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.

Snowmelt Runoff Sets Streamflow Records in the Southwest

/in , , /by /Water News Network

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.

We’re living in a pivotal moment in history, on the cusp of either sinking into a dark period of growing poverty, accelerating ecological destruction, and worsening conflict, or moving forward to a new age of equity, sustainability, and stewardship of the only planet in the universe where we know life exists. I believe a positive future is not only possible, but inevitable, but solving our current crises and moving along the path to that desired future will require new, concerted, and sustained efforts.

Her Bedroom Was 100 Degrees During Phoenix Heat Wave — and Her AC Was Out

/in , , /by /Los Angeles Timesby Jack Herrera

It was just before dinnertime on Day 16 of the worst heat wave in Phoenix history, and the temperature outside Karen Shute’s suburban home was 117 degrees.

Inside, Shute mixed two cocktails and sat down with her friend at the kitchen table. To save on her electric bill, Shute kept her thermostat around 80 degrees during the summer, but she decided she’d treat her friend that evening. She got up and turned it down to 77.

Lush Landscape Recognized as Runner-Up in Helix Landscape Contest

The slope of a 1920s La Mesa home went from a drab lawn to lush floral color with climate-appropriate plants, winning recognition from the Helix Water District as the runner-up in its 2023 WaterSmart Landscape Contest.

The contest promotes beautiful, water-efficient landscapes and rewards people for their inspiring gardens. Joanna and Larry Henning created the country garden with climate-appropriate plants.

The Hennings bought the property in La Mesa‘s historic downtown area in 2017. Its landscape was covered in weeds and poorly maintained trees. The couple wanted a new landscape that would fill in the expansive slope and be water efficient while staying true to the character of their home.

Succulent cuttings

Planting an area this large with new plants can be expensive. But the couple were creative and resourceful, sourcing their plants for the new landscape design. Larry Henning used succulent cuttings from friends and family to plant most of their new landscape.

They supplemented the landscape with carefully chosen specimen plants, including protea, sages, and plumeria. These choices create the landscape’s variety of interesting shapes and colors. Five years after starting the project, even the slowest growing plants are fully grown and have transformed the landscape.

Irrigation efficiency

The landscape uses water efficiently to provide enough water for the plants to flourish without waste. Watering schedules are controlled using a smart weather-based irrigation controller. It automatically adjusts for rain and weather changes. Plants receive water from inline drip irrigation with pressure-compensating drip emitters.

Pressure compensation is essential for sloped landscapes because it maintains even watering rates all along the slope and prevents overwatering areas at the bottom of the landscape, where pressure is higher. Mulch covers the drip system, which protects the soil and slows evaporation.

The landscape delivers ample curb appeal. From the street, trees frame the landscape, filled with shades of green and pops of color. Viewers can also see agave, cacti, and dozens of other succulents. Many display long cones of flowers. From the front patios, the garden provides a tranquil space for the family to enjoy.

District officials selected the landscape for special runner-up recognition due to its impressive transformation and efficient use of color and irrigation.

Helix Water District holds its landscape makeover contest annually. Entries are accepted starting every February through mid-May. For entry information, go to landscapecontest.com.
