The Endangered Species Act may stave off extinction for the Delta smelt in California, but will it help this threatened fish – or any other at-risk species – recover and thrive again?
Storms coming? El Niño is projected to lead to much-needed rain in California next year.
El Niño is expected to bring heavy rains to drought-stricken California, but more rain alone won't solve the West's water crisis.
Really dry: a Colorado River aqueduct in southern California.
Historical analysis shows that natural forces are behind California’s drought, but global warming has contributed 8%-27% to the drought’s severity.
In a hotter, drier West, who, besides fish, will be most harmed?

Can California – and its massive agriculture industry – endure the drought without destroying its groundwater resources?
Universities on the leading edge.
With emergency water rationing in place, how are universities – and other major water consumers – going to conserve?
A broken paddle on parched earth, one result of four years of drought in California.
What explains the unusually dry and warm weather that's behind California's prolonged drought? And how is climate change contributing?
More land than water: almond trees account for 10% of the state’s water reserves, according to some estimates.
California is blessed with so much agricultural land that no matter how much the state conserves or produces, there will also be an economic incentive to consume more water.
California has been inundated with stranded, hungry sea lion pups, a result of warm waters causing fish to move.
The "warm blob" of remarkably warm water in the Pacific is changing weather patterns and impacting marine life, providing clues to how ecosystems may change in a warmer future.
In the 1920s and 1930s crews surveyed much of California, collecting information about vegetation. This photo was taken in 1936 by Albert Wieslander.

There are some barriers to linking our emissions reduction plan to California’s, but they’re worth overcoming.
As the pace of international climate negotiations has slowed, the interest and attention of international organisations and climate policy watchers has been diverted to national climate change responses…
