Colorado – Desdemona Despair

Map showing reduction of stored groundwater in the U.S. Southwest, April 2002 - September 2023. Gravity measurements from the GRACE series of satellites show that the decline in water levels in the Great Basin region from April 2002 to September 2023 has most severely affected portions of southern California (indicated in red). Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest.

NASA satellites find record snow didn’t offset Southwest U.S. groundwater loss – “In years like the 2022-23 winter, I expected that the record amount of snowfall would really help to replenish the groundwater supply. But overall, the decline continued.”

By James R. Riordon 17 June 2024 (NASA GSFC) – Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest, according to a new analysis of NASA satellite data [Snowfall Replenishes Groundwater Loss in the Great Basin of the Western United States, but […]

Change in percentage of U.S. kindergartners exempt from one or more vaccinations, by jurisdiction, 2021–22 and 2022–23 school years. From the 2019–20 to the 2021–22 school year, national coverage with state-required vaccines among kindergartners declined from 95 percent to approximately 93 percent, ranging from 92.7 percent for diphtheria, tetanus, and acellular pertussis vaccine (DTaP) to 93.1 percent for polio. During the 2022–23 school year, coverage remained near 93 percent for all reported vaccines, ranging from 92.7 percent for DTaP to 93.1 percent for measles, mumps, and rubella and polio. The exemption rate increased 0.4 percentage points to 3.0 percent. Exemptions increased in 41 states, exceeding 5 percent in 10 states. Exemptions >5 percent limit the level of achievable vaccination coverage, which increases the risk for outbreaks of vaccine-preventable diseases. Vaccination before school entry or during provisional enrollment periods could reduce exemptions resulting from barriers to vaccination during the COVID-19 pandemic.

School vaccination exemptions in U.S. now highest on record among kindergartners, CDC reports

By Sara Moniuszko 9 November 2023 (CBS News) – A record number of American kindergarten students started school last year with an exemption from one of the key vaccines health authorities require, according to new data from the Centers for Disease Control and Prevention. In the report published Thursday, the CDC examined immunization program data to […]

Extreme heat in North America, Europe, and China in July 2023 made much more likely by global warming – Without human-induced climate change these heat events would have been extremely rare: China heatwave would have been a 1 in 250-year event, and max heat like in July 2023 would have been virtually impossible in the U.S./Mexico region and Southern Europe

25 July 2023 (World Weather Attribution) – Following a record hot June, large areas of the US and Mexico, Southern Europe and China experienced extreme heat in July 2023, breaking many local high temperature records. July 2023 saw extreme heatwaves in several parts of the Northern Hemisphere, including the Southwest of the US and Mexico, […]

Americans are dying younger, and where you live makes a big difference – Americans born in Mississippi and Florida may die 20 years younger than their peers born in Colorado and California

By Jeremy Ney 12 April 2023 (TIME) – The average U.S. life expectancy has hit its worst decline in 100 years and America’s standing is dismal among peer nations. But the average obscures a more complex story. The United States is facing the greatest divide in life expectancy across regions in the last 40 years. Research from American […]

A wet winter won’t stave off the Colorado River’s water cuts – “There are discussions going on but they’re not making much progress. The level of distrust and animosity is really remarkable.”

By Joshua Partlow 3 April 2023 GRAND JUNCTION, Colorado (The Washington Post) – The abundant snow in the Rocky Mountains this year has been a welcome relief, but is not enough to overcome two decades of drought that has pushed major reservoirs along the Colorado River down to dangerous levels, Camille Calimlim Touton, the commissioner […]

Image of the Day: Satellite view of Lake Mead in 2000 and 2022 – “Declining water levels due to climate change and 20 years of ongoing drought have reshaped the park’s shorelines”

By Michael Carlowicz 20 July 2022 (NASA Earth Observatory) – Continuing a 22-year downward trend, water levels in Lake Mead stand at their lowest since April 1937, when the reservoir was still being filled for the first time. As of July 18, 2022, Lake Mead was filled to just 27 percent of capacity. The largest reservoir in the […]

Drought-stricken U.S. warned of looming “dead pool” – “It’s like watching this slow-motion catastrophe kind of unfold”

By Regan Morris and Sophie Long 4 June 2022 LOS ANGELES (BBC News) – A once-in-a-lifetime drought in the western part of the US is turning up dead bodies – but that’s the least of people’s worries. Sitting on the Arizona-Nevada border near Las Vegas, Lake Mead – formed by the creation of the Hoover […]

Drought has reduced the water level in Lake Mead so much that Southern Nevada Water Authority's original water intake valve in Lake Mead -- in service since 1971 -- was visible above the water line in April 2022. The original intake is no longer in use since it cannot draw water. Photo: Southern Nevada Water Authority

Lake Mead plummets to record low, exposing original 1971 water intake valve – Dead man found in barrel at lake bottom, authorities say more bodies likely to turn up – “This is a crisis. This is unprecedented.”

By Stephanie Elam 29 April 2022 (CNN) – The U.S. West is in the grips of a climate change-fueled megadrought, and Lake Mead — the largest manmade reservoir in the country and a source of water for millions of people — has fallen to an unprecedented low. The lake’s plummeting water level has exposed one of the reservoir’s original water […]
