Scientists, politicians and tree hugging hippies claiming conclusively that man has caused global warming makes me angry. Carbon Credits make me even more angry.
we were discussing this a few days ago..

good thread. Good to see that people are taking "evidence" with a healthy dose of skepticism.
You know I'm sick of the skeptics. From now on the skeptics actually have to present evidence for their argument.:bball:
That'll shut them up. They don't have any.
^^ Conclusive proof??? Without on site measurements as the event happened?????
Have a read of some of the research that looks at historical geological changes. The climate stuff involved in that is actually a lot more "conclusive" than people think. Start with the review papers and books. Granted they are tieing a lot of stuff together but the cycles that occur have pretty likely drivers as far as I can remember.
Well you have two options.What I am saying is that no one can conclusively prove that man made CO2 is the cause of global warming.
I agree that there is going to be bad decisions made by government. But that isn't because of a lack of information, it is because of a overpreponderance to believe lobby groups.The other part of this, the sad side is all the public policies that are made with this information can do a lot more harm than good. The US pumping so much cash into Ethanol, and screwing over the corn economy. Hybrids getting a big push (the batteries in these things are one of the worst products ever developed when it comes to environmentally disposing of them).
Well you have two options.
1) Wait 50-100yrs and take measurements all that time. Over this time you should be able to prove and measure exactly what is happening. On the downside life as we know it will change, and not for the better.
2) Do something now and maybe avert major changes in the climate such that we may never conclusively measure CC.
As an example of something that we take for granted, have no real understanding of, yet is happening anyway - quantum mechanics. Want proof, pick up your phone. Want to measure it..... can't be done. Want to understand it...... good luck. Does it mean that we should wait awhile before diving into having phones (and other quantum mechanics devices), you tell me.
I agree that there is going to be bad decisions made by government. But that isn't because of a lack of information, it is because of a overpreponderance to believe lobby groups.
Ethanol isn't bad, but the way it is being subsidised and the methods of manufacture are plain stupid. People knew this before they started, they just had $$ in their eyes. Oh and US corn is one of the most overinflated agricultural products in the world. Thankyou lobby groups for creating yet another market for a product no-one actually wants.
Hybrids aren't a bad idea, but they have limited application in road transport (which should be moved to more public means). I agree the batteries aren't good. The problem with hybrids is that they should have been inovating and developing the technology for decades. Instead we now get a flurry of excitement about them and roll outs that should have been further along in development. These are the leather sandle when we should have the cushioned running shoe.
Yes this is true. But the ability to sustain human life as we know it under CC would be nigh on impossible. Take for example grain production. I think most cereal plants require <550ppm (I can't remember the exacts of this figure) of atmospheric CO2 to grow without inhibition. So by the end of this century one of the largest staples in the world diet will no longer be able to grow!!!!!My point is, that life on earth has always been changing. It has never remained static. Here is the question, do we wish to preserve the environment as it is now or do we wish to let nature take its course? As mentioned in my other posts, at no time in earth's history has it been static. Things as simple as north and south aren't even consistently in the same place.
Fair enough, and a valid point. I don't particularly like the idea of climate change, I don't like that our urban centers are clogged with smog. That for me is reason enough to watch our efforts. I just have a problem with the scientific community present things to the public as conclusive fact when they are not.
I also agree that there are many things we do not understand. Hell, we don't even understand the nature of gravity yet. Heisenberg's uncertainty principle is a lovely piece of science, as is the Schrodinger equation, as is the theory of relativity. Does the fact that we do not fully know what the consequences will be mean we shouldn't experiment with the stuff? Hell no, if that were the case we would still be in the stone age. Experimenting with man made emissions and environmental conditions is certainly a valid experiment. But that's what they are.
There are other ways of making ethanol and biodiesel, other sources, that are really quite good. Unfortuneately the lobbyists have pushed in all sorts of junk. My friend is doing research on canola as a biofuel, he did some back of the envelope calcs when he started and realised it was stupid. But our dept has been investigating a biofuel from tree pods that yields 30x that of canola.Ethanol (in present times) as a fuel is bad. It takes more energy to make than it gives off. This net negative energy balance makes it completely impractical. Until we have more efficient and advanced methods of making it we are just screwing ourselves. The energy to make it has to come from somewhere, and if its the US then that energy likely comes from burning fossil fuels. Exploring alternate fuels is an excellent proposition and have great hopes for it (as an automotive engineer).
I've enjoyed this chat too. I'm glad your not a denier. I really get sick of having to defend science. Just the other day someone said that CC hadn't impacted on yield in our area of the world (West Australia). Well the reality is that 30yrs x 5% = 200-300 kg/ha of yield decrease in that time period. We would barely notice that as it has only been the last 10yrs that our equipment would be accurate enough to measure that change. Plus yield variability is of the order of 500kg/ha in any given field, let alone farm or district or state.Anyways, this has been a great discussion Tim. You have made some strong arguments. Just don't mistake me for one of the head in sand deniers. I am just not convinced of the source of global warming yet. There have been some interesting studies done on the effect of atmospheric water vapor and global warming done recently, have you read any of that? Those are very good reads. Can you recommend any favorite journals or papers of yours related to carbon emissions? I have read a lot of the north american literature, but not much from elsewhere.
I want a solar panel on my house, a electric car, and possibly, everything in house run by renewable energy, im serious. me and my pep pep , aren't tree hugging hippies, but we love saving money, and seeing our banks increase with $$$, rather than go V = downhill
Yeh Solar panels take several years to pay for themselves (dependant on sunshine hours).
Electric cars are not as good as fuel efficient cars in terms of cost and pollution (well, from what I've read in lay media, no research to back this one up).
I had a buddy talking to me about the carbon credits saying how he thinks its gonna be huge because from my understanding, people will be trading them just like stocks, bonds, and commodities?
