Please remain calm: The Earth will heal itself - The Globe and Mail
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.What the Earth Knows - Laughlin
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.

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.

The Earth regulates climate change in geologic time, Prof. Laughlin says, “without asking anyone’s permission or explaining itself.” If the Earth determines that Canada should freeze again, the best response would simply be to sell your Canadian real estate. The Earth moves on, Prof. Laughlin says. So should we.
Global warming forecasts have the further difficulty that you can’t find much actual global warming in present-day weather observations. In principle, changes in climate should show up in rainfall statistics, hurricane frequency, temperature records, and so forth. As a practical matter they don’t, because weather patterns are dominated by large multi-year events in the oceans, such as the El Niño Southern Oscillation and the North Pacific Gyre Oscillation, which have nothing to do with climate change. In order to test the predictions, you’d have to separate these big effects from subtle, inexorable changes on scales of centuries, and nobody knows how to do that yet.
