Published: Oct. 25, 2021

Abstract Compound weather and climate events are combinations of drivers and/or hazards that contribute to societal or environmental risk. Studying compound often requires a multidisciplinary approach combining domain knowledge the underlying processes with, for example, statistical methods model outputs. Recently, aid development research on events, four event types were introduced, namely (a) preconditioned , (b) multivariate (c) temporally compounding (d) spatially events. However, guidelines how study these still lacking. Here, we consider case studies, each associated with specific type question, illustrate key elements (e.g., analytical tools relevant physical effects) can be identified. These studies show impacts crops from hot dry summers exacerbated by preconditioning effects bright springs.

Societally relevant weather impacts typically result from compound events, which are rare combinations of and climate drivers. Focussing on four event types arising different variables across space time, here we illustrate that robust analyses events - such as frequency uncertainty analysis under present-day future conditions, attribution to change, exploration low-probability-high-impact require data with very large sample size. In particular, the required is much larger than needed for univariate extremes. We demonstrate Single Model Initial-condition Large Ensemble (SMILE) simulations multiple models, provide hundreds thousands years crucial advancing our assessments constructing model projections. Combining SMILEs an improved physical understanding will ultimately practitioners stakeholders best available information risks.

A comprehensive review on the recycling technology of silicon based photovoltaic solar panels: Challenges and future outlook

Journal of Cleaner Production, Journal Year: 2024, Volume and Issue: 448, P. 141661 - 141661

Published: March 8, 2024

With the aim of realizing goals Paris Agreement, annual solar power generation on a global scale using silicon PV panels had exceeded 1000 TWh by end 2021. Mass installation silicon-based photovoltaic (PV) exhibited socioenvironmental threat to biosphere, i.e., electronic waste (e-waste) from that is projected reach 78 million tonnes year 2050. Recycling through e-waste management crucial step in minimizing environmental impact end-of-life systems such as release heavy metals into environment. An increasing amount academic research recycling approaches suggests different technology and policy challenges remain. The present review critically evaluates range solutions, encompassing both lab-scale pilot-scale research, conducts analyses their cost implications. A detailed discussion policies adopted governments worldwide handle has also been provided. In this article, complete process systematically summarized two main sections: disassembly delamination treatment for panels, involving physical, thermal, chemical treatment, retrieval valuable (silicon, silver, copper, tin, etc.). Furthermore, technical, non-technical prospects are identified guide future exploration innovation. pursuit sustainable convenience, cost-effectiveness, social desirability should come together develop innovative technologies with high recovery rate metals.

Origin, importance, and predictive limits of internal climate variability

Environmental Research Climate, Journal Year: 2023, Volume and Issue: 2(2), P. 023001 - 023001

Published: April 21, 2023

Abstract Adaptation to climate change has now become a necessity for many regions. Yet, adaptation planning at regional scales over the next few decades is challenging given contingencies originating from combination of different sources projection uncertainty, chief among them internal variability. Here, we review causes and consequences variability, how it can be quantified accounted in uncertainty assessments, what research questions remain most pertinent better understand its predictive limits science society. This perspective argues putting variability into spotlight intensifying collaborations between modeling application communities.

Consideration of compound drivers and impacts are often missing from applications within the Disaster Risk Reduction (DRR) cycle, leading to poorer understanding risk benefits actions. The need include considerations is known, but lack guidance prohibiting practitioners including these considerations. This article makes a step toward practitioner by providing examples where consideration drivers, hazards, may affect different application domains disaster management. We discern five DRR categories provide illustrative studies that highlight role "compound thinking" in early warning, emergency response, infrastructure management, long-term planning, capacity building. conclude with number common elements contribute development practical guidelines develop appropriate for

Abstract Compared with individual extreme events, compound events have more severe impacts on humans and the natural environment. This study explores change in severity of high temperature drought/rain (CHTDE/CHTRE) associated influencing factors. The CHTDE CHTRE intensified most areas China summer (June–July August) during 1961–2014. Under global warming, increased water-holding capacity atmosphere decreased relative humidity led to an increase CHTDE. is because enhanced transient water vapor convergence convective motion. Anthropogenic climate change, especially greenhouse gas forcing, which contributes 90% linear CHTRE, identified as dominant factor affecting China. In addition, historical forcing (hist-NAT) may be related interannual-to-decadal variability CHTDE/CHTRE.
