The people who scoff at global warming and apparently are against taking any action to alleviate the current trend usually cite the fact that there have been episodes of warming and cooling of the Earth for millions of years.
What they seem to ignore in their logic, though, is that there has always been a cause of the past global warming and cooling trends.
It is the cause that the many scientists have focused on in the current trend, and that is what is important.
If the disaster that will be caused by the continuing warming trend can be mitigated, shouldn't we do something about it?
