Sustainability culture and rebuilding consensus on environmental policy

by Steve Cohen, State of the Planet

As bad as things are this year, I confess that I remain an optimist and believe we will figure out the crises we now confront and make the world less bad than it is today. COVID-19, climate, equity, racism and poverty are real and daunting public policy problems. There are crazy people in the world that want to kidnap governors, kill a man with a relentless knee to his neck, party without masks, and don't think that COVID-19 and climate change are real. But most people see the world as it is, and I find people generous and typically willing to help those in need. A growing number of people worry about our planet becoming contaminated and want to ensure their behavior doesn't make things worse.


The importance of protecting our air, land and water is a shared value. Polluters develop elaborate excuses and rationalizations to defend their pollution because they know that harming the environment is a bad thing and most people see the world that way. The polluters themselves see the world that way- they can't help sharing those values. There is this nagging feeling in the back of our mind that the world is getting more crowded and the resources we once relied on are not always available. The well we dug when we first moved into our home is now contaminated and we need to pay to pipe in filtered "city water." The quiet country road we drove on when we were kids is now a highway. The woods we used to camp in were ripped out to build a strip mall. The Not in My Backyard syndrome or "NIMBY" comes from a desire to preserve current land uses and prevent new ones that might change a status quo we are often eager to maintain. We are told that there is a trade-off between economic wealth and environmental protection, but if there is a trade-off, we don't feel good about it. I should note that I consider this a false trade-off and that economic development that damages the environment brings short-term benefits at the expense of much greater long-term costs. And the costs can be avoided with ingenuity, scientific analysis and carefully considered actions.

We don't want to be regulated and told what to do but we also don't want other people to contaminate the air, land and water we rely on. We don't want to do without modern conveniences like autos, jets and air conditioners, but we sure wish we could have that stuff without damaging our planet. The ethical value of environmental protection is one that is widely shared. At the start of the environmental movement in the 1960s, the issues were easier to understand. Residents of Los Angeles could see and smell the smog. Orange rivers that caught fire were obviously not clean or safe. The toxic waste from the landfill oozing into your basement seemed like an invasion by something alien and evil.


But then the issues became more subtle and complicated. We always had forest fires and hurricanes but somehow climate change made them worse. Viruses were always with us, but as in the case of COVID-19, they cannot be seen or smelled. These forms of damage require the interpretation of environmental and medical experts. We have to trust them to be honest and correct. Some people refuse to make that leap of faith, but most people know what they don't know and are willing to trust experts. We put our lives in the hands of medical doctors not because we like it, but because we come to realize we have no choice. We live in a complicated, high-tech world, and we rely on experts to make it work.

We think about the issues that experts call to our attention- from COVID-19 to climate change and it challenges us to identify behaviors we could modify to address them. Some of these behaviors are under our control: social distancing, wearing masks, installing solar panels or LED lights, and support for public policies that enable us to collectively address these issues. Some are behaviors not under our control, like finding yourself standing next to a person who refuses to wear a mask and is an asymptomatic carrier of COVID-19. People's values favor the freedom to move about freely in society and go mask-less whenever they want, but their values also cause them to want to protect their loved ones from harm.

Similarly, more and more people are thinking about their carbon footprint, but think about it when they turn on their air conditioner or are driving their car to work. Their values could and sometimes do, result in changed behaviors. They may look for a mass transit method of commuting, find a place to live that is closer to work, work more often from home, and purchase a more energy efficient auto and air conditioner. These values are based on a shared perception of how the world works and our current environmental conditions. It does not lead to a uniform response, but it does represent a cultural shift from the way we lived half a century ago, at the dawn of the environmental era. Fifty years ago, no one even knew they had a carbon footprint.

The culture and values of sustainability cut across ideological lines in America, but unfortunately, many of our environmental policy proposals are not designed to take advantage of that common understanding. The environmental policy of the 1970s and 1980s was largely command-and-control regulation: a necessity in a time that required new rules of the road. But despite recent attacks by the Trump Administration, those rules are hard-wired into America's legal system. They may be weakened but no Congress will legislate their end. In fact, the administration sought to weaken regulations because they knew Congress would never weaken our environmental laws. But perhaps the command-and-control model is not appropriate for decarbonization. In my view, our approach to climate change policy adheres to that same model and does not build on our shared understanding of environmental conditions. Instead, it focuses on punishing those who use fossil fuels by charging them more to use them. A more practical approach would seek to transform the fossil fuel and electric utility industry into a renewable energy business. It would use public resources to ease the impact of that transition on fossil fuel workers and owners and make decarbonization a national project built on the shared value of building a modern, sustainable energy system.

Climate change and our pattern of land use development have exacerbated the impact of extreme weather on our energy system. People now routinely experience blackouts. Generator sales have increased dramatically. A decentralized, smart-grid system based on renewable energy has a lot of appeal when compared to getting by without electricity for a few weeks. A broad consensus could be built: homeowners get reliability, environmentalists get decarbonization, workers get jobs and owners are able to be compensated for their now less valuable fuels and infrastructure.

The ideological environment in politics today favors those at the extremes. Power is achieved and maintained by defining those you disagree with as enemies and as bad people. We feel this polarization and see it every day, and yet I believe that this presidential campaign has demonstrated the desire for a return to normal political discourse characterized by mutual respect and compromise. The need for environmental sustainability and global efforts to mitigate climate change is obvious to about 70% of all Americans. We disagree on policy methods but not policy objectives. We need to avoid spiking the ball in the endzone and start talking to each other about our shared values and develop environmental policies that reflect those values. The funding model of many interest groups is based on scaring people into believing that the enemy is at the city gates: "Only giving us access to your credit card can avert disaster." The danger is reinforced by social media and has resulted in the dysfunctional policy paralysis we now live within. The only way out is by learning to listen to each other and forging compromises. The alternative is too dire to contemplate.

In 1805, Thomas Young took the mechanical equilibrium at the solid/liquid/gas three-phase contact line into consideration (the balance of forces acting on the contact line formed by the intersection of the liquid-gas interface and the solid surface), and introduced the macroscopic concept of "contact angle" and Young's equation. Based on the assumptions of isotropic, homogeneous, and smooth surface, Young's equation gives the relationship between the intrinsic contact angle of the solid surface and the interfacial free energy at the solid/liquid/gas three-phase contact line.

However, it is difficult to obtain such a perfect surface in reality, and surfaces are usually heterogeneous. Although the macroscopic surface is smooth, the microscopic surface tends to be chaotic. The contact angle obtained in this way cannot be called the intrinsic contact angle.

To explore the intrinsic wettability of materials, the team of Prof. Xiaolin Wang from the Institute for Superconducting and Electronic Materials, Australian Institute for Innovative Materials, University of Wollongong and Prof. Lei Jiang and Prof. Tian Ye from the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences jointly studied the wettability behavior of different crystal faces of sapphire (α-Al2O3) single crystals. Related results were published in the National Science Review (NSR) with the title "Crystal Face Dependent Intrinsic Wettability of Metal Oxide Surfaces".

¯1¯As we all know, the surface of alumina is hydrophilic, and the contact angle of the polycrystalline surface of alumina is about 10°. During the experiment, researchers were surprised to find that the intrinsic contact angles of all four α-Al2O3 single crystals with different crystal faces are far greater than 10°, and the contact angle of the (1-102) crystal face is very close to 90°. The previous study in our group had proven that the intrinsic hydrophilic and hydrophobic boundary of the surface material is about 65°, so the (1-102) crystal surface is hydrophobic.

Through DFT simulation of the structures of the adsorbed interfacial water molecules at different crystal faces, it was found that compared with hydrophilic (11-20), (10-10) and (0001) crystal faces, the adsorbed water molecules at (1-102) crystal face is in a standing state; that is, the hydrogen atoms of the hydrophobic crystal face are at the highest point of the first layer of adsorbed water. Therefore, water molecules from water droplets at the three-phase contact line can only form one hydrogen bond with one hydrogen atom. Since one hydrogen bond interaction is relatively weak and then the three-phase contact line is easily anchored. But on the hydrophilic crystal faces, the oxygen atoms of the adsorbed interfacial water molecule are at the highest point. In this case, there are two lone pairs of electrons of one oxygen atom to form two hydrogen bond interactions with water molecules of water droplets at the three-phase contact line. Hence, the three-line contact line is easier to spread.

So far, this work started from the atomic-level flat alumina crystal interface and proved that the orientation of adsorbed interfacial water molecules has a huge impact on macroscopic wettability of solid surfaces with the similar chemical composition (aluminum and oxygen) and almost no topographic structure (atomically flat). This work focuses on the study of intrinsic wettability of the solid interface, which may provide inspirations to improve the catalytic efficiency, prepare excellent functional materials, and improve the performance of composite devices.

Scientists show more proof Far-UVC light will kill coronavirus without hurting humans

by Chris Melore

HIGASHIHIROSHIMA, Japan — Ultraviolet light continues to be an effective weapon against the coronavirus pandemic. The problem is standard UV light can damage human cells, making it hard to clean rooms with people in them. Luckily, a study from Japan is adding further evidence that less potent forms of UV rays can do the job. Researchers say their experiments prove Far-UVC light will destroy COVID-19 without harming anyone exposed to it.

A team at Hiroshima University finds Ultraviolet C light with a wavelength of 222 nanometers offers a safer but still effective way to kill SARS-CoV-2, the virus causing COVID-19. A nanometer equals a billionth of a meter.

Regular UV light is widely used to eliminate germs on surfaces, but has a wavelength of 254 nanometers. Study authors say this kind of intense UV exposure can actually penetrate the human body.

“It is well known that 254-nm UVC is harmful to the skin and eyes. Previous reports demonstrated that 222-nm UVC light, belonging to far-UVC (207-222 nm), has the same highly effective germicidal properties as 254-nm UVC; however, it is less harmful to the skin and eyes,” researchers write in the American Journal of Infection Control.

The study adds that 254-nm light can break through the outer layer of dead cells on the skin and eyes, irradiating human tissue. Far-UVC light cannot penetrate human skin or eyes.

How well can Far-UVC light stop COVID-19?

The Japanese team uses Ushio’s Care222 krypton-chloride excimer lamp against viral cultures of SARS-CoV-2 in an in vitro experiment. After just 30 seconds of exposure, researchers find 222-nm light kills 99.7 percent of the virus. The team says this offers hospitals safer ways to sterilize work areas while keeping staff and patients out of danger.

In June, a Columbia University study also showed evidence Far-UVC light works against several strains of coronavirus and other pathogens. That report reveals UV lamps set between 207 and 222 nanometers can kill 90 percent of airborne virus particles in just eight minutes.

Both studies see the possibility for governments to start hanging “overhead far-UVC lamps” in public spaces. This technology may help lower the spread of seasonal illnesses like the flu, as Hiroshima University adds Far-UVC can also destroy the H1N1 influenza virus.


The Japanese study cautions that while there is now proof Far-UVC light can destroy COVID-19, they still need to test these rays against real-world surfaces outside of the lab.



Scientists call for serious study of 'unidentified aerial phenomena'

You don't have to be an alien truther to be curious about recent UAP events



By Leonard David

The U.S. Navy recently admitted that, indeed, strangely behaving objects caught on video by jet pilots over the years are genuine head-scratchers. There are eyewitness accounts not only from pilots but from radar operators and technicians, too.

In August, the Navy established an Unidentified Aerial Phenomena (UAP) Task Force to investigate the nature and origin of these odd sightings and determine if they could potentially pose a threat to U.S. national security.


The recently observed UAPs purportedly have accelerations that range from almost 100 Gs to thousands of Gs — far higher than a human pilot could survive. There's no air disturbance visible. They don't produce sonic booms. These and other oddities have captured the attention of "I told you so, they're here" UFO believers.

But there's also a rising call for this phenomenon to be studied scientifically — even using satellites to be on the lookout for possible future UAP events.

Wanted: high-quality evidence

Philippe Ailleris is a project controller at the European Space Agency's Space Research and Technology Center in the Netherlands. He's also the primary force behind the Unidentified Aerospace Phenomena Observations Reporting Scheme, a project to facilitate the collection of UAP reports from both amateur and professional astronomers.


There's a need for the scientific study of UAPs and a requirement to assemble reliable evidence, something that could not be so easily ignored by science, Ailleris told Space.com.

It is necessary to bring scientists objective and high-quality data, Ailleris said. "No one knows where and when a UAP can potentially appear, hence the difficulty of scientific research in this domain."

New tools

Recent years have seen rapid advances in information and communication technologies — for example, open tools and software, cloud computing and artificial intelligence with machine and deep learning, Ailleris said. These tools offer scientists new possibilities to collect, store, manipulate and transmit data.


Ailleris points to another potent tool. "The location over our heads of satellites is the perfect chance to potentially detect something," he said.


Working in the space sector, it occurred to Ailleris that Earth-observation civilian satellites could be used to search for UAPs. One avenue is tapping into free-of-charge imagery collected by the European Union's Copernicus satellites, an Earth-observing program coordinated and managed by the European Commission in partnership with ESA.


Also, there are more and more Earth-scanning spacecraft being launched to take the pulse of our globe. Such work is no longer limited to major countries or powers, Ailleris said; private actors have also entered the planet-viewing scene.

"This evolution will stimulate forward-thinking ideas across different domains, including controversial topics," Ailleris said. "And why not the UAP research field?"

UAP expedition

Working with Ailleris to employ satellite imagery to detect and monitor UAPs is Kevin Knuth, a former scientist with NASA's Ames Research Center in California's Silicon Valley. He is now an associate professor of physics at the University at Albany in New York.

"We are looking into using satellites to monitor the region of ocean south of Catalina Island where the 2004 Nimitz encounters occurred," Knuth said, referring to UAP sightings reported by pilots and radar operators based aboard the aircraft carrier USS Nimitz.

That area will also be the target for a 2021 UAP expedition carried out by Knuth and other researchers. The goal of the outing is "to provide unassailable scientific evidence that UAP objects are real, UAP objects are findable and UAP objects are knowable," according to the website for the project, which is called UAPx.


The UAPx team includes military veterans and physicists, as well as research scientists and trained observers that will use specialized gear to observe any would-be UAP.


"We are hoping to detect UAPs, determine their characteristics, flight patterns and any patterns in activity that will allow us to study them more effectively," Knuth told Space.com. "In addition to monitoring a region for UAPs, we are also looking into using satellites to obtain independent confirmation of prominent UAP sightings and to obtain quantifiable information about those UAPs."

Science problem

"I certainly think that UAP deserve to be studied, just like we would do with any other problem in science," said Jacob Haqq-Misra, an astrobiologist with the Blue Marble Space Institute of Science in Seattle, Washington.

In August, Haqq-Misra helped organize a NASA-sponsored interdisciplinary workshop, called TechnoClimes 2020, that sought to prioritize and guide future theoretical and observational studies of non-radio "technosignatures" — that is, observational manifestations of technology, particularly those that could be detected through astronomical or other means.

Haqq-Misra said his knowledge regarding UAPs stems from the public domain, such as the recently released Navy videos and Department of Defense comments. But otherwise, he has not conducted any of his own investigations into the problem.

"I also remain agnostic as to any particular hypothesis that might explain UAP, at least until we have more data to consider," Haqq-Misra said. "The non-human intelligence hypothesis is a popular one, but I don't necessarily have any indication that it is more probable than any other hypothesis at this point."

'Outlaws' of physics

Ravi Kopparapu is a planetary scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland who studies planetary habitability, climate modeling and chemistry in the context of exoplanet atmosphere characterization. He views the UAP/UFO phenomena as a scientifically interesting problem, driven in part by observations that seem to defy the laws of physics.

That said, Kopparapu said he's wary of bringing the term "extraterrestrial" into the conversation. "That's because there is absolutely no concrete evidence that I know of that points to them as being extraterrestrial," he said. 

"There's a fundamental problem that we have right now to scientifically study UAP," Kopparapu said. "We do not have proper data collection of this phenomena that can be shared among interested scientists to verify claims and filter out truly unexplainable events."

Also, the entire UAP topic has been much maligned by being associated with ET, Kopparapu added. This association prevents a thorough scientific investigation by the science community, he feels, essentially because of a taboo surrounding ET claims.

"I think people immediately think about 'aliens' when they hear UFOs/UAPs, and I want scientists to not fall for that," Kopparapu said. "Be strictly agnostic and don't let preconceived ideas cloud judgments. Have an open mind. Consider this as a science problem. If it turns out these have mundane explanations, so be it."

Kopparapu and like-minded colleagues are proposing a completely unbiased, agnostic approach to study UAP, he said: "Let the data lead us to what they are."

Drought once shut down Old Faithful—and might again

Petrified wood suggests Old Faithful's regular eruptions went quiet 800 years ago.


YINYANG/ISTOCK.COM By Colin Barras Oct. 12, 2020 , 9:55 AM

Old Faithful, it turns out, wasn’t always so faithful. The geyser, in Wyoming’s Yellowstone National Park, is famous because it blasts hot water tens of meters into the air at regular intervals—every 90 to 94 minutes, on average. Now, geologists examining petrified wood from the park have found evidence that 800 years ago, Old Faithful stopped erupting entirely for several decades, in response to a severe drought. With climate change making drought more common across the western United States, the researchers say a similar shutdown might happen again.

The world’s 1000 or so geysers typically occur in areas that are volcanically active, like Yellowstone. Water percolating down through the ground reaches the boiling point as it approaches the heat of a magma chamber. But because the water is deep underground it is also at a high pressure that prevents it from becoming steam. Eventually, the superheated water becomes hot enough to vaporize, triggering an explosive eruption of water and steam at the geyser’s vent.

Many geysers erupt randomly, but when Henry Washburn and his fellow explorers traveled through Yellowstone in 1870, they noted the regularity of Old Faithful and named it to reflect its predictability.

Shaul Hurwitz, a geologist at the U.S. Geological Survey, and his colleagues wondered whether it was always so dependable. Today, the area around the geyser is barren because vegetation can’t survive the blasts of hot, alkaline water. Back in the 1950s, however, a researcher found chunks of ancient wood near the geyser, mineralized and preserved by Old Faithful’s silica-rich waters. The wood suggested there was a time when trees could grow because there were no eruptions. To investigate, Hurwitz and his colleagues persuaded the National Park Service to let them date 13 such specimens.

“When I submitted the samples for radiocarbon dating I didn’t know whether they would be hundreds or thousands of years old,” Hurwitz says. “It was an ‘aha!’ moment when they all clustered within a hundred-year period in the 13th and 14th centuries.”

Three of the wood fragments were lodgepole pines, still common in Yellowstone today, the team reported on 7 October in Geophysical Research Letters. One specimen—a 2.4-meter-long section of trunk—came from a tree the researchers estimate grew for 80 years, which suggests Old Faithful failed to erupt for almost a century.

The researchers turned to the scientific literature in search of an explanation for the eruption hiatus. They found that all their samples fell at the end of the Medieval Climate Anomaly, a warm and dry period felt across the Northern Hemisphere thought to have been caused, in part, by changes in ocean circulation. It began in 950 C.E. and in the western U.S. was still causing droughts in the late 1200s. The researchers argue a lengthy drought would have starved Old Faithful of the water it needs to erupt, paradoxically allowing some drought-tolerant trees to grow.

Jamie Farrell, a geophysicist at the University of Utah who studies Yellowstone and who wasn’t involved in the study, says the analysis makes sense. “If you have prolonged drought and there isn’t enough water to feed these systems, then features like Old Faithful might sometimes stop erupting,” he says.

Broxton Bird, a geologist at Indiana University–Purdue University, Indianapolis, who specializes in climate change, agrees. He says the Medieval Climate Anomaly was severe enough to make it happen. “Water tables would be getting lower and lower, and right at the end of that Old Faithful shuts down,” he says. The droughts would have made farming in the western U.S. difficult, he adds. This may help explain why the Pueblo dwellings of ancestral Native Americans in the southwest U.S. were abandoned at the time.

Hurwitz and his colleagues say that with climate change making megadroughts more likely across the western U.S., Old Faithful might erupt less frequently in the future–and might even stop altogether.

Maxwell Rudolph, a geophysicist at the University of California, Davis, says that would be tragic for the millions of people who visit Old Faithful. “The extinction of this natural treasure would be a profound loss.”
World Bank Falling $81 Billion Short on COVID Funding Promises

WASHINGTON, DC—At its current pace, the World Bank could fall $81 billion short on its $160 billion target for emergency funding to help developing countries deal with the effects of COVID-19, according to a new study from the Center for Global Development (CGD).

The researchers built a database of the more than 500,000 World Bank transactions since before 2008 to track the Bank’s performance during the current crisis against the norm. They found that the World Bank is lagging both on its rate of new commitments and on the speed it is disbursing loans compared to the bank’s performance during the global financial crisis a decade ago.

The study found:


At its current rate, the Bank’s new commitments will fall $31 billion short of its target of $160 billion by June 2021.


More importantly, they found, the slow rate of disbursements falls far short of that headline target. At the current pace, just $79 billion of the $160 billion target will flow to developing countries by June 2021.


The expected shortfall against the Bank’s lending target



“The World Bank’s own analysis suggests we’re in the midst of a tragic reversal of years of progress in reducing global poverty. So far, the Bank has responded with modest half measures, fretted over its own triple-A credit rating, and talked about conditioning further assistance on structural reforms. The bankers need to get a lot more creative in moving money,” said Justin Sandefur, a senior fellow at CGD and an author of the study.

The researchers also found:


The World Bank has not shifted to providing more direct budgetary support, as it had during the 2008 crisis, which may partially explain the slow rate of disbursement.


Low-income countries have mostly received money faster than middle-income countries, and World Bank financing has met a somewhat larger percentage of financing needs for poorer countries.


Countries like El Salvador, Indonesia, and Yemen are currently paying more to the World Bank to service old debts than they are receiving from the institution in crisis support.

“It’s particularly troubling that World Bank is currently a drag on the ability of some countries to respond this crisis. At a minimum, countries should not be paying more to the bank to service old debts than they are receiving in crisis support,” said Scott Morris, the co-director of CGD’s development finance program and an author of the study.

China is sending more of its Gaofen satellites into space. Here’s why


The launch of Gaofen-13 continues a project that so far comprises more than 20 satellites, with a busy schedule of missions coming next

Part of a determined push into space by China, the satellites have multiple purposes, from mineral detection to 
defense

China has sent its Gaofen-13 satellite into orbit, kicking off a spree of space missions that will bring a dozen major launches in the next few months.

The Gaofen-13 was launched early on Monday morning with a Long March-3B (CZ-3B) rocket from Xichang Satellite Launch Centre in Sichuan province, in the country’s southwest.


It is a high-orbit remote sensing satellite, one of the Gaofen series, that will take high-definition optical images of the Earth.

What are Gaofen satellites?


“Gaofen” is a Chinese abbreviation of “high resolution”, which refers to the High Resolution Earth Observation Satellite programme.

China began the project in 2010 and has launched more than 20 satellites, over half of them in the past two years.

These satellites observe and take photos of the Earth, including some infrared ray images, which can be used for many civilian purposes, including monitoring pollution and environment, estimating agricultural yields, forecasting weather and disasters, and detecting minerals.

Do Chinese satellites have military uses?


There are also military applications for the satellites. Last month, China released a video captured by the Jilin-1 Gaofen-3 satellite, in which it continuously tracked the flight of a fighter jet, thought to be an F-22, the most advanced American stealth fighter.

Stealth jets are designed to avoid radar detection, but are visible by optical observation. If equipped with higher-resolution cameras and advanced identification and tracking capabilities thanks to artificial intelligence, these satellites could serve as an important support to air defence radars.

What are China’s next space plans?


By the end of March, China’s satellite launch sites will have a mission almost every other week, with the shortest gap being only five days, according to Zhang Xueyu, the director of the Xichang launch centre.

“This frequency is unprecedented and the operation will be constantly saturated, close to the limit of our capacity,” Zhang told government newspaper Science and Technology Daily.

The most notable launch will be that of the Chang’e-5 lunar exploration mission, which is scheduled for late November. It is expected to land on the moon and then return to Earth with at least 2kg (4.4 pounds) of lunar rock samples.

China launches mission to Mars with lift-off of home-grown Tianwen-1 spacecraft

China has ambitious space plans and has carried out a number of significant missions. This year alone, it has sent its first independent Mars probe, Tianwen-1, on the way to the red planet, completed the 30-satellite constellation for its
BeiDou navigation system – its rival to the United States’ Global Positioning System (GPS) – and tested a new type of manned spaceship and its new heavy-lift rocket Long March-5B.

Next year, the core module of a permanent Chinese space station is also on the agenda.

Why is China stepping up its space programmes?

China considers space of great importance to both national security and technological development.

Meanwhile, it is banned by Washington from taking part in US-led space programmes. This forced Beijing to be self-sufficient, such as by building a space station of its own, and developing BeiDou.

While the relationship with the US has deteriorated in the past couple of years and been described by some as a new cold war, competition in space has intensified, including in efforts to carry out the next manned mission to the moon.

The establishment of the US Space Force last December was a symbolic event. China, too, stepped up its space programmes, and this summer brought a head-on race to Mars, with China’s Tianwen-1 and Nasa’s Perseverance launched one week apart.

Unknown to humanity, in the later decades of the last century an environmental crisis was slowly unfolding in the upper atmosphere. The existence of the ozone layer was proved by chemists in the early 20th century, but as a scientific curiosity rather than a cause for concern. A thin layer between the troposphere, in which we live, and the stratosphere, the ozone layer filters out about 99% of harmful ultraviolet light from the sun before it hits the Earth. Exposure to unfiltered ultraviolet light can cause skin cancers, eye damage and weakened immune systems.

What we did not know until the mid 1970s was that chlorofluorocarbons (CFCs), chemicals that had come into widespread use as refrigerant gases and aerosol propellants, were reacting unseen with the ozone layer, fatally thinning the Earth’s protective cloak.



Mario Molina, who has died of a heart attack aged 77, won the Nobel prize for chemistry in 1995, along with F Sherwood Rowland and the Dutch scientist Paul Crutzen, for their work unravelling the impact of CFCs on the ozone layer, and the stark warning they delivered to humanity. Molina and Rowland jointly published a landmark paper in the peer-review journal Nature in 1974 showing the impact of CFCs on ozone.

Despite the strength of their science, it was more than a decade before their work was acted upon, amid protestations from the chemical industry. Nasa at first reported that their data showed no signs of ozone depletion – it was later discovered they were led astray by computer software trained to ignore what seemed anomalous readings. It was only with the work of Joe Farman and colleagues at the British Antarctic Survey in another Nature paper in 1985 that clinching proof was obtained – a vast hole was opening up in the ozone layer over the South Pole.




The discovery was made just in time: at the rate of destruction in the mid-80s, the ozone layer could have been damaged beyond repair in as little as a decade.

Molina was a young chemist, who had barely finished his PhD, when he started working with Rowland on the study of CFCs that would transform his career and avert disaster. Born in Mexico City to Roberto Molina Pasquel, a lawyer and judge who later served as ambassador to Ethiopia, Australia and the Philippines, and Leonor Henriquez, he showed his fascination for the world of science early on. Perhaps influenced by his aunt Esther, a chemist, as a child he set up a mini laboratory in a bathroom at home with toy microscopes and chemistry sets.

He went to boarding school in Switzerland at the age of 11, believing that to speak German was essential for a serious chemist, before returning to high school in Mexico. As he later recalled: “I was disappointed that my European schoolmates had no more interest in science than my Mexican friends. I had already decided to become a research chemist; earlier, I had seriously contemplated the possibility of pursuing a career in music – I used to play the violin in those days.”

After graduating in chemical engineering from the National Autonomous University of Mexico (UNAM) in 1965, Molina went on to study at the University of Freiburg in Germany, and then to a PhD in laser chemistry in 1972 from Berkeley, part of the University of California. He then joined, as a post-doctoral research associate, a group led by Rowland, professor of chemistry at the University of California, Irvine.

In 1972 Rowland had attended a presentation on the work of James Lovelock, a British scientist who had measured traces of CFCs – then thought to be harmless – with instruments he had designed. Rowland realised that CFCs were not likely to be as inert as was thought when found at altitude, and offered this to Molina as a choice among several subjects for research.

“Mario chose the one furthest from his previous experience and from my own experience as well, and we began studying the atmospheric fate of the CFC molecules,” Rowland recounted. “Within three months, Mario and I realised that this was not just a scientific question, challenging and interesting to us, but a potentially grave environmental problem involving substantial depletion of the stratospheric ozone layer. A major part of both of our careers since has been spent on the continuing threads of this original problem.”

While at Berkeley Molina also met Luisa Y Tan, a fellow chemist, who went on to be president of the Molina Center for Strategic Studies in Energy and the Environment at La Jolla, California. They married in 1973 and their son Felipe was born in 1977. The marriage ended in divorce and Molina was married again, to Guadalupe Álvarez, in 2006.

Though he spent much of his working life in the US, including stints as a scientific adviser to President Barack Obama and at the Massachusetts Institute of Technology, Molina continued to act as a figurehead for Mexican science throughout his life, holding a professorship at UNAM. In 2015 UNAM inaugurated the Mario Molina building, a collaboration between industry and research scientists. When his country played host to climate talks in 2010, Molina played a significant role. In his later years the climate emergency became an increasing area of focus, along with air quality and air pollution.

The ozone layer is now recovering, and should be close to full repair by the 2080s, thanks to an international treaty – the Montreal protocol, signed in 1987 – that phased out CFCs. What is less known is that Molina’s work will also help to avert ruin from that other dire emergency, the climate crisis. Some of the substitutes for CFCs held an unrecognised danger: they are powerful greenhouse gases, with the potential to warm the planet at a rate many thousands of times greater than carbon dioxide. Last year the Kigali amendment to the Montreal protocol came into force, phasing out a raft of these chemicals too.

Durwood Zaelke, president of the US-based Institute for Governance and Sustainable Development, who worked with Molina on urging governments to take action on the climate, said: “The Montreal protocol solved the first great threat to the global atmosphere, and has done more to solve the next threat – the climate threat – than any other agreement, including the Paris agreement. Phasing down CFCs and related fluorinated gases has avoided more climate warming than carbon dioxide is causing today. Mario remained deeply involved until his last days.”

He is survived by his wife, his son, three stepchildren, two brothers and a sister and two grandchildren.

Famous feather definitely belonged to this terrifying Jurassic-era dinosaur

Research compared feather, discovered in 1861, with fossilized remains of other archaeopteryx feathers

The first-ever dinosaur feather discovered does indeed belong to the archaeopteryx, according to a new study, putting an end to a controversy that has waged within the scientific community for more than 100 years.

The research compared the feather, discovered in 1861, with the fossilized remains of other archaeopteryx feathers. The experts determined its owner is no longer a mystery and it definitely belonged to archaeopteryx.

“There’s been debate for the past 159 years as to whether or not this feather belongs to the same species as the Archaeopteryx skeletons, as well as where on the body it came from and its original color,” said the study's lead author, Ryan Carney, assistant professor of integrative biology at the University of South Florida, in a statement. “Through scientific detective work that combined new techniques with old fossils and literature, we were able to finally solve these centuries-old mysteries.”

In 2019, the debate over what creature the feather belonged to was given new life after a study said it did not belong to archaeopteryx. Those researchers suggested it may have stemmed from a different feathered dinosaur that lived in the Solnhofen Archipelago in what is now Germany.

Fox News has reached out to the authors of the 2019 study with a request for comment.

Archaeopteryx was a transitional dinosaur that lived 125 million years ago and bridged the gap between non-avian feathered dinosaurs and modern-day birds.

Carney and the other researchers used a high-powered electron microscope to gather images of the feather, which they determined came from the bird's left wing.

"They also detected melanosomes, which are microscopic pigment structures," the statement added. "After refining their color reconstruction, they found that the feather was entirely matte black, not black and white as another study has claimed."

The study was published in Scientific Reports.

In March 2018, researchers suggested that archaeopteryx could probably fly but in a different manner from modern-day birds, in rapid, short bursts over small distances.

Archaeopteryx possessed feathers, like a modern-day bird. However, it also possessed a "long, stiff, frond-feathered tail" and teeth, along with bones in its hands, shoulders and pelvis that were not fused.

Some 12 fossils of archaeopteryx have been found, the first discovered in the late 19th century by famed German paleontologist Hermann von Meyer. The most recent was discovered by an amateur collector in 2010, announced in February 2014 and described scientifically in 2018.
