The document also highlights the health risks of extreme heat, particularly for vulnerable populations and those affected by urban heat islands, and provides a directory of monitoring tools and hurricane season resources.

Between 2000 and 2023, 80% of major U.S. power outages were caused by weather, with a significant increase in frequency during the last decade. Severe weather, winter storms, and tropical cyclones are the primary drivers, with Texas and the Southeast region among the most affected. The document highlights the vulnerability of aging infrastructure and the disproportionate impact on marginalized and medically vulnerable populations, while suggesting grid hardening, microgrids, and emissions reductions as paths toward resilience.

The report finds that while only 5% of event-related local television segments provided climate change context, these segments reached over 17 million people across the 50 largest U.S. media markets. Audiences surged during extreme events, with local television viewership doubling in Orlando during Hurricane Ian and increasing 78% in Los Angeles during Tropical Storm Hilary. Extreme heat events, specifically the July 2023 heat streak in Phoenix, were most frequently linked to climate change, accounting for 48% of all climate-contextualized segments. Analysis of closed captioning shows that 96% of contextualized segments highlighted major impacts in categories such as health and safety, vulnerable communities, power supply, the economy, and travel disruption.

The U.S. experienced a record 28 billion-dollar disasters in 2023, causing over $93 billion in damages. Since 1980, tropical cyclones have been the costliest events, while severe storms are the most frequent. The document details how warming temperatures intensify specific hazards—such as increasing rainfall intensity and fueling stronger tropical cyclones—and notes that the average time between such disasters has shrunk from 82 days in the 1980s to 12 days in 2023.

The report details how Hawaii is experiencing accelerating climate crises, specifically through extreme drought, intense tropical storms, sea level rise, and increasing temperatures. It provides comprehensive lists of potential costs for mitigation and adaptation, ranging from water management and wildfire suppression to floodproofing infrastructure and public health interventions.

The report advocates for 'Just Resilience' in Bangladesh, combining climate resilience with climate justice to prevent marginalized groups from being overlooked in adaptation planning. It examines the disproportionate impacts of climate hazards—such as salinity intrusion affecting 53% of coastal areas and erratic rainfall causing floods—on women, children, the elderly, and landless farmers. The document analyzes three key sectors: agriculture, where it highlights the need for climate-resilient crops and the Bangladesh Delta Plan 2100; disaster risk management, focusing on the National Plan for Disaster Management 2021–2025; and energy, noting the low share of renewables (2.76%) and the need for rural energy security. It concludes with recommendations for inclusive decision-making, standardized accountability metrics, and the use of biotechnology and indigenous knowledge to build equitable resilience.

Analysis using the Climate Shift Index (CSI) shows that human-caused climate change significantly increased the likelihood of record-shattering heat during the June-August 2023 period. Approximately 48% of the global population experienced at least 30 days where heat was made at least three times more likely by climate change (CSI level 3 or higher). The report highlights a stark inequity in exposure, noting that countries with the lowest historical emissions experienced three to four times more days of very strong climate fingerprints than G20 countries.

Global sea surface temperatures reached unprecedented levels from April to July 2023, driven primarily by human-caused carbon pollution and El Niño. This warming increases the likelihood of rapid intensification in hurricanes and causes severe heat stress for coral reefs, particularly around Florida and the Caribbean. The document highlights that 48% of the global ocean experienced marine heat waves in July 2023, and warns that 70–90% of tropical coral reefs could disappear even if warming is limited to 1.5°C.

The document explains the distinction between weather and climate, the human-driven causes of global warming, and the resulting increase in extreme weather events. It highlights the disproportionate impact of climate change on marginalized groups and outlines necessary solutions, including transitioning to renewable energy and improving resource efficiency.

The Resilient Homestead and Livelihood support to the vulnerable coastal people of Bangladesh (RHL) project aims to reduce the vulnerability of approximately 362,475 direct beneficiaries in seven coastal districts. With a total budget of USD 49.99 million, the project focuses on constructing 3,000 climate-resilient houses with raised plinths, establishing 50 micro-crab hatcheries to create a sustainable supply chain, and promoting goat and sheep rearing in slatted houses. The initiative specifically targets women and ultra-poor households to enhance food security and reduce urban migration caused by sea-level rise and salinity intrusion.

The document argues that climate change is increasing the frequency and intensity of floods, which leads to damp buildings and the growth of mold. This process degrades indoor air quality and poses significant respiratory and mental health risks, particularly for vulnerable populations. It highlights that mold can grow on absorbent materials within two to three days after a flood and notes that in the U.S., up to 20% of common respiratory infections may be attributed to dampness and mold.

The document argues that reporting on extreme weather without mentioning climate change is incomplete and potentially inaccurate. It provides specific phrasing and examples for connecting various weather phenomena—such as heatwaves, droughts, floods, and hurricanes—to global warming, while highlighting the role of attribution science in quantifying these links. It also recommends tools like the Climate Central 'Climate Change Index' and World Weather Attribution for real-time data.

The RHL project targets 362,475 direct beneficiaries in the coastal districts of Satkhira, Khulna, Bagerhat, Barguna, Patuakhali, Bhola, and Cox’s Bazar. It focuses on three primary outcomes: reducing asset and life loss through the construction of 3,000 climate-resilient houses with raised plinths; enhancing livelihood resilience by promoting salinity-tolerant vegetable cultivation, goat/sheep rearing in slatted houses, and the establishment of a sustainable, hatchery-based crab supply chain; and improving local climate planning through the formation of 3,200 Climate Change Adaptation Groups (CCAGs). The project is implemented by the Palli Karma-Sahayak Foundation (PKSF) as both the Accredited Entity and Executing Entity, utilizing a blend of GCF grants and PKSF loans.

Fiji employs a multi-sectoral approach to climate adaptation, utilizing a National Adaptation Plan with 160 measures and a hybrid seawall strategy combining mangroves, boulders, and vetiver grass. The government coordinates these efforts through the Climate Change Division, utilizing GIS and the Adaptation Impact Analysis Tool to monitor village-level projects. For communities facing immediate risk of inundation, Fiji has established a Standard Operating Procedure for Planned Relocations and the Climate Relocation of Communities (CROC) Trust Fund to ensure voluntary, culturally-sensitive movement to higher ground, as seen in the relocation of the village of Cogea.

Mongla, a coastal port town in Bangladesh, faces severe climate risks including sea-level rise, salinity intrusion, and frequent cyclones. While the community suffers from declining fish stocks and reproductive health issues due to water scarcity, the local government has implemented infrastructure projects such as a 11km marine drive road and flood-control gates. Under Mayor Sheikh Abdur Rahman, the town has successfully reduced casualties during extreme weather events, such as Cyclone Sitrang, through the strategic use of cyclone centers and emergency supplies. Future resilience efforts focus on expanding water treatment facilities and securing international funding for human-centric adaptation.

In Datinakhali, Bangladesh, frequent extreme weather events like cyclones and flash floods have trapped residents in a debt cycle with loan sharks. To counter this, World Vision established the Samabay Samiti, a cooperative fund committee where female members save weekly to access low-interest microloans and receive business training. The initiative has enabled members, such as Swapna Parvin, to establish diversified livelihoods in cosmetics and build household assets, leading to the program's expansion and a trial collaboration with BRAC.

In Banishanta village, Khulna district, farmers have formed the Banishanta Weather Club to combat the impacts of cyclones, floods, and high salinity. Supported by the NGO Bangladesh Environment and Development Society (BEDS) and the Delta Research Initiative (DRI), the community uses digital tools, smartphone apps, and a Facebook messenger group called 'Banishanta Climate School' to access weather forecasts and agro-advisories. This locally led adaptation approach allows farmers to make informed decisions on sowing and irrigation, reducing the economic costs of climatic disasters and improving livelihoods for smallholder farmers and the Banojibi community.

The document details how the local NGO BEDS transitioned women in the Sundarbans from using mangrove seeds as cooking fuel to establishing community-led nurseries. This shift has provided economic empowerment for women, such as Nomita Mondol, and increased mangrove coverage in the region to combat climate risks like cyclones and salinity.

The report examines climate misinformation surrounding extreme weather in Latin America, focusing on case studies in Brazil, Chile, and Peru. It finds that highly visible, multi-causal, and emotional events are frequently weaponized by political figures to assign blame to scapegoats or promote conspiracy theories, thereby obscuring the scientific drivers of the climate crisis.

The report examines climate misinformation following extreme weather events in Latin America, focusing on case studies in Brazil, Chile, and Peru. It finds that the high visibility, multi-causal nature, and emotional impact of these events make them ideal for actors to sow confusion, assign blame to scapegoats, and advance political agendas. In Brazil, a cyclone led to false claims about 'burst dams' to attack political opponents. In Chile, wildfires were framed as 'terrorist' arson to distract from a 14-year mega-drought. In Peru, Cyclone Yaku was falsely attributed to the HAARP project. The report concludes that these narratives often amplify existing political polarizations and rely on the misattribution of causes to hinder climate adaptation and mitigation efforts.
