Antarctica's Concordia Station Records a -119.4°F Cold Spell, 16-Year Low

While much of the Northern Hemisphere sweltered, Antarctica's Concordia Station recorded -119.4°F (-84.1°C) on July 18, 2026—the coldest reading there in 16 years and among the lowest reported anywhere on Earth since 2012. Scientists attribute the extreme cold to polar winter, high elevation, and a stable, dry air mass under a persistent high-pressure pattern that created a temperature inversion. Although remarkable, the reading is not a world record—the all-time low remains -128.6°F at Vostok in 1983—and scientists emphasize that such events reflect natural seasonal cycles rather than a broader trend. Concordia, a France-Italy station at about 3,200 meters, is a key site for climate and atmospheric research and a testing ground for long-duration isolation experiments.

Europe’s warming spike: why the continent is heating twice as fast as the world

Europe’s warming spike: why the continent is heating twice as fast as the world

Europe is warming at about twice the global average due to geography (land heats faster than ocean), weather patterns that trap hot air, and the fading cooling effect from sulfur pollution; this summer’s record heatwaves have driven the largest wildfires France and Spain have faced, forcing hundreds of thousands to evacuate as temperatures rise above 100°F and wildfire seasons stretch longer across Europe.

Record-Breaking El Niño Expected to Push Global Temperatures Higher

Record-Breaking El Niño Expected to Push Global Temperatures Higher

Forecast models suggest this El Niño could become the strongest on record, with peak tropical Pacific temperatures about 6.5°F (3.6°C) above average—roughly 1.4°F hotter than the 2015–2016 event—potentially driving global temperatures to as high as 3°F above pre-industrial in 2027. NOAA declared El Niño in June; the peak typically arrives Nov–Feb. If realized, it could bring hotter years and more extreme weather, with researchers warning of up to about $10 trillion in potential economic losses by 2032, though such an unprecedented 6.5°F event remains unverified and uncertain.

Sky-based tweak could blunt El Niño before it begins

A Science Advances modeling study shows that targeted marine cloud brightening over the southeast tropical Pacific could weaken, or even neutralize, developing El Niño events. In simulations of the 1997–1998 and 2015–2016 super El Niños, applying the technique from June through February restored ENSO-neutral conditions, but researchers stress this is a proof-of-concept and not a-ready-for-field approach, noting uncertainties such as potentially faster La Niña onset and other unintended climate effects that require extensive follow-up before any real-world tests.

Space junk forces more satellite dodges, risking climate science data

Space debris in low Earth orbit is increasing, forcing satellites to perform more collision-avoidance maneuvers. Each maneuver uses fuel and can degrade data from climate-observing satellites (Aqua, Terra, Aura), potentially erasing long-running climate records. As debris grows, collision risk rises and insurability drops, pressuring public agencies and private operators to safeguard vital science data.

Top Climate Researchers Rebut DOE’s Claims on Human Warming Fingerprint

A team of climate scientists led by Benjamin Santer rebuts a US Department of Energy report they say misrepresents evidence of humanity’s role in warming, reaffirming the distinctive fingerprint of climate change—tropospheric warming and stratospheric cooling—and warning the DOE analysis should not be used to justify regulatory decisions like the EPA’s endangerment finding.

Antarctic Ice Core Extends Earth's Climate Record to 1.2 Million Years

Europe-wide researchers drilled a 2.8-km Antarctic ice core to produce the longest continuous climate record, about 1.2 million years, showing atmospheric CO2 closely tracking global temperatures across repeated cycles and offering new clues to why ice ages intensified during the Mid-Pleistocene transition. The Beyond EPICA findings—presented at the European Geosciences Union meeting—are early results, not yet peer‑reviewed, with more data to come from the ancient air bubbles trapped in the ice.

El Niño Could Be One of the Strongest on Record, ECMWF Signals

Forecasters say this year’s El Niño could become one of the strongest on record, with ECMWF data showing central Pacific temperatures potentially 3°C above average by year’s end. If confirmed, it could approach or surpass the 1877 and 2015 records and potentially exceed the threshold for a super El Niño. NOAA also expects a strong El Niño to form by July, with a notable chance that 2027 could be the warmest year on record, signaling widespread global impacts on climate, agriculture, water, and economies through late this year and beyond.

Microplastics may be nudging Earth’s climate warmer, new study suggests

A Nature Climate Change study finds microplastics, especially colored pieces, absorb more heat than they reflect, potentially contributing to atmospheric warming; while their impact is not as large as major pollutants, the particles’ near-ubiquitous presence across ecosystems calls for more research into their climate effects.

Soil Fungi Could Trigger Rain by Seeding Clouds with Ice-Nucleating Proteins

A Science Advances study shows soil-dwelling Mortierellaceae fungi secrete water-soluble ice-nucleating proteins that act as cloud seeds, triggering ice formation and rain even at relatively warm temperatures. This bio-precipitation loop links forest soils to atmospheric rainfall, complements bacterial ice-nucleating proteins, and arose via horizontal gene transfer from bacteria. The finding highlights the climate relevance of soil microbes and suggests natural, biodegradable options for cloud seeding while underscoring the rainfall impact of forest conservation.

Ancient ice records reveal stable greenhouse gas levels over 3 million years

New shallow Allan Hills blue-ice cores extend greenhouse-gas records to about 3.1–0.5 million years ago. They show mean CH4 changing little over the period, with CO2 falling by ~20 ppm from 2.9 to 1.2 Ma and then staying stable within ±10 ppm through the mid‑Pleistocene Transition; respiration-corrected samples from 2.8–3.1 Ma yield CO2 of 250 ± 10 ppm, indistinguishable from the early Pleistocene. These results suggest long‑term stability of atmospheric CO2 and CH4 and demonstrate that ice-core gas measurements can be extended into the late Pliocene, providing snapshots of climate during a era of global cooling.
