You're point that "we have genius scientists" is so stupid. Sure, we have some smart scientists, but they are chafing under restricted funding and freedom. They can't do shit without money and support. And the greatest hurdles to overcoming global warming are ECONOMIC, not scientific. We need gas taxes and corporate R&D - both of which will not arise without public support.
You can give them that support. You can support companies which support that as well. You can make a difference, because you're one of the richest people in the world, even if you only make 10 bucks an hour.
Worry serves an important function - it tells us that there's something we need to watch out for, and perhaps address.
