WASHINGTON – On global climate change, I’ve changed my mind – just slightly.
I’ve written about this issue for more than two decades and my theme has been monotonously consistent. As a starting point, I’ve accepted the prevailing scientific view that man-made greenhouse gases contribute to global warming.
But I’ve been routinely pessimistic and skeptical that we can do much about it. That is, we can’t easily control the forces that worsen global warming.
We have yet to discover or create some low-cost fuel that would replace fossil fuels – oil, natural gas and coal – which provide roughly 80 percent of the world’s energy. Most nations aren’t willing to scrap the energy status quo – the very basis of modern civilization – before having a practical substitute.
