EPA rolls back Biden-era power-plant emissions rules, citing authority limits

The US Environmental Protection Agency announced it will scrap most Biden-era rules limiting emissions from coal- and gas-fired power plants, saying the rules exceeded the agency’s authority and will seek to remove other greenhouse-gas rules for the sector. Officials say the move could save about $310bn and lower energy prices while maintaining safeguards, but environmental groups warn it could worsen public health and climate and expect immediate legal challenges.

Trump EPA rolls back power-plant pollution limits

The Trump-era EPA is rolling back Biden-era limits on carbon dioxide and other pollutants from fossil-fuel power plants, arguing deregulation will improve grid reliability and lower costs; critics warn of higher pollution and health harms, and past AP analyses suggested the rules could have saved tens of thousands of lives and hundreds of billions of dollars annually if kept in place.

Heat Extends Beyond Summer, Across Spring and Fall, Study Finds

Heat Extends Beyond Summer, Across Spring and Fall, Study Finds

A 45-year global analysis (AGU Advances) shows extreme heat seasons have expanded into spring and fall across about half the world since the 1980s, with some regions seeing earlier heat and others later, and a noticeable shift in the seasonality of dangerous heat. NOAA reported this summer (June–August) was the warmest in 132 years in the Lower 48, while August globally set a heat and humidity record. While exact causes remain uncertain, climate change is viewed as the primary driver. The timing shifts raise risk because protections are often centered on summer, leaving communities vulnerable when extreme heat arrives off-season or lingers past expectations.

Himalayas at tipping point as glacier melt threatens South Asia’s lifelines

Himalayas at tipping point as glacier melt threatens South Asia’s lifelines

New research warns the Himalayas are melting much faster than a decade ago, expanding unstable glacial lakes and creating cascading hazards as monitoring gaps persist. India reports 56 glacial lakes rated 'very high risk' and the region’s water sustains around 20% of India’s GDP, while cross-border risks demand coordinated monitoring, early-warning systems, and emissions reductions to protect hundreds of millions who depend on Himalayan rivers.

Heatwaves push Champagne’s alcohol cap higher for this year

Heatwaves push Champagne’s alcohol cap higher for this year

France’s Champagne region will temporarily raise the allowed alcohol content on some bottles to 15% ABV after record heat produced higher grape sugars, affecting only a small share of this year’s harvest (roughly 13.1–13.2% ABV). The 2026 harvest was the earliest on record and climate change is expected to make hotter seasons more common in 10–15 years, with the affected wines heading to shelves no earlier than 2028 after aging.

AMOC May Act as an Ocean Heat Valve, Reframing Earth's Temperature Control

AMOC May Act as an Ocean Heat Valve, Reframing Earth's Temperature Control

A Nature Geoscience study reframes the Atlantic Meridional Overturning Circulation (AMOC) as an 'ocean heat valve' that can either release heat to the atmosphere or trap heat in the ocean, depending on circulation strength. This dynamic could mean that future AMOC weakening might amplify global warming, while past abrupt climate shifts (D–O events) are explained by rapid changes in North Atlantic heat loss. The researchers used climate models to show heat flow acts more like a valve than a simple conveyor, and they caution that warmer, ice-free conditions may alter these mechanisms. More work is needed to determine if multiple stable AMOC states exist or if an irreversible collapse is possible.

One in Nine Migratory Birds Threatened, Sparking Billions for Flyway Protection

One in Nine Migratory Birds Threatened, Sparking Billions for Flyway Protection

A BirdLife International report finds about one in nine migratory birds are threatened with extinction and 45% are in decline, driven by farming intensification, hunting, pollution, invasive species and climate change, with seven species extinct or suspected extinct in the last 150 years. The Nairobi Flyways Declaration mobilizes billions in funding from development banks to protect key habitats and restore migratory routes, building on prior conservation successes such as Australia’s Macquarie Island seabird recovery and China’s coastal mudflat restorations, demonstrating that coordinated action can reverse declines.

Warming World, Widespread Infections: How Climate Change Expands Disease Frontiers

Climate change is reshaping where infections spread: ticks and mosquitoes will carry more diseases into new regions (Lyme, West Nile, malaria, dengue), warming will expand Valley fever in the U.S. Southwest, flooding and drought will compound outbreaks, and rising drought may accelerate antibiotic resistance in soil microbes—necessitating stronger public health measures, better surveillance, and climate mitigation to reduce future risks.

Natural climate feedbacks could add up to 0.4°C warming by 2100, study finds

New research finds natural climate feedbacks from thawing permafrost, intensifying wildfires, and greenhouse gas release from wetlands and lakes could amplify human-caused warming by 20–30% by 2100, adding about 0.2–0.4°C to global temperatures and not fully captured in climate models, potentially pushing projected warming toward 2.6°C with current policies.

NOAA: Summer 2026 Becomes Hottest on Record Across the Contiguous U.S.

NOAA says meteorological summer (June–August) 2026 was the hottest on record for the contiguous United States, averaging 74.4°F (3.0°F above the 20th‑century average). The heat was broad across the Lower 48, with four states—Colorado, Utah, Arizona, and New Mexico—posting their own summer records, and July’s heat dome driving 100°F+ days and persistently hot nights; the period also saw above‑average minimum temperatures in 17 states and contributed to drought strains in the Colorado River Basin, including record low levels at Lake Powell and Lake Mead.

UN Warns We’re Near the 1.5°C Warming Threshold and Urges a Path Back

A UNEP report warns the world is on track to exceed the Paris-aligned 1.5°C warming limit, potentially within just a few years, unless emissions fall immediately and sustainably while adaptation measures are expanded. The document highlights the need for net-negative emissions and scalable carbon capture, plus actions to protect communities from climate impacts, outlining a pathway to return below 1.5°C even as we confront ongoing damages from climate change.

August Ties Global Heat Record as Fossil-Fuel Emissions Push Warming

Copernicus data show August was tied for the hottest month on record, averaging about 1.65°C above pre‑industrial levels with record sea-surface temperatures, driven by fossil-fuel–related warming and El Niño–linked oceans; Europe endured a scorching summer amid heatwaves and drought while global greenhouse gas emissions rose about 0.7% to 54 Gt CO2e in 2025, with the US up 2.2%, China up 0.1%, India down 0.2%, and the EU down 0.2%.

August 2026 Breaks Global Heat and Moisture Records as El Niño Returns

August 2026 was the warmest August and the moistest month on record in ERA5 data, with global temperatures about 1.65°C (2.97°F) above pre-industrial levels and a record 1.08 inches of precipitable water, signaling a wetter, more extreme atmosphere. The warmth and moisture are fed by greenhouse gas emissions and a strong El Niño returning, which is projected to peak in December and could make 2026 the warmest year on record, likely increasing rainfall extremes and contributing to events like major flash floods such as the Grand Canyon incident.
