Опубликована: Фев. 9, 2023

In late June 2021 a heatwave of unprecedented magnitude impacted the Pacific Northwest region Canada and United States. Many locations broke all-time maximum temperature records by more than 5 °C, Canadian national record was broken 4.6 with new 49.6 °C. Here, we provide comprehensive summary this event its impacts. Upstream diabatic heating played key role in anomaly. Weather forecasts provided advanced notice event, while sub-seasonal showed an increased likelihood heat extreme lead times 10-20 days. The impacts were catastrophic, including hundreds attributable deaths across Northwest, mass-mortalities marine life, reduced crop fruit yields, river flooding from rapid snow glacier melt, substantial increase wildfires-the latter contributing to landslides months following. These examples can learn vivid depiction how climate change be so devastating.

Different mechanisms for the extremely hot central-eastern China in July–August 2022 from a Eurasian large-scale circulation perspective

Abstract In July and August of 2022, unprecedented long-lasting heatwaves attacked central eastern China (CEC); the most affected area was in Yangtze River (YR) basin. The extreme associated drought wildfire had significant social impacts, but underlying mechanisms remain unknown. Observational analysis indicates that were regulated by anomalous anticyclone mid-upper troposphere over northern CEC. Specifically, easterly anomalies at southern flank caused air isentropic sliding transported low moist enthalpy (cold dry) to YR basin, contributing sinking motions heatwaves. comparison, more serious than due stronger upper-level easterlies. Importantly, different responsible for two months. July, relatively weaker anticyclonic anomaly CEC dominated forcing diabatic heating northwestern South Asia (NWSA), corresponding with record-breaking rainfall around Pakistan. August, a powerful condition originated from an silk road pattern (SRP), superposing effect NWSA persistent downpour. We notice another upstream node SRP also created Europe. Therefore, heat actually other concurrent extremes Eurasian continent through large-scale atmospheric teleconnections 2022.

Fibrous MXene Aerogels with Tunable Pore Structures for High-Efficiency Desalination of Contaminated Seawater

Nano-Micro Letters, Год журнала: 2023, Номер 15(1)

Опубликована: Март 21, 2023

Abstract The seawater desalination based on solar-driven interfacial evaporation has emerged as a promising technique to alleviate the global crisis freshwater shortage. However, achieving high performance actual, oil-contaminated remains critical challenge, because transport channels and interfaces of current solar evaporators are easily blocked by oil slicks, resulting in undermined rate conversion efficiency. Herein, we propose facile strategy for fabricating modularized evaporator flexible MXene aerogels with arbitrarily tunable, highly ordered cellular/lamellar pore structures high-efficiency interception desalination. core design is creation 1D fibrous MXenes sufficiently large aspect ratios, whose superior flexibility plentiful link forms lay basis controllable 3D assembly into more complicated structures. cellular structure responsible effective contaminants rejection due multi-sieving effect achieved omnipresent, isotropic wall apertures together underwater superhydrophobicity, while lamellar favorable rapid presence continuous, large-area channels. delivers best (1.48 kg m −2 h −1 ) efficiency (92.08%) among all MXene-based materials seawater."Image missing"

Agricultural land measures for climate change adaptation in arid regions: Can the farmers do it alone?

Journal of Aridland Agriculture, Год журнала: 2024, Номер unknown, С. 82 - 93

Опубликована: Июнь 28, 2024

Climate change has become an unequivocal issue; changing precipitation patterns and climate variability will have disastrous impacts on the fragile agricultural land resources of arid regions. Farmers, equipped with indigenous knowledge readily available resources, are most direct stakeholder interacting lands; examining farmers’ capacity to successfully implement farm-level adaptive measures is a pressing matter. This paper provides overview various for adaptation in regions discusses some major relevant constrains extent capabilities such strategies. Various techniques as shifting sowing dates, conservation agriculture, rainwater harvesting shown potential serve These can help reduce crop failure risks, improve soil moisture increase water availability crops, could adapt However there strong evidence that many farmers may not be able strategies no clear currently less risk existence measures. attributed constraints need reliable access climatic data, research output by successful implementation. circumvented institutional-level subsidies, dynamic policies, programs. Overwhelming suggests this only possible involvement stakeholders planning process researchers, private sector.

South European Heatwaves and Their Impacts on the Power System in 2022

Journal of Geophysical Research Atmospheres, Год журнала: 2025, Номер 130(3)

Abstract Unprecedented heatwaves accompanying severe droughts hit South Europe in May‒July 2022. From the interdisciplinary perspective, this study revealed that extreme climate events can intensify European energy crisis through pushing up electricity demand and limiting renewable supply makes more than one‐third of gross consumption Union (EU). The record‐high over was closely associated with long‐lasting heatwaves. On other hand, anomalous high‐pressure system contributed to shortage power generation, for instance, affecting wind speed. generation reduced by anticyclone which weakened low‐tropospheric prevailing northwesterly wind. results indicate a potential intensive conflict between increasing decreasing are induced simultaneously Therefore, it is suggested sectors' resilience should be well built as EU sets significantly increase target meet goal climate‐neutral 2050.
