Tree rings reveal climate impacts of the Paektu (Changbaishan) Volcano’s “Millennium Eruption”
The “Millennium Eruption” of the Paektu Volcano on the border of China and North Korea lowered temperatures and changed precipitation patterns across Asia, new research reveals. Researchers used tree rings, historical records and comparisons between ice core and petrogeochemical data to determine climate impacts and revise the date of the eruption from 946 to 945 CE.

Climate change, fires and deforestation have shrunk carbon stores in the West
The total mass of living trees and plants declined by up to 25% across the western United States between 2005 and 2019, most likely due to fire, drought and deforestation. During that time, the Pacific Northwest had the greatest total live carbon, or living plant matter, while the Southwest had the least. [Earth’s Future research][Cary Institute press release]  

Small hydropower plants need to plan for drought, economic instability
Climate change is expected to increase the frequency of droughts in some parts of the world. New research finds that small hydropower plants should account for variable water levels and socio-economic factors to be reliable and financially viable in the future. [Water Resources Research research] 

AI can help distinguish between earthquakes and explosions
Earthquakes and explosions both send acoustic waves through the ground and the air, making it hard for detection stations to differentiate what caused the waves. A new AI model uses inputs from both seismic (ground-based) and infrasound (air-based) waves to determine the source of disturbances on the Korean Peninsula. [Geophysical Research Letters research] 

Woody plants’ ranges across the Great Plains will shift as the climate warms
The spread of trees and other woody plants into grasslands in Texas, Oklahoma and Kansas limits the amount of land available for cattle and reduces the region’s water supply. As the climate continues to warm, honey mesquite will spread farther north and east into the Great Plains, while the ranges of other woody plants in the region will decrease, new research finds.

Weather “whiplash” taxes California’s water system
California relies on reservoirs and dams to generate power, fuel agriculture and feed waterways. Strong atmospheric river storms can end droughts, but rapid increases in reservoir water levels threaten dam infrastructure and reduce power generation. Future infrastructure projects should focus on creating more resilient reservoirs and recharging groundwater, according to a new study. [Water Resources Research research] 

Space launches spawn noctilucent summer clouds in the Arctic
Space traffic take-offs release large water vapor plumes. Within days, winds carry this vapor into the Arctic Circle, new research finds. In July, when the upper atmosphere is coldest, the water vapor can form noctilucent or “night shining” clouds 50 miles above the Earth. [Earth and Space Science research] 

A new look at old moon data: Apollo-era moonquakes more common than previously thought
New analysis of an archive of messy lunar quake observations, collected at Apollo landing sites between 1969 and 1977, finds that the Moon had 2.6 times more quakes during that period than previously known. The moon’s northern hemisphere was also more seismically active than its southern hemisphere, where NASA plans to land its Artemis III mission. [JGR Planets research] 

Cosmic electron beams could interfere with measurements of Europa’s ocean
Powerful electron beams discovered near Europa by the Juno spacecraft may affect the space environment surrounding the moon, which could alter how scientists measure Europa’s subsurface ocean. [Geophysical Research Letters research] 

Dim and slow meteors can still generate luminous trains
Meteors leave behind self-illuminating “trains” as they hurtle through the atmosphere. New observations of approximately 7,000 meteors reveal that meteor trains are more common than previously thought, and that slower-moving meteors leave trains just as frequently as faster-moving meteors.

Canadian wildfire smoke sent itself to US East Coast
Intense wildfires can “make their own weather,” resulting in unusual weather patterns. In 2023, wildfires in Canada shot smoke to the U.S. East Coast because aerosols in the smoke intensified a cyclone while helping it stand still. That stagnant cyclone then sent the smoke southward.

Many houses — especially second homes — remain uninsured despite flood risk
More than two-thirds of properties at risk of flooding are uninsured, lowering their climate resiliency. Following a flood in a county, the rate of insurance adoption rises 7% within a year, but drops after that, a new study finds. Relying on households to close this “insurance gap” may not work, the authors suggest, especially where flood-exposed houses are not primary residences. [Earth’s Future research]

Glaciers in Peru, Bolivia fastest-shrinking in the Andes
Glaciers atop the Andes in South America are shrinking quickly, and new research finds those in the tropical Andes — in Peru and Bolivia — have lost the most mass and shrunk the most quickly since the Little Ice Age (1400 – 1850) of any Andean glaciers. [Geophysical Research Letters research]

Climate, cropland and population growth threaten orchids in China
China is home to more than 1,500 species of orchids, which can be highly vulnerable to climate change and anthropogenic influences. Of these, about 43% are threatened.

Louisiana’s 2023 “dire” water crisis: why it happened and could hit again
In the summer and fall of 2023, Louisiana faced two water crises: a severe drought and such low water levels in the Mississippi River that saltwater began to creep up the channel, threatening already stressed drinking water supplies. High evaporation rates were mostly responsible for the conditions, a new study reveals, with low precipitation playing a secondary role. [LSU press release][Geophysical Research Letters research]

Top 20% of Shanxi coal mines emit half of region’s methane
The Shanxi province is China’s most prolific coal producer; coal mining is one of the world’s top methane sources. Coal producers in the region emitted 1.2 million tons of methane each year between 2021-2023, with about half of all emissions coming from just 20% of the facilities, a new study finds. The results challenge previous, lower estimates. [Geophysical Research Letters research]

Peat patches could expand, store more carbon as Arctic warms
Rapid warming in the Arctic is thawing permafrost, which can release vast volumes of carbon. But warmer temperatures may also prompt peat patches to grow, storing carbon as they do, a new study suggests. Peatlands growth might partially offset carbon release from permafrost thaw.

Acidity, heat, and deoxygenation pose triple threat to oceans
Ocean acidification, warming and deoxygenation events can damage ocean ecosystems and structures on their own. When all three hit at once, the impacts are amplified, reducing habitable space. About 20% of the world’s oceans — mostly in the North Pacific — are vulnerable to this triple threat. Triple-threat events have become larger, more intense, and longer-lived since the 1960s.

Rockies and Ethiopian Highlands most vulnerable to high elevation drying trend
The air and soil of most mountain ranges worldwide have dried significantly since the 1970s due to warming temperatures and shifting precipitation patterns driven by climate change. The Rocky Mountains and Ethiopian Highlands have seen the most critical drying, with both atmospheric and soil aridity increasing by 13% across all elevation gradients. [Earth’s Future research]

More frequent winter warm spells threaten snowpack in western US and Canada
In western North American, warms spells —three or more days of unseasonably warm temperature highs — account for 49% of snow loss in winter. The loss occurs during a small window of time, only 0.6 days on average. But climate change is projected to make winter warm spell three times more frequent in humid regions, increasing snow loss by 147%, and stressing water supplies for many communities. [Water Resources Research]

Low carbon emission pathway halves future anthropogenic mercury pollution
Burning fossil fuels, especially coal, releases mercury, a toxin with severe health consequences for people and wildlife. High carbon emissions scenarios release mercury at present-day levels through 2060. On the low emissions pathway, the mercury peak will come at 2030 and decline faster. The cost of delay is compounded by re-emission of mercury deposited on land and in oceans. [Earth’s Future research]

Nature-based carbon removal strategies most popular, least effective
To achieve net zero carbon, countries will need to remove carbon dioxide that has already been released to the atmosphere. German researchers assessed 14 carbon removal options for technological, legal and institutional readiness, economic and environmental impact, and public perception. Removal potential is small compared to the size of the problem, underlining the need to reel back emissions now.  [Earth’s Future research]

Streams lose year-round flow in California
A survey of stream gauges in dry regions of California found 13% of 158 minimally-disturbed streams had lost perennial flow — a sign of the drying influence of a warming climate. Streams burdened by human development are generally drying faster but, in some cases, regulation has made water flow perennially in previously ephemeral streams. [Water Resources Research]

Landslides mark “recent” tectonic activity on Mars
In western Arabia Terra, Mars, a long fault system shows signs of repeated activity during the last 2 billion years, a time when the Red Planet was thought to have little tectonic activity. Four landslides of different ages tumble to the crater floor, triggered by tectonic processes that shorten the crust, thrusting up a chunk of the surface and creating a scarp up to 700 meters high. The total displacement would require about 3,300 marsquakes of the magnitude observed in the modern era, the researchers calculated. [Geophysical Research Letters research]

Farming the seas wisely has ecological benefits
Mariculture employing seaweed rafts, deep fish cages and shellfish rafts, hanging cages, and bottom sowing could turn ecological burdens into benefits with strategic selection of species, technology and location. Case studies off the coast of China, the largest mariculture producer, demonstrate combining approaches can mitigate water contamination from intensive fish farming – and feed a lot of people.
