Humpback whale sightings off Western Australia fell 60% during this year's migration
Researchers also recorded fewer calves and more entanglements; Olaf Meynecke says early sea ice melt and less food may be factors.

Coast redwood basal resprouting rose with fire damage after California's 2020 CZU fire, 77-tree study
In a field study of 77 redwoods burned in the 2020 CZU Lightning Complex, basal resprouting did not decline with greater fire damage but increased. Drier sites showed less.
Utrecht University model: groundwater recovers fast after drought at 57% of locations, 26% unstable
A global simulation for 1960–2019 sorted land by groundwater recovery after drought: 57% resilient, 15% vulnerable, 26% unstable, where repeated droughts cut recovery capacity.
Greenland: two unstable slopes of 400 and 30 million m³ found in the Uummannaq Fjord system
Researchers documented active deformation of two newly identified slopes in West Greenland; simulations show a collapse of the larger one would send a tsunami through the whole fjord system.
PKNU study: South Korea's flying squid catch may fall to zero by the 2040s
Researchers at Pukyong National University link the decline of Todarodes pacificus to marine heat waves. The current catch is one-sixteenth of the 2002 level.
KIT and EEW prepare NECOC 2.0 to turn waste-plant CO₂ into solid carbon, €5 million funded
The project will test the full chain on CO₂ from a real flue gas stream at EEW's Eschbach site; earlier, the steps were shown in a 2020 experimental unit.
IIT Madras and Gauhati University use a climate network to date monsoon onset at each location
Researchers define large-scale monsoon onset at a location as its joining the largest cluster of rainfall onsets, which separates the monsoon from short local rain spells.
Weddell Sea: dissolved organic matter stays unchanged during dense-water formation, 178 samples
Samples from 38 stations show that the molecular composition of dissolved organic matter in the Weddell Sea is set before dense shelf water mixes with warmer off-shelf water.
Korean team ties East Sea flying squid collapse to marine heatwaves; models give zero catch by 2040s
Researchers at Pukyong National University linked the collapse of the Japanese flying squid fishery in the East Sea to warming and heatwaves. Their projections show zero catch by the 2040s.
Saharan dust shifted bacterial communities in Amazon air and tripled endotoxin at the ATTO tower
During a five-day dust intrusion, bacteria from drylands and marine environments replaced local ones at 42 and 323 m, while fungi stayed unchanged, the authors report.
Review: spaceborne HSRL lidar on two satellites measures plankton layers below the ocean surface
A review in The Innovation says high-spectral-resolution lidar on China's DQ-1 and Europe's EarthCARE replaces assumptions with measurement of subsurface plankton.
Amundsen Sea cores: West Antarctic outlet glaciers lost their basins in warm periods of the last 800 kyr
Seabed sediments from the Amundsen Sea show that glacial debris from the main West Antarctic outlet glaciers almost vanished in all earlier warm periods, the authors report.
Sediment data from Zaragoza tie post-impact climate swings to orbital cycles, not Deccan volcanism
University of Zaragoza researchers compared marine sediments spanning about 750,000 years around the impact 66 million years ago. Later carbon-cycle events coincide with orbital eccentricity cycles.
Wildfire traces in two Chinese basins show uneven fire activity during the PETM warming
Polycyclic aromatic hydrocarbons in 40 sediment samples show fire peaks at different times in each basin, which weakens the case for global peat burning.
Max Planck Institute: Southern Ocean vented CO2 during Eocene warmth, foraminifera shells show
Nitrogen isotopes in fossil plankton shells show Southern Ocean algae used about 40% less nutrients at the Eocene peak; a model links this to at least half of the CO2 rise.
Novamont and Sila unveil Nutrilox feed additives: up to 33% lower ruminant methane intensity in trials
Novamont (Versalis, Eni) and Sila introduced five microencapsulated feed additives at EuroTier; in vivo studies at the University of Bologna showed up to 33% lower methane intensity.
NaTran and HyLigh test a 12 m hydrogen airship for methane leak detection on gas pipelines
The remotely piloted HyLighter will fly over up to 1,600 km of pipelines between Nantes and Quimper until 13 November 2026 in a trial campaign.
Rutgers study of 893,212 Medicaid pairs links wildfire smoke in pregnancy to higher autism diagnosis rate
An observational study in JAMA Pediatrics found that each 0.75 µg/m³ rise in wildfire PM2.5 during pregnancy was linked to a 30% higher risk of a later autism diagnosis.
Siberia 2021 fires: radiative power nearly 9 times average, soil dryness linked to heat
Satellite data for 2004–2024 show summer 2021 was among Siberia's worst fire seasons; the authors link extreme heat to a soil moisture feedback, not circulation alone.
UC Davis: melioidosis antibodies persist for years after infection, complicating tests as bacterium spreads in the U.S.
A Thai cohort study in The Lancet Microbe found antibodies to Burkholderia pseudomallei persist for years, so a positive test may reflect past infection. This matters for surveillance in new regions.
