But that is not what the problem is. In any scientific discipline, we never know anything for certain. Climate deniers are not saying, "we still don't know some things about climate change." They are denying the basic facts of climate change because they are ignorant or self-serving, or both. To not point this out and address it with equal fervor – especially given what's at stake – is just as much a slight to climate science. By all means, in the scientific field, maintain humility and approach each result with skepticism. But #1 is more a political problem than a scientific one. The nation's (and world's) response to climate change is vastly insufficient. As educated individuals in a high-tech field, we have a duty to call a spade a spade, and sometimes preemptively calling the opposition's bullshit is a means to this end.
