Climate extremes over the Mid-Atlantic states: a regional approach
… as global temperatures rise, established climate ranges may no longer be applicable, as historic records for extremes such as heat waves and floods may no longer accurately predict the changing future climate. To assess extremes (present-day and future) over the contiguous United States, I …

Vegetation change in response to climate extremes in Limpopo Province, South Africa
… variability, is likely to bring about extreme climate events, such as tropical storms, heat waves, floods, and droughts. In addition, a small change in the variance and mean of climate parameters might result in a strong shift in the intensity and frequency of extreme climatic events. The …

Variability and long-term trends of climate extremes over the Limpopo, South Africa
Climate change has a crucial impact on livelihoods, economy, and water resources due to the occurrence of weather and climate extreme events such as floods, droughts and heat waves. Extreme weather has been increasing worldwide, hence the need to understand their nature and trends. The aim of this …

Climate extremes in the Southeast United States : variability, spatial classification, and related planning
… temporal trends in temperature and precipitation extremes were investigated for the Southeast United States for the period 1948 to 2012 using 27 extreme indices developed by Working Groups headed by the World Meteorological Organization. Results show region-wide warming in extreme minimum …

Flow and thermal regimes in river networks: effects of hydropower regulation and climate extremes
Interactive impacts of climate change and human activities (e.g. hydropower production) have posed urgency in examining the patterns of hydrological and thermal response in riverine ecosystems, and the potential ecological implications manifested. Hydro-geomorphic conditions are the major factors …

Genetic Regulation of Maize and Sorghum under Abiotic Stress
Climate extremes of temperature, drought and flooding continue to challenge global agricultural production and food security. If modeling studies are accurate, climate variability and drought will be a more prevalent occurrence in the future, not only inhibiting grain yield but also stressing water …

Ecosystem responses to precipitation extremes
… of changing frequencies and intensities of climate extremes have prompted ecologists to increasingly study their ecological impacts. Rising interest in this field of research reflects growing recognition that changing climatic variability can impact ecological dynamics independent of …

Evaluating temperature and precipitation extremes under 1.5°C and 2.0°C warming above pre-industrial levels: Botswana case study
The United Nations Framework Convention on Climate Change (UNFCCC) noted the need and therefore requested further quantitative research to better inform policy on the potential impacts of further warming to 1.5 and 2.0 °C above preindustrial levels. Climate extremes are expected to become more …

The Nexus of Climate Change, Biodiversity, and Food Security: A Brazil Case Study
<p> What is referred to as climate change today is the rapid warming of the climate, largely from human actions, and the effects that come with that warming. One study published by the United States Department of Agriculture (USDA) in 2021 argues that, “human-induced emissions of greenhouse gases …

Climatic trends and soil moisture feedbacks over Zimbabwe
… A statistical analysis of historical trends in climate extreme events is used and lays a foundation of projecting into future climates. A trend analysis done on rainfall patterns attained from SOMs approach compliments the RClimdex statistical approach and strengthens some of the historical …

Crop modeling for assessing and mitigating the impacts of extreme climatic events on the US agriculture system
… production is rainfed, thus is susceptible to climate change stressors such as heat waves and droughts. Process-based crop and cropping system models are important tools for climate change impact assessments and risk management. As data- science is becoming a new frontier for agriculture …

The Social Impacts of Flood on the Canadian Prairies
Climate extremes are costly environmental hazards, which create social stressors due to impacts on all human uses of land and water resources. Humans are adaptable, but their capacity for adaptation is constrained by various social factors, including social inequality. This research project asked: …

Future changes in extreme rainfall events and circulation patterns over southern Africa
Changes in precipitation extremes are projected by many global climate models as a response to greenhouse gas increases, and such changes will have significant environmental and social impacts. These impacts are a function of exposure and vulnerability. Hence there is critical need to understand …

The View From Here: Agricultural Policy, Climate Change, and the Future of Farm Women in Saskatchewan
… policy and weather. Agricultural policy and climate change are macro-level phenomena; they are “big” problems that are often seen to be outside farmers’ control, yet they have dramatic effects on both farm livelihoods and food production in general. It can be difficult to trace the everyday, …

Evaluations of historical and projected high-resolution dynamically downscaled ensemble over the continental United States
… greenhouse gas emissions will have on regional climate change. Earth system models (ESM) have been shown to accurately project changes in the climate system at a continental scale, but lack the spatial resolution needed to represent mesoscale processes that affect regional climate extremes. To …

The Applied Phycology and Biochemistry of Managed Reservoirs in the East of England
Climate Change is one of the greatest threats to drinking water supplies around the world. Managing these vulnerable systems is complex, requiring mitigation and adaptation strategies that can combat multiple stressors (i.e. drought and eutrophication). This is especially true for reservoirs in the …

Understanding the Role of Vegetation Dynamics and Anthropogenic induced Changes on the Terrestrial Water Cycle
… linkages is critical to modeling weather and climate extremes accurately. Seasonal variability in vegetation growth and human-driven land cover changes (LCC) can alter the biophysical properties of the land surface, which can in turn influence the water cycle. We quantified the impacts of …

Big Remote Sensing Data and Machine Learning for Assessing 21st Century Flooding and Socioeconomic Exposures
… impacts of hydrometeorological events and climate extremes such as flooding, rising sea levels due to climate change, solid earth changes, and other anthropogenic activities. With the increasing population in the era of changing climate, the number of people suffering from exposure to …

Bias Correction and Downscaling of Climate Model Outputs Required for Impact Assessments of Climate Change in the U.S. Northeast
<p>Global Climate Models (GCMs) are the typical sources of future climate data required for impact assessments of climate change. However, GCM outputs are related to model-related uncertainties and involve a great deal of biases. Bias correction of model outputs is, therefore, necessary before …
