The CO2 levels were lower 2 million years when it was 10 degrees warmer in that part of Greenland. You said higher in your post (if I'm understanding you correctly)
The timescale of co2 increase really is not relevant, because we know its been colder coinciding with far higher CO2 levels.
I'm not misrepresenting anything. There is no causal relationship between co2 levels and temperature based on the geological record, which is why it's not referenced by proponents of anthropogenic climate change.
Their reasoning is literally: "we have no explanation other than the increase in co2", but that line of reasoning isn't valid in the absence of a good understanding of climate and temperature. All their predictions have been off (sea level changes, polar ice, weather, take your pick) and so much of what regulates the climate, such as the milankovitch cycles is not fully understood.
Saying "we dont know yet ie our field could have very little value in the short term" just doesn't get the attention or the funding the alarmists are getting "our field will save humanity from the greatest threat ever".
Contrast their model that hasn't made a single accurate prediction about anything, with the model of evolution that has made accurate predictions across the natural sciences for over 150 years and you'll quickly realize how little this shit has to with actual science.
Just to repeat, 30 years ago ago these clowns said it would be 5-10 degrees warmer now than it actually is because of rising co2. (Ironically, predicting no increase in temperature would have been a far more accurate prediction) and people want to do what these geniuses tell us.
