The document argues that fossil fuel sponsorship of political gatherings, specifically the UBCM Convention, constitutes greenwashing and improperly influences municipal decision-making. It links fossil fuel combustion to severe health crises, including 8.1 million annual global deaths from air pollution and extreme weather events in British Columbia such as the 2021 heat dome and historic wildfires. The authors call for a total ban on fossil fuel advertising and sponsorship in BC municipalities, drawing parallels to the historical ban on tobacco industry influence in medicine.

The briefing links the increased frequency and intensity of US extreme weather events, such as the July 2023 heatwave and August 2024 California wildfires, to climate change driven by fossil fuels. It highlights that US oil and gas production emissions rose roughly 42% between 2011 and 2022 and notes that 88 large fossil fuel and cement companies are responsible for 48% of the rise in fire-danger conditions in the region. The document argues for corporate accountability, citing a Climate Analytics estimate that the 12 most polluting companies are responsible for USD 15 trillion in economic damages from 1985 to 2018. While the US has seen significant growth in solar and wind capacity and electric vehicle sales, primary energy consumption remains dominated by petroleum (38%), natural gas (36%), and coal (9%) as of 2023.

The authors propose a streamlined framework to detect and map extreme events—specifically heatwaves, droughts, and floods—by selecting optimal environmental indicators and thresholds. Tested in Sweden using data from 1922–2021, the framework identified increasing occurrences of heatwaves and floods in large areas, while finding no significant trend for droughts. The study also identified compound hazard hotspots in northern Sweden, where drought-heatwave and drought-flood events are positively correlated between June and August.

A late summer heat event in the eastern United States, affecting approximately 120 million people, has been made significantly more likely by human-caused climate change. The event is characterized by record-breaking temperatures, high humidity, and heat indices reaching 115°F, posing severe health risks to vulnerable populations, particularly children.

The analysis finds that human-caused climate change has significantly increased the frequency of dangerous nighttime temperatures globally, affecting billions of people. Using the Climate Shift Index, the report quantifies additional nights above 18°C, 20°C, and 25°C, noting that these temperatures disrupt sleep and increase risks of cardiovascular conditions and mortality. The most severe impacts are observed in tropical regions and urban areas due to heat island effects, with specific cities in India, Indonesia, and Africa experiencing an additional month or more of extreme nighttime heat.

The document serves as a '101' guide for journalists to report on climate change, explaining the difference between weather and climate, the primary causes of global warming, and the impacts of extreme weather. It offers specific phrasing to help reporters connect current events to climate change and distinguishes between mitigation and adaptation strategies. Additionally, it provides professional guidance on avoiding greenwashing, handling climate deniers, and centering climate justice in reporting, while emphasizing that climate coverage is based on scientific consensus rather than activism.

From June 18-20, 2024, a major to extreme heat event is forecast for the eastern half of the U.S., affecting over 25 million people. The event is characterized by record-level high temperatures in major cities and elevated nighttime temperatures. Climate Central's Climate Shift Index (CSI) indicates that human-caused climate change has made this heat at least four times more likely in several states, including West Virginia, Ohio, and Indiana.

The document serves as an introductory resource for journalists to understand the causes and impacts of climate change and how to report on them accurately. It defines key terms, explains the role of greenhouse gases and fossil fuels, and details the effects of warming on weather patterns. The guide offers specific phrasing to help reporters connect extreme weather events to human-caused climate change and distinguishes between mitigation and adaptation strategies. It also outlines international and national policy frameworks, such as the Paris Agreement and the US Inflation Reduction Act, while advising journalists on how to avoid pitfalls like greenwashing and the platforming of climate deniers.

The report finds that human-induced climate change significantly increased the frequency, intensity, and duration of extreme heat globally from May 2023 to May 2024. Using the Climate Shift Index (CSI), the study determined that 6.3 billion people experienced at least 31 days of extreme heat made at least twice as likely by climate change. It identifies 76 extreme heat waves across 90 countries and highlights critical gaps in impact reporting, particularly in developing regions. The authors advocate for City Heat Action Plans and systemic adaptations to prevent heat-related fatalities.

A World Weather Attribution study found that human-caused climate change increased the likelihood of extreme heat for 6.3 billion people globally, adding an average of 26 extreme heat days per location over the last year.

A World Weather Attribution study found that human-induced climate change significantly increased the frequency and intensity of April 2024 heatwaves across Asia. In the Philippines, the event would have been "impossible" without climate change, while in West Asia, the probability increased by a factor of 5. In South Asia, extreme temperatures were found to be about 45 times more likely and 0.85ºC hotter. The report highlights disproportionate impacts on vulnerable groups, including 1.7 million displaced people in Gaza and outdoor workers, and notes that existing heat action plans often lack mandatory workplace regulations and retrofitting for informal settlements.

A World Weather Attribution analysis concludes that the extreme heatwave affecting the Sahel in early 2024, which coincided with Ramadan and power cuts, would have been impossible without the 1.2°C of global warming caused by human activities. The event was particularly severe in Mali and Burkina Faso, where 5-day maximum temperatures had a return time of 200 years. The study finds that human-induced warming increased 5-day maximum temperatures by 1.5°C in Mali/Burkina Faso and 1.4°C across the wider Sahel, while the current El Niño event contributed only a small amount (approximately 0.2°C). In Bamako, Mali, the Gabriel Touré hospital reported 102 deaths between 1-4 April, significantly exceeding the 130 deaths recorded for the entire month of April 2023.

Between December 2023 and February 2024, carbon pollution drove abnormal warmth for approximately 80% of the global population. Roughly 4.8 billion people experienced at least one day of temperatures that would be 'virtually impossible' without climate change. The report highlights extreme temperature anomalies in the U.S. upper Midwest and Canada, as well as high Climate Shift Index (CSI) levels in tropical regions of Southeast Asia, Sub-Saharan Africa, and the Caribbean. It also documents associated extreme weather events, including record-breaking heat in Australia and deadly floods in the Democratic Republic of the Congo.

2023 was the hottest year on record, reaching 1.4°C above the 1881-1910 baseline. This warming is driven by unprecedented levels of carbon pollution from fossil fuels, leading to more frequent and intense extreme weather events globally.

In 2023, the contiguous U.S. experienced its 5th-hottest year on record, with an annual average temperature 2.4°F above the 20th century average. The year saw a record 28 billion-dollar disasters, resulting in an estimated 492 lives lost and over $93 billion in damages. Severe storms were the primary driver, accounting for 68% of these events. The frequency of such disasters has increased significantly, with the average time between events dropping to 12 days in 2023, compared to 82 days in the 1980s.

The document highlights that 2023 is virtually certain to be the hottest year on record, driven by human-caused greenhouse gas emissions. It details the resulting increase in extreme weather events, the long-term trend of rapid warming since the industrial revolution, and the necessity of transitioning to clean energy to meet global climate targets.

The document analyzes how climate change impacts public health in Senegal through heatwaves, floods, and droughts, while highlighting a community-led resilience project in Widou Thiéngoly.

The European Union lacks the preparation to manage cascading climate risks, where hazards in remote locations create knock-on effects that impact European societies and economies. The report emphasizes that with accelerating climate hazards over the next 10 to 15 years and insufficient adaptation, these impacts are inevitable. It proposes 21 strategic recommendations to move from individual understanding to systemic transformation, urging the EU to adopt a proactive rather than reactive approach to risk and resilience thinking.

Climate Central's analysis using the Climate Shift Index (CSI) reveals that 90% of the global population experienced at least 10 days of temperatures strongly influenced by climate change between November 2022 and October 2023. The study highlights that one in four people faced extreme heat streaks of at least five days driven by carbon pollution, with the strongest influences observed in the developing world and specific high-impact areas like Jamaica and several U.S. cities.

The period from November 2022 to October 2023 was the hottest 12-month stretch in recorded history, with a global average temperature 1.32°C above the pre-industrial baseline. Using the Climate Shift Index (CSI), Climate Central found that 90% of the global population (7.3 billion people) experienced at least 10 days of temperatures very strongly affected by climate change (CSI level 3 or higher). Approximately 1.9 billion people (24%) experienced a five-day heat wave strongly influenced by carbon pollution (CSI level 2 or higher). The report highlights an inequitable distribution of impacts, with small island developing states and least developed countries facing higher exposure, although heat waves also occurred in G20 nations. The analysis also links human-induced climate change to severe weather events, including deadly flooding in Africa and Libya, and record-breaking wildfires in Canada and Hawaii.
