Replication Data for "Dynamics and Couplings of Terrestrial Water Storage Extremes from GRACE and GRACE-FO Missions During 2002–2024"
No full textHydroclimatic extremes such as droughts and floods severely impact global livelihoods, economies, and ecosystems, yet their detection remains challenging. This study evaluates global Terrestrial Water Storage (TWS) extremeness and climate linkages using GRACE and GRACE-FO data from 2002 to 2024. By examining upper and lower deciles of TWS anomalies representing wet and dry extremes and assessing spatial dependencies, we identify key patterns, trends, and driving factors through dimensional reduction and probabilistic modeling. Results show global TWS extremes are governed by a 2–3-year oscillatory cycle linked to El Niño–Southern Oscillation, which synchronizes drought and pluvial conditions across continents. Drought extremes show broader spatial coherence than pluvial events, indicating moisture deficits propagate more uniformly through the land–atmosphere system. A weaker quasi-decadal cycle (6 to 10 years) modulates these responses and underlies a shift around 2011–2012: before 2011, wet extremes intensified, while after 2012, dry extremes became dominant, particularly in interior Asia, western United States, and southern Africa. Neither pluvial nor drought extremes show significant global trends in intensity; however, they remain phase-locked, with wet events twice as intense as dry ones, reflecting asymmetric hydrologic response to moisture surpluses versus deficits. We probabilistically reconstruct TWS extremeness during satellite data gaps using leading spatio-temporal patterns. The current record, spanning less than one multidecadal cycle, remains insufficient for robust attribution. Extending satellite gravimetry is essential to refine uncertainty in attributing global pluvial and drought extremes under climate change

Latin American Press Review, Program 1974-16, 1974 April 4
No full textPart I: The Latin American Press Review discusses Ecuador's oil revenue boom and its failure to alleviate economic issues, alongside warnings from Arturo Bonilla Sanchez about Latin America's worsening economic situation. Factors include rising import costs, declining exports, and the devaluation of the US dollar, exacerbated by multinational corporations' speculative activities. These challenges pose significant risks to the region's economy, particularly for developing nations like those in Latin America. Mexico grapples with soaring inflation, sparking social discord and clashes with the private sector, as government measures struggle to curb rising prices. Efforts to alleviate inflation include wage hikes and subsidized goods distribution, yet these initiatives raise concerns of unfair competition and perpetuate low-wage industries. President Luis Echeverría's critiques of the private sector strain relations further, but the government lacks the authority to effectively challenge private interests. The nation's economic woes are compounded by a trade deficit and heavy reliance on imports for industrial growth, exacerbated by increasing foreign investment. Despite these policies, a majority of Mexicans endure low living standards, widespread underemployment, and meager industrial wages, heightening Mexico's reliance on the United States and reinforcing the dominance of the private sector.

Latin American Press Review, Program 1973-25, 1973 September 6
No full textPart I: In Brazil, peasant guerrillas led by Osvaldão challenge the military near the Araguaia River, advocating for local demands such as land rights and fair prices. Despite military pressure, the guerrillas maintain popular support, prompting local oligarchs to propose violent solutions. In Argentina, after 17 years of military rule, the Peronist party returns to power with Juan Peron's candidacy, albeit with a shift towards centrism that disappoints leftist factions. Meanwhile, the Peronist Youth Group anticipates a radicalization of the movement. Additionally, allegations of CIA involvement surround Southern Air Transport, while Uruguay faces political unrest following a military takeover, and Colombia sees potential political shifts with Rojas Pinilla's nomination of his daughter as a presidential candidate. The Chilean government has responded to a six-week-old lockout by outlawing the Chilean Truck Owners Association, urging citizens to aid in transporting vital supplies amidst societal turmoil. Part II: Meanwhile, concerns about the world food situation have escalated due to weather-related crop failures and dwindling grain stocks, raising fears of long-term food scarcity and unequal distribution. Malnutrition remains a significant issue, particularly affecting millions in developing countries, with children bearing the brunt. The article reflects on shifting perceptions of the world food situation, from optimism fueled by the Green Revolution to present-day scrutiny of modern agricultural technology's impact on rural unemployment and food security. Despite projections of increased cereal production, challenges such as land scarcity and environmental constraints hinder efforts to boost agricultural productivity, underscoring the precarious nature of global food systems.

Replication Data for: Freshwater Availability in the Mississippi River Basin and Adjacent Texas Aquifers under Human and Climate Pressures
No full textWater security in the Mississippi River Basin and Texas aquifer region (MRBTX) faces pressure from irrigation demands, climate extremes, and climate change. We integrate groundwater observations, GRACE and GRACEFO total water storage anomalies (TWSA), drought data, climate projections, and irrigation-use analyses to assess aquifer sustainability across MRBTX. A longitudinal gradient exists; arid, irrigation-dependent western provinces show chronic storage deficits, while humid northern and eastern provinces are stable or recovering; a midcontinent transition belt shows minimal change. Groundwater level declines since 1950 average −16.66 ± 0.54 m in the central and southern High Plains and −15.20 ± 3.15 m in the Carrizo–Wilcox. GRACE data shows 85 ± 15 km³ removed from the central and southern High Plains and Texas aquifer since 2002. Gains occur in cooler regions, including 152 ± 57 in Great Lakes and northern Great Plains. The lower Mississippi and Gulf coast show non-significant storage of 32 ± 30 km³. West of 98° W within MRB-TX, droughts occur 1.3–2.0 times per decade lasting 13–15 months, with 2000–2020 irrigation withdrawals averaging 52 km³ yr⁻¹, mostly from groundwater. Climate change is highly to strengthen the east–west gradient under SSP2 4.5, with basin wide annual increases of about 5 to 15 percent driven by robust winter and spring gains in the humid east and north, and little change to slight summer drying in the arid west where model agreement is low. Nine aquifers in northern and eastern MRB–TX are projected sustainable by 2050. The central and southern High Plains and Carrizo–Wilcox are projected to decline −20.02 m and −20.84 m by 2050 at −2.99 and −3.34 m decade⁻¹. Limitations include satellite footprint, well coverage, and diagnostic uncertainties. Solutions include targeted pumping reductions, improved irrigation systems, conjunctive water use, and crop shifts in critical areas. Many provinces can remain secure with these measures; without them, two major aquifers face severe depletion

Does present-day Latin American art exist as a distinct expression?
No full textPart 1: Dr. Fred P. Ellison welcomes attendees to a symposium on Latin American art and literature, offering logistical instructions, introducing key figures and co-sponsors, and emphasizing the significance of cross-cultural dialogue through art. Dr. William Glade reflects on a museum visit that inspired thoughts on the interplay between the universal and regional in creative expression, setting the tone for the event’s discussions. The symposium, co-organized with Revista Plural, features an exhibition and curated panels meant to explore contemporary artistic and intellectual concerns in Latin America.
Part 2: The first session prepares to commence with introductions about the panelist's background and portfolios and remarks of gratitude towards the sponsors of the symposium. They explain the structure for the panel and proceed to begin the first session titled: "Does present-day Latin American art exist as a distinct expression?"
Part 3: The panelists engage in a dialogue about the challenges and opportunities facing Latin American artists in asserting their artistic independence and cultural heritage. The panelists navigate issues of identity, resistance, and autonomy in the context of a globalized art world, striving to articulate a vision of Latin American art that is both authentic and innovative.
Part 4: The panelists further the discussion about Latin American identity, with some suggesting that the question of whether or not there is a fixed identity is outdated, and that the focus should be on contemporary expressions and the role of artists in society. The perceived dependence on Latin American expression on European models is highlighted, though others emphasize the originality of work that older generations of Latin American artists have put out. Overall, it calls for a recognition of Latin American creativity as a model in its own right.
Part 5: The morning's session is wrapped up with closing remarks from Jaime Concha and Rufino Tamayo. Concha discusses the independent nature of Chile's artistic movements as it interacted with society and political activity. Rufino criticizes the overall concern to distinguish Latin American art as separate from art, arguing that all art is planetary, and that art draws from many elements, including Latin American. Finally, the sessions ends and after a pause, Rodolfo Cardona begins the afternoon session on Latin American literature
