Everything goes through cycles because of change. I think it
was Hera****us who said, that you cannot step into the same river
twice.
I can thing of a way of testing whether global warming is actually
man-made-- as in medicine, for example, you stop all traffic of
cars with the exception of necessities such as ambulances,
fire trucks, delivery of food, etc.; you stop all airplanes and you
stop all fuel emitting factories for five years. If there is a
reversal
of North Pole melting and animal habitat changes, and there
is a return to a more stable climate, you might have grounds
for concluding the cause. You will also have an op****tunity
for designing a new democraphics in which people can live
in a cleaner more peaceful environment.
