, and it's been quite a while since I refreshed my knowledge on the topic.
Mainly though I want to see the reasoning for how global warming is going to shift the tectonic plates and cause more earthquakes and volcanoes. Sounds like a fascinating twist, on what is otherwise a fairly straightforward concept.
Have you got the land ice chart?

Is Antarctica losing or gaining ice?

The skeptic argument...
Antarctica is gaining ice
"[Ice] is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap." (Greg Roberts, The Australian)
Satellites measure Antarctica is gaining sea ice but losing land ice at an accelerating rate which has implications for sea level rise.
Skeptic arguments that Antarctica is gaining ice frequently hinge on an error of omission, namely ignoring the difference between land ice and sea ice.
In glaciology and particularly with respect to Antarctic ice, not all things are created equal. Let us consider the following differences. Antarctic land ice is the ice which has accumulated over thousands of years on the Antarctica landmass itself through snowfall. This land ice therefore is actually stored ocean water that once fell as precipitation. Sea ice in Antarctica is quite different as it is ice which forms in salt water primarily during the winter months. When land ice melts and flows into the oceans global sea levels rise on average; when sea ice melts sea levels do not change measurably.

Readers - There is actually a useful lesson in the last exchange(s) with Kevin. What he did was to selectively quote-mine old analyses (ignoring the last quarter-century of work), cherry-pick the data (East Antarctic while ignoring Antarctica as a whole), and misrepresent implications (wrongly equating increased snowfall with mass balance, ignoring greatly increased melt and calving). And concluding with a Bizzaro-world interpretation exactly opposite that of the IPCC.
This is in fact a fairly common denier tactic - select tiny bits of the science out of context and miscast them in contradiction to the whole. I strongly suggest reading the original sources (which isn't difficult if you start with abstracts and work your way up as you can or as desired), and check the quotes and sources.
IMO denial is broadcast with selective reading and presentation, some of which (see anything from Lord Monckton) is simply false. Armor yourself by checking the assertions from all participants.
There was some refreshing language from a climate scientist on this a few days ago.As I wrote earlier, Cook is an advocate and as such, corrupt as a scientist, and proper debate should be sourced elsewhere.
I believe advocacy by climate scientists has damaged trust in the science. We risk our credibility, our reputation for objectivity, if we are not absolutely neutral. At the very least, it leaves us open to criticism. I find much climate scepticism is driven by a belief that environmental activism has influenced how scientists gather and interpret evidence. So I've found my hardline approach successful in taking the politics and therefore – pun intended – the heat out of climate science discussions.
They call me an "honest broker", asking for "more Dr Edwards and fewer zealous advocates". Crucially, they say this even though my scientific views are absolutely mainstream.
But it's not just about improving trust. In this highly politicised arena, climate scientists have a moral obligation to strive for impartiality. We have a platform we must not abuse. For a start, we rarely have the necessary expertise. I absolutely disagree with Gavin that we likely know far more about the issues involved in making policy choices than [our] audience.
..........
We must be vigilant against what Roger Pielke Jr in The Honest Broker calls "stealth issue advocacy": claiming we are talking about science when really we are advocating policy. This is clearly expressed by Robert T Lackey:
"Often I hear or read in scientific discourse words such as degradation, improvement, good, and poor. Such value-laden words should not be used to convey scientific information because they imply a preferred … state [or] class of policy options ... The appropriate science words are, for example, change, increase, or decrease." (Science, Scientists and Policy Advocacy)
As I wrote earlier, Cook is an advocate and as such, corrupt as a scientist, and proper debate should be sourced elsewhere.
However let me be the first to admit, the chart doesn't prove or disprove anything, merely a point of interest and was posted as such.... seeing that arctic sea ice is often such a point of focus.
Basilio,
Unskeptical Science is still an advocacy site, no matter which advocate or group of advocates write there. Ergo, a biased view is presented. Hence it is corrupt, from a scientific perspective.
One should seek out honest brokers for more balanced discussion.
It's because you are a "believer" basilio.
Like Skeptical Science and the Graniad?No it's because I can read and evaluate evidence from the widest range of credible sources,
Its the same belief which recognizes gravity, x rays, neutron stars, the existence of the ice ages and a million other scientific understandings.
No, actually, you're not.It's not absolute. I'm open to credible alternatives that can offer enough evidence to re evaluate my current beliefs.
If there is a body of evidence around that can substantially challenge the view that CO2 and other greenhouse gases are warming the atmosphere and that if their growth is left unchecked they will take us into a far more hostile environment I'm all ears.
Fascinating how language can be twisted. George would be proud of you Wayne.
Only on this forum could accepting the tested evidence and observations of 10,000 plus scientists on a particular field be construed as "faith". Last time I looked faith was belief in something with little or no substantiating evidence.
I notice Wayne how reluctant you are to respond to any discussion of the myriad scientific papers around the causes and effects of climate change/global warming. Clearly, according to you, if they have been quoted in Skeptical Science they can only be articles of faith rather than valid science.
... and sycophantic acolytes such as yourself, swallow it uncritically, holus bolus, ipso facto, substituting faith for enquiry ...
Sycophancy is obsequious flattery. Botticelli's illustration of Dante's Inferno shows
insincere flatterers grovelling in excrement in the second pit of the eighth circle ...
