“Now, as global warming steadily melts glaciers and polar ice sheets, quickening the pace of sea level rise, scientists say that a severe shortage of river-borne sediment — most of it trapped behind dams — will increasingly be felt along the world’s coasts.”
The UCLA study highlights the inadequacies of decades-old infrastructure in the Golden State that were “designed for theclimate of the past and not for the rapidly changing climate of the future,” Climate Signals notes.
“Ourbig dams were designedto capture smaller floods than what we expect in the future,” said Daniel Swain, a UCLA climate scientist and lead author of an earlier study on California’sclimate-related weather extremes. “We can make some changes on the margins, but these structures were built for a climate that we no longer have.”
“The Klamath River project will be the most significant dam removal and river restoration effort yet. Never before have four dams of this size been removed at once which inundate as many miles of habitat (4 square miles and 15 miles of river length), involving this magnitude of budget (approximately $397 million) and infrastructure.
But perhaps more important than the size of the dams is the amount of collaboration and the decades of hard work that have made this project possible. American Rivers has been fighting to remove the dams since 2000. And thanks to the combined efforts of the Karuk and Yurok tribes, irrigators, commercial fishing interests, conservationists, and many others, our goal of a free-flowing river is now within reach.”
Biggest dam removal ever! Klamath was largest salmon producer until dams interrupted reproduction cycles.
The first shipment of highly radioactive sludge left an annex at the Hanford nuclear reservation’s K West Reactor Basin, which is near the Columbia River, at about 10:30 a.m. Monday. It was taken to central Hanford for storage away from the river.
“What is usually referred to as nuclear waste is used nuclear fuel in the shape of rods about 12 feet long. For four and a half years, the uranium atoms that comprise the fuel rods are split apart to give off the heat that turns water into steam to spin turbines to make electricity. After that, nuclear plant workers move the used fuel rods into pools of water to cool.”
Mr. Zinke said he had little interest in the governor’s job, and believed his next step would involve floating down a lot of rivers, learning how fly-fish better, and “being helpful to groom and advise the next generation of conservationists.”

There seems to be a lack of consistent principles behind Mr. Zinke’s DOE strategy.
