“CO2 levels through earths history.
Look and the levels of CO2 between the Triassic,Jurassic and Cretaceous period.
You cant deny the bio diversity during all these periods. These times were one of the most fertile times in earths history and the CO2 levels were close to 3,000ppm compared to our lowly 400ppm today. http://www.skepticalscience.com/co2-higher-in-past.htm”
“Nice try, but this is not cool that your trying to spread misinformation to suit your belief's. You say debate on CO2 levels? Really? have you ever heard of Ice core measurements? Yes, there was The Great Dying 250MYA, but life recovered after that with high levels of CO2 in the atmosphere still. at the 240MYA mark life had recovered, and the bio diversity had recovered all the way until 65MYA with high CO2 around the 2000ppm mark.”

“Really? You might want to read articles before you reference them. Here is a juicy quote: "As the Ordovician was so long ago, there are huge uncertainties for that time period (according to the model, CO2 was between an incredible 2400 and 9000 ppmv.) Crucially, GEOCARB has a 10 million year timestep, leading Berner to explicitly advise against using his model to estimate Late Ordovician CO2 levels due its inability to account for short-term CO2 fluctuations. He noted that "exact values of CO2... should not be taken literally."
You'll note that they are saying that they disagree with GEOCARB's figures. Debate: (n) A discussion involving opposing viewpoints.
Personally, I think it is not cool that you do not comprehend the meaning of the word "debate."”
“The earth was also the most fertile during the highest CO2 levels...Today the CO2 averages about 400ppm, 200MYA the levels were as high as 2000ppm, and our planet was thriving with life in the seas and an land.”
“I'm not sure where you got your facts from, but there is a bit of a debate on CO2 levels in prehistoric times. The other fact you're conveniently leaving out of the picture is that the greatest level of CO2 concentrations around that time are generally considered to have peaked around the 254 million mark. Coincidentally enough, that was during the Permian-Triassic extinction event, known by the cute moniker of "The Great Dying." During this period an estimated 96% of all marine species and 70% of all land invertebrate were wiped out.”
“I'm not for big fan of oil my self but people fail to realize if we stopped all production of oil, we would be thrown back in to the dark ages real fast. Unfortunately green energy has not even close to replacing oil yet, Its kind of hard to beat an energy source that had billions of years to acclimate the suns energy. they fail to realize how dependent on oil they really are. people don't want to drill on our land, yet we need to get the oil from somewhere, which usually means sending money over seas to people that hate us and that becomes a bigger carbon footprint since having to ship the oil here. Also other countries have a far more relaxed environmental regulation's on extracting oil that deepens the environmental footprint over all (As long as its not in your back yard, right?). You just cant have it both ways in this imperfect world.”
“"who shut down the government for 24 billion dollars?" Both parties really did and I hold BOTH parties responsible. Are you one of robotic clones that turn your head the other way when your party is at fault? I guess Its ok for your party to do something wrong as long as their Democrat? Right?”
“Are you serious? Ignorance is bliss for you I'm sure. You just keep believing the Democrats are on you side, are not part of the problem, and care for you so much.”

“And that flippin' loon Rand Paul cares? You are so far beyond clueless you'll never find your way back. Your credibility is less than zero. I hope you realize that. But I doubt you are bright enough to see anything outside your little echo chamber.”
“Just like I could care less what you think, you're obviously not smart enough to back away from BOTH parties.”

“BS. The major problems in this country are the blame of the GOPTBers and you know it. But you aren't mature enough or honest enough to admit it. BTW - My Jr. Senator is the only (I) in the chamber. You are the one lacking in smarts, buddy boy.”
