With the drought stretching into its fourth year, a heavyweight water agency from Los Angeles has come calling on Sacramento Valley rice farmers, offering up to $71 million for some of their water.
The price being offered is so high, some farmers can make more from selling water than from growing their rice. Many are willing to deal: Nine irrigation districts, mainly serving rice growers along the Feather River basin, have made tentative deals to ship a portion of their water to the Metropolitan Water District of Southern California and several other water agencies later this summer.
Researchers at The University of Texas at Austin's Institute for Geophysics (UTIG) in the Jackson School of Geosciences have discovered two seafloor gateways that could allow warm ocean water to reach the base of Totten Glacier, East Antarctica's largest and most rapidly thinning glacier. The discovery, reported in the March 16 edition of the journal Nature Geoscience, probably explains the glacier's extreme thinning and raises concerns about how it will affect sea level rise.
Totten Glacier is East Antarctica's largest outlet of ice to the ocean and has been thinning rapidly for many years. Although deep, warm water has been observed seaward of the glacier, until now there was no evidence that it could compromise coastal ice. The result is of global importance because the ice flowing through Totten Glacier alone is sufficient to raise global sea level by at least 11 feet, equivalent to the contribution of the West Antarctic Ice Sheet if it were to completely collapse.
Sea-level rise of 15 centimeters (about 6 inches) and more will require implementing adaptation strategies such as water conservation, wastewater reuse, recovery and recharge, stormwater storage, alternative water supplies including desalination, and other advanced water-management strategies in order to assure adequate water supplies (Heimlich et al., 2009).
