A new US National Academies of Science report highlights the maturation of climate attribution science while navigating political pressure from the fossil fuel industry.
Summary
The US National Academies of Science recently published a report indicating that climate attribution science has reached a level of maturity that allows researchers to link extreme weather events to anthropogenic climate change with increasing confidence. Using both probabilistic and storyline frameworks, scientists are better equipped than ever to understand how greenhouse gas emissions influence specific weather disasters. While progress is evident, the field faces ongoing challenges, such as a lack of historical weather data in the Global South and difficulties modeling small-scale phenomena. The report advises future improvements in data collection, model resolution, and the incorporation of various human-driven environmental factors. Despite its scientific rigor, the report has become a flashpoint for political controversy; the fossil fuel industry, concerned that this science could be used in litigation to hold them liable for weather-related damages, has reportedly engaged in efforts to undermine the funding and credibility of the institutions involved.
Highlights
The US National Academies of Science (NAS) released a report confirming that climate attribution science—the practice of linking specific weather events to anthropogenic climate change—has become a mature, mainstream field.
Attribution science typically utilizes two primary frameworks: 'probabilistic' analysis, which measures how climate change alters the probability of an event, and 'storyline' analysis, which examines the specific atmospheric drivers of a particular event.
Advancements in statistical methods, machine learning, and computing power have significantly improved the confidence of these assessments compared to a decade ago.
Current limitations include insufficient historical data in the Global South and the inability of climate models to resolve small-scale phenomena like individual thunderstorms or tornadoes effectively.
The report identifies 'compound events'—such as wildfires during extreme droughts—as particularly challenging to attribute accurately due to the complex interaction of variables.
Recommendations for the field include improving data collection methods in data-sparse regions, increasing the resolution of global climate models to the 1-kilometer scale, and incorporating human influences like aerosols and land-use changes.
The report also explores 'extreme event impact attribution' (EEIA), a nascent field that attempts to link specific weather events to measurable economic and social damages using non-linear impact-response functions.
The fossil fuel industry has responded to the growing legitimacy of this science with political pressure, including lobbying to defund the National Academies and threats to researchers, fearing the evidence will be utilized in climate litigation to establish liability for damages.
