Study Finds Snowpack in California's Sierra Nevada to Be Lowest in 500 Years - The New ... - 0 views

  • Study Finds Snowpack in California’s Sierra Nevada to Be Lowest in 500 Years
  • After analyzing the data, the team determined with its model that snowpack levels as low as this year’s were a once-in-1,000-years event. But because of rising temperatures caused by human activities, the researchers said they thought that snow droughts would become much more frequent.

A Wet Winter Won't Save California - The New York Times - 0 views

  • In the United States, we experienced more than 80 “billion-dollar” climate and weather disasters in the last decade, and several have cost much more. The regularity of these episodes and the resulting damage shows that we are not prepared for the current climate, let alone a changing one that portends more weather extremes.
  • We are not arguing that the drought has been caused by climate change alone, or that all weather disasters have a link to climate change. However, the evidence is clear that many areas of the globe are experiencing increasing risks from weather and climate hazards. As with the California drought, climate change is an important thumb on the scale, increasing the odds of particular extremes in specific places.
  • In California, we can expect warmer winters and hotter summers, drier dry years and wetter wet years, and less water storage from snowpack in the mountains, which also controls flooding. This means more years with extreme fire danger, critically overdrawn groundwater, legal water rights that exceed the amount of water available and challenges to balancing trade-offs among water storage, flood control and environmental protection.

  • We have opportunities to rethink the fundamental structure of water rights and markets, re-engineer water storage to compensate for decreasing snowpack, update regulations and infrastructure to embrace water reuse and recycling, and regulate end-user pricing to encourage conservation. In short, we benefit from incorporating climate-related risks in planning for California’s future.

Farmers Are Feeling The Pain As Drought Spreads In The Northwest : NPR - 0 views

  • Nicole Berg's stunted wheat field is so short and sparse she doesn't think the combine can even reach the wheat without, as she puts it, eating rocks.
  • Berg is a dryland wheat farmer in the sweeping Horse Heaven Hills of southeastern Washington state. She shows off one head of half-turned golden wheat amid a sea of them. Besides being too short, the plant's kernels didn't fill out properly.
  • "See how the wheat head is curled like that?"
  • ...12 more annotations...
  • "And then you break into it, you might have some berries down here, but this will be empty. There is no wheat inside the wheat head."
  • Northwest farmers like Berg, and ranchers who depend on rain, are expecting what one farmer called a "somber harvest" this year.
  • On her ranch, Berg says she's also worried about 1,000 acres of native grass seeds she has to plant this year into dry soil for a government conservation program. She says with all the Western wildfires in recent years, the wild grass and forage seeds have become expensive. She hates to plant them in shallow, bone-dry soil only to lose the crop if there's not sufficient rain.
  • The Berg's aren't the only ones suffering. The region is parched from near the Canadian border clear to the edge of Nevada, with triple digit temps on the way making it worse.
  • Earlier this year, Oregon declared drought zones for eight counties, and six more have requested it since. Now the drought is rapidly expanding into usually cooler and wetter western Oregon, according to Ryan Andrews, a hydrologist for the state's Water Resources Department. He says the thirsty ground will absorb whatever rain comes, meaning streams and rivers will get little water.
  • Jeff Marti, a drought expert for Washington's Department of Ecology, says it hasn't been this dry since the 1920s.
  • "It's the story of the irrigation haves and the have nots," he says. "Meaning those folks who get their water from rivers or storage, are probably going to be fine for their irrigation needs. But the dryland users and the folks that have cattle that depend on forage on the rangelands may be more challenged."
  • Looking ahead, Marti says the warming climate may mean more rain for the Northwest, but also much less snowpack that melts sooner. That could stress water supplies even more.
  • A bit west of Alderdale, Washington, cattle rancher Gary Hess is also having a hard time with the drought. His grass-fattened mother cows bawl at their calves, wanting them to stay close and away from the cattle dog. But he only has enough irrigated pasture for a small part of his herd, the rest are on dryland range. So Hess recently sold 70 mother cows with calves at their sides to another operator in Wyoming. They had many more good calves in them, and he hated to see them go. But he has no dryland grass to keep them.
  • "When you have to sell younger cows, that's a disappointment," Hess says as he tears up a bit. "With the kind of weather we've had the last couple of years, and the drought and the lack of feed and lack of water, we just finally had to cut back."
  • This spring it's also been windy here, further drying out the landscape like a blow dryer. Hess is thinking he'll have to sell more cows soon just to survive. He says it's hard to lose animals and bloodlines that he's worked so hard to build up. He figures it could take him up to a decade to build his herd back up without going into debt.
  • Most ranchers say they don't have time to dwell on the trucked-off cattle or lost crops. They're busy applying for federal disaster aid. And they're also keeping an eye out for wildfires that are always top-of-mind in the dry, hot summer, but expected to be worse because of this year's terrible drought.

The Western Drought Is Bad. Here's What You Should Know About It. - The New York Times - 0 views

  • Drought emergencies have been declared. Farmers and ranchers are suffering. States are facing water cutbacks. Large wildfires are burning earlier than usual. And there appears to be little relief in sight.
  • A drought usually starts with less-than-normal precipitation (and what is normal varies from region to region). If the dryness persists, river flows and reservoir and groundwater levels start to decline. Warm temperatures have an impact, too, causing winter snowpack to melt faster, which can affect the availability of water throughout the year. Excessive heat also causes more evaporation from soils and vegetation, which can lead to crop failures and increases the risk of severe wildfires.
  • Experts with the United States Drought Monitor, a collaboration of several federal agencies and the University of Nebraska-Lincoln, assess the severity of drought in a given area, ranking it from moderate to exceptional.

  • It’s very bad, both in terms of the size of the affected area and the severity. The latest map from the drought monitor shows that all or nearly all of California, Oregon, Nevada, Arizona, New Mexico, Utah and North Dakota are in drought, and in large areas of those states conditions are “severe” or “exceptional.” Colorado, Idaho, Washington, Montana, South Dakota and southwestern Texas are also affected.
  • It is true that much of the West is normally hotter and drier than other parts of the country. Much of the Southwest and parts of Southern California are desert. Las Vegas, for example, averages about four inches of rain a year, about a 10th of the national average. Much of the rest of California has a Mediterranean climate, which can be wet in the winter but is hot and dry in summer.
  • The fall and winter are usually wetter in California and the Pacific Northwest, so that may help. A pattern of summer storms known as the Southwest monsoon may help in Arizona, New Mexico and other areas. But the monsoon is unpredictable — the 2019 and 2020 monsoon seasons brought so little rain they were referred to as “nonsoons,” and are one reason the drought is so severe this year.
