Between August 22 and 25, 2024, over 60 million people in Brazil faced extreme temperatures and wildfires exacerbated by climate change. High temperatures were forecasted to be five times more likely due to global warming, with anomalies reaching up to 10°C above normal in São Paulo. Wildfires have burned over 760,000 hectares in the Amazon and 1.3 million hectares in the Pantanal, with climate change increasing Pantanal fire intensity by 40%. On August 20, PM2.5 pollution levels reached 11 times the World Health Organization's recommendations, causing increased respiratory illnesses and affecting 10 Brazilian states as well as Bolivia, Paraguay, and Peru.

The document argues that decisive action on climate change, specifically regulating the oil and gas industry and its financial backers, is necessary to prevent the worsening of wildfires, heat domes, and floods in Canada. It highlights the disproportionate impact of these events on Indigenous peoples and criticizes the Canadian government for prioritizing fossil fuel infrastructure, such as the Trans Mountain pipeline expansion, over emissions reductions.

The report examines how the increasing frequency and severity of climate-driven disasters lead insurance companies to raise premiums or withdraw coverage, particularly in high-risk areas of the US. This process creates a 'domino effect' where the lack of affordable insurance makes homes unmortgageable, reduces property values, and increases homelessness. The authors highlight a cycle where insurers profit from these increases and reinvest in fossil fuels, further exacerbating the climate crisis. The document warns that widespread mortgage defaults and the devaluation of lender security could lead to a systemic financial crisis with global implications.

The report finds that a majority of Americans believe global warming is happening and is mostly human-caused, with significant numbers reporting personal experience with its effects and emotional distress. While many feel a personal responsibility to act, there is a notable gap in understanding the strength of the scientific consensus, and a majority rarely discuss the issue with family and friends.

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.

The Southwest United States experienced an extreme heat event from June 6 to June 13, 2024, with human-caused climate change making high temperatures at least five times more likely. The event caused record-setting temperatures in cities like Phoenix and Las Vegas, led to numerous hospitalizations for heat exhaustion, and contributed to wildfires in California.

From June 11-13, 2024, over 290 million people in Northern Africa, the Mediterranean, and the Middle East are forecast to experience extreme heat made at least five times more likely due to human-caused climate change. Maximum temperatures of 40°C or higher are expected in several countries, including Saudi Arabia, Iraq, Syria, and Egypt. The document highlights risks including wildfires in Greece, damage to Bulgaria's rose oil production, and increased vulnerability for refugees in Libya, Tunisia, and Algeria.

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.

Between March and May 2024, global temperature records were broken for three consecutive months. Using the Climate Shift Index (CSI), the analysis found that approximately one in four people worldwide experienced temperatures at least three times more likely due to climate change (CSI level 3+) daily. Exposure peaked on April 6, 2024, with 2.7 billion people affected. The most severe impacts were concentrated in Africa, Southeast Asia, Central America, and South America, with 44% of Africa's population experiencing the most extreme attributable heat (CSI level 5 for 60+ days). The report also highlights a strong regional contrast in the U.S., where coastal areas and islands showed higher CSI signals despite lower temperature anomalies compared to the Upper Midwest.

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 identifies that climate change creates systemic stressors for the UK Home Office, ranging from direct threats to public health and infrastructure to indirect risks like societal polarization and organized crime. It argues that the Home Office must move from a reactive to a proactive posture by establishing a high-level climate security policy initiative. The proposed Action Plan is built on four pillars: exercising sustained leadership, understanding and anticipating risks through better data and literacy, collaborating with domestic and international partners, and implementing specific preventative measures to protect citizens and maintain social cohesion.

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.

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.

DASD Caroline Baxter describes the U.S. Department of Defense's (DoD) efforts to integrate climate literacy into professional military education (PME). She argues that climate change acts as a "threat multiplier" affecting installations, mission demand, and budgets. The DoD's approach focuses on making climate information mission-relevant, integrating it into existing curricula to avoid task saturation, and emphasizing readiness and lethality over political terminology. Key initiatives include the Climate Literacy Sub-Working Group, a new outcomes-based PME instruction, and a dedicated online portal for authoritative climate information.

The Spring 2024 survey of 1,031 American adults shows that 70% believe global warming is happening, with 59% attributing it primarily to human causes. While 64% of respondents express worry about global warming and 50% report personally experiencing its effects, there is a significant gap in understanding the scientific consensus, with only 21% aware that over 90% of climate scientists agree on human-caused warming. Americans conceptualize the issue primarily as environmental (77%) and scientific (68%). Despite 62% feeling a personal responsibility to help, social engagement remains low, with 66% rarely or never discussing the topic with family and friends.

The 2023 wildfire season in Canada, which burned 19 million hectares, highlighted the vulnerability of the forestry industry, which represents 1.7% of Canada's GDP. Climate change is expected to increase the frequency and intensity of fires, potentially leading to a loss of 4 billion dollars in export revenues and 32,000 jobs by the end of the century if no action is taken. The document recommends a coordinated approach involving government and industry to enhance resilience through diversified reforestation, active forest management—including Indigenous-led controlled burning—and the expansion of bioenergy to reduce forest fuel loads.

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 identifies systemic barriers to climate-resilient Indigenous housing in Canada, rooted in colonial policies and exacerbated by funding gaps and capacity constraints. It highlights the disproportionate risk First Nations face from flooding, wildfire, and permafrost thaw, while recommending a shift toward prevention-focused funding, modernized building codes, and the integration of Indigenous Knowledge.

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.

A survey of 1,033 American adults in October 2023 shows that 72% believe global warming is happening, with 58% attributing it primarily to human causes. While 65% of respondents express worry about global warming and many identify specific local risks like power outages and extreme heat, a majority (65%) rarely or never discuss the topic with family and friends. Approximately 10% of respondents report symptoms of anxiety or depression linked to global warming. Despite these concerns, 60% of Americans disagree that it is too late to act, and 63% feel a personal responsibility to help reduce global warming.
