Mountains Inspire Winners of San Dieguito Water District 2023 Landscape Contest

/in , , /by /Water News Network

Large trees were the driving force that led Encinitas homeowners to remove grass and create a vibrant, low-water use landscape. The waterwise transformation won the San Dieguito Water District 2023 Landscape Makeover Contest.

Rick and Melanie Cullen had a yard with grass with large shade trees. But the roots of their three large Liquidambar trees were damaging the driveway and the grass, which motivated the couple to remake their landscape.

Lorelei Cloud Makes History in a Critical Time as First Tribal Council Member on the Colorado Water Conservation Board

/in , , /by /CPR Newsby Tom Hesse

Lorelei Cloud joined the Colorado Water Conservation Board in March as the first tribal council member to serve in the position.

Cloud, the vice chair of the Southern Ute Tribal Council, was appointed to the position by Gov. Jared Polis. She joins the board at a critical time for water not just in Colorado, but across the American West.

As the representative for the San Miguel-Dolores-San Juan drainage basin, she represents land that covers not just the Southern Ute and Ute Mountain Ute reservations, but also 10 counties in southwestern Colorado.

She spoke to Colorado Matters about including Indigenous voices in water discussions and the challenges ahead for the Colorado River.

County Largely Disagrees With Grand Jury’s Finding on Drought, Water Sources

/in , /by /San Clemente Timesby Breeana Greenberg

As the Orange County Board of Supervisors looked to submit its responses to this year’s slate of Orange County Grand Jury reports, the supervisors held an in-depth discussion on one report in particular: “Historic Rain Yet Drought Remains.”

Board members on Tuesday, Aug. 8, discussed the county’s recommendation to partially disagree with certain parts of the report, which largely found that South Orange County’s reliance on imported water will be impacted by climate change and must adapt.

Maui’s Fire Became Deadly Fast. Climate Change, Flash Drought, Invasive Grass and More Fueled It

/in , /by /AP Newsby Claire Rush, Seth Borenstein, Jennifer McDermott

Hawaii went from lush to bone dry and thus more fire-prone in a matter of just a few weeks — a key factor in a dangerous mix of conditions appear to have combined to make the wildfires blazing a path of destruction in Hawaii particularly damaging.

Experts say climate change is increasing the likelihood of these flash droughts as well as other extreme weather events like what’s playing out on the island of Maui, where dozens of people have been killed and a historic tourist town was devastated.

The Cullens wanted to plant a drought-tolerant, water-wise yard that would be easy to maintain, beautiful, and hold up to their frequent travel schedule.

“My inspiration was to create a water wise, drought-tolerant front yard that also provides us a beautiful yard as if we were in the mountains,” said Melanie Cullen. It started with taking existing small landscape rocks and repurposing them into a natural dry streambed feature.

Colorful plant palette pollinators love

Plants were selected that would thrive in the coastal San Diego County environment. The invasive Liquidambar trees were replaced by Blue Ice Cypress, Forest Pansy Red Bud, and dwarf Deodar Cedar trees. Colorful drought-tolerant flowering shrubs and perennials including Coastal Woolybush, salvias, echinaceas, Texas primrose, heronsbill, columbine, Grevillea ‘Mt. Tamboritha’ and ‘Sour Grapes’ Penstemon provide habitat for pollinators.

Fragrant ground cover

Grasses including Pennisetum ‘Fireworks’ and Acorus ‘Variegated Sweetflag’ add to the plant palette. Creeping Thyme and trailing Rosemary are used as colorful, fragrant ground cover.

A highlight: one dozen Azaleas create a woodland flower look. Cullen says they bloom when other plants aren’t flowering.

“One might think they are water hogs, but they get the same water as everything else and bloom quite a bit throughout the year,” said Cullen. “It was a matter of choosing the right type of Azalea (Red Bird and Alaska White).”

Drip irrigation system saves water

The Cullens used a drip irrigation system that encircles each plant individually to direct water to the specific plant. They already had a smart irrigation controller which is still in use. A remote moisture sensor was added allowing the homeowners to monitor the ground moisture at the plants and then adjust watering for the yard.

Three to four inches of bark mulch helps retain irrigation, which has worked “extremely well.”

Tapping rain

Melanie Cullen says the irrigation was turned off completely from January through May due to generous rainfall. “Presently, we only need to water once every one to two weeks for 20 minutes,” she said.

“I join our Board of Directors in recognizing the leadership of the Cullens and commend them for taking proactive steps to improve our community’s resilience to a changing climate,” said Isam Hireish, General Manager of San Dieguito Water District. “I encourage all customers to utilize water more efficiently and take advantage of the various water-saving incentives we offer.”

In the months since the landscape makeover, the Cullens report all their original goals were met. “We love sitting in our front now and watching the many hummingbirds that also love our yard,” said Melanie Cullen.

Water-Short Cities in the West Want to Use Every Last Drop, Even When it Comes from Sewage

/in , , /by /KUNCby Alex Hager

It looks like a normal glass of water. It’s clear, cold and tasteless. But just a few hours ago, it was raw sewage.

That water is the end product of a process and technology known as water recycling, or direct potable reuse.

In the Western U.S., there’s more demand for water than there is supply, particularly in the Colorado River basin. While the region’s policy makers are mired in standoff about how to fix that imbalance at a broad level, cities with finite water supplies are finding creative new ways to stretch out the water they already have. In some places, that means cleaning up sewage and putting it right back in the pipes that flow to homes and businesses.

Scientists Look Beyond Climate Change and El Niño for Other Factors That Heat Up Earth

/in , /by /AP Newsby Seth Borenstein

Scientists are wondering if global warming and El Niño have an accomplice in fueling this summer’s record-shattering heat.

The European climate agency Copernicus reported that July was one-third of a degree Celsius (six-tenths of a degree Fahrenheit) hotter than the old record. That’s a bump in heat that is so recent and so big, especially in the oceans and even more so in the North Atlantic, that scientists are split on whether something else could be at work.

Scientists agree that by far the biggest cause of the recent extreme warming is climate change from the burning of coal, oil and natural gas that has triggered a long upward trend in temperatures. A natural El Niño, a temporary warming of parts of the Pacific that changes weather worldwide, adds a smaller boost. But some researchers say another factor must be present.

European Scientists Make it Official. July Was the Hottest Month on Record by Far

/in , , /by /The Associated Pressby Seth Borenstein

Now that July’s sizzling numbers are all in, the European climate monitoring organization made it official: July 2023 was Earth’s hottest month on record by a wide margin.

July’s global average temperature of 16.95 degrees Celsius (62.51 degrees Fahrenheit) was a third of a degree Celsius (six tenths of a degree Fahrenheit) higher than the previous record set in 2019, Copernicus Climate Change Service, a division of the European Union’s space program, announced Tuesday. Normally global temperature records are broken by hundredths or a tenth of a degree, so this margin is unusual.

“These records have dire consequences for both people and the planet exposed to ever more frequent and intense extreme events,” said Copernicus deputy director Samantha Burgess. There have been deadly heat waves in the Southwestern United States and Mexico, Europe and Asia. Scientific quick studies put the blame on human-caused climate change from the burning of coal, oil and natural gas.

Across the western U.S., many areas received record or near-record amounts of snowpack over the winter. With the spring and summer temperatures melting the abundant snow, a record volume of streamflow has been recorded in several basins in the southwestern U.S., providing more water for the area later into the summer than is typically seen.

Snowmelt Runoff Sets Streamflow Records in the Southwest

/in , /by

Across the western U.S., many areas received record or near-record amounts of snowpack over the winter. With the spring and summer temperatures melting the abundant snow, a record volume of streamflow has been recorded in several basins in the southwestern U.S., providing more water for the area later into the summer than is typically seen.

Snowmelt runoff in Walker and Carson basins

The Walker and Carson basins near the California-Nevada border, for example, have reported the largest volume of streamflow for April through July that has ever been observed in roughly a century, when the records began. The ample runoff is helping fill reservoirs that have been depleted from years of drought conditions.

Weekly U.S. Drought Monitor: Cooler Northwest, Warmer Southwest

Dry conditions dominated the West and southern Plains, coupled with above-normal temperatures. Precipitation was most widespread throughout much of the upper Midwest and central Plains and into the Northeast. Almost the entire country had near- to above-normal temperatures this last week, with the greatest departures over the Southwest and central Plains where temperatures were at least 4-7 degrees above normal.

Cooler-than-normal temperatures were recorded in the Pacific Northwest with departures of 3-6 degrees below normal. At the end of the current U.S. Drought Monitor period, significant rains developed over portions of the Midwest and central Plains, and they will be accounted for in the next analysis.

U.S. Seasonal Drought Outlook

Central portions of the Intermountain West may be spared degradation, as those areas are still showing residual benefits from above normal winter snowpack leading up to the summer, in addition to periods of above normal rainfall during the last 60 to 90 days. Seasonal temperature and precipitation outlooks, ENSO, and climatology favor widespread drought improvement and removal across the central U.S. However, drought persistence is favored across the Upper Midwest, although there is the potential for localized improvements.” Read full assessment: cpc.ncep.noaa.gov/products/expert_assessment/sdo_summary.php.

Seasonal Precipitation Outlook: November, December, January 2023-24

Colors show where total precipitation has an increased chance of being higher or lower than usual during the next three months. The darker the shading, the greater the chance for the indicated condition. White areas have equal chances for precipitation totals that are below, near, or above the long-term average (median) for the next three months.

Climate scientists base future climate outlooks on current patterns in the ocean and atmosphere. They examine projections from climate and weather models and consider recent trends. They also check historical records to see how much precipitation fell when patterns were similar in the past.

Copernicus Climate Change Service: July 2023 sees multiple global temperature records broken

July 2023 highlights:

  • The global average temperature for July 2023 is confirmed to be the highest on record for any month.
  • Antarctic sea ice extent continued to break records for the time of year, with a monthly value 15% below average, by far the lowest July extent since satellite observations began.
  • July 2023 was wetter than average over most of northern Europe and in a region from the Black Sea and Ukraine to northwestern Russia. Drier than average conditions were experienced across the Mediterranean basin, with Italy and southeastern Europe having the largest anomalies.
