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 December 2022 survey finds that 70% of Americans believe global warming is happening, with 58% attributing it primarily to human activity. While 64% express worry and 63% feel a personal responsibility to help, social engagement remains low, as 63% rarely or never discuss the issue with family and friends. A majority of respondents perceive global warming as already affecting U.S. weather and various environmental problems, though only 14% believe it is too late to take action.

Climate Central's analysis of 246 U.S. locations since 1970 reveals that winter is the fastest warming season for 74% of these sites, particularly in the Northeast and Great Lakes regions. While winter warming disrupts snowfall and water supplies, other regions experience faster warming in different seasons: western U.S. locations often see faster spring and fall warming, while parts of Washington, Oregon, Texas, and Florida experience the most rapid summer warming. These shifts contribute to increased wildfire risks, altered agricultural cycles, and higher energy demands for cooling.

The author uses recent heatwaves and wildfires in Europe to illustrate how climate change exacerbates air pollution and health issues. The text details a feedback loop where petrochemical production leads to plastic pollution, which in turn releases methane and ethylene, harms soil carbon absorption, and disrupts marine food production. It concludes by highlighting the need for holistic legislation, citing the European Union's decarbonization strategy, a proposed UN global treaty on plastic waste, and updates to the Canadian Environmental Protection Act.

Summer 2022 was the third hottest on record for the contiguous U.S., with significant influence from climate change on both daytime and nighttime temperatures. Using the Climate Shift Index, the analysis shows that nearly half of the contiguous U.S. experienced 15 or more days where average temperatures were at least twice as likely due to climate change. The period was also marked by extreme precipitation in Missouri and Kentucky, widespread wildfires burning over 6.7 million acres, and severe drought affecting 94% of Hawaii and 85 consecutive weeks in Puerto Rico.

The Canadian Association of Physicians for the Environment has issued a formal letter to the Union of BC Municipalities (UBCM) protesting the acceptance of sponsorships from fossil fuel entities. The physicians argue that such partnerships create a conflict of interest and undermine municipal climate action, particularly given the severe health and economic impacts of climate-induced disasters in British Columbia and globally.

Between 2000 and 2021, the U.S. experienced 1,542 major weather-related power outages, with 83% of all reported major outages attributed to weather. The average annual number of these events increased by approximately 78% in the 2011-2021 decade compared to 2000-2010. Severe weather, winter weather, and tropical cyclones were the primary drivers, with the Southeast, Midwest, and Northeast regions most affected. To address these vulnerabilities, the document suggests solutions such as microgrids, smart grid technologies, grid hardening, and bidirectional charging for electric vehicles.

Climate Central's analysis of U.S. power outage data from 2000-2021 reveals a significant increase in large-scale disruptions, with 83% of major outages attributed to weather-related events. The report highlights that the frequency of major outages rose by 64% between 2011-2021 compared to 2000-2010, driven by severe weather, winter storms, hurricanes, extreme heat, and wildfires. It emphasizes the vulnerability of aging infrastructure and the compounding effects of climate change, which simultaneously increases electricity demand for cooling while reducing the capacity of power plants due to water shortages. The report identifies the Southeast as the region with the highest number of outages and notes specific recent surges in Texas, California, and Michigan.

The policy brief examines the impact of high-severity wildfires on the U.S. forest carbon sink, noting that forests in several Western states have become net carbon emitters. It advocates for scaling up 'fuel load treatments'—such as prescribed burns and mechanical removal of biomass—to mitigate wildfire risk and suggests developing markets for thinned biomass (e.g., biochar, green hydrogen) to fund these efforts and reduce emissions. The brief calls for federal policy support via the 2023 Farm Bill to increase research, support rural and Tribal communities, and incentivize innovative wood products.

The report finds that while a majority of Americans (72%) believe global warming is happening and 56% attribute it to human causes, there is a significant gap in understanding the strength of the scientific consensus. Public concern is high, with 64% feeling worried and many reporting personal experiences with climate impacts, yet social discussion of the topic remains low, with 67% rarely or never discussing it with family and friends.

The Canadian Association of Physicians for the Environment (CAPE) submitted recommendations for Canada's National Adaptation Strategy (NAS) in July 2022. The submission argues that the NAS must explicitly address the intersection of climate change and both physical and mental health, noting that physicians are already observing increased asthma and anxiety linked to wildfires and extreme heat. CAPE highlights that extreme heat disproportionately affects vulnerable populations, including those in poverty, racialized communities, and older individuals. The organization calls for the NAS to include specific outcomes and targets, protect nature for its own sake, and prioritize natural infrastructure—such as urban tree canopies—to mitigate heat and improve public health. Additionally, CAPE emphasizes the need to harden health infrastructure to ensure hospitals remain functional and serve as community safe havens during extreme weather events.

Wildfires in the western United States are increasing in size and severity due to climate change and historical fire suppression, posing significant risks to water resources. High-severity fires destroy vegetation and alter soil chemistry, leading to increased streamflow, flooding, and the contamination of drinking water with sediments, toxins, and carcinogens. The document advocates for a combination of emissions reductions, active forest management—including prescribed and Indigenous cultural burns—and investments in climate-resilient water infrastructure to mitigate these threats.

The document outlines how climate change impacts mental health through direct, indirect, and vicarious risks. It provides data on depression and PTSD following disasters like hurricanes, highlights widespread climate anxiety among Americans and global youth, and discusses strategies for building individual and community resilience.

The Environmental and Energy Study Institute (EESI) hosted a briefing series titled 'Living with Climate Change' to address community preparation for polar vortices, sea level rise, wildfires, and extreme heat. A specific focus was placed on the polar vortex, noting that climate change is expected to affect the frequency and severity of these events. The document highlights the necessity of adaptation strategies for the energy grid and home energy efficiency to prevent deadly power losses, citing 246 deaths during the 2021 Texas polar vortex freeze.

A survey of 1,018 American adults in April 2022 reveals that while 72% believe global warming is happening and 56% attribute it to human causes, there is a significant gap in understanding the strength of scientific consensus. A majority of respondents (64%) are worried about global warming, and many perceive it as already affecting U.S. weather and local environmental risks, such as electricity power outages and water pollution. However, social engagement remains low, with 67% rarely or never discussing the topic with family and friends.

The project aims to establish a comprehensive multi-risk early warning system in Togo, targeting 100% of the population (approximately 8.28 million direct beneficiaries). It addresses critical gaps in hydrometeorological monitoring, data processing, and dissemination. The initiative is structured around four components: institutional development, operational capacity improvement for monitoring agencies, infrastructure modernization (including low-cost automated weather stations), and the creation of a sustainable financial framework involving public-private partnerships. The project seeks $10 million in GCF grants with an equal amount in co-financing for a total cost of $20 million over four years.

The document explains 'event attribution' as a scientific method to determine how much human-induced climate change affects the probability and intensity of specific weather extremes. It provides a detailed breakdown of how climate change influences heatwaves, floods, tropical cyclones, snowfalls, droughts, and wildfires, while cautioning against oversimplifying these events as having a single cause. The guide emphasizes that while some trends (like heatwaves) are globally certain, others (like floods or droughts) vary by region and are influenced by local human factors such as land use and water management.

The Kingdom of Eswatini's Initial Adaptation Communication (AdCom) identifies key climate hazards such as droughts, floods, and heatwaves, and details national efforts to mitigate these impacts through flood control, irrigation, and climate-proofed infrastructure. It highlights the role of the National Climate Change Policy (2016) and the National Climate Change Strategy and Action Plan (2015-2020) in guiding adaptation actions involving government, NGOs, and the private sector.

The author contends that the perceived conflict between the economy and the environment is false, asserting that climate inaction is destructive to economic growth. Citing the 2021 floods and mudslides in British Columbia, the text highlights the massive financial losses caused by disrupted supply chains and infrastructure failure. It notes that climate-related catastrophes have cost Canada approximately 5% to 6% of its annual GDP growth since 2010. The document calls for urgent investment in future-proof, carbon-neutral infrastructure and the modernization of outdated climate risk data to protect the national economy.
