Inconvenient Truth: Since Film Premiere, Little Change in Public Opinion


Since Earth Day, a number of polls have been released confirming that public opinion on climate change has changed very little over the past two years or since the premiere of Gore's An Inconvenient Truth. Conventional wisdom pegged Gore's film and media campaign as changing the nature of the debate in the public's mind, but unfortunately this interpretation doesn't hold up to the data. Americans already concerned about the issue have grown more intense in their feelings, while many others continue to disregard the problem.

The latest evidence is this Pew survey, that details the lingering divide in public perceptions among partisans on the topic, with this divide greatest among the college educated. For more background, see this column I wrote on "Going beyond Gore's message," a study I recently published reviewing two decades of public opinion data on global warming, this recent news analysis of polling trends, and this earlier discussion of what exactly accounts for the major gulf in perceptions among college educated partisans.

Is this why time speeds up as we age?

We take fewer mental pictures per second.

Mind & Brain
  • Recent memories run in our brains like sped-up old movies.
  • In childhood, we capture images in our memory much more quickly.
  • The complexities of grownup neural pathways are no match for the direct routes of young brains.

Trauma in childhood leads to empathy in adulthood

It's not just a case of "what doesn't kill you makes you stronger."

Mind & Brain

  • A new study suggests children who endure trauma grow up to be adults with more empathy than others.
  • The effect is not universal, however. Only one kind of empathy was greatly effected.
  • The study may lead to further investigations into how people cope with trauma and lead to new ways to help victims bounce back.

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

Videos
  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
