dos ekk.. I see that you have trouble following....
We are not talking about polio vacines here. We are talking about predicting the future. Scientists have a very poor record of that. Even something as simple as a polio vacine... they would have a much better chance of inventing it than of predicting when it would happen or.... even if.
You seem to be saying tho that if they are smart enough to cure polio then they most certainly can predict and understand global climate.
You might just as well as said that since they can't even cure the common cold... they have little chance of predicting the weather for next week.
