I do think, however, that there's a significant difference between "catastrophic" and "existential." Catastrophes occur regularly, but entire civilizations don't collapse very often. Thus it seems very different to me to say, "We must do X or the Muslims will establish a worldwide caliphate and all our women will be wearing burqas," as opposed to saying, "We need to do X or there is a high probability that some catastrophic events will occur." I made no assumptions about whether you had seen any data previously. You asked for a source of data that shows global warming is an "existential" threat. I responded with a link to data that show, in a non-hysterical way, what the threat is. I guess what this whole exchange arose from was my inference, probably incorrect now that I think about it, that you were saying that anybody who believes global warming is real and a problem is as loony as people who think the muslims are going to destroy us. My original response was "There seems to be a lot more evidence that global climate change may have significant negative consequences than there is to support the idea that a few thousand radical muslims are going to take over the world." I'll stand by that statement. You've agreed that the data showing terrorism to be an existential threat is nil. I have supplied data that show that global warming may have significant negative consequences. But the statement I was responding to included a reference to Chicken Little, so I should have realized that you were referring only to the people who get hysterical about either problem. Is that a fair interpretation of what you said? - Allen PS: Sorry for being so long-winded about it.
