How climate deniers (‘skeptics’ is a misnomer I believe) see climate change evidence vs. how realists see it. For an explanation of the escalator graph, visit Skeptical Science. Skeptical Science has a ton of Climate 101 articles. They’re easy to read, are well sourced, and written by authorities in the field.

Update: For the haters (“Ermgerd! That chart is only 40 years!”), a longer time scale is here. For the temperature gauge skeptics go here. CO2 skeptics go here (scroll to ‘It’s Not Us’). Global cooling folks, go here. And, if you don’t like that source, some alternative sources on the science: here, here, and also here.

Look, I understand the skepticism. But at this point, skeptics have an incredibly high-bar to reach in order to be right. Science is a process of proving itself wrong, so skepticism is science’s middle name! Thus, if you want to really kill climate science you’ll have to show that carbon atoms do not retain energy. That’s the key. All other arguments against climate science have no relevance until the carbon-doesn’t-retain-energy argument is shown to be true.
