There is considerable confidence that climate models provide credible quantitative estimates of future climate change, particularly at continental scales and above. This confidence comes from the foundation of the models in accepted physical principles and from their ability to reproduce observed features of current climate and past climate changes. Confidence in model estimates is higher for some climate variables (e.g., temperature) than for others (e.g., precipitation).
Over several decades of development, models have consistently provided a robust and unambiguous picture of significant climate warming in response to increasing greenhouse gases.
... Models are routinely and extensively assessed by comparing their simulations with observations of the atmosphere, ocean, cryosphere and land surface. Unprecedented levels of evaluation have taken place over the last decade in the form of organised multi-model ‘intercomparisons’. Models show significant and increasing skill in representing many important mean climate features, such as the large-scale distributions of atmospheric temperature, precipitation, radiation and wind, and of oceanic temperatures, currents and sea ice cover. etc
Frequently Asked Question 5.1
Is Sea Level Rising?
Yes, there is strong evidence that global sea level gradually rose in the 20th century and is currently rising at an increased rate, after a period of little change between AD 0 and AD 1900. Sea level is projected to rise at an even greater rate in this century. The two major causes of global sea level rise are thermal expansion of the oceans (water expands as it warms) and the loss of land-based ice due to increased melting.
Global sea level rose by about 120 m during the several millennia that followed the end of the last ice age (approximately 21,000 years ago), and stabilised between 3,000 and 2,000 years ago. Sea level indicators suggest that global sea level did not change significantly from then until the late 19th century. The instrumental record of modern sea level change shows evidence for onset of sea level rise during the 19th century. Estimates for the 20th century show that global average sea level rose at a rate of about 1.7 mm /yr.
Satellite observations available since the early 1990s provide more accurate sea level data with nearly global coverage. This decade-long satellite altimetry data set shows that since 1993, sea level has been rising at a rate of around 3 mm yr−1, significantly higher than the average during the previous half century. Coastal tide gauge measurements confirm this observation, and indicate that similar rates have occurred in some earlier decades.
There is so much publication bias out there that I wouldn't have the time to sift through it all.
Reason is the first filter I use.
I then discount all normal curves and graphs. They are crap, not enough info.
Mandelbrot and Taleb I listen to.
This guy in the UK Daily Telegraph is as believable as anything else I've seen.
My lighting up a Cohiba in my Monaro is less danger to the earth than these jokers with their particle colliders in Switzerland.

Frequently Asked Question 8.1
How Reliable Are the Models Used to Make Projections
of Future Climate Change?
I reckon some of the ocean rise is due to all the additional inbound cosmic debris, cosmic dust, meteor showers etc - if this all gets washed into the sea it's going to cause it to rise.
Also the additional Sun Spot activity that's been going on is like we've been placed in the path of a microwave oven with the door open. All that sub atomic radiation and photons pouring in are going to heat up our oceans like a tin of soup.

And that's after again debunking the nonsense that comes from Monckton.
Anything out of the UN is suspect for a start,
ok - let's look at 1m rise :-1.1 mm per year? That means that if this were to continue for 1000 years, sea levels would be 1.1 meters higher. Doesn’t sound very catastrophic, does it?

I've never said that. I've said that it probably is not anthropogenic. But the warming trend may be reversing.ok wayne
the arctic ice isn't melting (as you've posted many times)
Correctthe polar bears aren't in distress ( ditto)
They have been rising since the little ice age but show no acceleration due to A. factorsthe seas aren't rising to any significant degree (ditto)
el nino/el ninanor are they warming ( ditto)
Absolutelythe IPCC are a mob of lying bastards,
Back to your disgusting misrepresentation of my views again. You are a lying **** over this. Time to stop that and grow up.and the representatives of Exxon etc who proclaim "all's well folks" - "don't bother to invent new technologies - you're happy with petrol guzzlers right ?" - are all honourable men ..
Yesand btw, David Suzuki is obviously an idiot , because he wants politicians who ignore global warming to be held legally responsible.
well the good news wayne is that what I believe doesn't matter
and the way things are trending
what you believe matters even less.
And your point is?Please read this article http://newsbusters.org/node/13698

"The IPCC "science" is under attack from many quarters for their use of suspect modelling and ignoring observation. However attacks on the validity of their findings are largely unreported in the media.
The alarmists feel they are ahead while they have the hearts and minds of liberal politicians and the mainly liberal media, especially in America.
Likewise the alarmists on this thread are trying to convert nonbelievers by a combination of sheer volume and browbeating.
They have done this for 45 pages. Have they made any conversions? What is their political agenda?"
Maybe those suggestions should be the topic of another thread but this thread appears to be a in a bit of a stalemate.
