Some may think that humanity's impending doom comes from the recklessness in which we treat our world. We consume and pollute without consequence or remorse.
Some may think that it comes from our out-of-control population growth. Like an evil tide, we flow over the land bringing destruction and mayhem to each and every corner.
Some may think that it comes from technology. That our limited intellect allows us to create things faster than we can understand them.
But the real truth is that it comes from our own arrogance. From our ability to easily lie and cover up the truth when it turns out not to be convenient to our world view. From our ability to justify our loathsome methods, if we think the cause is even mildly noble. From our belief that we can fool each other and won't ever get caught, even though history is proof to the contrary.
Our impending doom comes not from our possible changes to the climate, but from the scientists supposedly studying it using "scientific methods". When we can no longer tell the difference between aggressive marketing campaigns and real science, we've descended to a dangerous new low. One that will pull the rest of our edifices down on top of us.
