THE National Resources Defense Council is an environmental activist group founded by law students and lawyers. Any goals
the NRDC can't achieve through persuasion or legislation, we assume, will be pursued by suing someone's pants off.
But we digress.
Persuasion is the technique employed in the group's report on U.S. counties said to be at risk of future water shortages due to
"climate change.” Even without the dire climatic changes that are theoretically possible between now and 2050, a number of
U.S. counties are at risk of water shortages. When computer modeling for climate change is factored in, the number swells to
one-third of all counties in the continental United States.
But this worst-case scenario isn't based solely on projected lack of precipitation. It also relates to growth patterns and
agricultural practices. Yet the NRDC's news release on the report is headlined (the emphasis is ours) "More Than One Out of
Three U.S. Counties Face Water Shortages Due to Climate Change.”
Rogers County, situated in one of the rainiest parts of the state, is among Oklahoma locales listed as being in "extreme”
danger of future water shortages. It's not the only rain belt county on that list: Virtually all eastern Oklahoma counties are listed
as having at least a moderate danger of future water shortages.
Oklahoma County and all adjoining counties but one are listed in the "extreme” category, but climate change isn't the reason.
Like Rogers County, this is a high-growth area that will need more water by 2050 regardless of whether climate change
adversely affects precipitation.
One's view of how seriously to take this report depends on one's view of global warming itself. Since we're among the skeptics
on the issue, we're also skeptical about NRDC's data and its motives for pumping it to an uncritical media.
Nevertheless, water shortages have been a fact of life for Oklahoma and most Western states. With or without ongoing
temperature rises, growth patterns will put stress on the water supply. Only seven of the state's 77 counties escape the
warning signs erected by the report. They're said to be at only a low risk of not having enough water by 2050.
Central Oklahoma's "extreme” listing, if true, is all the more reason it needs water from a lake in a county rated as having only
a "moderate” risk — and that particular risk assessment is one about which we're truly skeptical! The low risk of water
shortages in southeastern Oklahoma supports the argument that the state should sell excess water to counties in Texas with a
high risk for shortages.
It's clear that shortage predictions are based on consumption patterns as much as they are on climatic factors. In counties
where irrigation is depleting groundwater supplies, shortages may develop that have no relation to global warming.
The NRDC report is thus a persuasive if deceptive clarion call for radical climate change abatement policies.
