The report finds that human-caused climate change significantly increased extreme heat and health risks globally from December 2024 to February 2025. At least 1.8 billion people experienced temperatures at least twice as likely due to climate change every day of the period, with exposure peaking at 3 billion people on February 28, 2025. Africa was particularly affected, with 293 million people experiencing 30 or more 'risky heat days' added by climate change. The analysis also highlights that 110 out of 220 analyzed countries and 287 out of 940 cities saw the average person experience strong climate influence for at least one-third of the season.

The Green Climate Fund (GCF) proposal, implemented by the UNDP, seeks USD 103.25 million in grants to advance the 'Early Warnings for All' (EW4All) initiative across seven vulnerable countries. The project focuses on four pillars: disaster risk knowledge, observation and forecasting, warning dissemination, and preparedness and response. It aims to reach millions of direct and indirect beneficiaries by upgrading hydrometeorological infrastructure, implementing AI-driven forecasting, and establishing inclusive, last-mile communication protocols, with a strong emphasis on gender and disability inclusion.

The report provides a comprehensive climate risk profile for Fiji, detailing observed and projected climatic changes, specific hazards such as tropical cyclones and sea-level rise, and their impacts on target communities and ecosystems. It emphasizes the disproportionate vulnerability of women and marginalized groups and recommends specific nature-based solutions (NbS) and gender-responsive measures to enhance climate resilience across six districts: Kubulau, Dawasamu, Nakorotubu, Namalata, Bua, and Bureta.

The study identifies Guasave and Escuinapa as the most vulnerable municipalities to extreme rainfall events in Sinaloa, Mexico, using a model that weights geographic exposure and economic conditions as the primary determinants of vulnerability.

A Spring 2025 survey of 2,164 Indian adults reveals high levels of concern and personal experience with global warming, with 90% of respondents worried and 89% reporting personal experience of its effects. While a majority believe global warming is human-caused and support a transition to renewable energy, significant knowledge gaps exist regarding specific causes, such as livestock emissions. The report also highlights severe vulnerability, with 64% of households requiring several months to recover from a severe flood and 30% having moved or considered moving due to weather-related disasters.

The report reveals that while 50% of Indians have limited or no knowledge of global warming, 84% believe it is happening after receiving a definition, and 88% are worried about it. There is strong public support for transitioning from coal to renewable energy, with 82% favoring a ban on new coal plants and 86% supporting the national goal of net-zero carbon pollution by 2070. However, significant vulnerabilities persist, as 66% of respondents experience daily electricity disruptions and 43% lacked sufficient clean drinking water at least once in the past year.

Climate Central's Ocean CSI analysis indicates that Cyclone Chido intensified over waters made significantly warmer by human-caused climate change, with some temperature spikes being up to 92 times more likely due to global warming.

A study by scientists from the Philippines, UK, and Netherlands found that human-induced climate change, primarily from burning fossil fuels, increased the likelihood of the potential intensity observed during the 2024 late typhoon season in the Philippines by a factor of 1.7. The analysis focused on the sequence of six storms hitting northern Luzon, including Super Typhoon Man-Yi, and found that the probability of at least three major typhoons making landfall in a single year has increased by 25% in the current 1.3°C warmed climate compared to a world without fossil fuel combustion.

The document reports that 2024 is on track to be the hottest year on record, with global temperatures exceeding 1.5°C above pre-industrial levels for the first time. In the U.S., 24 billion-dollar disasters occurred through November 2024, resulting in at least 418 deaths and $61 billion in damages, excluding the costs of Hurricanes Helene and Milton. The analysis highlights a shrinking interval between such disasters, falling to an average of 12 days in 2024 compared to 82 days in the early 1980s.

In November 2024, the Western Pacific saw a record four simultaneous named tropical systems—Typhoon Yinxing, Typhoon Toraji, Super Typhoon Usagi, and Super Typhoon Man-Yi—all of which experienced rapid intensification due to warmer-than-average sea surface temperatures. Analysis using the Climate Shift Index: Ocean indicates these temperatures were made up to 40 times more likely by human-caused climate change. The Philippines was severely affected by 16 tropical cyclones or their remnants this season, resulting in at least 160 deaths and the displacement of over 9 million people due to flooding, landslides, and infrastructure damage.

The project utilizes paleotempestology—analyzing sediment cores from lagoons, stalagmite isotopic records, tree rings, and corals—to reconstruct past tropical cyclone activity. Key findings indicate that higher sea surface temperatures in the Atlantic correlate with increased hurricane activity, with notable peaks during the Medieval Warm Period (AD 900-1100) and since 1980. The research also identifies an inverse phase relationship in hurricane landfalls between Central America, the Eastern Caribbean, and the US East Coast, suggesting that the Intertropical Convergence Zone (ITCZ) and tropical anticyclones are critical drivers of coastal risk. Additionally, the study expanded its scope to the Pacific coast of Mexico, identifying an extreme event in Baja California Sur approximately 500 years ago.

The report finds that human-induced climate change increased the intensity and likelihood of heavy rainfall associated with Hurricane Milton in central Florida. Using the IRIS model, the analysis indicates that climate change increased the frequency of storms with Milton's wind speeds by approximately 40%, meaning the storm would have likely made landfall as a Category 2 rather than a Category 3 hurricane without global warming. Additionally, sea surface temperatures along Milton's track were 1°C warmer than in a world without climate change, making such temperatures 400 to 800 times more likely. The report also assesses Florida's adaptation measures, noting that while building codes are among the toughest in the US, the state's planning remains largely reactive and fails to adequately address social vulnerabilities in low-income and minority communities.

The analysis finds that climate change made rainfall approximately 10% heavier in both the coastal and inland regions affected by Hurricane Helene and increased the likelihood of such rainfall totals by 40% and 70%, respectively. The study also indicates that climate change increased the number of storms with similar wind speeds by about 150% and made the record-hot sea surface temperatures over the storm's track 200-500 times more likely. While the storm was well-forecast, high death tolls occurred inland due to mountainous terrain, poor infrastructure, and a lack of experience with hurricanes.

The document analyzes the failure of the National Hurricane Center (NHC) and the Mexican Meteorological Service to accurately predict the path and intensity of Hurricane John in 2006, which led to five deaths and heavy flooding in Baja California. Research by the Universidad Nacional Autónoma de México (UNAM) indicates that the predictive errors were caused by a critical lack of upper air soundings and divergences between numerical models. The text advocates for adhering to World Meteorological Organization (WMO) standards of at least four air soundings per day to improve forecast reliability.

The document examines the unique vulnerabilities of older people to climate change, noting that by 2050 up to 250 million older adults may face dangerously high temperatures. It highlights a lack of binding international agreements to safeguard their rights and references a 2024 European Court of Human Rights ruling regarding the Swiss Parliament's failure to protect older women. The paper concludes that older adults are a vital resource for climate action due to their economic power and local environmental knowledge.

The project addresses climate-related risks in western North America, specifically focusing on weather extremes, water scarcity, and food security. It aims to strengthen adaptive management by promoting the exchange of climate information between scientists and policymakers in northwestern Mexico and the southwestern United States, while examining the role of cyclone precipitation in reservoir storage and the tradeoffs between water augmentation and energy consumption.

The project focuses on enhancing disaster prevention in the Eastern Pacific by reconstructing historical cyclone records, studying lightning as a proxy for intensification, and utilizing high-resolution ocean and atmospheric models (HWRF) to improve storm surge and track forecasts.

The document details how rising sea surface temperatures, driven by human-caused climate change, are increasing the frequency and intensity of rapid intensification in tropical cyclones. It highlights that 70% of billion-dollar tropical cyclones in the U.S. since 1980 underwent rapid intensification, contributing to over $1.4 trillion in damages and nearly 7,000 deaths.

The study finds that climate change increased rainfall intensity in Taiwan and Hunan province and contributed to a 7% increase in maximum wind speeds for similar storms in the Western North Pacific basin. While sea surface temperatures as hot as those observed during Typhoon Gaemi were "almost impossible without climate change", the analysis did not identify a significant trend for rainfall in the northern Philippines. The report highlights that existing urban plans and flood infrastructure are unable to withstand climate-driven extreme floods, particularly in areas of unplanned urban development like Metro Manila.

Hurricane Beryl, the earliest Category 5 hurricane on record, was fueled by ocean temperatures 2°–3°F warmer than normal, conditions made 100–400 times more likely by human-caused climate change.
