Taking Climate Change Seriously

Tom Friedman talks common sense on global warming, and I agree with him 100%:

“Climategate” was triggered on Nov. 17 when an unidentified person hacked into the e-mails and data files of the University of East Anglia’s Climatic Research Unit, one of the leading climate science centers in the world — and then posted them on the Internet. In a few instances, they revealed some leading climatologists seemingly massaging data to show more global warming and excluding contradictory research.

Frankly, I found it very disappointing to read a leading climate scientist writing that he used a “trick” to “hide” a putative decline in temperatures or was keeping contradictory research from getting a proper hearing. Yes, the climate-denier community, funded by big oil, has published all sorts of bogus science for years — and the world never made a fuss. That, though, is no excuse for serious climatologists not adhering to the highest scientific standards at all times.

That said, be serious: The evidence that our planet, since the Industrial Revolution, has been on a broad warming trend outside the normal variation patterns — with periodic micro-cooling phases — has been documented by a variety of independent research centers.

As this paper just reported: “Despite recent fluctuations in global temperature year to year, which fueled claims of global cooling, a sustained global warming trend shows no signs of ending, according to new analysis by the World Meteorological Organization made public on Tuesday. The decade of the 2000s is very likely the warmest decade in the modern record.”

This is not complicated. We know that our planet is enveloped in a blanket of greenhouse gases that keep the Earth at a comfortable temperature. As we pump more carbon-dioxide and other greenhouse gases into that blanket from cars, buildings, agriculture, forests and industry, more heat gets trapped.

What we don’t know, because the climate system is so complex, is what other factors might over time compensate for that man-driven warming, or how rapidly temperatures might rise, melt more ice and raise sea levels. It’s all a game of odds. We’ve never been here before. We just know two things: one, the CO2 we put into the atmosphere stays there for many years, so it is “irreversible” in real-time (barring some feat of geo-engineering); and two, that CO2 buildup has the potential to unleash “catastrophic” warming.

When I see a problem that has even a 1 percent probability of occurring and is “irreversible” and potentially “catastrophic,” I buy insurance. That is what taking climate change seriously is all about.
