WHAT OTHERS SAY: Climate change is no longer up for debate

Tuesday, May 20, 2014 | 12:54 p.m. CDT; updated 6:24 a.m. CDT, Wednesday, May 21, 2014

Climate change is real: Debating the reality of climate change is a waste of time. Debating what to do is not.

The recent report on climate change from the U.N.-chartered Intergovernmental Panel on Climate Change is a sober reminder that what we as individuals happen to "believe" about global warming €"unless we happen to be climate scientists€" has absolutely no bearing on whether the phenomenon is a vast hoax perpetrated by 99 percent of the scientific community or a looming crisis that, as the report underscores, will affect everybody on this planet.

Skepticism on most issues is, indeed, healthy, but in any number of areas, whether it's relying on M.D. Anderson for cancer treatment or a Texas A&M-trained civil engineering fund to erect bridges and skyscrapers, we have to trust the experts.

So it is with measuring and assessing the evidence of climate disruption. As conservative columnist Michael Gerson pointed out in the Washington Post recently, "Our intuitions are useless here."

The report from the scientists, economists and other experts on the IPCC panel is about as sobering as it can get. The panel warned that the planet is indeed warming, that humans are primarily responsible and that we are not anywhere near prepared for the dire consequences.

What's coming if we can't or won't change our ways are low-lying island nations disappearing, coastal cities going the way of Venice (at best), abnormal weather patterns and growing seasons and tropical pathogens migrating into formerly temperate zones.

In Texas and elsewhere, change already is upon us. We're seeing increased rates of water loss, depleting water resources, increased wildfires and the spread of invasive species. Our grandchildren and their children will see a rise in sea level from 1 to 4 feet by the end of the century.

"Climate change is no longer a future issue," Katherine Hayanoe, director of Texas Tech's Climate Change Science Center, told the Houston Chronicle recently. "For the United States as a whole, climate change will affect our lives through its impacts on our health, our water resources, our food, our natural environment and our economy."

Debating the validity of climate change "or whether we believe in climate change" is a waste of time; debating what to do in response is anything but a waste.

According to the IPCC report, emissions of heat-trapping greenhouse gases grew faster between 2000 and 2010 than over the previous three decades. That disturbing statistic is despite real progress being made in some parts of the world. In Germany, for example, Chancellor Angela Merkel has laid out a plan to fill more than 40 percent of her nation's energy needs from renewable sources.

The United States has reduced its carbon emissions by nearly 10 percent since 2005, in part because of stricter automobile fuel economy standards but also because of the lingering recession. Progress, though, pales in contrast to the increase in emissions by China and other rapidly industrializing countries.

We know what needs to be done, but if we can't summon the political will and the sense of worldwide urgency to implement some kind of carbon tax or to develop new technologies that limit future carbon emissions, then we need to begin preparing for the worst.

That means reassessing where we live and where we build, how we feed ourselves and how much water we use, among numerous other major adjustments.

We are not going to "fix it". We are not going to reduce the fossil fuel usage of the first world by 90% in 20 years and we are not going to make the developing world develop only with low carbon fuels. It's too painful. That's what many mitigation advocates leave out of the equation.

We'll adapt. Or not. It's not worth it to make pathetically insignificant changes in how we get our energy. If we are not willing to advocate severe and immediate rationing of fossil energy, then we may as well do nothing.

Adaptation should be the only focus in planning.

Mark:

"To the truly simple, everything is simple."

I agree that the large quantities of carbon dioxide we generate from burning fossil fuels are a bad thing.

During a series of 36 half hour TV lectures, Professor Michael Wysession of Washington University (St. Louis)* reminds us that it is accepted from geological evidence that there have been at least five (5) global warming episodes in Earth's geological history - none of those episodes attributable to mass burning of fossil fuel.

Obviously, global warming can be caused by various means, but I'm willing to agree that our present situation is being "fueled" by human activities.

Adaptation is the ONLY short term option. There ARE no other sort term options.

Several times I've pointed out that our atmosphere is a HUGE system. Such systems are incapable of close human control, even under the best of circumstances. If we were to immediately employ world wide draconian measures there's no guarantee of a "quick turnaround" for such a large system, especially if we may ALREADY have passed some irreversible tipping point.

Our collective ignorance is only surpassed by our false belief that we can control the physical world rather than it controlling us. One aspect of being "technically educated" is the realization of how limited our ability to control the physical world truly is.
