The point is that none of these previous events involved such rapid change as we're seeing now, but even if they did, so what? We know what's going on, it isn't hard to monitor. We've known how the greenhouse effect works for more than 2 centuries, we can measure the amount of carbon dioxide in the atmosphere, we know it's gone up just over 40% since the industrial revolution, we have a reasonable model of the likely results - not perfect of course for such a complex system, but we're seeing the sorts of results that have been predicted. Ice melting over the arctic, glaciers retreating, sea levels rising, more extreme weather and now a disruption to the jet stream. If this was, for example, the detection of a new astronomical object or fundamental particle there wouldn't be any question about whether it existed.
Exactly so. But if the new astronomical object were an asteriod that was predicted to hit the Earth in 20yrs and preventing this would require some effort and expense on the part of the rich and comfortable there would be deniers pointing out that many objects have struck the Earth in the past and life survived and besides it will probably just strike the ocean and nobody but environmental elitists care about the ocean and it's really just a hoax by astronomers to make them rich and we all know that those orbital mechanics programs can be tweaked to give any answer you want and besides the asteroid may contain precious metals we can mine and if it hit the middle east wouldn't we all be better off anyway and let's just wait because we're sure to invent some magic bullet to solve this problem in the next 19yrs.
