Extremely high temperatures pose an immediate threat to humans and ecosystems. In recent years, many regions on land in the ocean experienced heat waves with devastating impacts that would have been highly unlikely without human-induced climate change. Impacts are particularly severe when occur exposure of people or crops. The 2018 spring-to-summer season was characterized by several major dry extremes. On daily average between May July about 22% populated agricultural areas north 30°...
Abstract Regional hot extremes are projected to increase more strongly than global mean temperature, with substantially larger changes 2°C even if warming is limited this level. We investigate the role of soil moisture‐temperature feedbacks for response based on multimodel experiments 21st century either interactive or fixed (late 20th seasonal cycle) moisture. analyze in hottest days each year both sets experiments, relate them temperature increase, and processes leading these changes. find...
Two extreme heatwaves hit Western Europe in the summer of 2019, with historical records broken by more than a degree many locations, and significant societal impacts, including excess mortality several thousand people. The extent to which human influence has played role occurrence these events been large interest scientists, media decision makers. However, outstanding nature poses challenges for physical statistical modeling. Using an unprecedented number climate model ensembles value...
Abstract. The frequency and intensity of climate extremes is expected to increase in many regions due anthropogenic change. In central Europe extreme temperatures are projected change more strongly than global mean temperatures, soil moisture–temperature feedbacks significantly contribute this regional amplification. Because their strong societal, ecological economic impacts, robust projections temperature needed. Unfortunately, current model projections, prone large uncertainties. order...
Abstract Concurrent extreme events, i.e. multi-variate extremes, can be associated with strong impacts. Hence, an understanding of how such events are changing in a warming climate is helpful to avoid some change impacts and better prepare for them. In this article, we analyse the projected occurrence hot, dry, wet events’ clusters multi-model ensemble 6th phase Coupled Model Intercomparison Project (CMIP6). Changes ‘extreme extremes’, only 1% probability current analysed, first as...
Abstract In 2018 and 2019, heatwaves set all‐time temperature records around the world caused adverse effects on human health, agriculture, natural ecosystems, infrastructure. Often, severe impacts relate to joint spatial temporal extent of heatwaves, but most research so far focuses either or attributes heatwaves. Furthermore, sensitivity characteristics choice heatwave thresholds in a warming climate are rarely discussed. Here, we analyze largest spatiotemporal moderate heatwaves—that is,...
This article investigates projected changes in temperature and water cycle extremes at 1.5°C of global warming, highlights the role land processes land-use (LUCs) for these projections. We provide new comparisons climate versus 2°C based on empirical sampling analyses transient simulations from ‘Half a degree Additional Prognosis Projected Impacts’ (HAPPI) multi-model experiment. The two approaches yield similar overall results regarding land, reveal substantial difference occurrence...
Extreme events, such as those caused by climate change, economic or geopolitical shocks, and pest disease epidemics, threaten global food security. The complexity of causation, well the myriad ways that an event, a sequence creates cascading systemic impacts, poses significant challenges to systems research policy alike. To identify priority security risks opportunities, we asked experts from range fields geographies describe key threats over next two decades suggest questions gaps on this...
Abstract. The Earth's land surface and the atmosphere are strongly interlinked through exchange of energy matter. This coupled behaviour causes various land–atmosphere feedbacks, an insufficient understanding these feedbacks contributes to uncertain global climate model projections. For example, a crucial role in exacerbating summer heat waves midlatitude regions has been identified empirically for high-impact waves, but individual models differ widely their respective representation...
Abstract The impacts of climate change are affecting human societies today. In parallel, socio-economic development has increased the capacity countries around global to adapt those although substantial challenges remain. Ongoing will continue result in a pressure adapt, while could make it easier do so. Countries’ effectiveness fostering resilience depend on pace both developments under different and emission pathways. Here we assess trajectories adaptation readiness comparison with...
Abstract Warm European summer temperatures are often preceded by low soil moisture conditions, but also depend on the atmospheric circulations and associated rainfall that may trigger drought to persist land‐atmosphere feedbacks take place. The quantitative role of early (ESSM) trends, versus trends in other large‐scale drivers (LS), explaining long‐term warming have not been investigated so far. Using regional climate simulations with forced circulation different possible initial moisture,...
There is strong evidence that the year 1540 was exceptionally dry and warm in Central Europe. Here we infer summer temperatures from number of days (NDDs) spring (March–May) (June–August) derived historical documentary published elsewhere, compare our estimates with present-day temperatures. We translate NDD values into temperature distributions using a linear relationship between modeled 3000 pre-industrial control simulation Community Earth System Model (CESM). Our results show medium...
The humanitarian community is actively working to mitigate the human impact of extreme weather and climate events. Social protection increasingly recognized as a promising mechanism address challenges posed by change, it supports individuals households in managing risks, thereby addressing drivers vulnerability, building resilience capacities contribute adaptation strategies (Costella & McCord, 2023).In this study, we focus on Ethiopia—a country grappling with compounded...

Abstract. Heat extremes have severe implications for human health, ecosystems, and the initiation of wildfires. While they are mostly introduced by atmospheric circulation patterns, intensity heat is modulated terrestrial evaporation associated with soil moisture availability. Thereby, ecosystems provide evaporative cooling through plant transpiration evaporation, which can be reduced under water stress. it has been shown that regional ecosystem limitation projected to increase in future,...

It is easy to recognize that Earth’s climate changing. Scientists agree the changes they observe are mostly caused by humans, primarily due greenhouse gases emitted burning of fossil fuels. Climate change has severe consequences—it leads glaciers melting; sea levels rising; increased numbers dangerous heatwaves, wildfires and droughts; decrease yields from food crops; loss ecosystems. We can monitor in tracking global average temperature. In this article, we will introduce concept discuss...
The humanitarian community has a long history of attempting to reduce the human impact extreme weather and climate events. Over past decade there been an increasing shift in towards using science better anticipate impacts on vulnerable communities hence guide planning responses. However, large uncertainties, non-climate, complex compounding risks pose significant challenges integrating information into planning.
