Climate Change Deniers could play it safe, just in case they're wrong, right?

It's hard to know what will eventually change the minds of those who deny environmental problems. From Thom Hartmann's email newsletter:

Attention climate change deniers - the planet is rapidly heating up. The National Oceanic and Atmospheric Administration is out with a new report showing that the last year - from June of 2011 to May of 2012 - was the hottest year ever since NOAA began recording annual temperatures. That included the fourth warmest winter - the second warmest summer - and the warmest spring ever recorded. On top of that - the science journal Nature is also out with a new report warning that the planet is reaching a tipping point - and its ecosystems are on the verge of irreversible change, which could mean disaster for humans.

The report even warns of the possible extinction of our species within just a few generations, once this tipping point is reached. Something has so badly rotted in our culture that we no longer look out for future generations - or care about leaving them a habitable planet. Instead - we care just about short-term profits for oil barons in Texas and Kansas, and it could cost us everything our species has worked for.
