They have known for decades that climate change is altering the frequency and intensity of several types of extreme weather events, including hurricanes, heat waves and extreme rainfall.</p><p>But the field of attribution science allows them to move beyond detecting broad trends to investigating individual events -- what the authors call extreme event attribution (EEA) -- which can provide vital information to policymakers.</p><p>EEA studies compare an event&#x27;s characteristics, such as its probability and intensity in the current climate, to a &quot;counterfactual&quot; world without human-caused emissions.</p><p>The authors found that overall, EEA capabilities have improved markedly over the past decade, thanks to advances in understanding physical drivers of events, expanded observational data from satellites and radar, new statistical techniques and better models.</p><p>But the gains are uneven. Confidence estimates are also lower for underdeveloped parts of the world, where a lack of consistent, long-term records limits attribution science&#x27;s reach.</p><p>The authors called for a common framework for attribution studies, as there can be &quot;confusion among the public and other stakeholders when studies of the same event produce different results.&quot;</p><div><br/></div><div><strong>SOWING DOUBT </strong></div><div><br/></div><p>Still, the results are likely to boost the multitude of lawsuits working their way through courts across the country.</p><p>Oregon&#x27;s Multnomah County, for example, is suing fossil fuel giants for more than $51 billion over pollution that fueled a deadly 2021 heat dome in the Pacific Northwest, during which hundreds died.</p><p>Ahead of the report&#x27;s publication, Republican lawmakers sought to cast doubt on the authors&#x27; work, sending a letter in April to the president of NASEM alleging bias and demanding details on the authors&#x27; professional ties.</p><p>Energy In Depth, an oil industry blog, singled out Delta Merner, a scientist with the nonprofit Union of Concerned Scientists, for criticism in a January 2, 2025 post, and she left the panel the same day.</p><p>Hurrell said he was aware of the &quot;chatter,&quot; but added: &quot;I can honestly tell you that in no way did any of that outside chatter affect my work as chair of the committee, nor did it affect the final report that was produced.&quot;</p><p>At the federal level, the Trump administration has sued Democratic-led states seeking climate damages from oil and gas majors, and has sought to strike down state &quot;Climate Superfund&quot; laws requiring polluters to pay for the consequences.</p><p>Republicans in Congress, meanwhile, have introduced the &quot;Stop Climate Shakedowns Act,&quot; a bill that would block climate damage lawsuits from proceeding in court -- a move critics call a de facto immunity shield for fossil fuel companies.</p><div><br/></div><div><strong>© Agence France-Presse</strong></div><div><strong><br/></strong></div><div><strong>RELATED VIDEOS</strong></div><div><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/CWCtj7Nskg0?&amp;wmode=opaque&amp;rel=0" frameBorder="0" allowfullscreen="" class="fr-draggable"></iframe></span><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/KQz2jVGauHo?&amp;wmode=opaque&amp;rel=0" frameBorder="0" allowfullscreen="" class="fr-draggable"></iframe></span><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/y19WEesgy2k?&amp;wmode=opaque&amp;rel=0" frameBorder="0" allowfullscreen="" class="fr-draggable"></iframe></span><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/F6U91cXoNuo?&amp;wmode=opaque&amp;rel=0" frameBorder="0" allowfullscreen="" class="fr-draggable"></iframe></span><br/></div>
