6.5 Global methane emissions continue rising; policy response inadequate¶

The International Energy Agency reports that global methane emissions show no signs of declining, indicating insufficient policy action.

Methane 80x more warming than CO₂ over 20 years
Over 100 methane policies identified across 32 jurisdictions, fewer than one-third mandatory
Four countries (India, Indonesia, Thailand, Tanzania) lack identifiable methane policies
India and Indonesia together account for 12%+ of global emissions
Two-thirds of policies show little implementation evidence
Japan's 1998 law with mandatory disclosure cut methane emissions ~40% by 2022

7.5 Boulder and Major Oil Companies Head to Supreme Court Over Climate Damages¶

The U.S. Supreme Court will hear oral arguments on October 5, 2026, in Suncor Energy v. County Commissioners of Boulder County, the first case of its fall term. Oil giants Suncor and ExxonMobil are seeking to block a climate tort suit filed by Boulder, Colorado. The decision could determine the fate of more than two dozen pending climate accountability lawsuits filed by state and local governments against fossil fuel companies over the past nine years.

7.5 Court orders president of the United States to release billions in climate funding for Black communities¶

Federal courts ordered the president of the United States to release over $22 billion in climate and environmental funding for disadvantaged communities. A South Carolina judge in July 2026 required the EPA to resume distributing environmental justice funds, while the D.C. Circuit blocked rescission of nearly $20 billion in Greenhouse Gas Reduction Fund awards that had been terminated in 2023.

7 Study finds 15% of global warming driven by overlooked atmospheric pollutants not covered by climate treaties¶

A new peer-reviewed study published in Science identifies carbon monoxide and non-methane volatile organic compounds as responsible for approximately 15% of human-driven global warming through indirect atmospheric interactions. These pollutants are not included in international climate policy frameworks, despite their significant warming contribution through secondary effects on greenhouse gases.

Carbon monoxide and non-methane volatile organic compounds account for 15% of human-driven global warming
These pollutants do not directly warm the planet but trigger atmospheric reactions that enhance greenhouse gas effects
Currently absent from international climate treaties that form the basis of national emissions pledges
Study led by Ilissa Ocko, senior climate scientist at Spark Climate Solutions and former U.S. State Department climate advisor
Published Thursday in the journal Science

7 Wildfire Severity Escalates Across New England as Drought Fuels Season¶

Wildfire activity has intensified across New England due to severe drought, with Maine's late summer fire activity quadrupling in 2025 and Connecticut's fall wildfires quintupling in 2024. Regional fire seasons have become increasingly severe, compounded by uncertainty over federal personnel reductions and proposed research station closures that could hamper firefighting capability.

Maine wildfire activity quadrupled in 2025 due to drought
Connecticut fall wildfires quintupled in 2024
Massachusetts experienced most active fall fire season in 40 years (2024)
Nova Scotia largest wildfires in recorded history (2023)
Quebec burned over 10 million acres in 2023
