Why doesn't mainstream media care about climate change?

There is much to be desired in the mainstream media's coverage of energy politics and climate change, but perhaps the single most important fact that gets consistently overlooked -- that is scarcely apprehended by the general public and yet comes to mind for me every time a new pipeline or oil field gets approved -- is that greenhouse-driven warming operates on an extremely delayed timescale. As with several aspects of climate science, that timescale is impossible to deduce with perfect accuracy, but NASA climatologist James Hansen estimates that 60 per cent of the total climatic response to a shift in greenhouse gas levels occurs after 25-50 years.
