""The idea that human activities may influence climate has too many moneymaking activities attached to it to let mere science stand in the way.""

Take that thought and accept that there may or may not be a human element, then take the next step.

If no, what harm may efforts to reduce do?
If yes, what harm may efforts to reduce do?
In either case zero!
If yes, what harm may inaction do?

If not now, WHEN? If not us, WHO?

I am reminded of the Jewish mother with a sick son, who dosed him regularly with bowls of hot chicken broth.

"Will it help Momma?"......."CAN'T HURT SON?"
