Why are climate extremists so delusional?

why make this thread

>it was at 7000 in the past and the planet is still here

They cannot be that accurate with past readings. No way in hell.

t. climate experts

Not with atmospheric readings. You can only determine surface readings from ice cores

>They cannot be that accurate with past readings. No way in hell.
So it might be even worse then they claim?
Or does your skepticism only serve your rightist emotional needs?

>pic in OP
You know why he made this thread.

No, I have no idea which way it could go. I just do not trust any climate graph that they present with anything that far back.

This.

retards detected its called ice samples fucking dumb asses we know the climate of the world for millions of years

Odd that the graph stops at 400,000. Is there something slightly beyond 400,000 that you're not wanting us to see?

Why would you want look any further back. The time frame is already far too extreme.

oh but if there's a marginal increase now it will cause a runaway greenhouse effect and Earth will end up a barren inhospitable hellscape like Venus

Liberalism is a mental illness.

If the average is 250 ppm an increase in 80 ppm is over 30%. How is that not significant?

>Ice samples in the ground are an indicator of the presence of CO2 in the stratosphere.

Yes they are, there is a margin of error that lots of pro global warming people like to ignore but you do get an idea of atmospheric conditions in ice samples.

fuck you nigger

If Matt Damon of all people can science his way out of certain death on Mars, I'm sure we'll find a way to survive. Collectively, we're all much smarter than he is.

How do we know historical co2 levels?

The fact that the total change to the entire atmosphere is so many zeros away from the decimal point when looking at the grand picture.

CO2 dissolves in the water and the amount at the surface is proportional to that in the atmosphere.

Do you really deny climate change because you just dismiss all the science without even reading it?

Pol is the first place to pull out all the statics and literature possible on niggers but when it comes to climate change they act like retarded liberal bernouts

This is the fucked up thing about all this, its not about the survival of the white race we can take a few knocks and keep swinging, its the niggers and other assorted retards of the earth who will suffer the most due to climate change, and its them who are causing the most amount of pollution, this is all just another example of white mans burden.

97% is itself a made up statistic. If you're going to use fake studies to support fallacious reasoning, then you don't have much of a leg to stand on.

If climate change alarmists continue to rely so heavily on this fake statistic, it's going to start looking like you don't have any real evidence to support your case.

Got anything else? Maybe something actually convincing?

So? Just because it's a small number doesn't mean it is not a significant change. Small quantities can have large effects.

Concentrations in ppm and ppb are used in analyzing all sorts of things like heavy metals in water, which can have quite toxic effects at that level.

Polar caps have frozen co2 samples, and by how deep they are you can judge how old they are.
A better question about this subject is: Why does carbon dioxide emissions matter?

400 ppm is not a big deal and the CO2 has been much higher and life thrived. Especially plant life and at one time forests went from pole to pole. What is unusual is ice caps. For the first 3.8 billion years out of 4 billion the earth didn't have ice caps. The earth's rotation is slowing down, the internal heat is cooling and we the atmosphere was thinning. all leading to a nasty cool down. We are lucky we pump CO2 into the atmosphere.

There are other ways to find data past 1 million years, however they rely on more assumptions.

One reason you can't find ice back then is the Eocene epoch. The earth was 12 degree C above todays temperature. It had what they guess to be about 500 ppm CO2 and forest went from pole to pole. No ice. Early primates (humans) evolved because of high oxygen. The most new species evolved. It was a glorious time for life.

hey, he was wicked good at math in that one movie
