Climate threat to polar bears: despite facts, doubters remain : Comments

Ed Struzik has a distorted view of facts. For a start, he fails to acknowledge the fact that the UN set up the IPCC to prove the greenhouse theory, but after 20 years of searching it has failed to find any irrefutable scientific evidence that global warming is man-made. Consequently, it is erroneous to claim that increasing concentrations of CO2 are causing Arctic ice to melt, and polar bears to diminish in size and numbers. In any case, there have been much higher CO2 concentrations in the past, and polar bears survived. There is simply no scientific or economic justification to impose CO2 taxes, so as to penalize existing efficient energy sources and thereby heavily subsidise unreliable renewable energy sources, particularly those of the when-the-wind-blows and when-the sun-shines variety.

Q&A,
You are just an idiot and you don't know what you are talking about Posted by Leigh, Thursday, 23 July 2009 2:36:28 PM

Leigh,
You are obviously not aware of who popularised the term "climate change", why or when it was done. http://www.guardian.co.uk/environment/2003/mar/04/usnews.climatechange 6 years old already! epilogue: Frank Luntz now believes AGW is a serious problem.

Teasing the skeptics again Q&A? Perhaps you could explain some of the contradictions rather that talking down to us mere mortals or sniping from academia.
Global temperatures have dropped since 1997, and yes they “could” be masked by other climatic complexities. I have however seen temperature data that does show a very slight upward tend of less than .3 of a degree over an even longer period. So whatever is happening to ice caps, polar bears and extreme weather events is happening during a cooling period. Perhaps Ed Struzik or you could explain this anomaly? The science is not settled and there is no consensus, except to say that the many scientists that support AGW have consensus and the scientists that don’t agree with AGW have consensus. I accept that atmospheric carbon concentrations have increased dramatically; I also accept that this is “potentially” a problem. I say potentially because there is no direct evidence of GW at the present time. The only “evidence” is prediction based from data modeling. The problems with data modeling are numerous; the most significant are that modeling works on “garbage in- garbage out” and “interpretation”, its two greatest weaknesses. Give us something to address the anomalies. Posted by spindoc, Thursday, 23 July 2009 4:03:51 PM

What a bummer.
You write a book about Global Warming, entitled The Big Thaw, & not only does global warming stop, but the bl@@dy ice all comes back, as well. The poor bloke really does have a dilemma. I guess the only course of action is to pretend it isn't happening, & do advertising/promotional pieces, like this bit of fantasy. You have to hope you can git rid of enough books to make a bit of proffit, before the deep freeze really sets in. Posted by Hasbeen, Thursday, 23 July 2009 5:17:52 PM

<< When the Arctic heats up the Antarctic cools and vice versa.>>
Yep, some say when it's summer in the NH, it's winter in the SH - and vice versa.
<< To think that increased temperature leads to melting ice everywhere is a simplistic child's view of science. >>
Hmmm;
Put energy into a system, it heats up - if there is water around it evaporates (or melts), condenses out somewhere (as rain or snow). Middle Antarctica growing, Arctic ice shrinking.
Ergo;
The more energy in, the more 'extreme weather' events out - simple physics. (A little more complicated Atman, but you get the drift).
