water conflicts

Race to make the Earth look like the Moon

What with drought threatening large sections of the American West and South, perhaps it should not be surprising to see this article from the Chicago Tribune, "Great Lakes key front in water wars; Western, Southern states covet Midwest resource," in which the reporter warns:

With fresh water supplies dwindling in the West and South, the Great Lakes are the natural-resource equivalent of the fat pension fund, and some politicians are eager to raid it. The lakes contain nearly 20 percent of the world's surface fresh water ... Water levels of the Great Lakes are down substantially, and while that may be part of the historic cycle of ups and downs, water managers argue the region must jealously guard what is here

Even New Mexico Governor and Presidential candidate Bill Richardson couldn't resist the temptation to speculate on using the lakes. Fortunately, there is a concerted attempt to protect them:

Eight Great Lakes-area states, from Minnesota to New York, and two Canadian provinces have proposed a regional water compact that would, among other things, strengthen an existing ban on major water diversions outside the Great Lakes Basin, home to 40 million Americans and Canadians

U.S. states face water shortages

The catastrophic California wildfires got all the press, but it’s worth paying attention to an equally intimidating but slower-moving threat: water shortages. From Georgia to Massachusetts, Florida to New York, the Great Lakes to the West, U.S. states are getting thirstier. In fact, the government predicts that at least 36 states will face challenges from […]

The magnitude of drought and floods will increase with climate change

A very good article in the Washington Post lays out the problem we face.

"Global warming will intensify drought, and it will intensify floods," explains Stephen Schneider, editor of the journal Climatic Change and a lead author for the authoritative Intergovernmental Panel on Climate Change (IPCC). Why?

As the air gets warmer, there will be more water in the atmosphere. That's settled science ... You are going to intensify the hydrologic cycle. Where the atmosphere is configured to have high pressure and droughts, global warming will mean long, dry periods. Where the atmosphere is configured to be wet, you will get more rain, more gully washers.

The droughts will be especially bad. How bad?

Richard Seager, a senior researcher at Lamont-Doherty Earth Observatory of Columbia University, looked at 19 computer models of the future under current global warming trends. He found remarkable consistency: Sometime before 2050, the models predicted, the Southwest will be gripped in a dry spell akin to the Great Dust Bowl drought that lasted through most of the 1930s.

Population is not the short-term problem

Now and again some commentator will claim that we lack to resources to support our population sustainably -- either today or in the near future. But the fact is, even with current technology we have plenty of sustainable resources for our ~7 billion population and for the ~10 billion we expect in the future. What prevents this is not scarcity but folly and cruelty.

What are the constraints usually cited? There is soil and sustainable food production. But as I recently documented, we can feed ten billion sustainably if we choose to. There is freshwater, but as I documented, we have sustainable ways to deal with that as well.

What about energy? Right now we use about 14 terrawatts total primary energy world wide. The most conservative estimates of potential efficiency increases say we can double efficiency. And the most conservative estimates overlook stuff we are doing in some places at this very moment, including the potential for changes in material intensity and savings in thermal losses by producing electricity from mostly non-combustion sources.

But of course we are also going to have increased population and a lot of poor people who want to get richer. So it is not unreasonable to assume that a ten-billion-population world that consumes energy thriftily but lives a decent lifestyle with indoor plumbing, hot water, refrigerators, basic electronics, enough to eat, enough work, enough leisure, and plenty to do with that leisure will consume around 25 average terawatts worldwide.

Trends on an ever-shrinking planet

I was at Coop Power's excellent annual renewable energy summit in western Massachusetts recently. Richard Heinberg was there as a presenter. He discussed his well-regarded peak oil projections, and he then put that curve next to his peak uranium and peak coal projections. That visual drew gasps from the crowd -- especially the peak coal bit.

Sure we've got lots of coal, but its quality ain't what it used to be, and won't go as far. Check his data. This got me thinking of all the indexes we might put forward to track important trends on this ever-shrinking planet.

The next one I'd promote, given our perilous reliance on the mobile hives that are driven from farm to farm to pollinate our crops, plus this winter's mysterious honeybee population crash, would have to be peak bees. And how about peak freshwater. What would you propose?

Australia’s great drought

The Economist has a great article on Australia's crippling drought. If this is what global warming is likely to bring Australia, we should pay attention and hopefully learn something about how best to cope.

What Mexican activists can teach the U.S. about poverty and the planet

As the border organizer for Sierra Club’s Environmental Justice program, I bounce back and forth across the U.S.-Mexico border supporting grassroots environmental activists. More than the food, language, or currency, the biggest difference from one side to the other is what issues are considered “environmental.” Perhaps nowhere else on earth is there such a long […]

Tomasita González, environmental-justice organizer, answers questions

Tomasita González. What work do you do? I work as a community organizer at SouthWest Organizing Project, based in Albuquerque, N.M. What does your organization do? For over a quarter century, SWOP has worked to build an environmental-justice movement in disenfranchised, working, and people-of-color communities. In the ’90s, we sought to challenge the mainstream “Group […]
