Dear SPQR,
Nice meal and rather pleasant red has me in a decidedly convivial mood so I thought I would take the time to answer your question without you having to do the small amount of work I set you. Am I not merciful. You asked “How are we to believe your predictions & models when your highest authorities/representatives cannot get it right?” I thought I would answer by looking at the 'father' of the Global Warming scientists James Hansen who heads the NASA Goddard Institute for Space Studies, a position he has held since 1981. It was in that year Hansen and others published the paper Climate Impact of Increasing Atmospheric Carbon Dioxide. It should be remembered that global warming had not really revealed itself yet in the temperature record and the models he and the team used were quite rudimentary in comparison to what is available today. He wrote back then; "The global temperature rose by 0.2°C between the middle 1960's and 1980, yielding a warming of 0.4°C in the past century. This temperature increase is consistent with the calculated greenhouse effect due to measured increases of atmospheric carbon dioxide. Variations of volcanic aerosols and possibly solar luminosity appear to be primary causes of observed fluctuations about the mean trend of increasing temperature. It is shown that the anthropogenic carbon dioxide warming should emerge from the noise level of natural climate variability by the end of the century, and there is a high probability of warming in the 1980's."

He then modelled a projected global temperature change at a high growth scenario at 4% per year and a low growth one at 2%. The actual growth from 1980 to 2000 was 3% per year. Here are the curves along with the actual temperature rises. Remember the actual growth rate of 3% lies in between the red and blue lines. http://www.skepticalscience.com/pics/Hansen81ModelvsObs.jpg Damn he was and is good! He also gave some predictions; "Potential effects on climate in the 21st century include the creation of drought-prone regions in North America and central Asia as part of a shifting of climatic zones, erosion of the West Antarctic ice sheet with a consequent worldwide rise in sea level, and opening of the fabled Northwest Passage." We now know we can check the boxes on all four. Remember these predictions were made over 30 years ago. His efforts might not match those of Darwin who produced his work without the benefit of any knowledge about DNA but they are spectacular none the less. For Hansen's predictions to have been so accurate with the tools he had at his disposal has been quite remarkable. He is deserving of our respect and admiration not the petty sniping and the labels of 'conman' bandied about by the likes of Hasbeen and yourself, and other discredited fellow travellers on this thread. So to answer your question you should believe because they did in fact get it right! Is this where I apologise for bringing some science back into the thread? Are we really that dumb that after all that we want to see every predicted consequence of AGW in front of our very eyes before we agree there is a problem? Are we really that stupid as a species? It appears some of us may well be. Posted by csteele, Monday, 14 May 2012 10:29:10 PM

Dear Hasbeen,
An 8 word response? Looks like you’re done. And runner’s done a runner, Jayb is doing time for cooking the books, individual’s gotten so rattled he has been striking out at his own side while SPQR is striking a blow for total irrelevancy and was last seen going though some of my posts from 5 years ago. Could it be my work here is done? Pity. Spoil sports. Any chance of a few pithy retorts as you exit, just for old times sake? I’m missing you guys already, we might even meet on another thread about AGW, perhaps we might all have grown up a little too. Fingers crossed. Posted by csteele, Monday, 14 May 2012 11:48:00 PM

@CSteele,
You still haven’t answered my question. You tried to side step it. It wasn’t about James Hansen—it was about Tim Flannery. And here are my citations/charges (TAKE YOUR PICK!) The first citation is from Stewart Franks, Associate Professor School Of Engineering University Of Newcastle. He doesn’t just out Tim Flannery, he also outs (those other prominent climate change spruikers ) David Karoly and the CSIRO. " Tim Flannery, now Australia’s Chief Climate Commissioner, declared rather bizarrely in 2007 that hotter soils meant that “even the rain that falls isn’t actually going to fill our dams and river systems. Fast forward to 2012 and we see widespread drenching rains, flooded towns and cities, and dams full to the brim and overtopping. Indeed, the rainfall that we had last year not only filled Brisbane City’s Wivenhoe Dam water supply storage, but also all of its flood mitigation capacity. The resultant releases of water required to prevent a truly catastrophic dam failure contributed to the inundation of large parts of metropolitan Brisbane... However, it turns out that it is not just Flannery that has been making incorrect statements – many supposed experts including prominent commentators from the Bureau of Meteorology and the CSIRO have been making equally incorrect statements... http://theconversation.edu.au/climate-and-floods-flannery-is-no-expert-but-neither-are-the-experts-5709 “We're already seeing the initial impacts and they include a decline in the winter rainfall zone across southern Australia, which is clearly an impact of climate change…even the rain that falls isn't actually going to fill our dams and our river systems, and that's a real worry for the people in the bush. If that trend continues then I think we're going to have serious problems, particularly for irrigation.” http://www.abc.net.au/landline/content/2006/s1844398.htm “Every NSW town visited by Professor Tim Flannery or his Climate Commission colleagues for community forums where residents were told they were in a "drying trend" has been deluged by rain up to three times the annual average… http://www.dailytelegraph.com.au/news/sydney-news/its-a-case-of-tim-foolery-as-flannerys-predictions-of-dry-dams-go-unfulfilled/story-e6freuzi-1226297567261 Posted by SPQR, Tuesday, 15 May 2012 12:05:58 AM

But, wasn't that some Psycho, er, sorry, Psychic. Well much the same as some of these Climate Scientists & their Green lefty, PC sheep.
