We could start with this from here And there is a review of evidence here
"Scientists have been debating this question for about 20 years now. As one of the world's leading climate scientists, Stefan Rahmstorf of Potsdam Institute for Climate Impact Research, puts it, the current scientific view of global warming is: "based on decades of research and thousands of studies. The extraordinary consensus reached is seen in the statements of many international and national professional bodies which have extensively and critically assessed the scientific evidence." Prof. Rahmstorf has compiled a very useful climate change fact sheet (PDF format) summarizing the evidence in a couple of pages. The BBC has produced a handy website on global warming with a section called Evidence, which contains charts showing climate trends over the last few years. Browse those charts and you will see that Earth's temperature has increased systematically over the last century, sea levels have rised significantly, and carbon dioxide emissions from burning fossil fuels have increased almost exponentially. Most climate scientists believe these things are connected: they consider that the burning fuels cause the carbon dioxide emissions, which make the temperature increase, which causes the sea levels to rise. (If you want to see lots more charts, take a look at Global Warming Art.) Since records of the weather date back only a hundred years or so, how can scientists confidently make claims that the climate has been changing over a much longer period? In turns out that Earth keeps a natural record of its own climate in many surprising ways. For example, as ice has formed year upon year at the poles, old ice has been buried underneath with bubbles of air trapped inside it. The bubbles act as a record of what the air was like on Earth when the ice formed—and thus what the climate was like in years gone by. Using drills, scientists can extract ice cores (long thin pipes full of ice), study the air bubbles at different depths, and calculate how much carbon dioxide they contain. If they figure out how old the ice is, they can use an ice core as a kind of graph of how carbon dioxide has changed over time. Scientists can also study changes in the climate using ocean sediments, samples of buried pollen, and other, once-living matter. Research like this can tell us what the climate was like hundreds of thousands of years ago. Although most scientists believe in global warming, it's important to note that a minority do not. Some agree that Earth is warming but not that fossil-fuel burning and carbon dioxide emissions are responsible. The "climate-change skeptics" argue that increases in Earth's temperature are either not happening at all or may be caused by other things, including natural variations in the climate that have been happening for millennia. In recent years, however, fewer and fewer scientists have dissented from the widely held position that global warming and climate change are really happening. People could still be wrong about global warming—but that's becoming increasingly unlikely."[URL=Is climate change really happening?

Overall, I dont see anything wrong with the video(and it appears that you cant find particular fault in any of the science presented either), what parts to do you want more explicit information on? If you need info on the actual wavelength of the em spectrum that causes the asymmetric resonance of the co2 molecule or want detailed calculations involving boltzmann's law on emissitivity and emission rates from the earth's different surfaces, then there are more advanced readings that could be recommended. But Im guessing that is not your aim at all? |

Thanks for those 'informed' one-sided websites, here is one you can use to help balance the argument...

I believe we are responsible for environmental destruction, the poisoning of waterways and the air. I do not believe introducing a tax which does not have the capacity to reduce human CO2 output will make any difference to the global climate. We live in a country which accounts for 3% of total CO2 output? Why has the PM decided we should put out neck out? I'm very suspicious indeed.

Carbon tax wont achieve anything except increase the cost of any locally made product. Farmers and manufacturers will be hit with increased costs (power/energy costs to transport costs) these will be passed on to retailers (who have their own increased costs) and all this in turn will be passed on to the consumers (which is all of us) Add to the the costs of administrating this tax and basically you might as well send all our farming and manufacturing off shore. It doesnt matter how "green" you are, you could have a 3.7Kw solar setup, collect your own rainwater and have a push bike as your only means of transport. You will still pay for this carbon tax. If you really think carbon tax will help save the enviroment, did the alcopop tax stop teens from binge drinking? This is just another money grab, it has nothing to do with the enviroment (the power companies, who are polluting will be compensated so they will not be out of pocket, its only the consumer who will be out of pocket) If the government trully wants to improve the enviroment they would not be axing the solar rebate scheme or RECS. Oh and another way to reduce pollution, reduce congestion and increase speed limits.

can some one tell me how it is going to create these jobs.as it is going to cost many more thousands.

I think we might have taxed the wrong nation / continent.
20 million Australians consumption versus 6 billion............and we're the only one with a tax? Ok...........

34,000 jobs?
So lets hypothetically turn off the nasty Liddell power station. Not wanting to cause massive black-outs, we will replace Liddel with a solar power station, we could even use the "best of bread" Olmedilla Photovoltaic Park power station in Spain as a guide. There is one small problem. Lidell produces 2,000 MW 7x24x365 Olmedilla produces a nominal 60 MW Anyone see the problem yet? We'd have to build an equivalent of 32 Olmedilla's to replace just Lidell! Maybe that where the 34,000 jobs come from? In fact, the worlds 49 largest solar power generation plants (plants larger than 20MW), their combined generation totals 1654 MW - reference wiki. One moderately sized coal/gas or nuclear power station exceeds their entire output. Wind generation has similar "poor" power generation characteristics. Maybe I've got my maths wrong, maybe I'm not seeing the big picture, I'll invite anyone to help me understand how the heck "green" energy via this tax is going to keep the lights on? |

they cant it is just a tax to dig themselves out of a hole like the mining tax was going to be.
They have no money and need to find new ways to getit. Ian

Unless this is applied GLOBALLY, big business is simply going to move manufacturing off shore to countries which don't have a tax... and I'm looking in the direction of China/India etc whose environmental reputations are not as good.
My feeling is that Australia's interests would be better served with a carrot rather than a stick: Greater incentives for 'green' research, development and investment. Technologies such as Geothermal, solar, wind and Nuclear can all play a role - but as yet, they all need to mature further to be real competitors for fossil fuels. IF Australia could develop technologies that are competitive, then we have the potential to actually earn from it - IF we resist the temptation to sell off the rights for a bargain basement price as we have in the past... On the subject at hand: There must be a much greater investment in research to alternative fuels. Making a switch to electric or fuels such as Hydrogen will take decades... there needs to be an alternative that can be used in current vehicles. Biofuels will play a role, but the crop-based ones then become a competitor for food crops. One that is interesting is to use algae as a source. Last edited by AndrewR_AUII; 28-02-2011 at 04:09 PM. |

That is part of the problem that the government faces, people think there is actually divide on the science here, the denialist campaign is working well indeed! There is no “other side” that is presenting science that challenges the current agw prognosis. What we have is a campaign of misinformation and deceit by some very persistent and well funded organisations. The approach has been summed up recently in: http://judithcurry.com/2011/02/08/li...loses-comment/ It is also clear to me that the so-called ‘skeptics’ are allowed to make up whatever they want at will without consequence, and create a large but ill-thought out laundry list, and that we must play this game or else we’re being ‘dogmatic.’ If a climate scientist make one mistake, or a date gets screwed up in the middle of a 1000 page document about glaciers, it will receive international attention. However, if ‘skeptics’ toss out 8 conspiracy theories, 10 logical fallacies, and 17 arguments with ZERO thought put into them, then it is a good thing that we get to hear all sides. Then, when one item on the bucket list is knocked down, they can just jump to the next item. In the meantime, they are just as valid as everyone else’s idea, since the criteria for acceptance is 101% certaintly in everything. Perhaps read up on Anthony Watts and his website: http://www.planetthoughts.org/?pg=vi...Video&qid=2968 http://www.youtube.com/watch?v=B7OdCOsMgCw Whether its spam emails about volcanoes or Anthony Watts spreading rubbish the tactics follow the pattern outlined above by Judith Curry. No doubt some or you will continue to be conned and present them just as the wattsupwiththat link was presented by cheap and hope that it wont get knocked down......go ahead I couldn’t be bothered! |

So provided we split the world into tiny countries where no country emits more than a couple of percent then no-one will need to do anything? We are only 0.35% of the population of the planet but produce 3% of the co2(making us the highest per capita emitters on earth), does that sit well with you? Most denialists look to excuse themselves from not having to do anything by pointing to the apparent extravagance carbon emissions of the pollies. Dont you think other countries might take the same attitude with us if we also take the do as I say approach and not as I do. Really this thread/discussion should be about how much we pay for carbon tax, in my view the figures already mentioned are very moderate indeed. |

I'm with Sudszy on this. You can make all the claims you like. The reality is that the science is well accepted. Has been worked on by numerous researchers around the world over many decades. Not only is it well accepted by the science community, it is well accepted by the international community and their governments. The only area that hasn't been nutted out is who will have the long term strategic insight to take action.

Is it such a bad thing to try and limit each persons carbon emissions to a level? If we each produce more carbon emissions than others do, regardless of country boundaries, it could be argued that we have a moral imperative to show we are willing to change, even though our national emissions are lower than other counties.
