Over the past three years (and indeed, for 10 of the past 14 years) California has experienced a particularly deep drought. How bad is the drought? Is it the worst in the instrumental record? The worst in over a century? The worst in 1200 years? The worst “ever”? And why has it been so bad?…

Guest Post: Matthew Heberger Pacific Institute, Oakland, California New monthly water use data for California water utilities shows that residential water use varies widely around the state, and that the response to the drought has been uneven. Moreover, in some areas, residential use averages more than 500 gallons per person per day, indicating that we…

In a new study just published by the journal Sustainability Science (Springer), analysis from the Pacific Institute (with lead author Dr. Juliet Christian-Smith, now at the Union of Concerned Scientists) shows that many of the fundamental responses of California water users to severe drought actually make the state’s overall water conditions worse – that in the end,…

In the past few weeks, I have had been asked the same question by reporters, friends, strangers, and even a colleague who posts regularly on this very ScienceBlogs site (the prolific and thoughtful Greg Laden): why, if the California drought is so bad, has the response been so tepid? There is no single answer to…

Snapshots from the New National Climate Assessment After three years of intensive effort, research, writing, and review by hundreds of climate scientists, the latest update of the U.S. National Climate Assessment was released today. It includes many long, carefully prepared sectoral and regional studies, and covers the massive range of effects of climate change on…

The end of the rainy season in California is arriving in a few weeks, and the April 1st snowpack measurement, which is a key indicator of water conditions, is tomorrow. As we approach the dry spring and summer months, the scope and severity of California’s drought will become more apparent, but it is already clear…

In the last few months, as the severe California drought has garnered attention among scientists, policymakers, and media, there has been a growing debate about the links between the drought and climate change. The debate has been marked by considerable controversy, confusion, and opaqueness. The confusion stems from the failure of some scientists, bloggers, reporters,…

We’ve entered a new era: politicians can now talk loud and clear about the reality of human-induced climate change and the growing threats to humanity. With strong, unambiguous statements by President Barack Obama, Secretary of State John Kerry, Senator Sheldon Whitehouse, and a growing chorus of other top-level voices, the wholesale denial of climate science…

Droughts – especially severe droughts – are terribly damaging events. The human and ecosystem costs can be enormous, as we may relearn during the current California drought. But they are also opportunities – a chance to put in place new, innovative water policies that are not discussed or implemented during wet or normal years. In…

It is time to recognize the serious California drought for what it is: a bellwether of things to come; a harbinger of even more serious challenges to California water resources allocation, management, and use. The drought could end next month. It could go on for more years. But it will not be the last drought…
