The Freshwater Boom Is Over/Our Rivers Are Starting To Run Dry

The Freshwater Boom Is Over

The freshwater boom is over. Our rivers are starting to run dry

We can avert global thirst - but it means cutting carbon emissions by 60%. Sounds ridiculous? Consider the alternative

It looks dull, almost impenetrable in places. But if its findings are verified, it could turn out to be the most important scientific report published so far this year. In this month's edition of the Journal of Hydrometeorology is a paper written by scientists at the Met Office, which predicts future patterns of rainfall and evaporation.

Those who dispute that climate change is taking place, such as Melanie Phillips of the Daily Mail, like to point out that that the predicted effects of global warming rely on computer models, rather than "observable facts". That's the problem with the future - you can't observe it. But to have any hope of working out what might happen, you need a framework of understanding. I…

Trade Off Looms for Arid U.S. Regions. :Water or Power?

Trade Off Looms for Arid U.S. Regions: Water Or Power?

Trade-off looms for arid US regions: water or power?

Albuquerque, N.M. - The drive to build more power plants for a growing nation – as well as the push to use biofuels – is running smack into the limits of a fundamental resource: water.

Already, a power plant uses three times as much water to provide electricity to the average household than the household itself uses through showers, toilets, and the tap. The total water consumed by electric utilities accounts for 20 percent of all the nonfarm water consumed in the United States. By 2030, utilities could account for up to 60 percent of the nonfarm water, because they use water for cooling and to scrub pollutants.

This water-versus-energy challenge is likely to be most acute in fast-growing regions of the US, such as the Southeast and the arid Southwest. Assuming current climate conditions, continued growth in these re…
