Earth's environment is not fragile

Neil Reynolds:

Stanford University physicist Robert Laughlin says governments – and people generally – should proceed with more humility in dealing with climate change. The Earth, he says, is very old and has suffered grievously: volcanic explosions, floods, meteor impacts, mountain formation “and all manner of other abuses greater than anything people could inflict.” Yet, the Earth is still here. “It’s a survivor.”

Writing in the summer issue of the magazine The American Scholar, Prof. Laughlin offers a profoundly different perspective on climate change. “Common sense tells us that damaging a thing as old as [Earth] is somewhat easier to imagine than it is to accomplish – like invading Russia.” For planet Earth, he says, the crisis of climate change, if crisis it be, will be a walk in the park.

Relax, Prof. Laughlin advises. Let it be. “The geologic record suggests that climate ought not to concern us too much when we gaze into the future,” he says, “not because it’s unimportant but because it’s beyond our power to control.” Whatever humans throw at it, in other words, Earth will fix things in its own time and its own way.

Prof. Laughlin is the co-recipient of the 1998 Nobel Prize for physics. Brilliantly imagined, incisively expressed and vastly entertaining, Prof. Laughlin’s essay on climate change (What the Earth Knows) has been adapted from his forthcoming book on the future of fossil fuels. (His 2008 book, The Crime of Reason, documented pervasive government and corporate “sequestering” of scientific knowledge.)

You can’t discuss climate change, Prof. Laughlin says, without looking backward across geologic time. He puts ordinary rainfall into perspective to illustrate the point. The rain that now falls on the world in a normal year measures a metre – “about the height of a golden retriever.” The rain that has fallen since the beginning of the Industrial Age measures 200 metres. The rain that has fallen since the age of dinosaurs would fill Earth’s oceans 20,000 times. The rain that has fallen since oxygen formed would fill the entire world 100 times.

Yet, the amount of water in Earth’s oceans hasn’t changed significantly in all of this time. In Earth’s most recent glacial melting, 15,000 years ago, the sea level rose by one centimetre a year for 10,000 years – and then abruptly stopped. The heat required to produce this melting was 10 times the total energy consumption of all human civilization.

Excess carbon in the atmosphere? It happens all the time. And Earth deals with it. Anything that humans do to mitigate it will be a waste of time. Governments and citizens delude themselves when they think they can make a difference.

This guy makes more sense to me than AlGore ever has. I have often made the argument that the earth is not as fragile as environmentalist make it to be. I have seen weeds growing rampantly around the scene of old oil spills. If you drive through the country you will see abandoned houses that have been overtaken by the growth of vegetation, and this is just homes built in the last century. Scientist are finding whole civilizations works overgrown by jungles.
