1. Yes, but it's 20 times pre-industrial carbon dioxide (around 6000 ppm, but it could have been as low as 2000 ppm) and life flourished in the ocean, not on the land. During the Cambrian, there was a supercontinent called Gondwanaland, which was centred around the South Pole. Now tell me why this is relevant.
The first mammals appeared about 225 million years ago, since then we have had CO2 levels that have come close to 3000ppm, and mammals thrived.
Quote:Of course this is published data. Where do you think the research came from? Andrew Bolt?
Andrew Bolt, God bless his soul is only quoting from scientists cause he isn't one............!!!!!!
Quote:Explain what you mean by hand-picked proxy data?
Well I cant be bothered finding it now, but I showed you a paper not long ago for CO2 and temperature and you rejected it because it stated that CO2 according to the proxy data follows temperature plus it was from the desert of USA, the proxies where from some type of tree.
If it had of supported your case you would have been all over it like a rash.....!!!
Quote:There is no credible dispute.
WTF are your talking about this is where you guys come unstuck.
No one really knows how much of the increase is due to manmade CO2 emissions, since we are coming out of a mini ice age for the last 400 odds years or so and our sun was very active in the last 30 odd years.
Now our sun is going into an in active period for a few decades as i'm lead to believe, and viola CO2 keeps rising while temperatures have remained flat and might even head south.
So how much is natural and how much is manmade is any bodies guess.
Show me with 100% confidence how they can determine all the CO2 rise is solely due to manmade CO2 emissions....???
Quote:To fix the problem, we need to stop burning fossil fuels and substitute renewable energy.
Does the IPCC advocate a Carbon Trading system? I doubt it. I'll check it out and let you know. Right. If it's going to be anywhere, it would be in the summary for policy makers.
http://www.climatechange2013.org/images/uploads/WGIAR5-SPM_Approved27Sep2013.pdfHave a look yourself, but I can't find anything in that document that even mentions Emissions Trading or Carbon Tax.
Are you for real, I think the IPCC invented the concept of carbon pricing.
Playing dumb now muso, try under, Mitigation of Climate Change
