Maui Endures More Drought and Drier Streams

https://eos.org/articles/maui-endures-more-drought-and-drier-streams By Kimberly M. S. Cartier , Eos/AGU.  Excerpt: Drought continues to threaten Maui’s native land-based and marine ecosystems, water resources, and traditional ways of life. But conservationists have hope—and ways to fight back. ...Ultimately,  swift and robust climate action  will reduce the frequency and severity of drought on Maui and other Pacific islands. But much can be done in the meantime to mitigate the impacts of drought on island ecosystems. For example, building and maintaining fences can keep invasive ungulates from damaging vulnerable ground and spreading non-native plant seeds and pathogens.…

Climate Change Worsened Britain’s Heat Wave, Scientists Find

https://www.nytimes.com/2022/07/28/climate/britain-heat-wave-climate-change.html By Raymond Zhong , The New York Times.  Excerpt: The heat that  demolished records in Britain  last week, bringing temperatures as high as 104.5 degrees Fahrenheit to a country unaccustomed to scorching summers, would have been “extremely unlikely” without the influence of human-caused climate change, a new scientific report issued Thursday has found. ... those temperatures were at least 10 times as likely as they would have been in a world without greenhouse-gas emissions, and at least 3.6 degrees Fahrenheit hotter. ...As the burning of fossil fuels causes average global temperatures to rise, the range of possible temperatures shifts upward, too, making blistering highs more likely. ...trains were slowed out of fear that the steel rails could buckle in the heat. Grass fires spread to London homes, shops and vehicles in what the city described as the Fire Brigade’s busiest day since World War II. More than

How the boom in air conditioning is fuelling global heating

https://www.theguardian.com/news/2022/jul/28/how-the-boom-in-air-conditioning-is-fuelling-global-heating By Jeremy Plester , The Guardian.  Excerpt: It is a vicious cycle – as the climate grows hotter,  demand for air conditioning is booming  and that is helping make the climate even hotter. Air conditioning accounts for about a fifth of the total electricity used in buildings around the world. Much of that electricity comes from power stations giving off greenhouse gases, and to make matters worse, air conditioners can also leak  hydrofluorocarbon refrigerants , greenhouse gases thousands of times more powerful than carbon dioxide over a 20-year period.…

Massive undersea eruption filled atmosphere with water

https://www.science.org/content/article/massive-undersea-eruption-filled-atmosphere-water By Nathaniel Scharping, Science Magazine.  Excerpt: On 15 January, Tonga’s Hunga Tonga-Hunga Ha'apai volcano erupted under the sea, rocking the South Pacific nation and sending tsunamis racing around the world. The eruption was the  most powerful ever recorded , causing an atmospheric shock wave that circled the globe four times, and sending a plume of debris more than 50 kilometers into the atmosphere. ...The ash and gasses punching into the sky also shot billions of kilograms of water into the atmosphere, a new study concludes. That water will likely remain there for years, where it could eat away at the ozone layer and perhaps even warm Earth. ...In all,  the plume shot approximately 146 billion kilograms of water into Earth’s stratosphere , an arid layer of the atmosphere that begins several miles above sea level, the authors report this month in Geophysical Research Letters. ...Other volc

Unearthing the Secret Superpowers of Fungus

https://www.nytimes.com/interactive/2022/07/27/climate/climate-change-fungi.html By Somini Sengupta, The New York Times.  Excerpt: Some species of fungi can store exceptional levels of carbon underground, keeping it out of the air and preventing it from heating up the Earth’s atmosphere. Others help plants survive brutal droughts or fight off pests. There are those especially good at feeding nutrients to crops, reducing the need for chemical fertilizers. ...By  one estimate , 5 billion tons of carbon flow from plants to mycorrhizal fungi annually. Without help from the fungi, that carbon would likely stay in the atmosphere as carbon dioxide, the powerful greenhouse gas that is heating the planet and fueling dangerous weather. “Keeping this fungal network protected is paramount as we face climate change,” Dr. Kiers said. In addition, the biodiversity of underground fungi is a huge factor in soil health, which is crucial to the world’s ability to feed itself as the planet warms.…

Flash Floods Swamp St. Louis Area, Breaking a Century-Old Rain Record

https://www.nytimes.com/2022/07/26/us/flash-flooding-st-louis-missouri.html By  Michael Levenson ,  Christine Hauser  and Eric Berger, The New York Times.  Excerpt: ...More than nine inches of rain fell in the St. Louis area overnight, the highest 24-hour rainfall total on record there,  the National Weather Service said . It surpassed the 7.02 inches that fell in 1915 from the remnants of the Galveston hurricane. The normal amount of rain in St. Louis for July and August combined is 7.31 inches. By Tuesday morning, 10 to 12 inches of rain had fallen in parts of eastern Missouri,  the National Weather Service said . The largest total was 12.34 inches in St. Peters, northwest of St. Louis, the agency said, noting that rain continued to fall.… 

In San Antonio, the Poor Live on Their Own Islands of Heat

https://www.nytimes.com/2022/07/26/us/texas-heat-poverty-islands-san-antonio.html By  Edgar Sandoval , The New York Times.  Excerpt: In San Antonio, weathering the second week of a heat wave that has been ferocious even by Texas standards, lower-income residents like Ms. Cruz-Perez are sometimes left with few options to relieve the misery. Not only can she not afford air-conditioning during the hottest part of the day, she lives in the Westside, one of several parts of San Antonio — nearly all of them working-class or poor neighborhoods — where there are few trees to provide shade. ...San Antonio has seen at least 46 days of 100-plus-degree weather so far this year, according to the National Weather Service. Through July 25, measurements taken at the city’s airport have detected that all but one day in July has surpassed the 100-degree mark.The heat wave has been blamed for a series of wildfires, including a blaze that damaged more than 20 homes  on Monday evening in Balch Springs , a

Congo to Auction Land to Oil Companies: ‘Our Priority Is Not to Save the Planet’

https://www.nytimes.com/2022/07/24/world/africa/congo-oil-gas-auction.html By Ruth Maclean  and  Dionne Searcey , The New York Times.  Excerpt: DAKAR, Senegal — The Democratic Republic of Congo, home to one of the largest old-growth rainforests on earth, is auctioning off vast amounts of land in a push to become “the new destination for oil investments,” part of a global shift as the world retreats on fighting climate change in a scramble for fossil fuels. The oil and gas blocks, which will be auctioned in late July, extend into Virunga National Park, the world’s most important gorilla sanctuary, as well as  tropical peatlands  that  store vast amounts of carbon , keeping it out of the atmosphere and from contributing to global warming. “If oil exploitation takes place in these areas, we must expect a global climate catastrophe, and we will all just have to watch helplessly,” said Irene Wabiwa, who oversees the Congo Basin forest campaign for Greenpeace in Kinshasa. ...said Tosi Mpanu

Heat Waves Sweep the Northeast Over Sweltering Weekend

https://www.nytimes.com/2022/07/24/nyregion/heat-wave-us.html ]  By Ali Watkins , The New York Times.  Excerpt: Scorching temperatures swept the Northeast on Sunday in the region’s first prolonged heat wave of the summer, with a record-breaking five straight days of triple-digit temperatures in Newark and blistering heat in Boston; Providence, R.I.; and Manchester, N.H. Other parts of the country also sweltered, with Oklahoma enduring temperatures that have topped 100 degrees in nine of the past 11 days. The baking heat underscored the sobering reality that such dangerous temperatures are becoming a summertime norm for the United States and elsewhere, with  heat waves ,  wildfires  and  droughts   disrupting day-to-day life  across the globe .…

Nobel Recognition for the Roles of Complexity and Intermittency

https://eos.org/opinions/nobel-recognition-for-the-roles-of-complexity-and-intermittency By  Daniel Schertzer  and   Catherine Nicolis , Eos/AGU.  Excerpt:  The 2021 Nobel Prize in Physics was awarded to three scientists “for groundbreaking contributions to our understanding of complex physical systems.”  ...Until recently, the Nobel Committee for Physics has been more used to awarding scientists for tracking down the elementary building blocks of the universe. Yet in October 2021, the committee  awarded the prize  jointly to three scientists who revolutionized nonlinear physics with insights into complex systems. Specifically, Syukuro Manabe and Klaus Hasselmann were awarded “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming,” and Giorgio Parisi was awarded “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.” ...According to the  French Roadmap for Complex Syst

A Painful Deadline Nears as Colorado River Reservoirs Run Critically Low

https://www.nytimes.com/2022/07/21/climate/colorado-river-water-cuts.html By  Henry Fountain s, The New York Times.  Excerpt: States in the Colorado River basin are scrambling to propose steep cuts in the water they’ll use from the river next year, in response to a call by the federal government for immediate, drastic efforts to keep the river’s main storage reservoirs from reaching critically low levels. The request comes with the Southwest still in the grip of a severe two-decade drought that shows no signs of letting up. And it comes on top of earlier, less desperate, efforts to keep more water in the two reservoirs, Lake Mead and Lake Powell, including  a first-ever shortage declaration  last year that cut water to farmers in Arizona. ...the long-term outlook for the Colorado is bleak, as climate change continues to affect runoff into the river and reduces the likelihood of a series of wet years that could end the drought. The request for cuts has further exposed the fault lines be

‘In 10 years, we might not have forests’: DRC struggles to halt charcoal trade – a photo essay

https://www.theguardian.com/global-development/2022/jul/20/in-10-years-we-might-not-have-forests-drc-struggles-to-halt-charcoal-trade-a-photo-essay By Ed Ram , The Guardian.  Excerpt: ...The rainforest of the Congo River basin covers 178m hectares (440m acres) across  six countries . It absorbs about 4% of global annual carbon emissions, sustains rainfall as far away as Egypt, and is home to 80 million people – and a vast spectrum of rare animals, insects and flora. Its preservation is deemed  key in the fight against global heating . But DRC has one of the world’s highest rates of deforestation,   losing 490,000 hectares (1.2m acres) of primary rainforest in 2020 , according to Global Forest Watch. Unlike in the Amazon, where industrial-scale logging is mostly responsible, in DRC [ Democratic Republic of the Congo ] small-scale charcoal production and slash and burn agriculture drive deforestation; about 90% of forest loss between 2000 and 2014 was due to smallholder agriculture, acco

In a paradox, cleaner air is now adding to global warming

https://www.science.org/content/article/paradox-cleaner-air-now-adding-global-warming By Paul Voosen, Science Magazine.  Excerpt: It’s one of the paradoxes of global warming. Burning coal or gasoline releases the greenhouse gases that drive climate change. But it also lofts pollution particles that reflect sunlight and cool the planet, offsetting a fraction of the warming. Now, however, as pollution-control technologies spread, both the noxious clouds and their silver lining are starting to dissipate. Using an array of satellite observations, researchers have found that  the climatic influence of global air pollution has dropped by up to 30% from 2000 levels . Although this is welcome news for public health—airborne fine particles, or aerosols, are believed to kill several million people per year—it is bad news for global warming. The cleaner air has effectively boosted the total warming from carbon dioxide emitted over the same time by anywhere from 15% to 50%, estimates Johannes Quaa

‘It goes up like tinder’: unprecedented blazes envelop Alaska

https://www.theguardian.com/us-news/2022/jul/18/alaska-wildfires-east-fork-lime-complex By  Brendan Jones , The Guardian.  Excerpt: Across the state, 264 individual fires are burning and it is on track to break its 2004 record of 6.5m acres destroyed. Alaska has seen more than 500 forest fires since the beginning of April, which have forced the evacuation of mining camps, villages and remote cabins. By 15 June,  more than 1m acres  (405,000 hectares) in the state had already gone up in flames, about the amount of acres that would normally burn in an entire fire season. By mid-July, more than 3m acres of land had been torched, putting the state at risk of breaking its  2004 record  of 6.5m acres (2.6m hectares) burned.…

‘Heat apocalypse’ warning in western France as thousands flee wildfire

https://www.theguardian.com/world/2022/jul/18/heat-apocalypse-warning-western-france-thousands-flee-wildfire By  Jon Henley   and   Sam Jones , The Guardian.  Excerpt: Meteorologists have warned of a “heat apocalypse” in western France as more than 8,500 further people fled their homes to escape a large wildfire sparked by a searing southern European heatwave that has already caused hundreds of deaths. Nearly 25,000 people have been forced to abandon homes, holiday rentals and campsites for emergency shelters in the Gironde département west of Bordeaux, while blazes in Spain,  Portugal  and Greece have forced thousands more to flee. Temperatures across southern Europe showed some sign of abating on Monday as the heatwave, during which temperatures have surpassed 40C (104F) across much of the region, moved north, including towards Britain, which was set for its hottest day on record.… See also:  Europe’s heatwave moves north as UK braces for hottest day on record ; and  UK has hottest n

This Pioneering Economist Says Our Obsession With Growth Must End

https://www.nytimes.com/interactive/2022/07/18/magazine/herman-daly-interview.html By David Marchese, The New York Times.  Excerpt: Growth is the be-all and end-all of mainstream economic and political thinking. Without a continually rising G.D.P., we’re told, we risk social instability, declining standards of living and pretty much any hope of progress. But what about the counterintuitive possibility that our current pursuit of growth, rabid as it is and causing such great ecological harm, might be incurring more costs than gains? That possibility — that prioritizing growth is ultimately a losing game — is one that the lauded economist Herman Daly has been exploring for more than 50 years. In so doing, he has developed arguments in favor of a steady-state economy, one that forgoes the insatiable and environmentally destructive hunger for growth, recognizes the physical limitations of our planet and instead seeks a sustainable economic and ecological equilibrium. ...I’m not against gro

Catching fire

https://www.sciencemagazinedigital.org/sciencemagazine/library/item/15_july_2022/4027473/ By Warren Cornwall, Science Magazine.  Excerpt: The concept of using Earth’s internal heat to generate electricity is attractively simple. ...By one recent estimate, more than 5000 gigawatts of electricity could be extracted from heat in rock beneath the United States alone. That’s nearly five times the total currently generated by all U.S. power plants. Geothermal energy is also attractive because it doesn’t burn fossil fuels, isn’t imported, and can run around the clock, unlike solar panels and wind turbines. Tapping that heat, however, has proved difficult. Some nations—notably volcanically active Iceland—siphon hot groundwater to heat buildings and generate electricity In most places, however, the rock lacks the water or the cracks needed to easily move heat to the surface. ...geothermal energy provides just 0.33% of the world’s electricity, little changed from 1990, according to the Internati

In a Twist, Old Coal Plants Help Deliver Renewable Power. Here’s How

https://www.nytimes.com/2022/07/15/climate/coal-plants-renewable-energy.html By  Elena Shao , The New York Times.  Excerpt: ...Across the country, aging and defunct coal-burning power plants are getting new lives as solar, battery and other renewable energy projects, partly because they have a decades-old feature that has become increasingly valuable: They are already wired into the power grid. The miles of high-tension wires and towers often needed to connect power plants to customers far and wide can be costly, time consuming and controversial to build from scratch. So solar and other projects are avoiding regulatory hassles, and potentially speeding up the transition to renewable energy, by plugging into the unused connections left behind as coal becomes uneconomical to keep burning. In Illinois alone, at least nine coal-burning plants are on track to become solar farms and battery storage facilities in the next three years. Similar projects are taking shape in Nevada, New Mexico, C

How One Senator Doomed the Democrats’ Climate Plan

https://www.nytimes.com/2022/07/15/climate/manchin-climate-change-democrats.html By Coral Davenport  and  Lisa Friedman , The New York Times.  Excerpt: ...First, he killed a plan that would have forced power plants to clean up their climate-warming pollution. Then, he shattered an effort to help consumers pay for electric vehicles. And, finally, he said he could not support government incentives for solar and wind companies or any of the other provisions that the rest of his party and his president say are vital to ensure a livable planet. Senator Joe Manchin III of West Virginia, who  took more campaign cash  from the oil and gas industry than any other senator, and  who became a millionaire  from his family coal business,  independently blew up  the Democratic Party’s legislative plans to fight climate change. The swing Democratic vote in an evenly divided Senate, Mr. Manchin led his party through months of tortured negotiations that collapsed on Thursday night, a yearlong wild goose

Metropolis meltdown: the urgent steps we need to take to cool our sweltering cities

https://www.theguardian.com/artanddesign/2022/jul/14/climate-crisis-metropolis-meltdown-urgent-steps-cool-sweltering-cities By Oliver Wainwright , The Guardian.  Excerpt: ...As hot, developing nations become more prosperous, and prosperous nations become hotter, the International Energy Agency estimates that the energy spent on air conditioning will triple by 2050 – a growth equivalent to the current electricity demand in the US and Germany combined. ...The biggest cause of the  urban heat island effect  – which can make cities up to 10C warmer than neighbouring rural areas – is the stuff they are made of: hard, dark, dense materials like concrete, brick, tarmac and asphalt, which absorb the sun’s heat during the day, and re-radiate it at night. It sounds too simple a solution, but some argue that one of the most effective measures to cool cities down is to make their surfaces reflect light, rather than absorb it – particularly where you might not think to look: up on the roof.

In ominous sign for global warming, feedback loop may be accelerating methane emissions

https://www.science.org/content/article/ominous-sign-global-warming-feedback-loop-may-be-accelerating-methane-emissions By Paul Voosen, Science Magazine.  Excerpt: If carbon dioxide is an oven steadily roasting our planet, methane is a blast from the broiler: a more potent but shorter lived greenhouse gas that’s responsible for  roughly one-third  of the 1.2°C of warming since preindustrial times. Atmospheric methane levels have risen nearly 7% since 2006, and the past 2 years saw the  biggest jumps yet , even though the pandemic slowed oil and gas production, presumably reducing methane leaks. Now, researchers are homing in on the source of the mysterious surge. Two new preprints trace it to microbes in tropical wetlands. Ominously, climate change itself might be fueling the trend by driving increased rain over the regions. If so, the wetlands emissions could end up being a runaway process beyond human control, although the magnitude of the feedback loop is uncertain. “We will have ha

How does Caribbean fire coral thrive as others vanish?

https://www.science.org/content/article/how-does-caribbean-fire-coral-thrive-others-vanish By Elizabeth Pennisi, Science Magazine.  Excerpt: Fire corals can be the bane of a scuba diver’s existence. An accidental brush against one can cause agonizing pain. But they also may help save Caribbean reefs, which have been plagued by hurricanes, global warming, disease, and an overabundance of algae. A long-term study has revealed that fire corals ( Millepora ) are thriving there even as other corals disappear and could help preserve some of the 3D environment that helps make reefs such great homes to fish and other organisms.… 

Nearly $2trillion of damage inflicted on other countries by US emissions

https://www.theguardian.com/environment/2022/jul/12/us-carbon-emissions-greenhouse-gases-climate-crisis By  Oliver Milman , The Guardian.  Excerpt: The US has inflicted more than $1.9trillion in damage to other countries from the effects of its greenhouse gas emissions, according to a new analysis that has provided the first measurement of nations’ liability in stoking the climate crisis. The huge volume of planet-heating gases pumped out by the US, the largest historical emitter, has caused such harm to other, mostly poor, countries through heatwaves, crop failures and other consequences that the US is responsible for $1.91tn in lost global income since 1990, the study found. This puts the US ahead of China, currently the world’s leading emitter, Russian, India and Brazil as the next largest contributors to global economic damage through their emissions. Combined, these five leading culprits have caused a total of $6tn in losses worldwide, or about 11% of annual global GDP, since 1990

Dangerous heatwaves engulf parts of China, US and Europe

https://www.theguardian.com/world/2022/jul/12/dangerous-heatwaves-engulf-parts-china-us-europe By   Vincent Ni ,  Sam Jones , and  Nina Lakhani , The Guardian.  Excerpt: Dangerous heatwaves are engulfing parts of China,  Europe , south-west and central US this week, as dozens of cities have found themselves dealing with soaring summer temperatures. By Tuesday afternoon, at least 86 Chinese cities in eastern and southern parts of the country had issued heat alerts. Chinese meteorologists forecast temperatures in some cities would top 40C (104F) in the next 24 hours. In Shanghai, China’s most populous city, the authorities have told its 25 million people to prepare for unusually hot weather. Since record-keeping began in 1873, Shanghai has had only 15 days with temperatures above 40C. ...Heatwave-related mortality has risen by a factor of four from 1990 to 2019, reaching 26,800 deaths in 2019, according to  a Lancet study  published in 2020.… 

Companies’ Climate Promises Face a Wild Card: Farmers

https://www.nytimes.com/2022/07/09/business/farmers-climate-change.html By  Julie Creswell , The New York Times.  Excerpt: ...Companies like PepsiCo, Cargill, Walmart, and General Mills are trying to convince farmers like Mr. Gaesser to adopt new climate-friendly agricultural techniques through a variety of financial incentives and programs. They have good reason. Together, these companies have pledged that at least 70 million acres, or roughly 18 percent of the nation’s total cropland, an area about the size of Nevada, will be operated using regenerative agriculture techniques by 2030. ...Through photosynthesis, plants — whether corn or trees — convert carbon dioxide from the air into energy that is stored in the soil. Regenerative farming techniques, such as planting a cover crop during the fall, allows that process to continue throughout the winter months when the soil would normally be bare. But there are several complicating factors. The programs sponsored by the companies, which

Global atmospheric CO2 concentration is still rising

https://gml.noaa.gov/ccgg/trends/index.html ]  By NOAA Global Monitoring Laboratory.  For the most current atmospheric carbon dioxide data in graphical form, see https://gml.noaa.gov/ccgg/trends/index.html where graphs show monthly mean carbon dioxide measured at Mauna Loa Observatory, Hawaii. But CAUTION, prepare to be depressed: the concentration of CO 2 in the Earth's atmosphere is still rising, owing largely to human combustion of fossil fuels. As you should know by now, the greenhouse effect coupled with rising CO 2 atmospheric concentrations means that we expect global average temperatures to rise accordingly along with all the unpleasant consequences associated with global warming.

Glacier Tragedy Shows Reach of Europe’s New Heat

https://www.nytimes.com/2022/07/07/world/europe/italy-glacier-collapse.html By  Jason Horowitz , The New York Times.  Excerpt: CANAZEI, Italy — Days before a glacier in the Italian Dolomites broke off with the force of a collapsing skyscraper, crushing at least nine hikers under an avalanche of ice, snow and rock, Carlo Budel heard water running under the ice. ...A year after  Greece lost lives, livestock and entire swaths of forest  to wildfires, and  deadly floods swept through Germany , the calamity in these mountains this week provided the latest evidence that almost no part of the continent can escape the effects of Europe’s new, intense and often unlivable  summer heat . That includes the highest peak of the Dolomites. Italy is suffering through another prolonged and scorching heat wave, which contributed to the disaster and has brought the worst drought in 70 years along the Po River, its longest waterway, cutting off fountains and parching parts of the country. ...In the last 2

E.P.A. Describes How It Will Regulate Power Plants After Supreme Court Setback

https://www.nytimes.com/2022/07/07/climate/epa-greenhouse-gas-power-plant-regulations.html By  Lisa Friedman , The New York Times.  Excerpt: Following the Supreme Court’s  landmark ruling last week limiting the government’s ability to restrict the pollution that is causing global warming, the Biden administration is planning to use other regulatory tools in hopes of achieving similar goals. A key part of the plan: Further restrict other pollutants that coal-burning power plants emit such as soot, mercury and nitrous oxides — a move that also will reduce greenhouse gas emissions. ...White House officials said they believe President Biden’s goal of slashing emissions roughly in half by the end of this decade, and fully eliminating fossil fuel emissions from the power sector by 2035, still remains well within reach. The falling cost of renewable energy like wind and solar will help, administration officials said, as well as an increasing number of  policies at the state and local levels t

Arctic Shipping Routes Are Feeling the Heat

https://eos.org/articles/arctic-shipping-routes-are-feeling-the-heat By  Jenessa Duncombe , Eos/AGU.  Excerpt: Controversy over shipping routes in the Arctic Ocean is intensifying in light of recent climate science projections of sea ice melt. By midcentury, ice-free routes in international waters once covered by summer sea ice may appear for the first time in recent history, according to new research. A more accessible Arctic could influence the timing, sustainability, and legal status of international shipping. ... Sea ice extent may even influence the reach of international law: At present,  Article 234  of the United Nations Convention on the Law of the Sea grants coastal countries regulatory power over areas that are ice-covered for most of the year. Although opinions differ, some have said shrinking sea ice could limit countries’ claims in the Arctic Ocean. “There’s no scenario in which melting ice in the Arctic is good news,” said climate scientist  Amanda Lynch  from Brown Univ

Green hydrogen storage system project launched on NREL Colorado campus

https://www.energy-storage.news/green-hydrogen-storage-system-project-launched-on-nrel-colorado-campus/ By  Cameron Murray , Energy Storage News.  Excerpt: Hydrogen storage company GKN Hydrogen, gas utility SoCalGas and the US Department of Energy’s National Renewable Energy Laboratory are collaborating on a new green hydrogen storage solution. The three will work together to deploy two of GKN’s ‘HY2MEGA’ green hydrogen storage subsystems on NREL’s Flatirons Campus in Colorado, US. They will connect to an existing electrolyser and fuel cell at the ARIES (Advanced Research on Integrated Energy Systems) facility at Flatirons. The electrolyser will use renewable energy sources, possibly wind based on photos provided in the press release, to produce hydrogen for storage in GKN’s storage solution. HY2MEGA stores hydrogen in a solid state under low pressure, which can then be converted to produce electricity. The two systems will store a total of 500kgs of hydrogen on-site and GKN said its s

Methane much more sensitive to global heating than previously thought – study

https://www.theguardian.com/environment/2022/jul/05/global-heating-causes-methane-growth-four-times-faster-than-thought-study By Kate Ravilious , The Guardian.  Excerpt: Methane is four times more sensitive to global warming than previously thought, a new study shows. The result helps to explain the rapid growth in methane in recent years and suggests that, if left unchecked, methane related warming will escalate in the decades to come. The growth of this greenhouse gas – which over a 20 year timespan is more than 80 times as potent than carbon dioxide – had been slowing since the turn of the millennium but since 2007 has undergone a rapid rise, with  measurements from the US National Oceanic and Atmospheric Administration  recording it passing 1,900 parts a billion last year, nearly triple pre-industrial levels. ...About 40% of methane emissions come from natural sources such as wetlands, while 60% come from anthropogenic sources such as cattle farming, fossil fuel extraction and land

‘Every year it gets worse’: on the frontline of the climate crisis in Bangladesh

https://www.theguardian.com/environment/2022/jul/05/every-year-it-gets-worse-on-the-frontline-of-the-climate-crisis-in-bangladesh By  Thaslima Begum , The Guardian.  Excerpt: Over the past few weeks, catastrophic flash floods – the worst in  Bangladesh in a century  – have inundated much of Sylhet, where rising waters have washed away whole towns, killing at least 68 people and leaving thousands displaced. According to the UN, an estimated  7.2 million  people across seven districts have been affected. ...Humayara Jeba, 20, a climate fighter at YouthNet, the largest youth-led network for climate advocacy in Bangladesh, says women and girls are the most affected by the flooding because of their limited access to resources. “With high existing levels of poverty and inequality, climate change is intensifying the everyday challenges they already face,” she says. ...An estimated  60,000  women are pregnant in the affected region, with more than 6,500 births expected to take place in July.

Subverting Climate Science in the Classroom.

https://www.scientificamerican.com/article/subverting-climate-science-in-the-classroom/ ]  By Katie Worth , Scientific American, pp. 42-49.  Excerpt: Over the past two years school board meetings around the country have erupted into shout fests over face masks, reading lists and whether to ban  education about structural racism  in classrooms. In Texas, a quieter political agenda played out during the lightly attended process to set science education standards—guidelines for what students should learn in each subject and grade level. For the first time, the state board considered requiring that students learn something about human-caused  climate change . That requirement came under tense dispute between industry representatives interested in encouraging positive goodwill about fossil fuels and education advocates who think students should learn the science underlying the climate crisis unfolding around them. . . Last, Hickman moved to drop the climate mitigation standard that Pérez-Dí
