Abstract Compound hot and dry events (CHDEs) pose an increasing threat to global warming have received growing attention in recent decades. We conducted a detection attribution analysis (D&A) using the optimal fingerprint technique analyze changes observed CHDEs at continental sub‐continental scales from 1961 2014. The responses of anthropogenic (ANT), greenhouse gases (GHG), aerosols (AER), natural (NAT) forcings were obtained Coupled Model Intercomparison Project phase 6 forcing experiment. In two‐signal D&A that considered ANT NAT simultaneously, signals robustly detected separated all domains more than 65% subcontinental (29 out 44 domains). trend attributed is comparable over where signal detectable. also three‐signal regressed observation onto GHG, AER, simultaneously. GHG detectable continents except Oceania, it contributed dominantly 22 29 regions had emerged. Multivariate biases correction can largely reduce models' simulating marginal distribution dependence structure, which provide accurate future risk CDHEs. found limiting 1.5℃ rather 2.0℃ significantly mitigate impact compound most areas land, particularly South America, Africa, Oceania.

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.

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.

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.

Owing to amplified impacts on human society and ecosystems, compound events (or extremes) have attracted ample attention in recent decades. China is particularly vulnerable due the fast warming rate, dense populations, fragile ecological environment. Recent studies demonstrated tangible effects of climate change with mounting economy, agriculture, public health, infrastructure China, posing unprecedented threats that are increasingly difficult manage. Here, I synthesize progress associated China. Several lines evidence indicate an increase frequency intensity multiple types across Future directions studying suggested, including investigating extremes from a perspective, modeling Anthropocene, quantitative evaluations risks, holistic adaptation measures events.

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

Attribution studies recent have formed a new important line evidence in most Intergovernmental Panel on Climate Change (IPCC) assessment report present-day IPCC using different methods event been assessed together, highlighting that these differences are smaller than academic discourse suggests. This development raised two research questions science needs answer: First, how do we formally combine statements highly conditional probabilistic assessments change alters likelihood intensity events?

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.
