Apr 29 · For the last century, flamingos in Florida were more likely to be spotted on T-shirts and cups in a souvenir shop than flapping around in the wild.
Then last summer, a flock of the rare and beautiful birds - a group is fittingly known as a "flamboyance" of flamingos - was blown to Florida on the fierce winds of Hurricane Idalia.
Eight months later, they remain on the shores of Florida Bay, delighting scientists and inspiring hope that this could be the year they stick around for good.

| A new roadmap to close the carbon cycle - PHYS.ORG - Technology |
May 1 · Led by chemist Wendy Shaw of Pacific Northwest National Laboratory (PNNL), a multi-institutional effort has produced a new roadmap to reducing emissions in hard-to-electrify segments of the economy. The multifaceted approach includes developing non-carbon fuels, finding non-fossil sources of carbon, and keeping carbon in play once it enters the cycle, ideally resulting in multiple uses of each carbon atom.
Single-use carbon can no longer be widespread, the roadmap authors assert. The carbon must be kept in play through a circular economy where each carbon atom is used numerous times. The carbon can be reused within the same industrial sector or act as a feedstock for a new ... Read more ...

Apr 30 · However, Chinese cars are facing difficulties in finding buyers in Europe. Imported cars, many of which are Chinese electric vehicles, are piling up at European ports, with some spending up to 18 months in port car parks as manufacturers struggle to get them onto people's driveways.
Why is this, though? Chinese electric vehicles in particular are getting positive reviews. Having driven them myself, I can attest to them matching, or even exceeding, the well-known European brands in range, quality and technology.
But entering an established market as a challenger is a complex operation. Chinese makers will have to contend with buyer wariness, a lack of brand image, trade ... Read more ...

| Is bioenergy ever truly green? It depends on five key questions - PHYS.ORG - Technology |
May 1 · But is it environmentally sound? The annoying answer is: it depends.
Trees and other plants soak up carbon from the atmosphere and store it as biomass. When they are burnt for electricity production the same carbon is released. This would suggest bioenergy is "carbon-neutral."
But it's not that simple. Many things can change the environmental credentials of a bioenergy project. Every project is unique and must be considered independently.

| Jamie Raskin Names And Shames The 'Evil Fairy' Secretly Setting 'The Country Back' - Huffington Post |
May 2 · Rep. Jamie Raskin (D-Md.) slammed the petroleum industry on Wednesday as he pointed to experts who described Big Oil’s “pattern of lying and evasion” that has “set the country back decades” in its ability to address climate change.
“Instead of acting like Paul Revere and sounding the alarm about climate change, they acted like Maleficent the evil fairy and Sleeping Beauty and cursed everyone to try to go to sleep for 100 years,” said Raskin during a Senate Budget Committee hearing.
Raskin’s remarks arrived after that committee along with the House Oversight Committee released a 65-page report following a three-year investigation on oil and gas companies’ “evolving ... Read more ...

| Just 1,200 square kilometers of land could fulfill Australia's solar and wind energy needs - PHYS.ORG - Technology |
Apr 29 · So how much land is needed to fully decarbonize energy in Australia? When we switch completely to solar and wind, do we have the space for all the panels, turbines and power lines?
I've done the sums. All we need is 1,200 square kilometers. That's not much. The area devoted to agriculture is about 3,500 times larger at 4.2 million square kilometers. The area of land that would be taken away from agriculture works out at about 45 square meters per person—about the size of a large living room.
We can ditch fossil fuels and reduce greenhouse emissions with negligible impact on agriculture. And in many cases, farmers can be paid for hosting renewable energy ... Read more ...

| Kenya's devastating floods expose decades of poor urban planning and bad land management - PHYS.ORG - Earth |
May 1 · Floods are the natural consequence of storm rainfall and have an important ecological role. They inundate flood plains where silts settle, riverbed aquifers are recharged and nutrients are gathered. Annual rainfall in Kenya varies from 2,000 mm in the western region to less than 250 mm in the drylands covering over 80% of Kenya. But storm rainfalls are widespread. This means that floods can occur in any part of the country.
The impact of floods has become more severe due to a number of factors.
The first is how much water runs off. In rural areas, changes to the landscape have meant that there's been an increase in the amount of storm runoff generated from rainfall. This ... Read more ...

| Measuring your food waste for six weeks can change your habits, according to new study - PHYS.ORG - Earth |
Apr 30 · The fact that there is often little or no conscious thought involved in routine daily food preparation means that ingredients that must be used before they expire are often left to go off.
Every year, 1.3 billion tons of food is wasted globally. This is the equivalent of one-third of all the food produced for human consumption.
In the UK alone, households wasted 6.4 million tons of food between 2021 and 2022. Accounting for the fossil energy used to grow and harvest that food, as well as the greenhouse gases released when it rots in fields or landfills, this waste equates to 18 million tons of CO₂ emissions.

| New computer algorithm supercharges climate models and could lead to better predictions of future climate change - PHYS.ORG - Earth |
May 1 · However, climate modelers have long faced a major problem. Because Earth System Models integrate many complicated processes, they cannot immediately run a simulation; they must first ensure that it has reached a stable equilibrium representative of real-world conditions before the industrial revolution. Without this initial settling period—referred to as the "spin-up" phase—the model can "drift," simulating changes that may be erroneously attributed to manmade factors.
Unfortunately, this process is extremely slow as it requires running the model for many thousands of model years which, for IPCC simulations, can take as much as two years on some of the world's most ... Read more ...

Tests carried out by a German laboratory revealed the presence of bird flu, Lydersen said. The sample was too small to determine whether it was the H5N1 or the H5N8 strain.
"It is the first time that bird flu has been recorded in a walrus," Lydersen said.
About six dead walrus were found last year in the Svalbard islands, about 1,000 kilometers (620 miles) from the North Pole and halfway between ... Read more ...

| Water Heaters Use Lots of Energy. The D.O.E. Wants to Change That. - New York Times - Climate Section |
Apr 30 · The Biden administration is tightening efficiency rules for water heaters, stoves and other appliances, and conservative politicians are dialing up their criticisms.
The Biden administration on Tuesday adopted stricter energy-efficiency standards for residential water heaters, the most consequential move in a flurry of changes designed to reduce the energy used by many common appliances including stoves, dishwashers and lightbulbs.
The Department of Energy said the new standards, taken together, will save American households and businesses nearly $1 trillion over 30 years, and save the average family $100 a year or more through lower utility bills. The changes will also ... | By Hiroko Tabuchi Read more ...

| We must examine the connection between packaging and climate change - Greenbiz |
Apr 30 · Companies should think more holistically about the link between packaging and carbon.
What’s contributing to climate change? Everyone can probably name a few of the culprits: how we get around; how we produce energy; and maybe what we eat. Less top of mind? The things we buy, including what they’re made out of and how they’re packaged.
For companies wanting to decarbonize, focusing solely on energy can stall efforts to tackle equally important sources of emissions. A 2019 report by Material Economics and the Ellen MacArthur Foundation (EMF) calculated that "materials" (defined as aluminum, plastic, cement, steel and food) account for 45 percent of global emissions. That ... | By Olga Kachook Read more ...

Apr 24 · An international team of researchers has successfully used NASA's James Webb Space Telescope to map the weather on the hot gas-giant exoplanet WASP-43 b.
Precise brightness measurements over a broad spectrum of mid-infrared light, combined with 3D climate models and previous observations from other telescopes, suggest the presence of thick, high clouds covering the nightside, clear skies on the dayside, and equatorial winds upwards of 5,000 miles per hour mixing atmospheric gases around the planet.
The investigation is just the latest demonstration of the exoplanet science now possible with Webb's extraordinary ability to measure temperature variations and detect ... Read more ...

| What a years-long probe of Big Oil reveals about its climate strategy - Washington Post - Climate and Environment |
Apr 30 · Some of the world’s largest oil companies have privately expressed skepticism of the Paris agreement, federal climate regulations and their own goals of reaching “net zero” emissions by mid-century, even as they publicly voiced support for these efforts, according to documents that congressional Democrats released Tuesday.
The documents also detail industry efforts to fund university research into the environmental benefits of natural gas. They were obtained by Democrats on the House Oversight and Accountability Committee and the Senate Budget Committee as part of a years-long investigation. Read more ...

The Environmental Protection Agency (EPA) released new rules Thursday that require newly built natural gas power plants to cut 90 percent of their emissions by 2032, and existing fossil fuel-run power plants will have to comply or exit the grid by 2039.
To reach this goal, utilities will have to invest in carbon capture and sequestration/storage (CCS) technologies, something EPA administrator Michael Regan believes is financially feasible.

| Wild bees are under threat from domestic bees, invasive species, pathogens and climate change - but we can help - PHYS.ORG - Biology |
Apr 30 · With changes in climate, habitat loss, pesticide use and pathogen spillover, some of our native bees are in decline.
The vast majority of wild bee species are rare. More than 200 species live in the habitat-rich forests, fields and neighborhoods around Hamilton and McMaster University, where they are the subjects of our research.
In Ontario, there are many different types of bees, including bumblebees, carder bees, carpenter bees, cellophane bees, cuckoo bees, leaf cutter bees, long horned bees, mason bees, mining bees, sweat bees and yellow-faced bees.
Many of our wild bees are solitary, highly specialized and transient from one year to the next. This makes them ... Read more ...

| Wondering what Australia might look like in a hotter world? Take a glimpse into the distant past - PHYS.ORG - Earth |
May 1 · Wouldn't it be useful to go back in time and see what Australia looked like during those periods in the distant past? Well, scientists—including us—have done just that.
These studies, which largely involve examining sediments and fossils, reveal a radically different Australia to the one we inhabit.
The continent was warmer and wetter, and filled with unfamiliar plant and animal species. It suggests Australia may be much wetter, and look very different, in centuries and millennia to come.
Then and now: Measuring CO₂
Atmospheric CO₂ is measured in "parts per million"—in other words, how many CO₂ molecules are present in each ... Read more ...

Apr 29 · The flight deck of a decommissioned World War II-era aircraft carrier docked at Alameda has recently begun launching something other than airplanes: microscopic droplets of salt water that scientists hope will help counteract the effects of climate change.
A team of atmospheric scientists from the University of Washington has teamed up with Silicon Valley-based Stanford Research Institute, an independent nonprofit research facility, and SilverLining, a nonprofit focused on near-term climate risks, to study whether adding plumes of salt water to a cloud will make it more reflective and stop excess heat from reaching the Earth's surface.
Cloud brightening is an idea first ... Read more ...
