Abstract Wildfire activity is expected to increase across the Mediterranean Basin because of climate change. However, effects future change on combinations atmospheric conditions that promote wildfire remain largely unknown. Using a fire-weather based classification wildfires, we show scenarios point an in frequency two heat-induced types have been related largest wildfires recent years. Heat-induced are characterized by compound dry and warm occurring during summer heatwaves, either under...
Abstract The year 2020 had the most catastrophic fire season over last two decades in Pantanal, which led to outstanding environmental impacts. Indeed, much of Pantanal has been affected by severe dry conditions since 2019, with evidence 2020’s drought being extreme and widespread ever recorded 70 years. Although it is unquestionable that this mega-drought contributed significantly increase risk, so far, analyzed at univariate level a single climate event, not considering co-occurrence...
An increase in the frequency of extremely hot and dry events has been experienced over past few decades South America, particularly Brazil. Regional climate change projections indicate a future aggravation this trend. However, comprehensive characterization drought heatwave compound events, as well main land–atmosphere mechanisms involved, is still lacking for most America. This study aims to fill gap, assessing first time historical evolution summer heavily populated region Southeast Brazil...
Abstract. Drought and heat events in Europe are becoming increasingly frequent due to human-induced climate change, impacting both human well-being ecosystem functioning. The intensity effects of these vary across the continent, making it crucial for decision-makers understand spatial variability drought impacts. Data on drought-related damage currently dispersed scientific publications, government reports, media outlets. This study consolidates data European forests from 2018 2022, using...
<strong class="journal-contentHeaderColor">Abstract.</strong> The interaction between co-occurring drought and hot conditions is often particularly damaging to crop's health may cause crop failure. Climate change exacerbates such risks due an increase in the intensity frequency of dry events many land regions. Hence, here we model trivariate dependence spring maximum temperature precipitation wheat barley yields over two province regions Spain with nested copulas. Based on full joint...
In the last years a large number of weather driven extreme events has occurred worldwide with unprecedented socio-economic impacts and are expected to increase, in both frequency intensity, under future global-warming conditions. this context early identification predictability such paramount as they mostly affect several activities. Despite effort monitoring evaluation these events, quantitative assessment their interaction is still challenge. We propose analyze if occurrence extremely hot...
The Iberian Peninsula (IP) is a drought-prone area located in the Mediterranean which presents significant tendency towards dryness during last decades, reinforcing need for continuous monitoring of drought. long-term evolution drought IP analyzed, using Standardized Precipitation Evaporation Index (SPEI) and (SPI), period 1901–2012 three subperiods: 1901–1937, 1938–1974, 1975–2012. SPI SPEI were calculated with 12-month time scale, data from Climatic Research Unit (CRU) database. Trends...
Portugal is regularly affected by destructive wildfires that have severe social, economic, and ecological impacts. The total burnt area in 2017 (∼540,000 ha) marked the all-time record value since 1980 with a tragic toll of 114 fatalities occurred June October events. local insurance sector declared it was costliest natural disaster payouts exceeding USD295 million. Here, event, responsible for more than 200,000 ha 50 analyzed from compound perspective. A prolonged drought led to...
Abstract Changes in the frequency and magnitude of dry spells have been recorded over past few decades due to an intensification global water cycle. A long-term soil drying trend resulting from a joint contribution natural decadal variability precipitation levels increasing temperatures, predisposed central-east South America (CESA) experience during 2019–2022 period outstanding desiccation. Flash droughts led large areas (~100.000 $${{km}}^{2}$$ <mml:math...
Population exposure to heat waves (HWs) is increasing worldwide due climate change, significantly affecting society, including public health. Despite its significant vulnerabilities and limited adaptation resources rising temperatures, South America, particularly Brazil, lacks research on the health impacts of temperature extremes, especially role played by socioeconomic factors in risk heat-related illness. Here, we present a comprehensive analysis effects HWs mortality rates 14 most...
Each wildfire has its own “history”, burns under specific conditions and leads to unique environmental impacts. Information on where when it started duration is important improve understanding the dynamics of individual wildfires. This information typically included in fire databases that are known have: (i) multiple error sources; (ii) limited spatial coverage and/or time span, and; (iii) often unknown accuracy uncertainty. Satellite data have a large potential reduce such limitations. We...
We present a simple neural network and data pre–selection framework, discriminating the most essential input for accurately forecasting concentrations of PM10, based on observations years between 2002 2006 in metropolitan region Lisbon, Portugal. Starting from broad panoply different sets collected at several air quality meteorological stations, forward stepwise regression procedure is applied enabling to automatically identify important variables predicting pollutant also rank them order...
The first week of December 1876 was marked by extreme weather conditions that affected the south-western sector Iberian Peninsula, leading to an all-time record flow in two large international rivers. As a direct consequence, several Portuguese and Spanish towns villages located banks both rivers suffered serious flood damage on 7 1876. These unusual floods were amplified preceding particularly autumn wet months, with October presenting extremely high precipitation anomalies for all western...
Droughts and hot extremes are major sources of risk to several socio-economic activities their impacts expected increase under future global warming. Moreover, the simultaneous or sequential occurrence (compound events) different climate may lead amplification associated impacts. Even though latest efforts in assessing dry interactions, development models describing joint behavior is still a challenge. To contribute understanding these compound events, we propose assess probability extremely...
Abstract The impact of climate change on wheat and barley yields in two regions the Iberian Peninsula is here examined. Regression models are developed by using EURO-CORDEX regional model (RCM) simulations, forced ERA-Interim, with monthly maximum minimum air temperatures accumulated precipitation as predictors. Additionally, RCM simulations different global for historical period (1972–2000) mid-of-century (2042–2070; under emission scenarios RCP4.5 RCP8.5) analysed. Results point to...
