For a long time I was in the "we don't have enough information to make a conclusion" camp, and dismissed anyone "jumping" to conclusions as alarmist. This xkcd changed my mind: https://xkcd.com/1732/ https://xkcd.com/1732/

The graph that convinced me (many years ago) was this one: http://www.jeremyrhammond.com/wp-content/uploads/2016/03/mauna-loa-co2-619x484.jpg http://www.jeremyrhammond.com/wp-content/uploads/2016/03/mau... It is simple physics as to how CO2 works as a greenhouse gas. Seeing the clear trend of increasing CO2 in the atmosphere makes warming sort of obvious (at least to me). All of the complex second order effects (how much warming, how climate and weather patterns will react, and so on) are much more complicated and therefore less clear. Nevertheless, we are having a strong clear effect on the atmosphere which is going to warm the planet. The rest is details (though those details are getting a lot scarier, recently).

Much as I like Randall Munroe and xkcd, I don't see any sources cited in that comic. I don't know that we know, precisely, how fucked we are yet, but I do think it's clear that humans are having an effect, and we know very convincing reasons for why we're having an effect, so we should work to reduce that effect regardless of whether we're fucked in 100 years if we continue this way, or if it will take 1000.

  He cites his sources on the right near the top. > SHAKUN ET.AL. (2012), MARCOTT ET.AL.(2013), ANNAN AND HARGRAVES (2013), HADCRUT4, IPCC

    I stand corrected. Thanks.

I would've liked that comic illustration much more if he had gone back 400,000 years instead of only 20,000.
