The document argues that reporting on extreme weather is incomplete without explaining the climate connection. It provides specific phrasing for journalists to describe how warming temperatures 'supercharge' weather patterns and offers examples of this application across various phenomena, including heatwaves, droughts, flooding, sea level rise, winter weather, hurricanes, and wildfires. It also recommends specific attribution tools like the Climate Shift Index and World Weather Attribution to provide scientific grounding for these claims.

The document argues that climate change is a health emergency in Canada, citing record-breaking heat and wildfires in 2023. It calls on the Minister of Health to lead decarbonization of the healthcare system, address fossil fuel pollution as a root cause of health harms, and implement the National Adaptation Strategy to protect vulnerable populations.

A study by World Weather Attribution found that human-induced climate change significantly increased the intensity and likelihood of an early spring heat event in South America, which affected Argentina, Brazil, Paraguay, and Bolivia. The event, occurring approximately once every 30 years in the current climate, would have been 1.4 to 4.3 °C cooler without human-caused warming. The study notes that the likelihood of such an event has increased by at least 100 times due to climate change. Future warming of 2°C above pre-industrial levels is projected to make similar events five times more likely and 1.1 to 1.6 °C hotter. The researchers highlight a lack of heat action plans in the affected region, which increases vulnerability for the urban poor and ecosystems, despite the fact that adaptation can reduce morbidity and mortality.

Analysis using the Climate Shift Index (CSI) reveals that 97% of the U.S. population experienced at least one summer day in 2023 with temperatures made at least twice as likely by climate change. The strongest impacts were concentrated in the U.S. South, Southwest, and Southeast, with San Juan, Puerto Rico, and Victoria, Texas, among the most affected cities. The period was also characterized by record-breaking heat streaks and a record number of billion-dollar weather disasters in the U.S.

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.

The document details a pilot project in Burkina Faso's Plateau-Central region that uses a standardized Risk and Vulnerability Assessment (RVA) to create a Regional Adaptation Plan (RAP). This regional approach aims to refine national adaptation strategies by addressing local specificities, specifically targeting vulnerable groups and key sectors like agriculture and health.

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.

Analysis of July 2023, likely Earth's record hottest month, shows that human-caused climate change significantly increased the likelihood of extreme heat globally. Using the Climate Shift Index (CSI), the report finds that 6.5 billion people experienced at least one day where heat was at least three times more likely due to climate change. Particularly strong influences were noted in the Caribbean, Mexico, the southern U.S., and parts of Africa and Asia. In the U.S., 73% of the population experienced at least one day at CSI level 3 or higher, with several cities in Florida, New Mexico, and Arizona showing the strongest climate fingerprints.

The report finds that while a majority of Americans believe allergy seasons have remained stable, 38% perceive them as becoming more severe, with the strongest perception of increase among those most concerned about climate change.

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 report finds that a three-day extreme heat event in Uttar Pradesh from June 14-16, 2023, was made at least two times more likely by human-caused climate change, with some areas seeing a three-fold increase in likelihood. The event resulted in at least 34 fatalities in Ballia and led to school closures in Bihar. The analysis highlights that the combination of extreme heat and high humidity increased the severity of the event, following a previous humid heat wave in April 2023 that was made over 30 times more likely by climate change.

The Regional Workshop on Climate, Environment, and Health, held in March 2023 in San Martín de los Andes, Argentina, focused on strengthening public institutional capacity to address environmental determinants of health (EDHs) in the Americas. The event convened nearly 100 experts from 20 countries to promote transdisciplinary and intersectoral collaboration. Key outcomes included the development of 13 seed grant proposals addressing issues such as dengue, heatwaves, and zoonoses, and the announcement of the Belmont Forum Collaborative Research Action (CRA2) funding call. The workshop also highlighted local climate and health initiatives in Neuquén Province, including GHG inventory efforts in San Martín de los Andes and vector-borne disease control in Neuquén Capital.

The June 2021 heat wave in British Columbia was the deadliest disaster in the province's history, resulting in 619 direct heat-related deaths. The report estimates the societal cost of these lives lost at $5.5 billion using the Value of a Statistical Life (VSL) metric. Beyond mortality, the event caused $12 million in healthcare costs, significant agricultural revenue losses (at least $25 million), and disruptions to electricity and transportation infrastructure. Vulnerabilities were exacerbated by a lack of mechanical cooling in homes, inadequate urban greening, and institutional failures in disaster response and communication. The report argues that without adaptation, heat-related hospitalizations could double by 2030 and annual deaths could average 1,370 by 2030. Key recommendations include updating building codes for mechanical cooling, increasing urban forest canopies, improving weather warning lead times to three days, and implementing independent public reviews of disaster responses.

A collaborative study by international scientists found that the extreme heatwave in the Western Mediterranean from 26-28 April 2023 was likely made at least 100 times more probable by human-induced climate change. The event, which saw temperatures up to 20 degrees higher than normal and broke national records in Spain and Portugal, would have been at least 2°C cooler in a world 1.2°C colder. The researchers note that climate models likely underestimate the increase in extreme heat in Western Europe, suggesting their findings are conservative.

The report finds that majorities in all 73 surveyed low-emission areas have experienced extreme weather, with unusually hot weather being the most common hazard. Most respondents attribute these events to climate change, yet significant gaps in individual and household preparedness exist, particularly in South America and Europe. Recovery times vary widely, with some populations in Central Asia and the Balkans expecting recovery to take a year or more.

The document explains attribution studies—which use climate models to determine if and how much human-induced climate change affected a specific event—and provides guidance on reporting various extreme phenomena. It details how global warming increases the probability and intensity of heatwaves and heavy precipitation globally, while the effects on droughts, wildfires, and tropical cyclones vary by region or specific metric. It emphasizes that while climate change influences the risk and intensity of these events, human factors like land use and water management also contribute to whether an event becomes a disaster.

Climate Central's analysis of 247 U.S. locations shows a significant shift toward heat records over cold records, with 96% of locations setting more heat records in the 2010s compared to 54% in the 1910s. From January 2020 to November 2022, 91% of analyzed locations saw more record heat than cold, with some cities like Tampa and Miami setting only heat records. The report links these local trends to global warming, noting that daily heat records in the U.S. have become at least twice as frequent as cold records, increasing risks for health, ecosystems, and infrastructure.

The report examines the failures of water privatisation in Europe, citing infrastructure decay and high profits in the UK and France, while highlighting successful re-municipalisation in Paris and public resistance in Greece, Ireland, and Italy. It advocates for public ownership and cross-border cooperation to manage water as a public security issue and a public good, rather than a commodity, to effectively adapt to climate change.

World Weather Attribution (WWA) reports on its activities from October 2021 to October 2022, during which it published eight rapid analyses and several peer-reviewed papers. These studies examined the role of human-induced climate change in events such as heatwaves in India, Pakistan, and the UK, as well as flooding and droughts in various regions. The organization emphasizes that while climate change is a major driver for heatwaves, its role in other events like tropical cyclones can be less clear, often compounding with high levels of vulnerability to increase human impacts.

The document describes how the organization Neighbours United used deep canvassing—a listening-based outreach method—to overcome climate skepticism in Trail, British Columbia. By conducting 1,181 in-depth conversations focused on storytelling rather than facts, the campaign achieved a 40% persuasion rate, leading the city council to unanimously vote in April 2022 to transition to 100% renewable energy by 2050.
