We’ve all heard
time and time again that greenhouse gas from fossil fuel is warming the
atmosphere and action is needed urgently.
I’ve been
hearing that for 15 years now, since I began my watch on the issue. Climate
experts told us in the early nineties that warming evidence was still
uncertain.Another one or two decades
would provide proof. The evidence is still weak and the scientific debate
goes on.
For the sake of
evaluation we can postulate thatgreenhouse gases must be controlled. Lets make that assumptionand move forward to consider how they might
be managed.
