Defenders of Wildlife and Healthy Gulf filed a federal lawsuit in the Southern District of Mississippi claiming that the U.S. Army Corps of Engineers and the Mississippi River Commission were failing to comply with the Endangered Species Act (ESA) in connection with its operation of the Bonnet Carré Spillway, a flood-control mechanism on the lower Mississippi River. The plaintiffs alleged that the agencies had never completed formal or informal consultation under the ESA to consider the impact of diversions on nine threatened and endangered species that inhabit the bodies of water into which the spillway diverts water to reduce flooding in New Orleans. The complaint states: “As more extreme storms and varied weather increase the number and intensity of floods in the lower Mississippi River valley region, it is likely that the Spillway will be opened more frequently and for increasingly longer duration in the future. This in turn will increase the frequency and duration that imperiled species and habitats are subjected to Spillway water pollutants and other impacts.”

Lawsuit alleging that consultation under the Endangered Species Act was required for the ongoing operations of the Bonnet Carré Spillway.

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.

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.

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.

Slow onset events evolve gradually from incremental changes over many years or from increased frequency or intensity of recurring events. As defined in the Cancun Adaptation Framework (2010), slow onset events include risks and impacts from rising temperatures, desertification, biodiversity loss, land and forest degradation, glacial retreat, ocean acidification, sea level rise, and salinization.
