Climate Change Leads to Decline in Lichen Biocrusts

h ttps://eos.org/articles/climate-change-leads-to-decline-in-lichen-biocrusts By Derek Smith, Eos/AGU .  Excerpt: Biological soil crusts, or biocrusts, are communities of living organisms at the soil surface and are known as the “ living skin ” of dryland ecosystems. They cement soil grains together, thereby protecting dryland soils from erosion. Biocrusts also add critical nutrients to the soil by converting nitrogen in the atmosphere to ammonia, which serves as a kind of fertilizer for plants and microbes. Unfortunately, trampling by livestock and such human activity as driving vehicles off-road make biocrust survival difficult. New research published in the Proceedings of the National Academy of Sciences of the United States of America has suggested that there’s another phenomenon that biocrusts are sensitive to: climate change. ...The research was conducted on the Colorado Plateau within the Needles District of Canyonlands National Park in Utah. ...Increasing summertime temperat

Active Hurricane Season Expected in the Atlantic Ocean.

https://eos.org/articles/active-hurricane-season-expected-in-the-atlantic-ocean By V enessa Duncombe, Eos/AGU .  Excerpt: If forecasts are correct, this season will mark the seventh consecutive above-normal hurricane season for the Atlantic. NOAA forecasts out today predict a 65% chance of an above-average season, a 25% chance of a normal season, and a 10% chance of a below-normal season. The ranges account for uncertainty in the data and models of NOAA’s Climate Prediction Center ... . 

French dijon mustard supply hit by climate and rising costs, say producers

https://www.theguardian.com/business/2022/may/19/french-dijon-mustard-supply-hit-by-climate-and-rising-costs-say-producers By Robyn Wilson , The Guardian.  Excerpt: Climate change and rising costs are causing supermarkets in  France  to run out of dijon mustard, raising questions over whether the shortage could spread to other countries. French mustard producers said seed production in 2021 was down 50% after poor harvests, which they said had been brought on by the changing climate in France’s Burgundy region and  Canada , the second largest mustard seed producer in the world. It has caused French supermarket shelves to run empty of the condiment, including in several stores visited by the Guardian. One of France’s largest mustard producers, Reine de Dijon, said the shortages were being driven by climate breakdown. The group’s general manager, Luc Vandermaesen, said a “heat dome” in Canada at the beginning of July in 2021 had “really dried up the crops”.…

Europe Rethinks Its Reliance on Burning Wood for Electricity

https://www.nytimes.com/2022/05/17/climate/eu-burning-wood-electricity.html By  Lois Parshley , The New York Times.  Excerpt: In recent years, Europe’s power plants have slashed their use of coal by burning something else instead: Millions of tons of wood, much of it imported from the United States. A controversial European Union policy called the Renewable Energy Directive drove this transition by counting biomass — organic material like wood, burned as fuel — as renewable energy and subsidizing its use. A trans-Atlantic industry developed, logging American forests and processing the material into pellets, which are then shipped to Europe. But critics have long argued that the subsidies actually have few climate benefits and should be scrapped. Late Tuesday in Brussels, a committee of the European Parliament voted to make substantial changes to both how the union subsidizes biomass, and how it counts emissions from burning it — policies with major consequences if passed by the full Pa

Michael Bloomberg Plans a $242 Million Investment in Clean Energy

https://www.nytimes.com/2022/05/17/climate/michael-bloomberg-climate-coal.html By  Maggie Astor , The New York Times.  Excerpt: Michael R. Bloomberg, the former mayor of New York City, will announce a $242 million effort on Tuesday to promote clean energy in 10 developing countries. The investment is part of Mr. Bloomberg’s push,  announced last year , to shut down coal production in 25 countries and builds on his  $500 million campaign  to close every coal-fired power plant in the United States. The announcement is tied to a gathering this week in Rwanda hosted by Sustainable Energy for All, an international group working to increase access to electricity in the global south. The money will fund programs in Bangladesh, Brazil, Colombia, Kenya, Mozambique, Nigeria, Pakistan, South Africa, Turkey and Vietnam.…  

Here Are the Wildfire Risks to Homes Across the Lower 48 States

https://www.nytimes.com/interactive/2022/05/16/climate/wildfire-risk-map-properties.html By Christopher Flavelle  and  Nadja Popovich , The New York Times.  Excerpt: [county-by-county map of the U.S.] New data was used to calculate fire risk to residential and other properties. The threats are rising. ...The data,  released Monday by the First Street Foundation , a nonprofit research group in New York, comes as rising housing prices in cities and suburbs push Americans deeper into fire-prone areas, with little idea about the specific risk in their new locale.…

Cutting air pollution from fossil fuels would save 50,000 lives a year, study says.

https://www.washingtonpost.com/climate-solutions/2022/05/16/climate-change-air-pollution-saved-lives/ By  Steven Mufson , The Washington Post.  Excerpt: Eliminating air pollution caused by burning fossil fuels would prevent more than 50,000 premature deaths and provide more than $600 billion in health benefits in the United States every year, according to a  new study  by University of Wisconsin-Madison researchers. Published in the journal GeoHealth, the study reports the considerable health benefits of removing from the air harmful fine particulates, sulfur dioxide and nitrogen oxides produced by electricity generation, transportation, industrial activities, and building functions such as heating and cooking. Highway vehicles make up the largest single share.…  

Caesar’s favourite herb was the Viagra of ancient Rome. Until climate change killed it off

https://www.theguardian.com/world/2022/may/15/caesars-favourite-herb-was-the-viagra-of-ancient-rome-until-climate-change-killed-it-off By James Tapper , The Guardian.  Excerpt: Of all the mysteries of ancient Rome, silphium is among the most intriguing. Romans loved the herb as much as we love chocolate. They used silphium as perfume, as medicine, as an aphrodisiac and turned it into a condiment, called laser, that they poured on to almost every dish. ...Yet it became extinct less than a century later, by the time of Nero, and for nearly 2,000 years people have puzzled over the cause. Researchers now believe it was the first victim of man-made climate change – and warn that we should heed the lesson of silphium or risk losing plants that are the basis of many modern flavours. Paul Pollaro and Paul Robertson of the University of New Hampshire say their research, published in  Frontiers in  Conservation  Science , shows that urban growth and accompanying deforestation changed the local m

The Tesla Effect: Snowmobiles, Boats and Mowers Go Electric

https://www.nytimes.com/2022/05/15/business/electric-snowmobiles-boats-mowers.html By Jack Ewing , The New York Times.  Excerpt: STOWE, Vt. — Snowmobiles are part of the winter soundtrack in this part of Vermont, at their worst shattering the stillness of the forest like motorcycles on skis. But the motorized sleds bouncing along a wooded mountain trail in February were silent except for the whoosh of metal runners on snow. The machines, made by a start-up Canadian company,  Taiga , were battery-powered — the first electric snowmobiles to be sold widely — and symbols of how conveyances of all kinds are migrating to emission-free propulsion. Taiga is also offering battery-powered personal watercraft, another form of recreation where the gasoline version is regarded in some circles as a scourge. While electric cars get most of the attention, electric lawn mowers, boats, bicycles, scooters and all-terrain vehicles are proliferating. In some categories, battery-powered machines are gaining

The Colorado River Is In Crisis, and It's Getting Worse Everyday

https://www.washingtonpost.com/business/interactive/2022/colorado-river-crisis/ By Karin Brulliard , The Washington Post.  Excerpt: ...the Colorado’s water was overpromised when it was first allocated a century ago. Demand in the fast-growing Southwest exceeds supply, and it is growing even as supply drops amid a climate change-driven megadrought and rising temperatures. ...As temperatures rise, the mountain snowpack that feeds the Colorado river is diminishing over time and melting earlier. That decreasing runoff is more quickly soaking into Western Colorado’s parched terrain and evaporating into its hotter air. Less water is flowing downriver, depriving the ranchers, rafters, anglers and animals who depend on it.…

Poisoned legacy: why the future of power can’t be nuclear

https://www.theguardian.com/books/2022/may/14/poisoned-legacy-why-the-future-of-power-cant-be-nuclear By  Serhii Plokhy , The Guardian.  Excerpt: ...On the surface, the switch to nuclear makes sense. It would not only enable European countries to meet their ambitious net zero targets, since it produces no CO 2 . It would also make them less vulnerable to Russian threats, and allow them to stop financing the Russian war machine. But the invasion also provided a chilling reminder of just why so many governments have treated nuclear power with great caution over the years. On the first day, Russian troops in unmarked uniforms took control of the  Chernobyl nuclear  power plant, the site of the worst ever nuclear disaster. On the following day, electronic monitors in the Chernobyl exclusion zone indicated sharp spikes in radiation levels as heavy equipment and trench-digging by Russian soldiers threw up contaminated dust. The world woke up to an even more nightmarish reality a week later,

In London, a Long-Awaited High-Tech Train Is Ready to Roll

https://www.nytimes.com/2022/05/14/world/europe/london-train-crossrail.html By Mark Landle r, Photographs by Andrew Testa, The New York Times.  Excerpt: LONDON — When Andy Byford ran New York City’s dilapidated subway system, fed-up New Yorkers hailed his crusade to make the trains run with fewer delays and lamented his premature exit after clashes with the governor at the time, Andrew M. Cuomo. ...Straphangers even took to  calling him “Train Daddy.” Nobody calls Mr. Byford Train Daddy in London, where  he resurfaced in May 2020  as the commissioner of the city’s transit authority, Transport for London. But on May 24, when he opens the Elizabeth line — the long-delayed, $22 billion-plus high-capacity railway that uncoils from west and east underneath central London — he might find himself again worthy of a cheeky nickname. ...Heathrow Airport has had a subway link for decades. When the Elizabeth line’s next phase is opened in the fall, passengers will be able to travel from Heathrow

Did Warming Play a Role in Deadly South African Floods? Yes, a Study Says

https://www.nytimes.com/2022/05/13/climate/south-africa-floods-climate-change.html By Henry Fountain , The New York Times.  Excerpt: The heavy rains that caused  catastrophic flooding in South Africa  in mid-April were made twice as likely to occur by climate change, scientists said Friday. An analysis of the flooding, which killed more than 400 people in Durban and surrounding areas in the eastern part of the country, found that the intense two-day storm that caused it had a 1-in-20 chance of occurring in any given year. If the world had not warmed as a result of human-caused emissions of greenhouse gases, the study found, the chances would have been half that, 1 in 40. The study, by a loose-knit group of climate scientists, meteorologists and disaster experts called  World Weather Attribution , is the latest in a string of analyses showing that the damaging effects of global warming, once considered a future problem, have already arrived. And extreme events like this one are expecte

Lithium Valley: Imperial County big winner in California budget revision

https://www.desertsun.com/story/news/environment/2022/05/13/lithium-valley-imperial-county-big-winner-california-budget-revision/9752840002/ By  Janet Wilson , Palm Springs Desert Sun.  Excerpt: California Gov. Gavin Newsom wants to add up to $400 million to the 2022-23 budget to accelerate development of a potential huge global supply of lithium and clean energy at the south end of the Salton Sea, .... “Lithium Valley represents an extraordinary economic opportunity for the Imperial Valley and all of California, with the potential to power the transition to clean energy and zero-emission vehicles nationwide — and beyond,” Newsom said. “We’re doubling down on our progress with new investments to develop Lithium Valley while keeping our values of inclusive, green growth and sustainability front and center to ensure communities in the region share in the benefits.” ...President Joe Biden and U.S. Energy Secretary Jennifer Granholm, along with Newsom, have in recent months promoted the li

The swift march of climate change in North Carolina’s ‘ghost forests’

https://www.washingtonpost.com/climate-environment/2022/05/12/ghost-forests-carolina-climate-change/ By Brady Dennis , The Washington Post.  Excerpt: ...Few examples of climate change are as unmistakable and arresting as the “ghost forests” proliferating along parts of the East Coast — and particularly throughout the Albemarle-Pamlico Peninsula of North Carolina. Places where Lanier once stood on dry ground are now in waist-deep water. Forests populated by towering pines, red maple, sweet gum and bald cypress have transitioned to shrub land. Stretches of shrub habitat have given way to marsh. And what once was marsh has succumbed to the encroaching sea. ... As sea levels rise, droughts deepen and storms become more intense, saltier water makes its way into these woodlands more readily from surrounding water bodies, as well as deeper into the sprawling network of drainage ditches and irrigation canals created long ago to support the expansion of agriculture. Persistently wet conditions

Madison, Wis., Chicago, Des Moines, St. Louis, Kansas, Little Rock and New Orleans could all set record highs above 90 degrees Thursday.…

Violent storms blast Upper Midwest with hurricane-force winds, dust

https://www.washingtonpost.com/weather/2022/05/12/derecho-dust-storm-southdakota-minnesota/ By Matthew Cappucci  and  Jason Samenow , The Washington Post.  Excerpt: WATERTOWN, S.D. — A violent complex of storms roared through the Upper Midwest on Thursday evening, unleashing destructive wind gusts over 100 mph while stirring up a towering wall of dust. ...The dust cloud swept up by the storm produced scenes reminiscent of the Dust Bowl of the 1930s. Technically called a “haboob,” it swallowed entire communities as the storm complex, racing northeast at breakneck speeds of 65 to 85 mph, turned day into night. ...Producing widespread damage along an extensive path, the storm complex met some criteria of a  derecho  — the meteorological term for an arcing, fast-moving line of violent storms whose damage can be comparable to a hurricane. ...As of 11 a.m. Eastern time Friday, the Weather Service’s Storm Prediction Center had received 59 reports of winds gusting over 74 mph.  second most on

Wildfire, Drought, and Insects Threaten Forests in the United States

https://eos.org/articles/wildfire-drought-and-insects-threaten-forests-in-the-united-states By Rishika Pardikar , Eos/AGU.  Excerpt: Western forest managers face a catch-22: They can keep carbon sequestered in trees by reducing controlled burns, but that creates denser forests at greater risk of going up in uncontrolled flames. Wildfire risk to forests across the United States is set to increase by a factor of 4, and tree mortality caused by other climate-induced factors like drought, heat, disease, and insects is set to at least double, new research shows. “Forests in the western half of the U.S. have the highest vulnerability to each of these risks,” said  William Anderegg , an associate professor at the University of Utah and lead author of the paper, which was  published   in  Ecology Letters . But risks are not confined to the West. There are wildfire risks in Florida and Georgia, as well as parts of Oklahoma and Texas, and insect and drought risks in the northern Great Lakes sta

Revealed: the ‘carbon bombs’ set to trigger catastrophic climate breakdown

https://www.theguardian.com/environment/ng-interactive/2022/may/11/fossil-fuel-carbon-bombs-climate-breakdown-oil-gas By  Damian Carrington  and  Matthew Taylor , The Guardian.  Excerpt: The world’s biggest fossil fuel firms are quietly planning scores of “carbon bomb” oil and gas projects that would drive the climate past internationally agreed temperature limits with catastrophic global impacts, a Guardian investigation shows. The exclusive data shows these firms are in effect placing multibillion-dollar bets against humanity halting global heating. Their huge investments in new fossil fuel production could pay off only if countries fail to rapidly slash carbon emissions, which scientists say is vital.  The oil and gas industry is extremely volatile but extraordinarily profitable, particularly when prices are high, as they are at present. ExxonMobil, Shell, BP and Chevron have made almost  $2tn in profits  in the past three decades, while recent price rises led BP’s boss to describe

Just one of 50 aviation industry climate targets met, study finds

https://www.theguardian.com/environment/2022/may/10/just-one-of-50-aviation-industry-climate-targets-met-study-finds By Damien Gayle , The Guardian.  Excerpt: The international aviation industry has failed to meet all but one of 50 of its own climate targets in the past two decades, environment campaigners say. A report commissioned by the climate charity Possible assessed every target set by the industry since 2000 and found that nearly all had been missed, revised or quietly ignored. The charity says the findings undermine a UK government plan to leave airlines to reduce their emissions through self-regulation.…

Lowly mushrooms may be key to ecosystem survival in a warming world

https://www.science.org/content/article/lowly-mushrooms-may-be-key-ecosystem-survival-warming-world By Elizabeth Pennisi, Science Magazine.  Excerpt: Fungi that decompose plant matter may keep ecosystems healthy, especially after drought. ...Across a wide variety of ecosystems, from grasslands to forests to deserts, the more species of decomposers, the  more plant productivity stayed the same over time , Delgado-Baquerizo and colleagues report today in Nature Ecology & Evolution. Having a wide variety of decomposers and to a lesser extent, root fungi, also helped keep the vegetation growing even in dry spells, the authors found. This diversity might ensure that no matter how conditions change, some fungi will still be able to supply the plants above them with nutrients.…

As record-setting heat blasts Pakistan, a glacial lake floods village

https://www.washingtonpost.com/weather/2022/05/09/pakistan-heat-flood-glacier/ By Kasha Patel , The Washington Post.  Excerpt: Record-high April temperatures over Pakistan melted glaciers faster than normal, triggering a flash flood Saturday in a village in the northern region of the country that wiped out part of a key bridge and damaged homes and buildings. The event, known as a glacial lake outburst flood, occurs when water is suddenly released from a glacial lake because of a dam failure or breach. Warmtemperatures over the past month accelerated snow and ice melt near an ice-dammed lake by Shishpar glacier, near Mount Shishpar, increasing the lake’s volume and likely causing the breachand water to overflow across the top.…

India tries to adapt to extreme heat but is paying a heavy price

https://www.washingtonpost.com/world/2022/05/09/india-heat-wave-climate-change/ By Gerry Shih  and  Kasha Patel , The Washington Post.  Excerpt: ...Typically, heat waves in India affect only part of the country, occur in the summer and only last for a week or so. But a string of early heat waves this spring has been longer and more widespread than any observed before. India experienced its hottest March on record. Northwest and central India followed with their hottest April. “This probably would be the most severe heat wave in March and April in the entire [recorded] history” of India, said Vimal Mishra, a climate scientist at Indian Institute of Technology   Gandhinagar. ...India loses more than 100 billion hours of labor per year because of extreme heat, the most of any country in the world, according to  research  published in Nature Communications. ...The extreme heat is straining not only farmers but also their crops, as high temperatures coincided with the final weeks of the pla

Climate limit of 1.5C close to being broken, scientists warn

https://www.theguardian.com/environment/2022/may/09/climate-limit-of-1-5-c-close-to-being-broken-scientists-warn By Damian Carrington , The Guardian.  Excerpt: The year the world breaches for the first time the 1.5C global heating limit set by international governments is fast approaching, a new forecast shows. The probability of one of the next five years surpassing the limit is now 50%, scientists led by the UK Met Office found. As recently as 2015, there was zero chance of this happening in the following five years. But this surged to  20% in 2020  and  40% in 2021 . The global average temperature was 1.1C above pre-industrial levels in 2021.…

Climate Action Plans Tailored to Indian Cities

https://eos.org/articles/climate-action-plans-tailored-to-indian-cities By Deepa Padmanaban , Eos/AGU.  Excerpt: Many Indian cities are developing climate action plans to adapt to increasing risks they face because of climate change (such as flooding and heat waves) and to mitigate greenhouse emissions associated with extensive  urbanization . Abinash Mohanty , program lead for the Council on Energy, Environment and Water, New Delhi, said, “The discourse of city climate action plans started because the hierarchy of decisionmaking, operation, preparedness, prevention, and mitigation is different at city and national levels. We need to understand where the hyperlocal action happens—that can only happen at a city level.” Mumbai  is the latest Indian city to release a climate action plan (CAP).…

Hawaii Legislature Calls For Fossil Fuel Non-Proliferation Treaty

https://www.commondreams.org/news/2022/05/06/hawaii-legislature-calls-fossil-fuel-non-proliferation-treaty By Andrea Germanos, Common Dreams.  Excerpt: Hawaii lawmakers put the  state on the path to making history after the Legislature passed a resolution Thursday endorsing a document called the " Fossil Fuel Non-Proliferation Treaty ." "Hawaii has reminded the world of the climate leadership and spirit communities throughout the Pacific have embodied for decades by calling for the immediate phaseout fossil fuels and... a just transition to ensure the survival and continued flourishing of our peoples and our planet for generations to come," said Auimatagi Joe Moeono-Kolio, a campaigner with the Fossil Fuel Non-Proliferation Treaty Initiative. ...Senate Concurrent Resolution 108, introduced by state Sen. Karl Rhoads (D-13),  passed  the upper chamber Thursday after clearing the House last month. The measure affirms Hawaii's commitment to the Paris Climate Agreem

Bogs, lakebeds, and sea floors compete to become Anthropocene’s ‘golden spike’

https://www.science.org/content/article/bogs-lakebeds-and-sea-floors-compete-become-anthropocene-s-golden-spike By Paul Voosen, Science Magazine.  Excerpt: If you had to pick one spot that best reflects when human activity became an Earth-shaping force, where would it be? Geoscientists will consider the question this month when they meet to evaluate 12 sites, only one of which can serve as the “golden spike” for the Anthropocene, a proposed geological age beginning in the 1950s amid the fire of nuclear bomb tests and the fumes of  surging fossil fuel use . Although the idea of the Anthropocene  has gained wide traction , it still lacks a formal geological definition. In 2016, the Anthropocene Working Group (AWG), a group of several dozen geoscientists convened by the International Commission on Stratigraphy (ICS),  settled on the early 1950s as its starting point . But the ICS still needs a formal proposal with an ideal geologic sample recording these global changes—a golden spike—to m
