is global warming man-made /sci/? or is it natural?

Liars are easy to expose.
[1] The truth is the opposite of what a liar says it is.
[2] The truth cannot support a lie. Only another lie can make the lie before it seem believable.

Are you asking me? It's weird that this is something that needs to be explained but a model fitted on already seen data does not provide any new evidence unless that model has been also validated on unseen data - in case of time series that would usually be future data. So how is the model on your picture doing if you extend it past 2000?

Bloated consumers don't want to believe they have a problem.

For example, try telling this fat fuck he needs to eat less. I bet he calls you a liar, lol. I bet he calls you every nasty name he can think of. I bet if he was capable of getting his greasy lard ass off of his cot, he'd even get violent.

>here, look, I made some subjective additions into a climate model that show temperature increasing more! Your farts totally heat the planet!

Now show the correlation between CO2 levels and temperature on 10^5 - 10^6 years scale. Oh, right, there is not one.

t.brainlet
The earth's natural Milankovitch cycles kick-start a feedback loop.
It does this first by cyclically warming oceans in the southern hemisphere, which begins a feedback loop that even you've probably heard of called "the greenhouse effect."

>On this pic, T does a trend first, then CO2 follows.
So when you claimed there was no correlation between the two, were you just misinformed or were you lying?

>I am hoping your goal was to demonstrate that CO2 levels do not influence T, but vise versa.
The goal was to demonstrate a correlation between the two, since you claimed there was none. We already know that CO2 influences temperature via the greenhouse effect.

get a load of this fuckwit who complains that a study comparing modeled to observed temperatures was published after the interval it models.
if you're comparing anything to observations, you have to wait to get those observations, you brainlet.

>>9889756
>I don't like this model so I'm gonna JAQ off about whether it takes into account water vapor
water vapor in the atmosphere exists in near-equilibrium with the oceans, dickhead. it's strictly controlled by temperature.

hey retard, you don't understand how correlation works.
given that variables OTHER than CO2 affect global temperature, there's no reason to expect the two to track exactly. taking two 15 million year trends and just comparing the average slopes is babby-tier stats, and it's telling that that's the kind of stupid bullshit that deniers have to resort to.
so if CO2 is just one of several controls on temperature, how might that be reflected in the Ma scale? well, you'd expect to see sudden CHANGES in CO2 (happening too fast for other factors to change appreciably) to be reflected as sudden changes in the temperature record. and indeed this is the case if you actually LOOK at figure 6 in Royer (2014).
>http://droyer.web.wesleyan.edu/Royer_2014_Treatise.pdf

bonus points:
>hey this CO2 record is derived from a bunch of different proxies with significant variability in both values at a given time and density of measurements in time
>let's just squash it down to a single average value

apparently you can think CO2 can't drive climate change, or you can have some idea of how stats work, but you can't do both.

don't just look at the pretty pictures; read the words too.
