During the late Ordovician period about 500 million years ago the earth almost completely frozen over. The CO2 was about 3,000 - 5,000 PPM, about ten times what it is now.
And the sun was 5% dimmer. Oh, snap. Your cult didn't tell you that, and you don't know it if your cult doesn't feed it to you. You just proved CO2 is a strong greenhouse gas, because there's no other way the earth could have melted out with such a dim sun.
There are many more examples but more recently during the Medieval Warming period the CO2 was about 30% lower than what it is now but the earth warmer than what it is now.
Bzzt. Big lie. The world is much warmer now than it was during the MWP. Hate to break it to you, but essentally all of your "facts" are cult myths. It's a pity you always believed what you were told without questioning it, and never even considered fact-checking.
There is no proof that CO2 causes global warming
Of course there is. Stratospheric cooling, increase in backradiation, decrease in outgoing longwave in the GHG bands. There are no natural explanations for such things. They are smoking guns for greenhouse-gas caused global warming.
And if you don't know what those terms mean, you shouldn't be bothering the grownups.
and there is less proof that the man made portion of that cause global warming.
Absolutely wrong, as isotope ratios show the human origin of the CO2. Your perfect record of getting it wrong remains perfect.
Just some half ass correlation that is often significantly flawed like the cherry picked ice core samples that were debunked in Al Gore's stupid book or the false temperature data put out by NOAA or NASA under the Obama administration.
If all the data didn't say you were a cult fraud, you wouldn't have to auto-deny all the data. That's why you're called deniers. If it's inconvenient to the dogma of your political cult, you simply deny it, no thought required.
Substantial historical data indicates that CO2 doesn't lead temperature rise, its lags. You should see how the AGW scam artist try to dance around that one
Shakun (2013) says you're wrong. Your record of perfect failure remain unblemished.
Water vapor in the atmosphere, the output of the sun, earth's orbital cycles, natural methane release and volcanic activity and orther natural factors control the climate of the earth, not my gas guzzling V-8 Tundra pick up truck or your air conditioning.
All those natural factors had the earth cooling for the past 8000 years, and were continuing to push the earth towards cooling. Being that the current fast warming is in direct opposition to the natural cycle, it's really stupid to claim the warming is natural.
Many of these scientist that make good money on the scam have invented data to keep the scam going.
A cult bleater like you isn't worthy to sniff the jocks of those scientists. They're brilliant and honest, while you're stupid and corrupt.
Follow the money. All of it is going to the denier frauds you worship. Any scientist could get rich accepting denier bribes. They don't. They refuse your bribes, and that gives them even more credibility. On your side, all of your boys take those bribes. In contrast to the reputable scientists, almost everyone pushing denialism is getting paid specifically to push denialism.
Now, you? You're a lost cause. Like all deniers, you run solely on emotion. Getting the approval of your fellow political cultists is what drives you. The world will keep warming strongly, because that's what the science says, so the excuses you'll have to come up with will get crazier and funnier. That's why you're just comic relief now.
