How about this, a comprimise. there are many many factors that go into the tempature of the earth. not just co2 levels, for anyone to predict future temps is insane to base it on co2 levels. it is a fact that in 2 weeks the earth itself (through active volcano hot spots and oceanic methane beads) contributes more in volume to the equation than humans do in 1 year.
what yall need to understand is that the earth is still cooling down from when it got hit by another celestial object (which created the moon) overall we are still cooling, you only have to drill a mile before you hit the mantel which is liquid magma. as time goes on, and the earth cools, the crust will thicken, so this idea that "global warming even exists is a crock of shit that the government made up based on short term data to pass cap and tax. and 250,000 years is short term when you consider the earth is about 5 billion years old thats 5,000,000,000. al gores data is only based on .005% of the earth's history
btw im totally stoned i hope that makes sense
