This review summarizes the intricate relationship between climate change and forest ecosystems in the Northwest Iberian Peninsula, outlining both their resilience and vulnerabilities. The study asserts the significant impact of climate change on these ecosystems, reinforcing earlier theories about their responsive behavior to global climatic alterations. However, the impacts are highly localized, contingent upon specific forest compositions, topography, and interaction with other environmental stressors. The temperate forests of the Northwest Iberian Peninsula manifest a delicate balance of resilience and vulnerability in the face of these phenomena. Notably, the study underscores that this region’s forest ecosystems remain a relatively uncharted research territory, promising fruitful prospects for future exploration. Although existing studies offer vital insights into the climate change impacts, there is a stark need for further research to gain a deeper understanding of, and formulate appropriate responses to, the challenges that these specific ecosystems confront in the wake of climate change.

As the global climate is changing dramatically, the Westfjords of Iceland are facing a multitude of challenges, including changing weather patterns, sea level rise, and invasive species. In order to cope with the recent climatic changes—many of which present great uncertainties to livelihoods—strategies must be developed to plan and adapt for the future. Iceland has recently launched marine spatial planning (MSP) endeavours, and one of the first planning processes has been conducted in the Westfjords. MSP presents opportunities for authorities, stakeholders, and the public to come together to forge a sustainable path ahead for marine areas that are under increasing pressure from human activities. However, MSP comes with its own considerable challenges as it attempts to engage stakeholders and the general public in decisions about an ‘invisible’ space largely beneath the surface of the sea. In this paper, the uncertainties of the environmental changes will be explored in conjunction with the multitude of societal challenges to coastal and marine planning in the Westfjords to establish Iceland’s unique context for MSP and to make recommendations for its development. Data from the planning documents as well as from semi-structured interviews and a workshop conducted in the Westfjords will be analysed and discussed. The results show both an urgent environmental need to take action to adapt to ongoing climate change effects and a complex societal structure that favours those who already have power and influence over others. Our recommendations include reforming the Icelandic MSP process with a view to strengthening the public participatory channels as well as the transparency, trust, and accessibility of the process.

The adverse and severe impacts of climate-induced natural hazards, which are expected to be aggravated by climate change, are forming a wider outline of the environmental crisis, being a source of negative emotions for human societies. Children and young people, in particular, are one of the most vulnerable social groups to this distress. In this research, we intend to analyze the eco-anxiety and climate anxiety aspects of Generation Z, based on a critical review of studies on children’s and young people’s ecological feelings worldwide, alongside a study of actual data on natural disasters per country since the year 2000. The results of the research revealed that (a) Generation Z worries in the Global North and suffers in the Global South, (b) Generation Z acts against climate change, and (c) there is an existential dimension of children’s and young people’s eco-anxiety. The study also highlights dimensions of eco-anxiety that are under-researched and are important to explore in the future. Empathizing with Generation Z’s emotional state in relation to ecological crisis and climate change may affect and highlight new directions in environmental thought and awareness. Full article

The transport sector is the second leading emitter of greenhouse gas emissions (GHGEs) from fuel combustion activities on a global scale. Reducing emissions related to this sector requires detailed data about the emissions by vehicle type and traveled distance. Generally, these data are missing in developing countries, which makes difficult the establishment of effective policies for the reduction of these emissions. This paper presents a hybrid method to estimate these emissions using the IPCC 2006 guidelines. The method combines bottom-up and top-down approaches to estimate vehicular emissions using data about the vehicle type, vehicle kilometers traveled, and fuel consumption. This method is applied for the first time for the Palestinian territory. Data have been collected from the administration, official reports, and papers. The results show a significant increase in the total vehicles in Palestine, particularly diesel vehicles. Emissions from the on-road transport system were approximately 2,207,834 tons of CO₂eq in 2019. Diesel vehicles were responsible for about 75% of these emissions. Private cars were the most significant contributor to these emissions, with a share exceeding 50% of the total emissions, followed by commercial vehicles and light trucks (20%), public taxis (9%), and buses (7%). These results show clearly that the GHGEs reduction policies in Palestine should focus on diesel and private vehicles by developing the public transport systems and replacing diesel and gasoline vehicles with more environmentally friendly vehicles, such as hybrid and electric cars.

New environmental extremes are currently underway and are much greater than those in previous records. These are mostly regional, singular events that are caused by global change/local weather combinations and are larger than the impact of linear temperature increases projected using climate models. These new states cannot easily be assigned probabilities because they often have no historical analogs. Thus, the term super climate extremes is used. Examples are the loss of sea ice and ecosystem reorganization in northern marine Alaska, heatwave extreme in western Canada, and the loss of snow in Greenland. New combined extreme occurrences, which are reported almost daily, lead to a new, higher level of climate change urgency. The loss of sea ice in 2018–2019 was a result of warmer Arctic temperatures and changes in the jet stream. They resulted in a chain of impacts from southerly winds, the northward movement of predatory fish, and the reduction of food security for coastal communities. Record temperatures were measured in southwestern British Columbia following previous drought conditions, a confluence of two storm tracks, and warming through atmospheric subsidence. Greenland’s losses had clear skies and jet stream events. Such new extremes are present indicators of climate change. Their impacts result from the interaction between physical and ecological processes, and they justify the creation of a new climate change category based on super climate extremes. Full article

According to data obtained from meteorological towers, Brazil has significantly increased temperature in the past 20 years, particularly in the North and Midwest regions. Vapor pressure deficit and evapotranspiration were also analyzed, showing an increase across the entire country, confirming that the air is becoming drier. This warming trend is part of the global climate change phenomenon caused by the rise of greenhouse gases in the atmosphere, fires, poor soil management practices, deforestation, and logging. The increase in temperature and dryness has profoundly impacted Brazil’s climate and ecosystems, leading to intensified extreme weather events and changes in the distribution of both animal and plant species. This study highlights the importance of utilizing meteorological tower data to monitor and understand the effects of climate change in Brazil. It emphasizes the need for immediate action to address its causes and mitigate its negative impacts. Full article

A prevalent engineering task in practice is calculating the annual balance of sediments on some watercourses. This is particularly challenging when assessing the backfilling of river reservoirs that have a multifunctional purpose. Trakošćan Lake was built in the period from 1850 to 1862 as a pond and landscape addition to the park and Trakošćan castle. After 60 years, the lake was drained in 2022, and the work began on sediment excavation to improve the lake’s ecological condition due to about 200,000 cubic meters of deposited silt in the lake. In this research, the annual sediment production is calculated for the long-term period 1961–2020, based on empirical parametric methods (Fleming, Brunne). The results are compared with results from previous projects and recent sediment deposit investigations. Since there are no changes in LC/LU on this natural catchment, the decreasing trends in long-term sediment transport were compared with meteorological values, daily rainfall, and snow days. It is concluded that the intensity characteristics of the rainfall should be investigated more in detail and could provide much more tangible information regarding climate change impacts. Some targets for future monitoring design and research techniques are set. Full article

Drought events are critical environmental threats that yield several socioeconomic impacts. Such effects are even more relevant for South America (SA) since different activities essential for the continent, such as agriculture and energy generation, depend highly on water resources. Thus, this study aimed to evaluate future changes in precipitation and hydrological drought occurrence in SA through climate projections from eight global climate models (GCMs) of CMIP6. To this end, statistical downscaling was applied to the projections obtained using the quantile delta mapping technique, and the method proved to be efficient in reducing systematic biases and preserving GCMs’ trends. For the following decades, the results show considerable and statistically significant reductions in precipitation over most of SA, especially during the austral spring, with the most intense signal under the SSP5-8.5 forcing scenario. Furthermore, GCMs showed mixed signals about projections of the frequency and intensity of drought events. Still, they indicated agreement regarding the increased duration and severity of events over the continent and a substantial proportion of moderate and severe events over most of Brazil during the 21st century. These results can be helpful for better management of water resources by decision-makers and energy planners. Full article

This paper presents a comprehensive review of low-carbon materials and construction techniques commonly used in vernacular buildings. The study highlights the relevance of vernacular architecture in the context of the shift towards sustainable construction practices. A combination of a climatic zone map, vernacular language type map, and continent map is used to identify the vernacular regions. Eight bio-based low-carbon materials, including wood, adobe, rammed earth, cob, sod, thatch, bamboo, and straw bales, are discussed, along with their characteristics, availability, and environmental impacts. The construction techniques associated with these materials are explained, emphasizing their simplicity, cost-effectiveness, and adaptability. The paper also explores two important design approaches: design for disassembly and design for modularity that were used in vernacular building. The review found the use of low-carbon materials and construction techniques derived from vernacular architecture can contribute to minimizing waste, reducing environmental impacts, and promoting a circular economy in the building industry. This research provides valuable insights for architects, engineers, and policymakers seeking sustainable alternatives in the construction sector. Full article

This study analyzed long-term extreme precipitation indices using 4 × 4 km gridded data obtained from the National Meteorological Agency of Ethiopia between 1981 and 2018. The study examined trends in extreme precipitation over three districts (Lay Gayint, Tach Gayint, and Simada) in the northwestern highlands of Ethiopia. Innovative Trend Analysis (ITA) and Mann–Kendall (MK) trend tests were used to study extreme precipitation trends. Based on the ITA result, the calculated values of nine indices (90% of the analyzed indices) showed significant increasing trends (p < 0.01) in Lay Gayint. In Tach Gayint, 70% (seven indices) showed significantly increasing trends at p < 0.01. On the other hand, 60% of the extreme indices showed significant downward trends (p < 0.01) in Simada. The MK test revealed that 30% of the extreme indices had significantly increasing trends (p < 0.01) in Lay Gayint. In Tach Gayint, 30% of the extreme indices showed significant increasing trends at p < 0.05, while 10% of the extreme indices exhibited significant increasing trends at p < 0.01. In Simada, 20% of the extreme indices showed significant increasing trends at p < 0.05. Overall, the results showed that the ITA method can identify a variety of significant trends that the MK test misses. Full article

Climate change can have an influence on rainfall that significantly affects the magnitude frequency of floods and droughts. Therefore, the analysis of the spatiotemporal distribution, variability, and trends of rainfall over the Mahi Basin in India is an important objective of the present work. Accordingly, a serial autocorrelation, coefficient of variation, Mann–Kendall (MK) and Sen’s slope test, innovative trend analysis (ITA), and Pettitt’s test were used in the rainfall analysis. The outcomes were derived from the monthly precipitation data (1901–2012) of 14 meteorology stations in the Mahi Basin. The serial autocorrelation results showed that there is no autocorrelation in the data series. The rainfall statistics denoted that the Mahi Basin receives 94.8% of its rainfall (821 mm) in the monsoon period (June–September). The normalized accumulated departure from the mean reveals that the annual and monsoon rainfall of the Mahi Basin were below average from 1901 to 1930 and above average from 1930 to 1990, followed by a period of fluctuating conditions. Annual and monsoon rainfall variations increase in the lower catchment of the basin. The annual and monsoon rainfall trend analysis specified a significant declining tendency for four stations and an increasing tendency for 3 stations, respectively. A significant declining trend in winter rainfall was observed for 9 stations under review. Likewise, out of 14 stations, 9 stations denote a significant decrease in pre-monsoon rainfall. Nevertheless, there is no significant increasing or decreasing tendency in annual, monsoon, and post-monsoon rainfall in the Mahi Basin. The Mann–Kendall test and innovative trend analysis indicate identical tendencies of annual and seasonal rainfall on the basin scale. The annual and monsoon rainfall of the basin showed a positive shift in rainfall after 1926. The rainfall analysis confirms that despite spatiotemporal variations in rainfall, there are no significant positive or negative trends of annual and monsoon rainfall on the basin scale. It suggests that the Mahi Basin received average rainfall (867 mm) annually and in the monsoon season (821 mm) from 1901 to 2012, except for a few years of high and low rainfall. Therefore, this study is important for flood and drought management, agriculture, and water management in the Mahi Basin. Full article

Snow cover affects the global surface energy balance and, with its high albedo, exerts a cooling effect on the Earth’s climate. Decreases in snow cover alter the flow of solar energy from being reflected away from Earth to being absorbed, increasing the Earth’s surface temperature. To gain a global understanding of snow cover change, in situ measurements are too few and far between, so remotely sensed data are needed. This research used the medium-resolution sensor MODIS on the Terra satellite, which has been observing global snow cover almost daily since the year 2000. Here, the MOD10C2 eight-day maximum value composite time series data from February 2000 to March 2023 were analyzed to detect global and regional trends in snow cover extent for the first 23 years of the 21st century. Trends in snow cover change during different time periods (seasons and snow-year) were examined using the Mann—Kendall test and the univariate differencing analysis. Both methods produced similar results. Globally, snow cover declined two to ten times as much as it increased, depending on the season of analysis, and annually, global snow cover decreased 5.12% (not including Antarctica or Greenland) based on the Mann—Kendall test at the 95th percentile (p < 0.05). Regionally, Asia had the greatest net area decline in snow cover, followed by Europe. Although North America has the second-largest extent of snow cover, it had the least amount of net decreasing snow cover relative to its size. South America had the greatest local decline in snow cover, decreasing 20.60% of its annual (snow-year) snow cover area. The Australia–New Zealand region, with just 0.34% of the global snow cover, was the only region to have a net increase in snow cover, increasing 3.61% of its annual snow cover area. Full article

The winter climate of the northeastern Dominican Republic features steady rainfall, which sustains cash crop production. Using a representative season, December 2016–February 2017, the mesoscale climate is characterized by high-resolution reanalysis, satellite measurements and local observations, and statistical analyses of time series from an index area of 18.8–19.6° N, 70.4–69.6° W in the Cibao Valley, where cacao and coffee are grown. Winter rainfall depends on strong trade winds that push shallow stratiform convections over 100 km inland, where nocturnal drainage flows induce orographic uplift. Interannual climate variability is studied in the context of cacao and coffee production in the years 1976–2019. Lag correlations demonstrate that higher yields follow a wet autumn, a windy winter with cool sea temperatures, and a dry spring. Changes in high-value agricultural production in the northeastern Dominican Republic may be anticipated by the climatic determinants uncovered here. Full article

Due to the important role of water resources in the growth of the world’s economy, drought causes global concern for its severe worldwide implications on different sectors, such as biodiversity, farming, public water supply, energy, tourism, human health, and ecosystem services. In particular, drought events can have strong environmental and socioeconomic impacts in countries depending on rain-fed agriculture such as the ones in the Mediterranean region, which, due to a detected increase in warming and precipitation decrease, is considered a climate change hotspot. In this context, in this paper, meteorological drought in the Calabria region (southern Italy) has been characterized considering the Standardized Precipitation Index (SPI) evaluated at different timescales. First, the temporal distribution of the most severe dry episodes has been evaluated. Then, a trend analysis has been conducted considering the different seasons, the wet (autumn and winter) and dry (spring and summer) periods, and the annual scale. Finally, the relationship between drought and some teleconnection patterns (the North Atlantic Oscillation—NAO, the El Niño–Southern Oscillation—ENSO, and the Mediterranean Oscillation—MO) has been investigated. Results show that the majority of the severe/extreme drought events have been observed between 1985 and 2008. Moreover, a decrease in SPI values has been observed in winter and spring, in both the wet and dry periods, and upon the annual scale considering the 12-month SPI and the 24-month SPI. Finally, a link between the drought episodes in the Calabria region and the NAO phases and the MO has been identified. Since drought episodes can severely impact water resources and their uses, the findings presented in this work can be useful to plan and manage the water supply for household, farming, and industrial uses.

Climate change impacts, the resulting spatiotemporal changes, and growing uncertainty exert pressure on city leaders and policy makers to create climate adaptive development strategies worldwide. This article introduces climate urbanism as a new development paradigm that advocates for a climate adaptive urban development process, safeguarding urban economics and infrastructure, and ensuring equitable implementation of related strategies. The objective of this article is to determine how far a climate vulnerable city in the Global South has progressed toward climate urbanism. The study employs Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to develop a conceptual framework. Afterward, the analytical hierarchy process (AHP) and indexing are used to develop a multicriteria decision analysis (MCDA) method to assess the selected climate sensitive factors related to climate urbanism. Findings reveal that the city of Khulna’s climate urbanism index score is 0.36, which is extremely low and denotes subpar urban performance. ‘Climate Conscious Governance’ and ‘Climate Smart Infrastructure’ contribute little, while ‘Adaptive and Dynamic Urban Form’ and ‘Urban Ecosystem Services’ contribute even less. The binary logistic regression analysis reveals the significant indicators of (transformative) climate urbanism. The article provides a critical lens for stakeholders to evaluate climate urbanism and promote urban sustainability in the face of climate change. Full article

Our aim was to investigate the association between climate anxiety and mental health in a general adult population. Cross-sectional data of the general adult population were used (n = 3091 individuals aged 18 to 74 years; March 2022). The Climate Anxiety Scale was used to assess climate anxiety. Probable depression was quantified using the PHQ-9, and the GAD-7 was used to assess probable anxiety. Adjusted for sex, age, marital status, having children in the household, highest level of school education, employment situation, smoking behavior, alcohol intake, frequency of sports activities, chronic illnesses and self-rated health and coronavirus anxiety, multiple logistic regressions showed that a higher climate anxiety was associated with a higher likelihood of probable depression (OR: 1.37, 95% CI: 1.25–1.50). Moreover, regressions showed that a higher climate anxiety was associated with a higher likelihood of probable anxiety (OR: 1.27, 95% CI: 1.15–1.40). In conclusion, our study demonstrated an association between climate anxiety and mental health in Germany. Further research (e.g., based on longitudinal data) is required to confirm our study’s findings. Full article

As climate change has intensified flood risk and damage in many low-lying areas of the world, small and medium-sized enterprises (SMEs), which typically exist in developing countries, have endured high flood risks without much support for relief. This study investigates how SMEs in flood-prone areas of Colombo, Sri Lanka, the largest business hub in the country, have perceived and dealt with flood loss and damage in the past ten years. We conducted field surveys and a questionnaire survey among 60 SME owners in two flood-prone administrative units from March to June 2020. The results show that informal businesses experienced more flood loss and damage than other community members. Also, the community dominated by informal businesses tended to be located closer to potential flood sources. Ownership and awareness about flood insurance were very low in our study areas. Temporary business closure was the most serious loss experienced by informal business communities. These communities depended on personal savings to recover from floods. Our multiple regression analysis found that age, education, and experience significantly influenced SME owners’ perceptions and experiences about floods. After discussing these findings, this paper offers recommendations to mitigate disaster loss and damage to SMEs. In particular, it highlights the importance of community-level awareness and mitigation efforts rather than administrative unit-level mitigation plans. Also, the government needs to register informal businesses by providing a more flexible business registration mechanism. Full article
