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. Most threatened species are in southwestern, central, and northwestern China, with cropland expansion and increases in population density driving the threats, according to a new study.

Achieving carbon neutrality would stop marine heatwaves in their tracks
Marine heatwaves can cause acute environmental damage and chip away at species’ ability to survive. They’ve become more frequent, widespread and severe. But achieving carbon neutrality would halt that growth, dramatically limiting the area of ocean exposed to “permanent” heatwave conditions, according to new research. [Earth’s Future research]

Summit of unique Tanzanian volcano is sinking
Ol Doinyo Lengai is an active volcano in Tanzania, neighbor to Mount Kilimanjaro. Its summit has been sinking for at least a decade, new satellite-based analysis reports.

Almost all the water from Tonga eruption remains in stratosphere
Nearly all of the water that the 2022 Hunga Tonga eruption injected into the atmosphere was still in the stratosphere and mesosphere as of November 2023, a new study reports. The water vapor could impact temperature and ozone. [JGR Atmospheres research]

Urban heat islands speed up winds in city “canopy”
A city’s structures can slow down wind; with buildings and other structures, a city’s surface is rough. But the heat island effect can counteract that slowing. A new study models why that happens in the megacity Shanghai and finds heating can increase the wind speed in the urban “canopy” by about 30%.

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.

Pikas create bare patches, warming permafrost in Tibetan Plateau
Pikas — the tiny, cute mammals often heard squeaking in alpine boulder fields — create bare patches of ground as they burrow. In shallow Tibetan soils with permafrost, that loss of vegetation led to a warming of 0.36 degrees Celsius. It’s a previously unexplored pathway for permafrost warming.

Heatwaves during El Niño travel farther and more slowly
Heatwaves that occur under El Niño conditions tend to be more frequent, be more persistent, travel farther, and move more slowly than heatwaves under La Niña conditions, according to a new study that examined heatwaves from 1961 to 2020. The pattern held over all continents but was strongest in the tropics. [Geophysical Research Letters research]

Featured Research

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. [AGU Advances research]

Urban wetlands could help save this historic Chilean city from flooding
Valdivia, near the Chilean coast, is a city of wetlands; they cover nearly a quarter of its area. The spot was home to one of the Americas’ oldest cultures, which used the wetlands to flourish. Today, the city’s 166,000 inhabitants could lean on the wetlands once more — this time to alleviate flooding from climate change. But development threatens wetland loss. [Earth’s Future research]

Climate change cuts critical rice production in India’s Uttar Pradesh
India has the largest area of rice agriculture of any country, but hotter temperatures and shorter growing seasons will curb rice production by up to 20% by the end of the century in Uttar Pradesh, the most populous Indian state, a new study finds. Increases in rainfall may reduce the need for irrigation, but climate change will lower rice yields overall. [Earth’s Future research]

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.

Auroras signal more oxygen on Jupiter’s largest moon, Ganymede
in 2021, the Juno spacecraft passed within 1,053 kilometers of Jupiter’s moon Ganymede, getting a close look at the flow of plasma and charged particles between the massive magnetosphere of the planet and the moon. All of that electron inflow from Jupiter excites a UV aurora in the thin atmosphere of the moon, suggesting it holds 10 times more oxygen than previously calculated, and that a unique oxygen-generation process may be in effect on the solar system’s icy moons.

Meltwater from Everest’s East Rongbuk climbing route will peak by 2060
Climbers on Everest’s northeast ridge route from Tibet follow the East Rongbuk Glacier to Camp 1 at the North Col. Researchers picked the relatively well-measured East Rongbuk to improve modeling of ice dynamics and predictions of future change for glacier “water towers” that supply critical water needs for mountain communities. The glacier will continually lose mass this century, the study found, with annual meltwater volume peaking around 2060 if high greenhouse gas emissions continue.  [Earth’s Future research]

Can ice melt on the surface of present-day Mars?
Unlikely, according to new research that applies recent advances in modeling turbulent air flow on Earth to the Red Planet to estimate how fast ice sublimates to gas on the cold surface — and if any conditions would allow for liquid water.

Hot, dry conditions stymie forest recovery after wildfires
After a wildfire sweeps across a landscape, tree recovery is often critical for reestablishing ecosystems and stabilizing soils. But warmer, drier conditions in the U.S. are leading to lower tree regeneration rates after wildfires as compared to the 1980s and 1990s, a new study finds. Recovery may be depressed for five to seven years following a fire. [JGR Biogeoscience research]

Airline crew radiation exposure should be individually monitored
Commercial airlines typically fly at high altitudes, where there is more exposure to radiation, putting flight crews at higher risk. A new study measured radiation dose rates on 45 flights and found that while radiation levels did not exceed the international health standard, adding individual radiation dosimeters could improve monitoring. [Space Weather research]

Retreating glaciers cause catastrophic Himalayan hazard chain
Warming from climate change can make glaciers retreat more quickly and generate more meltwater. Such conditions can create a catastrophic chain of events: ice collapses and begins to flow downhill, accumulating water, ice and rocks. That debris flow can travel for kilometers, causing damage and instability. [Geophysical Research Letters research]

Climate change fueled eastern heatwaves and western flooding in Asia
Summer 2022 brought deadly floods to western Asia, while eastern Asia sweltered through the worst extended heatwave in 70 years.
