« Recent 'Antarctica warming' study badly flawed | Main | Air Con Number One again »

Comments

Iwi's hart.

1. You quote your own magazine article and your own book constantly. Lame. Can you cite anyone else's work Ian?

2. Some nice quote mining there. Although your syncophants who just as terrified of the "New World Order" may buy it, normal people wont.

Here is another part to that article you quoted:

Not that Greenland's ice is safe, says Alley. "If you turn the thermostat too high, it will melt," he notes. And the glaciers of the West Antarctic Ice Sheet (WAIS), some of which have already picked up speed, don't have the shallow rocky underpinnings that allow Greenland's glaciers to regain their equilibrium. "With nothing to hold on to," he says, "we think [WAIS] will run away."

And from the second article you quoted:

The team also used assessments of the world's small glacier and ice cap contributions to sea level rise calculated by a CU-Boulder team and published in Science in July 2007. That study indicated small glaciers and ice caps contribute about 60 percent of the world's ice to oceans at present, a percentage that is accelerating.

Considering all major sources of sea level rise, including Greenland, Antarctica, smaller glaciers and ice caps and the thermal expansion of water, the team's most likely estimate of roughly 3 to 6 feet by 2100 is still potentially devastating to huge areas of the world in low-lying coastal areas, said Pfeffer.

Some scientists have theorized that continuing warming trends in Greenland and Antarctica could warm the Earth by 4 degrees F over the present by 2100. The last time that happened, roughly 125,000 years ago during the last interglacial period, glacier changes raised sea level by 12 to 20 feet or more. But the time scale is poorly constrained and may have required millennia, Pfeffer said.

"In my opinion, some of the research out there calling for 20 or 30 feet of sea rise by the end of the century is not backed up by solid glaciological evidence," said Pfeffer.

Policymakers need to be able to predict sea level accurately if communities, cities and countries around the world are going to be able to plan effectively, Pfeffer said. "If we plan for 6 feet and only get 2 feet, for example, or visa versa, we could spend billions of dollars of resources solving the wrong problems."

Fairly obvious you haven't actually read Air Con, iwis.

It has more than 400 referenced footnotes and cites.

Wishart devotes some considerable space to Arctic and Antarctica "melt", and from what I can see has quoted thoroughly in context.

The rate of sea level rise has decreased, and the "thermostat" is winding down at present.

And have we managed to establish that Antarctic Peninsula and WAIS "warming" is CO2 related, rather than natural?

Didn't think so.

Iwi's hart.

Ian quotes two articles that contradict his opinion in this particular blog.

How do we know that he doesn't use quote mining tactics in his book?

Anyone can take over 400 articles out of context.

Can you give me some primary literature to assert you claims that climate change isn't happening Trent?
Thanks

Yeah good one, prove a negative.

Talk about a broken record..........

Iwi's hart.

You are either claiming that the Earth is cooling- which would need a valid, supported theory. Or that CO2, which under normal circumstances should create a greenhouse effect, isn't causing one.

So, sources?

Shane Ponting

Time to [/b] turn off the bold type.

Shane Ponting

oops this is html not bb code,

Shane Ponting

testing.......

Shane Ponting

damn subordinating code, we need to fix the templates Ian....

Ian, you say:

' Then there’s South Island truffle fancier Gareth Renowden, an “immediate past president of the NZ Truffle Association” and self-appointed ‘expert’ on human-caused climate change, '

Exactly who appointed YOU an expert on climate change Ian?

Trent

I'm unaware of any argument that climate change is not happening iwis. Can you show me where I said that?

Iwi's hart.

Trent: So you accept that long-term climate change is happening?

What mechanism do you think is causing it?

Perhaps greenhouse gases? Which cause the greenhouse effect? Of which humans have emitted a significant amount of into the atmosphere.


Or do you doubt the physical properties of carbon dioxide, the amount of CO2 emitted by humans or the data that show the recent rise in atmospheric CO2?

Trent

Again, iwis, the case is admirably made in Air Con based on the peer-reviewed papers...there is good scientific evidence that aerosols, oceanic and solar variations are having a much greater impact on climate than CO2 emissions. You really should read the book before shooting off at the mouth.

Ian explains that the behaviour of CO2 in enclosed environments (ie, laboratory tests or greenhouses) - whilst well documented, does not exactly match the behaviour of CO2 in the wild where heat can and does escape to space because Earth has no roof.

The radiative forcings are a physical property that exist inside or out, but the relative effects inside and out are different. Greenhouses don't have convective towers, holes in the roof, large bodies of ice et etc.

Air Con points out that the rise in CO2 coincides with the widespread deforestation of the late 19th cnetury as land was cleared for farms and towns, meaning that surplus CO2 both natural and human-caused couldn't be as swiftly soaked up again.

I repeat what I said yesterday, iwis...if you haven't read Air Con then you're kind of arguing straw men that don't exist.

"Some scientists have theorized"

That sums it up!

It's just theory.

Much of which doesn't stack up in the 'real world'. Playing with pretend computer models! And that's coming from other scientists!


Iwi's hart.

Trent:
I'm not going to waste my time reading BS conspiracy theories by someone who thinks that ID is a challenge to evolution. I'd rather read actual, peer reviewed scientific reports myself.

Tell me, what scientific articles does Ian cite anyway? I'll look them up myself, and see I come to the same conclusions as he does.


BTW, deforestation emits CO2- of course it is a cause of CC. Guess who causes deforestation?
People.

Oh, and your lack of understanding of chemistry/physics/climatology is showing. I suggest you read something other than Ian Wishart books.

Iwi

Buy your own copy of Ian's book, Air Con. You don't have to read it - just go to all the references at the bottom of the pages :-)

You will then have references to actual, peer reviewed scientific articles. Different ones, and likely more recent than some of the rubbish dished up to us daily elsewhere.

I've read it, and am satisfied that the general thrust of Air Con is right on the button.

It is the interpretation of Ian to the works of others that I have often questioned.

robk

Fair enough. I have not chased up all the references, but i'd expect his opponents will have a go. Book makes sense to me, even has a possible motive for all the AGW hype...
