Implications pour la disponibilité de l'eau douce
À l'heure actuelle, le #pompage excessif des eaux souterraines est le principal facteur contribuant aux taux de déclin en #stockage de l'eau terrestre dans les régions en voie d'assèchement, amplifiant de manière significative les impacts de l'augmentation de la #température, de l'#aridification et des épisodes de #sécheresse extrême. La #surexploitation continue des eaux souterraines qui, dans certaines régions comme la #Californie, se produit à un rythme croissant, plutôt qu'à un rythme durable ou décroissant, compromet la sécurité régionale et mondiale de l'eau et de l'alimentation d'une manière qui n'est pas pleinement reconnue dans le monde entier.
L'épuisement des eaux souterraines est directement affecté par les décisions de gestion de l'eau et peut également être stoppé par celles-ci.
Dans de nombreux endroits où les eaux souterraines s'épuisent, elles ne se reconstitueront pas à l'échelle humaine. La disparition des eaux souterraines des #aquifères de la planète constitue une nouvelle #menace grave pour l'humanité et présente des #risques en cascade qui sont rarement pris en compte dans les #politiquesenvironnementales, la #gestion et la #gouvernance.

Southwestern #drought likely to continue through 2100, research finds
Southwestern #US is experiencing a #megadrought resulting in the #aridification of the landscape, a decades-long drying of the region brought on by climate change and the overconsumption of the region’s #water.
Using an ensemble of historical and future #climate models forecasting climate and precipitation patterns until 2100, they found that the PDO-like negative phase continues through this century.

"ancient #aridification – an increase in dryness seen in several American regions – cannot fully explain cactus #evolution.

"Research carried out by the Cuban Government suggest that Cuba’s climate is evolving from a humid tropical country to a dry tropical country, with average temperatures of over 30°C, approximately 1000 mm of rainfall on average per year and 70 rainy days. These conditions will lead to migration from dry areas in the eastern region to other parts of the country."

Press Release from the Center For Biological Diversity
For Immediate Release, May 10, 2023
#NewMexico Sued Over Failure to Control Skyrocketing #Oil, #Gas #Pollution
Landmark Lawsuit Targets State’s Constitutional Duty
SANTA FE, N.M.— "A coalition of #IndigenousPeoples, #youth, frontline community members and #environmental groups sued New Mexico, the state legislature, Gov. Michelle Lujan Grisham and state agencies today for violating their state constitutional duty to control the rapidly growing pollution from the #OilAndGas industry.
"The first-of-its-kind lawsuit seeks compliance with the pollution control clause of the New Mexico Constitution under Article 20, Section 21. No previous lawsuit has targeted the 1971 amendment, which mandates that the state prevent the despoilment of New Mexico’s air, water and other natural resources, and protect the state’s beautiful and healthful environment.
"Oil production in New Mexico’s #PermianBasin, one of the largest oilfields in the world, has increased nearly 10-fold since 2010, leading to a surge of devastating air, water and #climate pollution.
"Today’s lawsuit demands that the state comply with its constitutional duty to protect New Mexico’s environment, and that permitting of oil and gas wells be suspended in the meantime.
"'New Mexico’s failure to control oil and gas pollution violates our constitution and fundamental human rights to clean air, land and water,' said Gail Evans, an attorney at the Center for Biological Diversity’s Climate Law Institute and lead counsel on the case. 'If concern for our environment and public health won’t push New Mexico’s leaders to control the reckless oil and gas industry, we hope legal action will.'
"Air quality in several of the state’s oil- and gas-producing counties fails to meet federal standards established to protect public health. Eddy and San Juan Counties received an 'F' from the American Lung Association for high ozone days, and Lea and Sandoval Counties got a 'D.'
"Indigenous, youth and frontline communities are disproportionately harmed by the state’s failure to control oil and gas pollution. Plaintiffs in the case are additionally seeking relief under the constitution’s equal protection and fundamental rights clauses.
"'New Mexico has allowed sacred #Diné lands in the Eastern #Navajo Agency to be completely ravaged by oil and gas extraction and pollution,' said Mario Atencio, a plaintiff in the case from #Torreon / #Starlake Chapter of the #NavajoNation. 'There is zero accountability for the dangerous #AirPollution that my community breathes and the #ToxicSpills that pollute our precious lands and waters.'
"Oil and gas operators spill toxic liquid waste an average of four times per day in New Mexico, endangering land, air, water and public health.
Meanwhile, as the state faces increasing #aridification from #ClimateChange, oil companies use vast quantities of New Mexico’s dwindling #freshwater resources for #fracking. In 2019 the industry used approximately 14 billion gallons of New Mexico's fresh water resources — equivalent to household use for more than 278,000 people."'#Extractive industry is desecrating our #ancestral homelands and imposing irreparable harm to our water, #plant and #animal relatives,' said Julia Bernal, executive director of Pueblo Action Alliance. 'It’s unacceptable that New Mexico is continuing the legacy of harm and pollution through our communities by its racist and inequitable policies.'
"This constitutional lawsuit has far-reaching implications. As the second-largest oil-producing state in the country and one of the leading gas producers, New Mexico is responsible for over 50% more greenhouse gas emissions than the national average. Pollution from New Mexico’s oil and gas industry plays a colossal role in the climate crisis, threatening plaintiffs’ right to a livable future.
“'I’m terrified to think of my generation’s climate future when I’ve already seen triple-digit heat records and the biggest wildfire in New Mexico’s history last summer,' said 21-year-old Zephyr Jaramillo with Youth United for Climate Crisis Action. 'As one of the largest oilfields in the world, the Permian Basin threatens to pollute my future into oblivion. New Mexico needs to change course and rein in oil and gas pollution to give all of us a chance at a healthy future.'
"The case was filed today in the First Judicial District Court of New Mexico by #IndigenousLifeways, #PuebloActionAlliance, Youth United for Climate Crisis Action, Center for Biological Diversity, WildEarth Guardians and individuals living on the frontlines of oil and gas extraction."

Colorado River losing vast amounts of water due to warming climate, study finds
Roughly half the decline in the river’s flow has been caused by higher temperatures
#Climate #change is driving the #aridification of the Southwest. In multiple studies, researchers have estimated that by mid-century, the river’s #average #flow could decline by 30% or more below the average of the past century.
Already, the river’s flow has shrunk about 20% since 2000 during a megadrought that scientists have described as the driest 22-year period in the American West in at least 1,200 years
