Global climate change is cyclic, we have the historical records to prove it. There have been ice ages and warm eras as well, droughts and floods for eons. That's the history of Earth.
However we can't discount the addition of billions of tons of man produced pollutants to the atmosphere as contributing to an increased severity of climate change.
True, it's too late to do anything about those that are there. We can't change the past.
But we can do something about future pollutants, and even benefit economically as well.
I think the biggest resistance to change is from those industries that see a threat to their bottom line.
Short term thinking has been a plague of innovation for a long time.
And that's what we're talking about, innovation.
An example: In the 1970s the U.S. automakers were vehemently opposed to emissions controls, as the cost would affect their profits. Now, thirty some years later, we have cars that run infinitely cleaner than their predecessors, get better fuel mileage and much better performance.
Semi tractor engines now make more than 500 hp while producing no (or very little) visible smoke.
Using technology to be "greener" is a good thing, the benefits are immense.
And the innovators will reap the profits.
BTW bio-diesel is still a hydrocarbon, and still produces the same pollutants as dino-diesel.
