carbon dioxide - ThisIsCommonSense.org

There is climate change going on. And some of it is attributable to increasing levels of Carbon dioxide (CO₂).

It is uncontroversial and quite politically convenient to say that — despite Al Gore’s infamous propaganda positing climate change dogma as An Inconvenient Truth. The worldwide “green” movement to “fight climate change” has been supported by trillions of tax dollars and the eager, lip-smacking glee of major media mavens as they trot out story after improbable story, linking every storm, warm spell, cold spell, and summer ice melt to “man-made global warming.”

But there is no real “settled science” as non-scientists like to term the case for anthropogenic global warming, because there are

troubles with the temperature data,
difficulties separating weather events from climatic trends,
problems identifying CO₂ level variations as the cause of climate change rather than as a result,
a certain amount of dunderheadedness using a statistical construct of “average global temperature” to track actual trends, and

so much more. But we do know about one extremely positive effect of increasing atmospheric carbon: it makes the deserts bloom.

Or, at least, greener.

Six years ago a study of satellite data concluded that arid regions have gone greener. Increased atmospheric CO₂ levels makes photosynthesis more efficient, allowing plants to use less water, thereby creating more leaves.

Earlier this year, however, Forbes reported that a NASA study had just demonstrated that expanded agriculture and silviculture in India and China were responsible for most of that greening — but if you compare the Forbes article with the original paper, the CO₂ contribution persists.

Atmospheric carbon is plant food, so to speak, and without it, life on the planet would die.

An awkward truth?

Truly “Green” Energy

“The remarkable thing about fossil fuels,” says science writer Matt Ridley, “is that when we use them, no other animal is deprived of its livelihood.”

In a fascinating talk, Ridley, the author of The Rational Optimist and other brilliant, eye-opening books, calls our attention to what really should be an obvious fact: “No other animal [than us Homo sapiens sapiens] wants to eat coal, or oil, or gas.” But, he insists, when we fell a tree for our fuel, “we deprive a woodpecker of its life.”

This helps explain why, in so much of the world, animal species are coming back, their populations growing. They are renewing because of our use of non-renewable energy. (Renewable energy, he says, is quite bad for the ecosystem.)

But that’s just one reason burning fossil fuels is a good thing. Another is increased carbon dioxide (CO₂).

“What?!?!” — I can hear the enviro-shrieks from here in my bunker. This weekend there were protests around the world about climate change.

But climate change may be a good thing.

Well, at least, the planet is getting greener. The Sahara’s getting greener. Much of the world’s landmasses are re-foresting — that’s even happening in Bangladesh.

I read about widespread reforestation in The Atlantic years ago. I’ve written about this and other greening before. But the reason isn’t simply because our fossil fuel reliance has made agriculture more efficient, thus requiring less land — that disused land can then grow wild, or cultivate non-agribiz plantlife. It’s also because CO₂ feeds plants.

The Amazon, Ridley says, is greener than it was mere years ago.

Could later industrial civilization be saving the planet from the depredations of earlier industrial civilization?

Yes.
