The European Space Agency appears to have a slight problem: a critical antenna is jammed on their Jupiter-bound spacecraft launched two weeks ago. From the Associated Press: The 52-foot (16-meter) radar antenna on Juice unfolded only one-third of the way following liftoff, according to the space agency. Engineers suspect a tiny pin may be protruding. Flight controllers in Germany plan to fire the spacecraft's engine in hopes of shaking the pin loose. If that doesn't work, they said they have plenty of time to solve the problem.

Juice, short for Jupiter Icy Moons Explorer, won't reach the giant planet until 2031. It's taking a roundabout path to get there, including gravity-assist flybys of Earth and our moon, and Venus. The radar antenna is needed to peer beneath the icy crust of three Jupiter moons suspected of harboring underground oceans and possibly life, a major goal of the nearly $1.8 billion mission. Its targets include Callisto, Europa and Ganymede, the largest moon in the solar system.

An anonymous reader quotes a report from The Hacker News: Google on Wednesday said it obtained a temporary court order in the U.S. to disrupt the distribution of a Windows-based information-stealing malware called CryptBot and "decelerate" its growth. The tech giant's Mike Trinh and Pierre-Marc Bureau said the efforts are part of steps it takes to "not only hold criminal operators of malware accountable, but also those who profit from its distribution." CryptBot is estimated to have infected over 670,000 computers in 2022 with the goal of stealing sensitive data such as authentication credentials, social media account logins, and cryptocurrency wallets from users of Google Chrome. The harvested data is then exfiltrated to the threat actors, who then sell the data to other attackers for use in data breach campaigns. CryptBot was first discovered in the wild in December 2019.

The malware has been traditionally delivered via maliciously modified versions of legitimate and popular software packages such as Google Earth Pro and Google Chrome that are hosted on fake websites. [...] The major distributors of CryptBot, per Google, are suspected to be operating a "worldwide criminal enterprise" based out of Pakistan. Google said it intends to use the court order, granted by a federal judge in the Southern District of New York, to "take down current and future domains that are tied to the distribution of CryptBot," thereby kneecapping the spread of new infections.

Climate scientists already know that the East Coast of the United States could see around a foot of sea-level rise by 2050, which will be catastrophic on its own. But they are just beginning to thoroughly measure a "hidden vulnerability" that will make matters far worse: The coastline is also sinking. From a report: It's a phenomenon known as subsidence, and it's poised to make the rising ocean all the more dangerous, both for people and coastal ecosystems. New research published in the journal Nature Communications finds that the Atlantic coast -- home to more than a third of the US population -- is dropping by several millimeters per year. In Charleston, South Carolina, and the Chesapeake Bay, it's up to 5 millimeters (a fifth of an inch). In some areas of Delaware, it's as much as twice that. Five millimeters of annual sea-level rise along a stretch of coastline, plus 5 millimeters of subsidence there, is effectively 10 millimeters of relative sea-level rise.

Atlantic coastal cities are already suffering from persistent flooding, and the deluge will only get worse as they sink while seas rise. Yet high-resolution subsidence data like this isn't yet taken into account for coastal hazard assessments. "What we want to do here is to really bring awareness about this missing component, that based on our analysis actually makes the near-future vulnerability a lot worse than what you would expect from sea-level rise alone," says Manoochehr Shirzaei, an environmental security expert at Virginia Tech and coauthor of the new paper.

SpaceX and Rogers Communications struck a deal for satellite phone service in Canada -- a bid to bring emergency service to remote areas of the vast country that can't be reached through conventional wireless networks. From a report: The companies will use SpaceX's Starlink low-earth orbit satellites and begin with text service before adding voice and data coverage later, Rogers said in a statement. It didn't give a launch date for the new service. "In the future, these investments will deliver wireless connectivity, including access to 911, to even the most remote areas," Rogers Chief Executive Officer Tony Staffieri said in a statement. Staffieri was due to speak about the arrangement during his speech at the company's annual meeting on Wednesday.

A group of venture capital firms including Tiger Global and Union Square Ventures on Tuesday set up an alliance aimed at making private tech investing more climate-friendly. From a report: Called the Venture Climate Alliance (VCA), the coalition of more than 20 climate tech and generalist funds seeks to get the VC industry to increase its commitments to climate tech, a branch of technology devoted to finding solutions to the climate crisis. The alliance lays out guidance that its VC members and their portfolio companies must follow to ensure they meet the requirements to achieve net-zero emissions by 2050.

According to a statement, the VCA's stated aim is to "ensure that methodology and metrics are at the heart of how we determine what is a good climate investment, and what investment will have the greatest positive effect on the mission to build tech for a regenerative world." Portfolio companies are given guidance on how they should decarbonize their operations, such as using emission-free data centers, deploying less energy-intensive software in their tech stack, or rebuilding supply chains around low-carbon alternatives, the statement said. Other funds signed up to the VCA include climate VCs World Fund, 2150, and Prelude Venture. Collectively, the investment firms involved manage a combined $62.3 billion in assets, according to Crunchbase figures. [...] The U.N. approved the VCA as part of its Race to Zero campaign aimed at mobilizing climate action. The alliance will fall under the Glasgow Financial Alliance for Net Zero (GFANZ), a group formed during the COP26 climate conference.

Canadian singer-songwriter Grimes has invited her fans to create music using her voice, stating that she would split 50% of royalties for any successful AI-generated song using her voice. On Sunday night she tweeted: "I'll split 50% royalties on any successful AI generated song that uses my voice. Same deal as I would with any artist i collab with. Feel free to use my voice without penalty. I have no label and no legal bindings."

She also said she welcomes the open sourcing of art and an end to copyright. "Im just curious what even happens and interested in being a Guinea pig." From a report: Grimes has long embraced AI as a techno artist. In 2020, her first album to top the Billboard dance charts was Miss Anthropocene, named for the effects of technology on Earth's ecology and climate in the post-Industrial Revolution era. It was also in 2020 that she teamed up with the algorithmic mood music startup Endel to create an AI-generated lullaby for her first child with SpaceX founder Elon Musk who they named X AE A-12 with the Elven spelling of AI, according to Grimes.

"Everyday I thank the overlords of Ableton for cleaning up my tracks, but I do worry though that AI will outpace us and make musicians obsolete. It's inevitable," she warned at Web Summit 2020. With millions of followers across YouTube, Instagram and Twitter and hits like Oblivion, Kill V. Maim and Go, her call for AI collaboration could be a game changer.

Alexander De Croo (the prime minister of Belgium), Mark Rutte (the prime minister of the Netherlands), Xavier Bettel (the prime minister of Luxembourg), Emmanuel Macron (the president of France), Olaf Scholz (the chancellor of Germany), Leo Varadkar (the prime minister of Ireland), Jonas Gahr Store (the prime minister of Norway), Rishi Sunak (the prime minister of the United Kingdom), and Mette Frederiksen (the prime minister of Denmark), writing at Politico: We need offshore wind turbines -- and we need a lot of them. We need them to reach our climate goals, and to rid ourselves of Russian gas, ensuring a more secure and independent Europe. Held for the first time last year, Denmark, Germany, Belgium and the Netherlands came together for the inaugural North Sea Summit in the Danish harbor town of Esbjerg, setting historic goals for offshore wind with the Esbjerg Declaration. It paved the way for making the North Seas a green power plant for Europe, as well as a major contributor to climate neutrality and strengthening energy security.

This Monday, nine countries will meet for the next North Sea Summit -- this time in the Belgian town of Ostend -- where France, Ireland, Luxembourg, Norway and the United Kingdom will also put their political weight behind developing green energy in the North Seas, including the Atlantic Ocean and the Irish and Celtic Seas. Together, we will combine and coordinate our ambitions for deploying offshore wind and developing an offshore electricity grid, putting Europe on the path toward a green economy fueled by offshore green power plants. Collectively, our target for offshore wind in the North Seas is now 120 gigawatts by 2030, and a minimum of 300 gigawatts by 2050 -- larger than any of the co-signatories' existing generation capacity at a national level. And to deliver on this ambition, we are committing to building an entire electricity system in the North Seas based on renewable energy by developing cooperation projects.

This is a massive undertaking and a true example of the green transition in the making. It also requires huge investments in infrastructure, both offshore and on land. It presents us with a political and environmental dilemma as well: We are facing a climate crisis at the same time some of our ecosystems are in decline, and offshore wind is an integral part of both climate action and safeguarding our energy security. Thus, time is of the essence, and we must follow up on the progress already made on reining in the burden of bureaucracy for renewable projects.

The Associated Press visited a 100-foot barge moored in Los Angeles where engineers built "a kind of floating laboratory to answer a simple question: Is there a way to cleanse seawater of carbon dioxide and then return it to the ocean so it can suck more of the greenhouse gas out of the atmosphere to slow global warming?" The technology, dubbed SeaChange, developed by the University of California Los Angeles engineering faculty, is meant to seize on the ocean's natural abilities, said Gaurav Sant, director of UCLA's Institute for Carbon Management. The process sends an electrical charge through seawater flowing through tanks on the barge. That then sets off a series of chemical reactions that trap the greenhouse gas into a solid mineral that includes calcium carbonate — the same thing seashells are made of. The seawater is then returned to the ocean and can pull more carbon dioxide out of the air. The calcium carbonate settles to the sea floor.

Plans are now underway to scale up the idea with another demonstration site starting this month in Singapore. Data collected there and at the Port of Los Angeles will help in the design of larger test plants. Those facilities are expected to be running by 2025 and be able to remove thousands of tons of CO2 per year. If they are successful, the plan is to build commercial facilities to remove millions of tons of carbon annually, Sant said...

Scientists estimate at least 10 billion metric tons of carbon will need to be removed from the air annually beginning in 2050, and the pace will need to continue over the next century... According to the UCLA team, at least 1,800 industrial-scale facilities would be needed to capture 10 billion tons of atmospheric carbon dioxide per year, but fewer could still make a dent.
The article notes alternate ideas from other researchers — including minerals on beaches that increase the ocean's alkalinity so it can absorb more carbon dioxide.

But this SeaChange process also produces hydrogen. So the director of UCLA's Carbon Management institute also founded a startup that generates revenue from that hydrogen (and from "carbon credits" sold to other companies) — hoping to lower the cost of removing atmospheric carbon to below $100 per metric ton.

CNN reports on this year's "State of the Climate" report from the World Meteorological Organization (the UN agency promoting international cooperation on atmospheric science a d climatology).

The report "analyzes a series of global climate indicators — including levels of planet-heating pollution, sea level rise and ocean heat — to understand how the planet is responding to climate change and the impact it is having on people and nature."

CNN's conclusion? "The world just failed its annual health checkup."= - Oceans reached record high temperatures, with nearly 60% experiencing at least one marine heatwave.

- Global sea levels climbed to the highest on record due to melting glaciers and warming oceans, which expand as they heat up.

- Antarctica's sea ice dropped to 1.92 million square kilometers in February 2022, at the time the lowest level on record (the record was broken again this year).

- The European Alps saw a record year for glacier melt, with Switzerland particularly badly affected, losing 6% of its glacier volume between 2021 and 2022.

- Levels of planet warming pollution, including methane and carbon dioxide, reached record highs in 2021, the latest year for which there is global data...


Last year, climate change-fueled extreme weather "affected tens of millions, drove food insecurity, boosted mass migration, and cost billions of dollars in loss and damage," WMO Secretary-General Petteri Taalas said in a statement. In 2022, China had its most extensive and long-lasting drought on record. Droughts also affected East Africa, with more than 20 million people in Ethiopia, Kenya and Somalia facing acute food insecurity as of January this year. Many western and southern US states experienced significant drought and Europe's punishing heatwave is estimated to have led to 15,000 excess deaths. In Pakistan, record-breaking rainfall left huge swaths of the country underwater, killing more than 1,700 people, with almost 8 million displaced, and causing $30 billion in damages...

Last year is unlikely to be an outlier, as temperatures continue their upwards trajectory. The past eight years were the hottest on record, despite three consecutive years of the La Niña climate phenomenon, which has a global cooling effect. The global average temperature last year climbed to about 1.15 degrees Celsius above pre-industrial levels, according to the report, as the world continues its march towards breaching 1.5 degrees of warming for the first time. With the predicted arrival later in the year of El Niño, which brings warmer global temperatures, scientists are deeply concerned that 2023 and 2024 will continue to smash climate records. The hottest year on record, 2016, was the result of a strong El Niño and climate change, said Baddour. "It is only a matter of time before that record is broken...."

"The droughts and level of heatwaves that we saw throughout 2022 were quite remarkable," Samantha Burgess, deputy director of Copernicus, told CNN. "This is really a wake up call that climate change isn't a future problem, it is a current problem. And we need to adapt as quickly as possible," she added.
Omar Baddour, head of the Climate Monitoring and Policy Division at the WMO, also told CNN that "Communities and countries which have contributed least to climate change suffer disproportionately."

And for more bad news, CNN notes a report from the European Union's Copernicus Climate Change Service found Europe experienced its hottest summer ever recorded, unprecedented marine heatwaves in the Mediterranean sea, and widespread wildfires.

The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Phys.Org reports: Using 50 different satellite estimates, researchers found that Greenland's melt has gone into hyperdrive in the last few years. Greenland's average annual melt from 2017 to 2020 was 20% more a year than at the beginning of the decade and more than seven times higher than its annual shrinkage in the early 1990s. From 1992 to 1996, the two ice sheets -- which hold 99% of the world's freshwater ice -- were shrinking by 116 billion tons (105 billion metric tons) a year, two-thirds of it from Antarctica. But from 2017 to 2020, the newest data available, the combined melt soared to 410 billion tons (372 billion metric tons) a year, more than two-thirds of it from Greenland, said the study in Thursday's journal Earth System Science Data.

Since 1992, Earth has lost 8.3 trillion tons (7.6 trillion metric tons) of ice from the two ice sheets, the study found. That's enough to flood the entire United States with 33.6 inches (almost 0.9 meters) of water or submerge France in 49 feet (nearly 15 meters). But because the world's oceans are so huge, the melt just from the ice sheets since 1992 still only adds up to a little less than inch (21 millimeters) of sea level rise, on average. Globally sea level rise is accelerating and melt from ice sheets has gone from contributing 5% of the sea level rise to now accounting for more than one-quarter of it, the study said. The rest of the sea rise comes from warmer water expanding and melt from glaciers.

An anonymous reader quotes a report from the New York Times: President Biden on Thursday will pledge $500 million over five years to fight deforestation in Brazil, a White House official said, in a move that would make the United States one of the largest donors to the global Amazon Fund. But the pledge would require approval from Congress, where Republicans are overwhelmingly opposed to international climate assistance and have made it difficult for President Biden to deliver on his promises to help poorer nations cope with climate change. Brazil's president, Luiz Inacio Lula da Silva, has been working with the Biden administration on several issues, including climate change, despite Mr. Lula's criticism of U.S. support for Ukraine in its war with Russia.

The Amazon Fund, a conservation program, was established by Brazil in 2008 and has bankrolled efforts to curb deforestation in the world's largest rainforest. Norway, the first and largest contributor to the fund, has donated more than $1.2 billion. Germany recently announced a $217 million donation. But the fund was suspended under Mr. Lula's far-right predecessor, Jair Bolsonaro, who weakened environmental protections and saw annual average deforestation rates soar, reaching levels the country hadn't experienced in more than a decade.

A NASA satellite that observed solar flares and helped scientists understand the sun's powerful bursts of energy will fall to Earth this week, almost 21 years after it was launched. CNN reports: The retired Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) spacecraft, which launched in 2002 and was decommissioned in 2018, is expected to reenter Earth's atmosphere Wednesday at approximately 9:30 p.m. ET, according to NASA. The spacecraft was equipped with an imaging spectrometer, which recorded the sun's X-rays and gamma rays. From its former perch in low-Earth orbit, the satellite captured images of high-energy electrons that carry a large part of the energy released in solar flares, NASA said.

Before RHESSI, no gamma-ray images or high-energy X-ray images had been taken of solar flares, and data from the spacecraft provided vital clues about the phenomena and their associated coronal mass ejections. [...] NASA said that the agency, along with the Department of Defense, would monitor the satellite's reentry into Earth's atmosphere.

From China to the U.S. to the European Union, rice production is falling and driving up prices for more than 3.5 billion people across the globe, particularly in Asia-Pacific -- which consumes 90% of the world's rice. From a report: The global rice market is set to log its largest shortfall in two decades in 2023, according to Fitch Solutions. And a deficit of this magnitude for one of the world's most cultivated grains will hurt major importers, analysts told CNBC. "At the global level, the most evident impact of the global rice deficit has been, and still is, decade-high rice prices," Fitch Solutions' commodities analyst Charles Hart said. Rice prices are expected to remain notched around current highs until 2024, stated a report by Fitch Solutions Country Risk & Industry Research dated April 4.

The price of rice averaged $17.30 per cwt through 2023 year-to-date, and will only ease to $14.50 per cwt in 2024, according to the report. Cwt is a unit of measurement for certain commodities such as rice. "Given that rice is the staple food commodity across multiple markets in Asia, prices are a major determinant of food price inflation and food security, particularly for the poorest households," Hart said. The global shortfall for 2022/2023 would come in at 8.7 million tonnes, the report forecast. That would mark the largest global rice deficit since 2003/2004, when the global rice markets generated a deficit of 18.6 million tonnes, said Hart. Further reading: There is a Global Rice Crisis.

An anonymous reader shares a report: We know from natural events in the past that increasing the amount of iron in these seas can dramatically increase the growth of phytoplankton. When iron-rich ash from volcanic eruptions has fallen on the ocean's surface, it has triggered phytoplankton blooms large enough to see from space. This knowledge led oceanographer John Martin to put forth something called the "iron hypothesis," which suggests that "fertilizing" the ocean with iron could increase the amount of carbon-sucking phytoplankton -- theoretically enough to cool the entire Earth. "Give me a half tanker of iron, and I will give you an ice age," he famously quipped during a lecture in 1988.

In 1993, shortly after Martin's death, his colleagues at Moss Landing Marine Laboratories tested the hypothesis by increasing the concentration of iron over 64 square kilometers of the Pacific Ocean. They then observed the area for 10 days and saw the amount of plant biomass double. "All biological indicators confirmed an increased rate of phytoplankton production in response to the addition of iron," they wrote in a paper detailing the experiment. More than a dozen other ocean fertilization experiments have been conducted since then, but even though they do appear to cause a bloom of plankton, it's still not clear whether the approach could actually help combat climate change.

In 2009, researchers from the Department of Energy's Lawrence Berkeley National Laboratory tracked the impact of a major ocean fertilization experiment in the Southern Ocean between New Zealand and Antarctica by measuring carbon particles 800 meters below the surface of the water in the area for a year -- and their findings were less than encouraging. "Just adding iron to the ocean hasn't been demonstrated as a good plan for storing atmospheric carbon," said researcher Jim Bishop. "What counts is the carbon that reaches the deep sea, and a lot of the carbon tied up in plankton blooms appears not to sink very fast or very far." While researchers are still trying to figure out why that is, there are a number of theories, including ones centered on the feeding habits of creatures that live off phytoplankton and the presence of iron-binding organic compounds in ocean water.

India lost 668,400 hectares of jungles on average between 2015 and 2020, a new report has said. From a report: The is only second to the scale of deforestation in Brazil, noted the report released last month by Utility Bidder, a UK-based utility costs comparison firm. Brazil lost nearly 1.7 million hectares of forest between 2015-2020, as climate change adversely affected forest growth. Utility Bidder's report analyzed deforestation trends in 98 countries over the past 30 years. "As the country with the second largest population in the world, India has had to compensate for the increase in residents -- this has come at a cost in the way of deforestation," the report stated. Since prime minister Narendra Modi came to power in 2014, his government has given an impetus to stalled projects approved under his predecessor, besides launching fresh ones. For this, vast areas of forestry needed to be cleared.

An anonymous reader quotes a report from Ars Technica: A survey of plastic waste picked up in the North Pacific Subtropical Gyre -- aka the Giant Pacific Garbage Patch -- has revealed that the garbage is providing a home to species that would otherwise not be found in the deep ocean. Over two-thirds of the trash examined plays host to coastal marine species, many of which are clearly reproducing in what would otherwise be a foreign habitat. The findings suggest that, as far as coastal species are concerned, there was nothing inhospitable about the open ocean other than the lack of something solid to latch on to. [...]

Plastics, especially things like buoys, floats, and netting, are often designed to hold up in the difficult marine environment and could provide a stable home at the top of the water column. To find out whether that was taking place, the researchers collected over 100 plastic debris items from the North Pacific Subtropical Gyre in late 2018/early 2019. While a handful of items could be assigned to either Asian or North American origins, most were pretty generic, such as rope and fishing netting. There was a wide variety of other items present, including bottles, crates, buckets, and household items. Some had clearly eroded significantly since their manufacture, suggesting they had been in the ocean for years. Critically, nearly all of them had creatures living on them.

Ninety-eight percent of the items found had some form of invertebrate living on them. In almost all cases, that included species found in the open ocean (just shy of 95 percent of the plastic). But a handful had nothing but coastal species present. And over two-thirds of the items had a mixed population of coastal and open-ocean species. While the open-ocean species were found on more items, the researchers tended to find the same species repeatedly. All told, coastal species accounted for 80 percent of the 46 taxonomic richness represented by the organisms identified. Significantly, the coastal species were breeding. In a number of cases, the researchers were able to identify females carrying eggs; in others, it was clear that the individuals present had a wide range of sizes, suggesting they were at different stages of maturity. "One thing that struck the researchers was that the list of species present on the plastic of the North Pacific Subtropical Gyre was distinct from that found on tsunami debris," adds the report. "Part of that may be that some items swept across the ocean by the tsunami, like docks and boats, already had established coastal communities on them when they were lost to the sea."

The findings were published in the journal Nature Ecology & Evolution.

Utah's Great Salt Lake had shrunk by two thirds its original size, the New York Times reported last June. And "It was only three months ago that nearly three dozen scientists and conservationists sounded the alarm that the Great Salt Lake in Utah faces 'unprecedented danger'," CNN reports. "Unless the state's lawmakers fast-tracked 'emergency measures' to dramatically increase the lake's inflow by 2024, it would likely disappear in the next five years." Now, after an incredible winter full of rain and snow, there is a glimmer of hope on North America's largest terminal lake, where water levels had fallen to a record-low last fall amid a historic, climate change-fueled drought across the West. As of Thursday, the snowpack in the Great Salt Lake basin was more than double the average for this time of year. All of this winter's rain and snow that fell directly into the Great Salt Lake increased the water level there by three feet...

In reality, the precipitation only made up for what was lost to last year's drought and evaporation... To reverse the decline, the Great Salt Lake needs an additional 1 million acre-feet of water — roughly 326 billion gallons — per year, according to the January assessment. Bonnie Baxter, the director of the Great Salt Lake Institute at Westminster College and one of the authors of the January report, said the state would "need another five years like this in order to get the system healthy again."

"If I do the math, we got about three feet of direct precipitation that fell into the lake this year, that is fantastic," Baxter told CNN. "But the last two years, we also lost 2.8 feet in the summer, and we expect to lose that three feet in the desiccating summer. So now, we're pretty much even, and that's not a good place to be."
Baxter says the rainfall "buys us some time" to work on long-term issues like water rights and metering the water used in agriculture — maybe a year or two — but "We're not going to be bailed out by excess snow."

There's hope melting snow could add more water, but Baxter warns that it might not. "If it melts really quickly, which is probably going to happen because we have these late snows and now we're right up against warm temperatures, then you get the water just rushing over the land and not taking time to charge the aquifers and just evaporating off the surface."

"The abundant sun of northern Africa may soon power Europe's homes and businesses," reports the Washington Post, "as European leaders consider connecting massive North African solar projects to undersea power cables to free their continent from Russian energy." The projects would take advantage of the climate quirk that one side of the Mediterranean is far drearier and cloudier than the other, although Europe and North Africa are geographically close. Abundant desert land also makes North African megaprojects far easier than in Europe, where open spaces tend to be agricultural or mountainous. The sudden need for alternative energy following Russia's invasion of Ukraine means that North African solar projects intended to send electricity to Europe are under active discussion, officials and experts say, as European leaders see a straightforward way to secure large amounts of green power. Past proposals have suggested that North African energy projects could meet as much as 15 percent of Europe's electricity demand.

The interest is especially high in Morocco, where undersea electrical cables already cross the 10-mile span to Spain at the Strait of Gibraltar. Moroccan leaders — who never had any fossil fuels to export — see a chance to promote their country as a renewable energy giant. Europe, meanwhile, wants to hit its ambitious climate goals and address its need for non-Russian energy at the same time. The result is a confluence of interests that could lead to a sudden leap forward for Europe's renewable energy uptake.

More broadly, it is a test for the concept of shipping green energy from sunny parts of the world to regions where the sun doesn't shine as brightly.... Europe alone doesn't have "the potential for the scale to create the dimensions of the renewable energy that we need," said European Commission Vice President Frans Timmermans, speaking alongside Moroccan Foreign Minister Nasser Bourita.
The article cites estimates from the International Renewable Energy Agency that North Africa's "installable capacity" is 2,792 gigawatts of solar power and 223 gigawatts of wind power. Laura El-Katiri, a fellow at the European Council on Foreign Relations who specializes in North African renewable energy, writes that could generate more than two and a half times Europe's 2021 electricity output.

Virginia Norwood, an aerospace pioneer who invented the scanner that has been used to map and study the earth from space for more than 50 years, has died at her home in Topanga, Calif. She was 96. The New York Times reports: Her death was announced by the United States Geological Survey, whose Landsat satellite program relies on her invention. Her daughter, Naomi Norwood, said her mother was found dead in her bed on the morning of March 27. The Landsat satellites, speeding 438 miles above the surface, orbit the earth every 99 minutes and have captured a complete image of the planet every 16 days since 1972. These images have provided powerful visual evidence of climate change, deforestation and other shifts affecting the planet's well-being.

Ms. Norwood, a physicist, was the person primarily responsible for designing and championing the scanner that made the program possible. NASA has called her "the mother of Landsat." At the dawn of the era of space exploration in the 1950s and '60s, she was working at Hughes Aircraft Company developing instruments. One of a small group of women in a male-dominated industry, she stood out more for her acumen. "She said, 'I was kind of known as the person who could solve impossible problems,'" Naomi Norwood told NASA for a video on its website. "So people would bring things to her, even pieces of other projects." [...]

Over the next 50 years, new Landsat satellites replaced earlier ones. Ms. Norwood oversaw the development of Landsat 2, 3, 4 and 5. Currently, Landsat 8 and 9 are orbiting the earth, and NASA plans to launch Landsat 10 in 2030. Each generation satellite has added more imaging capabilities, but always based on Ms. Norwood's original concept. The Landsat program has mapped changes in the planet brought on by climate change and by human actions. They include the near disappearance of the Aral Sea between Kazakhstan and Uzbekistan, the shrinking of the Great Salt Lake in Utah, the evolving shape of the Mississippi Delta, and the deforestation and increasing agricultural use of land in Turkey and Brazil.

The official in charge of a secretive Pentagon effort to investigate unexplained aerial incursions has co-authored an academic paper that presents an out-of-this-world theory: Recent objects could actually be alien probes from a mothership sent to study Earth. Politico reports: In a draft paper dated March 7 (PDF), Sean Kirkpatrick, head of the Pentagon's All-domain Anomaly Resolution Office, and Harvard professor Avi Loeb teamed up to write that the objects, which appear to defy all physics, could be "probes" from an extraterrestrial "parent craft." It's unusual for government officials, especially those involved in the nascent effort to collect intelligence on recent sightings, to discuss the possibility of extraterrestrial life, although top agency officials don't rule it out when asked. After Loeb posted it online, the paper gained notoriety from a post on Military Times and has also circulated among science-focused news outlets.

More than half of the five-page paper is devoted to discussing the possibility that the unexplained objects DoD is studying could be the "probes" in the mothership scenario, including most of the page-long introduction. One section is titled: "The Extraterrestrial Possibility" and another "Propulsion Methods." Kirkpatrick's involvement in the academic paper demonstrates that the Pentagon is open to scientific debate of the origins of UFOs, an important signal to send to the academic world, experts said. But they add that his decision to attach his name to a theory considered in most academic circles to be highly unsubstantiated also raises questions about AARO's credibility.

The paper explains that interstellar objects such as the cigar-shaped "Oumuamua" that scientists spotted flying through the galaxy in 2017 "could potentially be a parent craft that releases many small probes during its close passage to Earth." The paper goes on to compare the probes to "dandelion seeds" that could be separated from the parent craft by the sun's gravitational force. It examines the physics of how the smaller craft could move through the Earth's atmosphere to reach the surface, where they could be spotted by humans. The paper notes that the "probes" could use starlight to "charge their batteries" and the Earth's water as fuel. It also speculates on the motive for aliens to send exploratory probes to Earth. "What would be the overarching purpose of the journey? In analogy with actual dandelion seeds, the probes could propagate the blueprint of their senders," the authors write. "As with biological seeds, the raw materials on the planet's surface could also be used by them as nutrients for self-replication or simply scientific exploration."
