I file this under politics because it is politics that is blinding us.
The oil industry* and their paid shills (known as deniers)** made a few waves recently when, in a carefully-worded survey of climate scientists, fewer than half were willing to single out carbon dioxide as the single greatest contributor to global warming.
“Half of all Scientists disagree with climate change!” was the nonsensical conclusion. A slightly-less-nonsensical conclusion was “Humans create carbon dioxide; if that’s not the primary driver of global warming, then warming is not because of humans.”
But let’s look at that for a moment. There’s another conclusion, and while it’s much more reasonable, it’s also much more scary: Carbon Dioxide isn’t the the primary driver of global warming any more. We’ve crossed a tipping point.
Meet Methane, and the point of no return.
While CO2 was the problem, there was something we could do about it: produce less CO2. Let the algae and the rain forests (whoops!) absorb the surplus back, and let our planet return to its previous equilibrium. We dithered, and denied, and the tundra began to thaw. Now the tundra is burping up enormous amounts of methane.
As a greenhouse gas, methane makes CO2 look like a punk kid with missing teeth.
So if many scientists don’t think Carbon Dioxide is the biggest contributor any more, that doesn’t mean they don’t believe the surface of our planet is getting hotter, it means that the game has changed. It means things have moved to a stage that we cannot reverse just by suddenly not being so selfish and short-sighted. It means there is nothing we can do to stop the change, and the sooner we turn our efforts to dealing with it, the less it will hurt.
But man, it’s gonna hurt.
