Ice core samples have ancient air trapped in them, and from that we can tell that at no point in the last 800,000 years has the level of carbon dioxide in the atmosphere been over 3/100 of 1 percent. That is, until the industrial revolution, and it's since continued to rise rapidly. The amount is now 40% higher than it was at the beginning of the industrial revolution. Do you honestly believe that's just a wacky coincidence?
Perhaps you think it's volcanic carbon dioxide, except the 500 million tons (that's extremely generous, I've seen estimates as low as 200m/yr) of volcanic carbon dioxide that are expelled each year isn't even 2% of the 30 billion tons that man expels each and every year from burning fossil fuels. Not to mention the effects that deforestation have on CO2 levels. Volcanic carbon dioxide is heavier than the CO2 from fossil fuels, so when studied at the molecular level scientists can determine where the increase in carbon dioxide comes from... so when you say the link to man made CO2 is weak you simply don't know what you're talking about. And by the way, the current climate change and rate of global warming correlates with the known amount of carbon dioxide that man expels each year. Probably just another wacky coincidence.
The case is pretty cut and dry for anyone who doesn't have an agenda. If you want to point to an article that says someone (Al Gore for ex) may profit off of alternative energy as your reason for thinking it's just some elaborate hoax, then whatever. Your conspiracy theories have no effect on my life or reality, so I'll leave you to it. It's not like anyone profits off of fossil fuels, right? I'm sure no one has an agenda on that side right?...
My conspiracy theory is you don't actually believe what you're typing, you're just playing dumb to increase interest in the OT forum. Good luck with that.
