National Wildlife Federation and other plaintiffs filed an eighth supplemental complaint in their long-standing suit challenging management of hydroelectric dams on the Columbia and Snake Rivers. The plaintiffs alleged that actions taken by the National Marine Fisheries Service, the U.S. Army Corps of Engineers, and the U.S. Bureau of Reclamation in 2020 did not cure defects—including climate change-related defects—identified in a 2016 order of remand by the federal district court for the District of Oregon. Among other things, the plaintiffs alleged that a 2020 biological opinion failed to fully assess the impacts of climate change on salmon, and also failed to consider climate change threats to the Southern Resident killer whale. Under NEPA, the plaintiffs alleged that the analysis of alternatives “does not account for the advancing impacts of climate change, and instead is based on temperatures observed in the region between 1929 and 2008” and that the environmental impact statement then addresses climate change separately from this “counterfactual” scenario in an assessment that “is cursory, truncated, and fails to incorporate credible and available information.” The alleged shortcomings included consideration of climate impacts over a 25-year timeframe despite the analysis of other impacts over 50 years and failure to assess how climate change will compound harms.

Challenges to reviews of the Federal Columbia River Power System's impacts on salmon and steelhead.

An aim to achieve a quantifiable outcome within a given time-frame, set by an institution such as a national government.

Policy instruments are techniques or tools used by governing authorities to promote certain policies in order to achieve predetermined goals. Put simply, instruments are how a government tries to achieve its goals, with this taxonomy being focused on national policy instruments.

Risk is the potential for adverse consequences resulting from the dynamic interplay between (climate-related) hazards, exposure, and vulnerability of affected human or ecological systems.

Groups  of people who are adversely affected by climate change or the response to it

A set of principles, processes, and practices that build economic and political power to shift from an extractive economy to a regenerative economy.

Justice is the ethical and political framework that addresses fairness, including issues of responsibility, rights, and structural inequity.

Renewable energy means all forms of energy produced from renewable sources in a sustainable manner.

Fossil fuel is a generic term for non-renewable energy sources such as coal, fossil gas, and oil (including crude oil, and petroleum products), that can be used for electricity and heat generation. Fossil fuels are hydrocarbons formed from pressurised and heated organic material buried over millions of years.

Molecules in the atmosphere that play a key role in the greenhouse effect by trapping heat radiating from Earth’s surface.

Area of the economy in which actors engage in identical or related activities.

In human systems, the process of adjustment to actual or expected climate change and its effects, in order to moderate harm, increase resilience or exploit beneficial opportunities. In natural systems, the process of adjustment to actual climate change and its effects; human intervention may facilitate adjustment to expected climate change and its effects.

The management and allocation of funds, assets and investments to meet various objectives

People who are less able to respond to the effects of climate change due to having limited financial or physical assets

Direct investments by the governments using public funds. This can be to support climate initiatives or integrate climate into other projects.

Codes and standards are regulatory instruments that specify minimum standards to protect health and safety. This ranges from performance standards, which prescribe outcomes while allowing flexibility to achieve compliance, to the more prescriptive approach of technology-specific standards.

Either money or something of monetary value is transferred between two or more organisations, people or countries.

Conditions that enhance the feasibility of adaptation options. Enabling conditions include finance, technological innovation, strengthening policy instruments, institutional capacity, multi-level governance and changes in human behaviour and lifestyles.

Actions or measures to adapt terrestrial systems to climate change.

Actions or measures to adapt freshwater systems to climate change.

Actions or measures to adapt freshwater, coastal and marine systems to climate change.

Actions to reduce emissions in energy generation and supply.

Extreme weather refers to events where a weather variable exceeds (or falls below) a threshold. Meaning it is significantly different from the average or usual weather pattern.

Social inclusion is the process of improving the terms on which individuals and groups take part in society—improving the ability, opportunity, and dignity of those disadvantaged on the basis of their identity.

Electrical energy generated from mechanical devices driven by flowing fresh water.

Fossil gas, commonly known as natural gas, is a fossil fuel consisting chiefly of methane with smaller amounts of other hydrocarbons and trace gases, found in underground deposits.

Coal is a combustible sedimentary rock formed from carbonised plant matter, rich in carbon and hydrocarbons, and occurring in several main types including hard coal and brown coal.

People with different national or cultural traditions from the dominant population

Social and cultural groups that share collective ancestral ties to the lands and natural resources where they live, occupy or from which they have been displaced

Any compulsory, unrequited payment to the government levied on corporations or individuals. This can be for environmental reasons, such as introducing a Carbon tax to set a price that emitters must pay for the greenhouse gases they emit.

The activities of industries involved in the production, distribution, and sale of energy, including electricity, gas, and renewables.

Activities that involve planning, designing and building infrastructure, residential, and commercial structures.

This sector involves the wholesale and retail selling of goods.

This sector involves activities to move goods and people, alongside the storage of products.

This sector involves activities that impart knowledge and skills to individuals, including formal schooling, vocational training and educational support.

Activities of government agencies and institutions that provide public services, enforce laws and manage public resources.

This sector includes firms and individuals offering specialised expertise in fields such as law, accounting, consulting, science and engineering.

Activities involving the catching, processing, and selling of fish for food, recreation, and industry.

Climate change can have a range of impacts on technological system. Extreme weather events can cause infrastructure failures like power outages or damage to roads and bridges, as well as the impacts from waste following natural disasters. Human activities also cause technological impacts, such as the risks posed by oil spillage and leaks.

Any substance with chemical properties that can cause physical harm to people or damage the environment, including ammonia, carbon monoxide, phosphine, chlorine, arsenic, cadmium, mercury, pesticides, dioxins, microplastics, benzene, asbestos, aflatoxins, fluoride, methanol, and toxins from marine sources.

Climate change impacts our society by disrupting the natural, economic and social systems we depend on. Physical hazards and underlying vulnerabilities can lead to increased resource competition for food and water, which can heighten the risk of conflict.
