The Union of Concerned Scientists analysis finds that 48% of the rise in fire-danger conditions in western North America since 1901 and 37% of the cumulative burned forest area since 1986 are attributable to emissions from the 88 largest fossil fuel companies and cement manufacturers. In Arizona, over 10,000 wildfires burned nearly 2.5 million acres between 2017 and 2021, with the 2020 Bighorn Fire alone costing over $36 million. The document argues for holding these companies accountable and urges state governments to implement policies for forest health, community safety, and equitable resilience investments.

The document argues that major carbon producers are responsible for a significant portion of the increasing wildfire risk in western North America. It attributes 48% of the rise in fire-danger conditions since 1901 and 37% of the cumulative burned forest area since 1986 to emissions from 88 major fossil fuel and cement companies. In California, wildfires between 2017 and 2021 caused over $21 billion in economic damages and released an average of 53 million metric tons of CO2-equivalent annually. The report calls for corporate accountability, legal access to justice, and state-level policies to reduce emissions, improve forest health, and protect vulnerable communities.

The Union of Concerned Scientists analysis attributes 48 percent of the rise in fire-danger conditions in western North America since 1901 and 37 percent of the cumulative burned forest area since 1986 to emissions from the 88 largest fossil fuel and cement companies. In Colorado, over 5,000 wildfires burned more than 1 million acres between 2017 and 2021, including the record-breaking 2020 Cameron Peak Fire. The document argues that these companies should be held accountable for the costs of climate change and recommends that state governments implement policies to reduce human-ignited fires, increase forest health resources, and protect vulnerable communities.

The Union of Concerned Scientists finds that 37% of the cumulative burned forest area in western North America since 1986 is attributable to emissions from 88 of the world's largest carbon producers. The report links these emissions to a rise in vapor pressure deficit (VPD), which increases atmospheric 'thirst' and dries out vegetation, thereby amplifying wildfire risk. It argues that these corporations should be held legally and financially accountable for climate damages, including the costs of wildfire suppression and recovery.

The Union of Concerned Scientists analysis attributes 48 percent of the rise in fire-danger conditions in western North America since 1901 and 37 percent of the cumulative burned forest area since 1986 to emissions from the 88 largest fossil fuel companies and cement manufacturers. In Oregon, over 10,000 wildfires burned nearly 3.7 million acres between 2017 and 2022, including the 2021 Bootleg Fire which burned more than 400,000 acres. The document argues that these companies should be held accountable for the costs of climate change and wildfire resilience, and recommends state-level policies to reduce human-ignited fires, improve forest health, and protect vulnerable communities.

The Union of Concerned Scientists analysis finds that 48% of the rise in fire-danger conditions in western North America since 1901 and 37% of the cumulative burned forest area since 1986 are attributable to emissions from the 88 largest fossil fuel companies and cement manufacturers. In Washington state, nearly 8,000 wildfires burned over 2.5 million acres between 2017 and 2022. The document argues for holding these companies accountable and urges state governments to implement resilience-building policies, including reducing human-ignited fires, improving forest health, and protecting vulnerable communities.

The project focuses on the intersection of human and natural systems in western North America, specifically addressing risks from weather extremes, water scarcity, and food security. It aims to strengthen adaptive management by promoting the exchange of climate information between scientists and policymakers, utilizing tools like the Binational Climate Summary and GIS analysis of tropical cyclones. Phase I findings indicate that while water managers are interested in seasonal forecasts, their utility is hindered by issues with spatial and temporal resolution and a lack of inter-agency cooperation. The document also notes that agriculture consumes 70% to 90% of the region's water and that population growth is increasing water and energy demands.
