Maybe you don't understand what the scientists are saying because you're not a scientist. But the only "scientists" expressing doubt about global warming now are paid flacks of energy companies. And even some energy companies are giving up their propaganda campaigns.

The essential problem, as I understand it, is that once greenhouse gases get into the atmosphere they stay there, for all practical purposes. And once they reach a certain level, the temperature of the earth begins to change (more in some places than others, for various complex reasons). And this has already started to happen. (Glaciers melting in Arctic, etc.)

That means, that unless we figure out a way of getting the gases out of the atmosphere, the changes that have already started will continue, even if every person on the planet stopped using fossil fuels, etc., tomorrow. (And every cow stopped emitting methane, which I think is also a problem.) So we have to figure out ways of reacting to a problem that has already started, and will continue to grow no matter what we do.

What do you mean? That scientists are getting their ideas from the public, rather than from their science? Who's doing that?

Don't pay attention to "popular fears." The populace screws up everything technical. The problem with global warming is how do we adjust to changes that will inevitably happen due to what we have already put into the atmosphere, whether we "stop travelling" or not. (And if we could work out a way of cleaning the atmosphere, that would be nice. Planting more trees, if I'm not mistaken, is one way to help, since they breathe in carbon dioxide, but that by itself won't solve the problem.)

The problem with dirty bombs is that they are essentially a bogeyman. But once someone gets a bogeyman into their head, it's pretty hard to get it out.
