California will help return tribal lands as part of the historic Klamath River restoration – the Los Angeles Times

The Klamath River runs more than 250 miles from Oregon’s high desert interior to the Pacific Ocean in northern California and is the site of the world's largest dam removal project. The dam decommissioning effort, which is intended to improve water quality and fish habitat, includes restoration of 2,000 acres formerly overtaken by the hydroelectric dams, which were built between 1918 and 1962 (Courtesy of Oregon State University, CC BY-SA 2.0 via Flickr).

More than a century has passed since members of the Shasta Indian Nation saw the last piece of their ancestral home — a landscape along the Klamath River where villages once stood — flooded by a massive hydroelectric project.

Now more than 2,800 acres of land that encompassed the settlement, known as Kikacéki, will be returned to the tribe. The reclamation is part of the largest river restoration effort in U.S. history, the removal of four dams and reservoirs that had cut off the tribe from the spiritual center of their world…

Scientists warn that a crucial ocean current could collapse, altering global weather – the Los Angeles Times

The Atlantic Meridional Overturning Circulation acts as a conveyor belt of ocean water from Florida to Greenland. Along the journey north, water near the surface absorbs greenhouse gases, which sink down as the water cools near Greenland. In this way, the ocean effectively buries the gases deep below the surface (Courtesy of NASA's Goddard Space Flight Center, caption by Ellen T. Gray)

Scientists warn that a crucial ocean current could collapse, altering global weather…The Atlantic Meridional Overturning Circulation, or AMOC, is a system of ocean currents that circulate water in the Atlantic Ocean like a conveyor belt, helping to redistribute heat and regulate global and regional climates. New research, however, warns that the AMOC is weakening under a warming climate, and could potentially suffer a dangerous and abrupt collapse with worldwide consequences…
