The Reasonable Middle Ground on Climate Change

It has become Republican dogma that climate change isn't happening. That it's impossible for puny humans to change the climate of this huge planet. That God wouldn't let it happen because, as James Inhofe says, he made a promise to Noah.

The press, afraid of being accused of siding with liberals, still gives conservative climate change deniers a fair hearing, often referring to climate change as a "controversial theory." The idea is that they have to give equal credence to both "sides" of the debate to be fair.

The problem is that the press has fallen into the Republican trap and let the conservatives define a false equivalence between the hard evidence of all serious climate scientists on one side, and a few hand-waving cranks funded by oil companies who say "we couldn't possibly hurt a planet this big" on the other.

The reality is that acknowledging anthropogenic climate change is the reasonable middle ground. Climate change deniers are on the rightmost extreme, and radical anti-humanists are the leftmost extreme. I was reminded of this by an essay that appeared in the Huffington Post. In it, Peter Jay Brown wrote:

We humans are merely passengers on the spaceship Earth. We produce nothing important for a healthy planet, but certainly spare no expense at taking what we need and then some. We are the ultimate planetary narcissists.

Guys like Brown are just as wrong as Inhofe. They whine when wind turbines kill a few birds. They romanticize nature, implying that animals are somehow nobler than men. The truth is, animals behave like the brutes they are. When random fluctuations in environmental conditions happen to favor one species they drastically over-reproduce and lay waste to the land and other species. Just like we do. The difference is that they're not self-aware and can't stop to think about what they're doing before it's too late. We are. And we need to take responsibility for the problems that we're causing. Now.

As the only intelligent tool-using species on the planet, we have become the owners and operators of planet Earth by default. Short of total thermonuclear war, any ecological damage we inflict on the planet will probably only result in our own demise, and not the end of all life on Earth. Life has flourished with high concentrations of CO2 in the past, and would likely flourish again, albeit after migrations and die-offs of certain species. The biggest effects of anthropogenic climate change will likely be inland droughts and flooding of coastal cities, starvation, widespread plagues, world-wide wars over declining agricultural, water and energy resources, and the decline and collapse of human civilization as we go the way of the dinosaurs.

However, if a big enough asteroid or comet smacked the Earth all life would perish, This has likely occurred at least once in the past. Similarly, when the Siberian Traps (volcanoes) erupted perhaps 90% of all species were killed.

If a comet chucked out of the Oort cloud takes a bead on Earth, only a technologically advanced space-faring human race will be able to prevent the destruction of this lovely blue planet. Countering a repeat of the Siberian Traps would be much harder, but in the long run the human race is the Earth's only hope of saving the planet from total destruction. 

One could argue that the Earth evolved humans as protection against the larger threats that it was vulnerable to in the past. It is thus our responsibility to further develop our technology to a point where we can save the Earth — and ourselves — from certain doom.

But the truth is, right now we are hurting the planet — and ourselves — with our excesses. The 2000-2009 decade was the warmest on record, and this past March was the warmest in history. Tornadoes struck Arkansas, Tennessee and Mississippi in January. They hit Nebraska, Kansas, Missouri, Indiana and Tennessee in February. In March and April tornadoes hammered the nation's midsection again, and Texas too.

Inhofe's invocation of God's promise to Noah is especially striking because Inhofe so completely missed the point. Noah didn't sit around waiting for God to build his ark. Noah built it because a flood was coming.

Climate change — including floods — is coming. The seven billion humans burning billions upon billions of tons of coal, gas and oil are mostly to blame for that change. We can't just sit around and expect God to clean up our mess.
