    Almond Orchards in California: Healthy or Hazardous?

    Why California almonds get such a bad rap.

    Richard Seager Sees Hand of Climate Change in Drought

    California’s wet and snowy winter brings welcome relief from a years-long drought that has challenged the state’s water supply and agricultural system. But climate scientist Richard Seager of Lamont Doherty Earth Observatory offers words of caution: Remember what happened, because it will happen again.

    In High Sierras, Remnants of Ice Age Tell a Tale of Future Climate

    Aaron Putnam’s research in the California Sierras is part of an effort to study glaciers around the world—in Europe’s Alps, the Himalayas, Mongolia, Patagonia, New Zealand. He’s working on an important piece of the worldwide climate puzzle that can help us understand what’s ahead in a warming world.

    Californians Are Ready for Recycled Water

    Water reuse is a proven technology that can produce a drought-proof sustainable water supply. Yet historically, there has been some reluctance to adopt it here in the United States. Xylem commissioned a poll to try to better understand perceptions about recycled water in drought-stricken California. And the findings were eye-opening.

    The Human Contribution to the California Drought

    “Future extremes are going to occur more and more frequently. In planning, we don’t need to plan for the 2 degree warming that we are aiming for as a globe, we need to plan for the 10 degree increase in a day, or the year when there’s no water.”

    With El Niño, Be Careful What You Wish for

    In Southern California, a strong El Niño usually signals rain. Given that California is now in the throes of a severe drought, it seems like that should be a good thing, even if it comes with risk of floods. But the reality of climate is more complex and counter-intuitive than it first appears.

  • Ancient Pollen Points to Mega-Droughts in California Thousands of Years Ago

    Ancient Pollen Points to Mega-Droughts in California Thousands of Years Ago

    Ancient pollen spores that were in the air when mammoths roamed Southern California are providing new insights into historic droughts in the region, including how a series of mega droughts 25,500 to 27,500 years ago changed the ecological landscape.
