The document details how a warming climate will increase the frequency and severity of heat waves and heavy precipitation in the Midwest, leading to higher mortality, infrastructure damage, and agricultural losses. It highlights specific risks to the Great Lakes shipping industry due to falling water levels and the threat to public health from water-borne diseases and combined sewer overflows in cities like Chicago and Milwaukee.

The Southwest is projected to warm by 4-6°F under lower-emissions and 7-10°F under higher-emissions scenarios by the end of the century. The region faces severe water scarcity, expanding deserts, and reduced runoff, particularly in the Colorado River system. Public health risks include increased heat-related deaths in Los Angeles and worsening air quality. Economic threats include reduced yields for California specialty crops, diminished ski resort profitability due to snowpack loss, and reduced aircraft freight capacity at high-altitude airports like Phoenix and Denver. Biodiversity is critically threatened, especially in the Madrean Pine-Oak Woodlands, while mountain ecosystems face range reductions and reproductive failures in wildflowers due to earlier snowmelt and spring frosts.

The document outlines a methodology for calculating urban indicators using open-source geospatial data and zonal statistics, enabling cities to benchmark their performance against global goals like the Sustainable Development Goals.

Climate change increases human health risks in the U.S. through more intense heat waves, prolonged wildfire seasons, and severe flooding that compromises water quality. Specific examples include the increased likelihood of drought conditions similar to those seen in Texas in 2011 and the lengthening of allergy seasons.

The document argues that Ethiopia's current economic development targets, as outlined in the 10-Year Development Plan (10-YDP), may be unsustainable because they increase water stress and climate vulnerability. While climate action is increasingly integrated into economic planning, the paper finds that national planning fails to adequately account for water resource requirements and their vulnerability to climate shocks. The authors suggest that water use efficiency alone is insufficient and call for proactive, cross-sectoral, and multilevel water-sensitive governance to prevent water challenges from undermining development gains.

The analysis finds that existing corporate disclosure guidance lacks a robust, shared approach to identifying and assessing physical climate risks, featuring inconsistent terminology that rarely aligns with IPCC standards. The paper notes that some IPCC-highlighted hazards are overlooked and that there is a lack of comprehensive metrics for quantifying risk factors, although water stress and flooding are the most extensively documented hazards.

The report argues that businesses in Southeast Asia must adapt to inevitable climate impacts, such as sea level rise and extreme weather, to maintain a competitive edge. It highlights that while the private sector lags behind governments and non-profits in adaptation efforts, there are 'win-win' opportunities to align business profit with the needs of the region's most vulnerable populations.

The document examines the transition of Bangladesh's disaster management from a reactive model to a proactive, risk-reduction framework through the Comprehensive Disaster Management Programme (CDMP). It details the vulnerabilities of Bangladesh to cyclones, floods, and climate change, and evaluates the institutional mechanisms and specific outputs of CDMP Phase I (2004-2009). Key achievements include the creation of the Climate Change Cell and the Disaster Management Information Centre, though the report notes challenges such as high civil service turnover and the need to mainstream risk reduction beyond a single ministry.

The Urban Community Resilience Assessment (UCRA) is a bottom-up planning tool that integrates local neighborhood knowledge with city-wide resilience strategies. Piloted in Rio de Janeiro, Surat, and Semarang, the tool uses three dimensions—city-level vulnerability, neighborhood resilience potential, and household capacities—to identify infrastructure gaps and social needs. While the UCRA promotes inclusive planning and provides detailed local baselines, pilot results highlighted challenges including high costs, time-intensive methodology, and a lack of political leadership.

The document serves as a manual for journalists to avoid common errors when linking specific weather events to climate change. It details the methodology of 'event attribution studies'—which use climate models to compare the current world with a pre-industrial one—and provides specific guidance on reporting heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires. The guide emphasizes that while climate change increases the probability and intensity of many extremes, it is rarely the sole cause, and local factors like land use and water management often play critical roles in turning a weather event into a disaster.

The report investigates the May 2022 extreme rainfall event in Eastern Northeast Brazil, which caused 133 deaths and displaced over 25,000 people. Observational analysis indicates that 7-day and 15-day rainfall events of this magnitude are exceptionally rare in the current climate, with return periods of approximately 1-in-500 and 1-in-1000 years, respectively. While climate models exhibited systematic errors in precipitation magnitudes for this specific event, the authors conclude that human-caused climate change is at least partially responsible for increasing the likelihood and intensity of such rainfall. The study further highlights that structural vulnerabilities, including unplanned urbanisation in low-income neighbourhoods and an infrastructure deficit, significantly exacerbated the disaster's impact.

The document explains the science of extreme event attribution, which calculates how climate change alters the probability and intensity of specific weather events. It provides a detailed breakdown of how climate change influences heatwaves, floods, tropical cyclones, blizzards, droughts, and wildfires, while cautioning journalists against three common errors: ignoring climate change, attributing events without evidence, or treating climate change as the sole cause. It emphasizes that while global trends are clear for some phenomena (like heatwaves), others (like blizzards) remain highly uncertain.

The document explains how 'Extreme Event Attribution' research determines the extent to which climate change makes specific weather events more likely or intense. It warns journalists against three common errors: ignoring climate change, attributing events without evidence, or naming it as the sole cause. The guide provides detailed scientific contexts for heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires, noting that while some links (like heatwaves) are globally certain, others (like droughts or snowfall) are more complex and region-specific.

The document explains 'extreme event attribution'—the scientific method used to determine if and how much climate change influenced a specific weather event. It warns journalists against three common mistakes: ignoring climate change, attributing events without evidence, or citing it as the sole cause. The guide provides detailed analysis for heatwaves, floods, tropical cyclones, heavy snow, droughts, and fires, noting that while heatwaves are unilaterally linked to global warming, other events like droughts and snowfall have more complex, region-specific relationships with climate change. It emphasizes that disasters result from both extreme weather and societal vulnerability.

The document explains the methodology of 'extreme event attribution' to help journalists avoid common errors, such as ignoring climate change or attributing an event to it as a sole cause. It details how scientists use climate models to compare the modern world with a pre-industrial one to determine if an event was more likely or intense due to global warming. The guide provides specific scientific consensus and limitations for heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires, emphasizing that while some connections are robust (e.g., heatwaves), others are more complex and depend on regional data and human vulnerability.

The document explains the science of extreme event attribution, detailing how researchers use climate models and historical data to determine if climate change made a specific event more likely or intense. It provides specific guidance on reporting various phenomena—heatwaves, floods, tropical cyclones, snowfall, droughts, and wildfires—highlighting where scientific confidence is high and where uncertainties remain.

The document serves as a style guide for journalists to avoid common errors when attributing extreme weather to climate change. It explains the methodology of event attribution studies—comparing simulated worlds with and without human influence—and provides specific guidance on reporting heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires. The guide emphasizes that while climate change increases the probability and intensity of many events, it is rarely the sole cause, and social vulnerability often determines whether a weather event becomes a disaster.

The document explains 'event attribution' science, which quantifies how climate change alters the probability and intensity of specific weather events. It provides a detailed breakdown of how climate change affects heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires, while cautioning journalists against common errors such as treating climate change as the sole cause of a disaster or ignoring it entirely. It emphasizes that while some trends are globally consistent (e.g., heatwaves), others are regionally variable or complex (e.g., droughts and snowfall).

The report attributes the 2022 West African floods to a combination of anthropogenic climate change, which significantly increased the likelihood and intensity of rainfall in the Lake Chad and Lower Niger basins, and systemic vulnerabilities including poor water management, rapid unplanned urbanization, and socioeconomic instability. In the Lake Chad region, climate change made the seasonal rainfall event approximately 80 times more likely and 20% more intense. In the Lower Niger basin, the 7-day maximum rainfall event became about twice as likely and 5% more intense. The human toll was exacerbated by the release of the Lagdo Dam in Cameroon and the proximity of settlements to floodplains.

The report investigates the 2022 Pakistan floods, focusing on two event definitions: 60-day maximum rainfall in the Indus basin and 5-day maximum rainfall in Sindh and Balochistan. While observational trends suggest that a 1.2°C warmer climate increased 5-day rainfall intensity by about 75% and 60-day rainfall by 50%, the authors refrain from a precise quantitative attribution due to high rainfall variability and climate model limitations. However, models project that a further 0.8°C of warming (reaching 2°C above pre-industrial levels) will significantly increase the intensity and probability of short-duration extreme rainfall. The study also highlights that the disaster's scale was exacerbated by outdated river management, high poverty, and gender-based vulnerabilities.
