<p>The sustainability of life on Earth is under increasing threat due to human-induced climate change. This perilous change in the Earth's caused by increases carbon dioxide and other greenhouse gases atmosphere, primarily emissions associated with burning fossil fuels. Over next two three decades, effects change, such as heatwaves, wildfires, droughts, storms, floods, are expected worsen, posing greater risks human health global stability. These trends call for implementation mitigation adaptation strategies. Pollution environmental degradation exacerbate existing problems make people nature more susceptible In this review, we examine current state from different perspectives. We summarize evidence Earth’s spheres, discuss emission pathways drivers analyze impact health. also explore strategies highlight key challenges reversing adapting change.</p>

Oceanic climate changes threaten the sustainability of Asia’s water tower

Nature, Journal Year: 2023, Volume and Issue: 615(7950), P. 87 - 93

Published: March 1, 2023

Water resources sustainability in High Mountain Asia (HMA) surrounding the Tibetan Plateau (TP)-known as Asia's water tower-has triggered widespread concerns because HMA protects millions of people against stress1,2. However, mechanisms behind heterogeneous trends observed terrestrial storage (TWS) over TP remain poorly understood. Here we use a Lagrangian particle dispersion model and satellite observations to attribute about 1 Gt monthly TWS decline southern during 2003-2016 westerlies-carried deficit precipitation minus evaporation (PME) from southeast North Atlantic. We further show that blocks propagation PME into central TP, causing increase by 0.5 Gt. Furthermore, warming-induced snow glacial melt well drying-induced depletion weaken blocking HMA's mountains, persistent northward expansion TP's since 2009. Future projections under two emissions scenarios verified 2020-2021 indicate that, end twenty-first century, up 84% (for scenario SSP245) 97% SSP585) could be afflicted deficits. Our findings trajectory towards unsustainable systems exacerbate downstream stress.

Global Increases in Lethal Compound Heat Stress: Hydrological Drought Hazards Under Climate Change

Geophysical Research Letters, Journal Year: 2022, Volume and Issue: 49(18)

Published: Sept. 20, 2022

Abstract Previous studies seldom consider humidity when examining heat‐related extremes, and none have explored the effects of on concurrent extremes high heat stress low river streamflow. Here, we present first global picture projected changes in compound lethal ( T h )‐drought hazards (CHD) across 11,637 catchments. Our observational datasets show that atmospheric conditions (e.g., energy vapor flux) play an important role constraining (32% ± 11%) yields a higher coincidence rate CHD than wet‐bulb temperature (28% 11%), driven by lower relative (RH) thus air dryness extremes. large model ensemble projects 10‐fold intensification bivariate risks 2071–2100, mainly increases Future declines RH, wind, snow, precipitation many regions are likely to exacerbate such water weather‐related drought CHD).

Published: July 30, 2024

Afghanistan, Central Asia. In this study, we evaluated the terrestrial water storage dynamics in Afghanistan and its five major river basins using anomalies (TWSA) from three Gravity Recovery Climate Experiment (GRACE) mascons observations JPL, CSR, GSFC processing centers, Famine Early Warning Systems Network (FEWS NET) Land Data Assimilation System – Asia (FLDAS-CA) simulation. Since 2008, due to intense prolonged drought conditions groundwater overexploitation, TWS has been decreasing at an alarming rate. The average slopes of TWSA trend for GRACE period (2003–2016) products range between − 3.6 4.8 mm/year. decrease is further exacerbated during GRACE-FO (2019–2022), ranging 20.4 30 Because heavily relied on country but human-induced change (i.e., extraction) not simulated FLDAS-CA, a significant difference could be observed FLDAS-CA results, especially following after each severe event (e.g., 2018) when substantial extraction occurred. assimilation into framework will undoubtedly have positive impact decision-makers local stakeholders preparing mitigating impacts overexploitation

Winter snow deficit was a harbinger of summer 2022 socio-hydrologic drought in the Po Basin, Italy

Communications Earth & Environment, Journal Year: 2024, Volume and Issue: 5(1)

Published: Feb. 3, 2024

Abstract Snow in mountainous regions is a key water resource from local to continental scales. However, the link between increasingly frequent snow droughts and socio-hydrologic impacts headwaters lowlands not fully understood. To untangle this relationship, here we combine climate reanalyses with range of data terrestrial storage, streamflow, emergency water-use restrictions for archetypal 2022 drought Po basin (Italy). We find that persistent high-pressure ridge during winter 2021–2022 translated into −88% anomaly peak equivalent, intraseasonal snowmelt, earlier melt-out dates. Compounded by reduced summer precipitation importantly increased temperatures, deficit led lowest storage on record 2022. Emergency were concurrent snowmelt early summer, rather than mid-winter. This study highlights contribution driving Basin.
