Using the Statistical Downscaling Tool (SDSM) and the Soil and Water Assessment Tool (SWAT), the study projects that while the Gilgel Abay River may experience a decrease in precipitation and flow volume between 2010 and 2040, these trends are expected to reverse with significant increases by 2070-2100. Overall, climate change is projected to increase annual flow volume, potentially benefiting small-scale irrigation and dam projects, though low flow conditions are expected to remain largely unaffected.

The report analyzes the intersection of climate threats and socio-economic vulnerabilities in the Yaque del Sur basin, the Dominican Republic's third-largest basin. It finds that the region faces severe water deficits and high vulnerability due to poverty and dependence on climate-sensitive agriculture. Projected climate trends include rising temperatures and decreasing precipitation, which could lead to an annual water deficit of 390 million m3 by 2050. The document identifies critical gaps in institutional coordination between disaster risk management and climate change adaptation bodies. To mitigate these risks, it recommends seven priority actions, including switching to drought-resistant crops like sorghum and mangoes, increasing irrigation efficiency from 20% to 45%, and implementing payment for ecosystem services to promote reforestation in the upper basin.

The report identifies Honduras as highly vulnerable to climate risks, particularly in its small-scale agricultural sector, which is critical for food security and employment. It details current threats such as droughts, hurricanes, and floods, and projects a hotter, drier future that could significantly reduce maize and bean yields. The document evaluates the country's existing disaster risk and climate adaptation frameworks, noting a lack of integration between the two and significant gaps in meteorological data. It recommends a combination of local technical measures—such as improved water management, soil conservation, and crop diversification—and governance reforms to incorporate climate risk into national agricultural policies.

The report finds that the US Midwest has experienced a significant increase in dangerously hot and humid summer days since the 1940s and 1950s. This trend increases the risk of heat-related illnesses and deaths, particularly for vulnerable populations such as the elderly, children, and urban residents. The analysis, covering 10 cities across eight states, indicates that rising nighttime temperatures and more frequent heat waves exacerbate health risks. Projections suggest that without significant carbon emission reductions, the region will face a substantial increase in days exceeding 90°F and 100°F by the end of the century.

The report finds that the U.S. Midwest has experienced a significant increase in dangerously hot, humid, and dry summer days, as well as more frequent heat waves, over the last 60 years. Analysis of ten cities indicates that nighttime temperatures and humidity are rising, reducing the relief typically found overnight. These trends are linked to higher risks of hyperthermia and dehydration, particularly for vulnerable populations such as the elderly and low-income urban residents. The document argues for a combination of local adaptation strategies, such as heat-response plans and cooling centers, and aggressive global action to reduce fossil fuel emissions to mitigate future extreme heat events.

The ClimateCost project analysed three emissions scenarios (A1B, E1, and RCP8.5) to project temperature and precipitation changes. Findings indicate that global temperatures could rise by 2.4°C to 3.4°C by 2071-2100 under the A1B scenario, with Europe experiencing more intense summer warming, particularly in the south. While the E1 mitigation scenario reduces these increases, projections for all scenarios do not significantly diverge until after 2040, emphasizing the need for immediate adaptation. Precipitation projections show higher uncertainty, but suggest wetter winters for Northern Europe and drier conditions for Southern Europe.

Sudan is highly vulnerable to climate change due to its reliance on rain-fed agriculture, with projections indicating significant declines in crop yields and increased water scarcity by 2060. The document argues that while the country has established frameworks like the Environmental Protection Act of 2001 and the National Adaptation Program of Action (NAPA), effective adaptation is hindered by political instability, top-down planning, and land tenure conflicts. It recommends a comprehensive approach including land tenure reform, a national early warning system, and the integration of climate risks into all levels of national development planning.

The report projects that Iowa will face significantly hotter summers, increased flooding in winter and spring, and new threats to agriculture due to climate change. Under a higher-emissions scenario, Des Moines could see over 85 days per summer above 90°F and frequent heat waves similar to the 1995 Chicago disaster. Agriculture is threatened by heat stress for corn and livestock, as well as the northward expansion of pests like the corn earworm. The document argues that Iowa can mitigate these risks by strengthening its renewable electricity standard, promoting energy efficiency, and banning coal plants without carbon capture and storage, supported by federal cap-and-trade and fuel economy standards.

The report projects that Indiana will face significantly hotter summers, increased flooding, and agricultural disruptions if heat-trapping emissions continue to rise. It highlights severe risks to public health from heat waves and poor air quality, and suggests that the state transition from its heavy reliance on coal-fired power to renewable energy and energy efficiency to mitigate these effects.

The document details how rising temperatures in the Northwest are reducing springtime snowpack and shifting streamflow timing, which threatens water supplies, hydropower production, and salmon populations. It also highlights risks of increased forest fires, pest infestations, and coastal erosion due to sea-level rise, particularly in the Puget Sound region.

The report analyzes how varying levels of greenhouse gas emissions will lead to temperature increases in California, ranging from 3 to 10.5 °F by the end of the century. It details severe risks including a 70-90% reduction in Sierra Nevada snowpack, increased frequency of extreme heat and wildfires, and rising sea levels that threaten coastal infrastructure. The document emphasizes that while some changes are inevitable, the most severe outcomes can be avoided through aggressive emission reductions, aligned with California's executive goals to return to 1990 emission levels by 2020.

The report assesses how rising temperatures and shifting precipitation patterns will affect the Great Lakes region, predicting warmer, drier summers and increased extreme weather. It details vulnerabilities in aquatic and terrestrial ecosystems, agriculture, and human health, while recommending emission reductions and adaptive management.

The case study evaluates the PRECIS Regional Climate Model (RCM) and Tropical Storm Model (TSM) to project wind climate trends in Barbados. While the RCM showed some biases in baseline simulations, projections from the aenwh-driven model suggest small increases in mean wind speed and a higher frequency of days exceeding 8 ms-1 by the 2080s. The TSM 'what if' scenarios indicated that Hurricane Katrina would cause the most damage due to the longest persistence of maximum wind speeds. These findings highlight risks to coastal infrastructure, utility plants, and port operations, suggesting a need for updated building codes, extended setback limits, and the restoration of natural buffers like reefs and mangroves.

The study finds that drought events in Las Tunas province, similar to the severe 2003-2005 event, are projected to become more frequent and intense through 2050, driven by reduced precipitation and increased evaporation from rising temperatures.

The study finds that the SPEI 12 drought index correlates with forest fire occurrence, particularly during severe and extreme drought events, though 'Milpa' farming remains the primary cause of fire escapes. Projections indicate that future drought events in the region will become more frequent, with an average recurrence time of 1 in 5 years, increasing the risk of escaped agricultural fires.

This report provides a risk and vulnerability assessment of water resources in the Limpopo Water Management Area (WMA) of South Africa. It analyzes current water resource stresses, observed and projected climate trends, and the resulting vulnerabilities to ensure sustainable water management.

The project addresses the lack of long-term climate data in the tropical Andes by combining dendrochronology, improved hydrometeorological networks, in-situ digital sensors, and global circulation models. These diverse data streams—including tree-ring chronologies spanning 100 to 200 years and simulations for 2011-2030 and 2045-2065—are integrated to reduce uncertainty in climate projections and inform the NatureServe vulnerability index for conservation management.

The IISD Experimental Lakes Area (IISD-ELA) reports that mean annual air temperatures in Northwestern Ontario have increased by 0.42°C per decade since 1969, exceeding the global average. This warming is contributing to shorter lake ice cover durations, which are projected to decline by another 20–30 days by 2070. The document also notes that lake trout are experiencing habitat loss due to rising surface temperatures and low bottom-water oxygen, and their average length has decreased since the 1970s due to longer summer periods restricting food access. Additionally, the report highlights a trend of lakes becoming darker in Europe and North America due to increased dissolved organic carbon from precipitation.

The report projects substantial warming and shifting precipitation patterns for the US Midwest, with extreme heat events and heavy rainfall becoming more frequent. Under a higher emissions scenario, end-of-century temperatures could rise by up to 10°F, significantly increasing the frequency of severe heat waves and reducing snow cover. While annual precipitation may only increase slightly, winter and spring are expected to become wetter, while summer precipitation may decrease under higher emissions. These changes are projected to increase heat-related mortality and flooding risks across the region.

Alaska has warmed at more than twice the rate of the rest of the United States over the last 50 years, leading to significant permafrost thaw, coastal erosion, and disruptions to marine and terrestrial ecosystems. These changes threaten public infrastructure, commercial fisheries, and the survival of ice-dependent species like polar bears.
