8.5 UN report: world cannot meet 1.5°C warming limit with current commitments¶

The UN declared in September 2026 that the world cannot meet the 1.5°C warming target under current policies. Global CO₂ emissions must fall to zero by 2031 to stay within the remaining carbon budget of 130 billion tonnes—a pathway the UN describes as impractical but unavoidable.

Remaining carbon budget: 130 billion tonnes CO₂ from 2026 onward
Current emissions: ~40 billion tonnes/year, rising
Budget exhaustion timeline: ~3 years at current rates
Current trajectory: 2.6°C warming by century's end
Human-induced warming already at ~1.4°C

8 President of the United States eliminates climate rules for coal and gas power plants¶

On September 14, the president of the United States's EPA repealed Obama-era emissions limits on coal and natural gas power plants, eliminating $300 billion in compliance costs. The agency also proposed rules to prevent future administrations from re-regulating power-sector emissions.

Estimated cost elimination: $300+ billion for utilities
Affects coal plants (existing) and natural gas plants (new)
Repeals rules requiring emission cuts beginning in 2030s
Proposes permanent ban on future federal re-regulation
Power plants: second-largest U.S. source of CO₂ emissions

8 Global Oceans Break Heat Records with 100 Consecutive Days of Peak Temperatures¶

Global ocean surface temperatures outside polar regions sustained record highs for 100 consecutive days from June 2 to September 10, 2026, with the peak of 21.10°C reached on August 22. Climate change and El Niño are driving the unprecedented warming, affecting marine ecosystems and food security worldwide.

100 consecutive days of record sea surface temperatures (June 2 – September 10, 2026)
Peak temperature: 21.10°C (69.98°F) on August 22; August 22–27 average: 21.18°C (70.12°F)
Ocean absorbed 23 zettajoules of energy in 2025, a 43% increase from 16 zettajoules in 2024
Over 90% of excess heat from greenhouse gases goes into the ocean

7.5 Asia Mobilizes for Record-Strength El Niño Amid Climate Risks¶

Asian governments are mobilizing preparations for a record-strength El Niño expected to intensify from late 2026 into 2027, driven by exceptionally warm Pacific waters and human-driven climate change. The World Food Programme projects 50 million people will be pushed into acute hunger amid droughts, floods, typhoons, and wildfires.

50 million people projected to face acute hunger
Very strong El Niño intensity expected late 2026 into 2027
Hong Kong recorded hottest day on record August 9; revised workplace heat policies
China developing climate risk maps
Impacts include droughts, wildfires, typhoons, floods across hundreds of millions

7.5 Tapanuli Orangutans Face Existential Threats Without Recovery Strategy¶

Tapanuli orangutans, the world's rarest great ape with only 716 individuals remaining, face mounting threats including mining expansion, landslides, and severe fire risk with no coordinated recovery strategy. A 2025 cyclone killed approximately 58 individuals and damaged over 8,300 hectares of habitat.

7 Microplastics in soil act as vectors for toxins and pollutants¶

A five-year E.U.-funded study found microplastics in soil function as vectors delivering pollutants, pesticides, bacteria, and antibiotic-resistant genes. Testing 227 agricultural fields across 11 European countries revealed microplastics present in all fields, forming toxic 'plastisphere' microbial habitats on their surfaces.

227 agricultural fields tested across 11 European countries; microplastics found in all
Microplastics create 'plastisphere' microbial habitats concentrating pollutants and bacteria
Smaller microplastics adsorb more pollutants, microbes, and antibiotic-resistant genes
Microplastic contamination disrupts earthworms and soil nutrient cycles
22 peer-reviewed studies produced; biodegradable plastics degrade into microplastics
