  • Extreme Heat Causes Hottest July on Record

    July 2021 was the hottest July ever recorded worldwide, the US government has reported. This information was compiled and released in August by the National Oceanic and Atmospheric Administration (NOAA) of the US Department of Commerce. “July is typically the world’s warmest month of the year, but July 2021 outdid itself as the hottest July and month ever recorded,” said NOAA Administrator Dr. Rick Spinrad. “This new record adds to the disturbing and disruptive path that climate change has set for the globe.” According to NOAA data, temperatures were already warming ahead of this year’s July record. July’s temperatures were 0.02°F (0.01°C) higher than the previous record set in July 2016, which was later tied in 2019 and again in 2020. The recorded monthly temperatures go back 142 years. Breaking the data down further, the Northern Hemisphere’s land-surface-only temperatures broke July’s record by an “unprecedented” 2.77°F, while Asia had its hottest July and Europe recorded its second-hottest July on record. While no one knows what the rest of this year will bring, estimates suggest that 2021, at the very least, should come in as one of the ten warmest years ever. According to Spinrad, “a sobering IPCC report finds that human influence is, unequivocally, causing climate change, and it confirms the impacts are widespread and rapidly intensifying.” Read more on this story from NOAA.

  • Extracting Rare Earth Metals from Coal Waste

    Rare earth elements (REE), often referred to as “rare earth metals,” are crucial for their use, along with their oxides, in various modern devices. These include the use of REEs for batteries in computers, cell phones, and electric vehicles, and the use of rare-earth oxides for digital displays, monitors, and televisions. REEs are also used as catalysts, phosphors, and polishing compounds. In response to increasing demands for REEs, the US is seeking alternative production of REEs. The Bipartisan Infrastructure Law, passed on November 15, 2021, gave the US Department of Energy (DOE) $140 million for fiscal year 2022 to establish a rare earth elements demonstration facility. The purpose of the facility is as follows, with extraction from coal waste: “(A) provide environmental benefits through use of feedstock derived from acid mine drainage, mine waste, or other deleterious material; (B) separate mixed rare earth oxides into pure oxides of each rare earth element; (C) refine rare earth oxides into rare earth metals; and (D) provide for separation of rare earth oxides and refining into rare earth metals at a single site.” On February 9, 2022, a study conducted by James Tour and his team from Rice University in Houston, Texas, which included DOE funding, was published in Science Advances. Tour’s team reported the use of superfast flash Joule heating (FJH) on coal waste to improve REE extractability. The DOE then released a Request for Information (RFI) on February 14, 2022 to solicit feedback from relevant stakeholders regarding the proposed rare earth elements demonstration facility, including demonstration facility features, supply chain considerations, research and development needs, and more. Improvements are still needed in the extraction of REEs from coal waste. However, there is promise in new technologies, such as in the study above, to make the extraction of REEs more practical, especially given the amount of coal waste that already exists.

  • Buzz on: Consuming Coffee May Lengthen Life

    Study Cites Beneficial Coffee Components Coffee drinkers, rejoice. Moderate consumption—two or three cups of coffee a day—is associated with increased longevity and lower risk of cardiovascular disease when compared with abstinence from coffee drinking. These are some of the findings of a recently published study by Kistler et al. in the European Journal of Preventive Cardiology. The study’s findings apply to the most common types of coffee consumed today. “In this large, observational study, ground, instant and decaffeinated coffee were associated with equivalent reductions in the incidence of cardiovascular disease and death from cardiovascular disease or any cause," said study author Professor Peter Kistler of the Baker Heart and Diabetes Research Institute, Melbourne, Australia, according to a Science Daily news brief. "The results suggest that mild to moderate intake of ground, instant and decaffeinated coffee should be considered part of a healthy lifestyle," Kistler added. Using data from UK Biobank, the researchers examined links between types of coffee and arrhythmias, cardiovascular disease, and death for people between 40 and 69 years of age. The median age of participants was 58 years and 55.3% were women. Cardiovascular disease consisted of coronary heart disease, congestive heart failure, and ischemic stroke. Coffee drinkers were compared to non-drinkers after adjusting for “age, sex, ethnicity, obesity, high blood pressure, diabetes, obstructive sleep apnea, smoking status, and tea and alcohol consumption,” according to the Science Daily report. Reduction in death from any cause was associated with all types of coffee consumed. Drinking between two and three cups per day showed the greatest reduction. Compared to non-drinking of coffee, it was linked to a “14%, 27% and 11% lower likelihood of death for decaffeinated, ground, and instant preparations, respectively,” said Science Daily. When it comes to promoting health, coffee has a lot going for it, according to Prof. Kistler, as quoted in the Science Daily report. “Caffeine is the most well-known constituent in coffee, but the beverage contains more than 100 biologically active components. It is likely that the non-caffeinated compounds were responsible for the positive relationships observed between coffee drinking, cardiovascular disease and survival. Our findings indicate that drinking modest amounts of coffee of all types should not be discouraged but can be enjoyed as a heart healthy behavior.” Sources: https://www.sciencedaily.com/releases/2022/09/220926200838.htm https://academic.oup.com/eurjpc/advance-article/doi/10.1093/eurjpc/zwac189/6704995

  • Global Electricity Use Soared Last Year

    Global electricity use surged 6% in 2021, the largest increase in more than a decade, the International Energy Agency (IEA) says in a recent report. Renewable power has been growing substantially, but 2021 electricity generation from coal and gas hit record levels, the IEA said in its Electricity Market Report—January 2022. “As a result, the global electricity sector’s annual carbon dioxide emissions leaped to a new all-time high after having decreased for the previous two years,” the IEA said. The agency predicts that renewables will “meet the vast majority of the increase in global electricity demand,” resulting in a “plateauing of emissions from electricity generation.” However, this will not assist with immediate goals, said IEA Executive Director Fatih Birol. "Emissions from electricity need to decline by 55% by 2030 to meet our Net Zero Emissions by 2050 Scenario,” he said. Absent major policy action from governments, “emissions are set to remain around the same level for the next three years,” he added.

  • C.R.E.A.T.I.O.N: Faith and the Environment

    “I used to think the top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that with 30 years of good science we could address those problems. But I was wrong. The top environmental problems are selfishness, greed and apathy … and to deal with those we need a spiritual and cultural transformation — and we scientists don’t know how to do that.” – Gus Speth, former United Nations Development Programme (UNEP) Administrator, 2014. Already globally recognized each year as Earth Day, April 22 was officially declared by the UN as International Mother Earth Day in 2009. This day is one of many days and initiatives, such as World Wetlands Day (February 2), that the UN has established to address environmental issues. One such environmental project, not widely covered by the mainstream media, is the UN’s Faith for Earth Initiative, a global coalition of interfaith actors that work together to focus faith resources on the environment. Referring to the UN’s resolve in 2008 to focus more attention on “interreligious and intercultural dialogue,” the UN Environment Programme (UNEP) declares on its Faith for Earth Initiative website that “spiritual values for more than 80% of the people living on earth have been driving individual behaviors.” It follows that spiritual values drive behaviors toward the environment, as well, and thus the Faith for Earth Initiative was born in November 2017. The initiative’s mission is “to encourage, empower and engage with faith-based organizations as partners, at all levels, toward achieving the Sustainable Development Goals and fulfilling the 2030 Agenda.” Its vision, “a world where everything is in balance,” is based on eight “shared values” that spell CREATION: C: Communication — Effective communication at all levels between all stakeholders. R: Respect — All spiritual and religious beliefs are respected. E: Empower — Empower and engage all stakeholders. A: Act — Act in coherence with individual reflection and communal beliefs. T: Transform — Transform people’s behavior for a more responsible lifestyle inspired by their own faiths. I: Inspire — Inspire innovative approaches to achieve the 2030 Agenda. O: Organize — Organize knowledge and other resources related to faiths and sustainable development. N: Network — Build a strong network between the UN and faith-based organizations. According to the UNEP, the initiative’s success will require trust-building between what the UNEP calls “the perceived secular values of the UN” and the values of the faith actors. Part of its strategy will be to engage local communities of faith, as well as establish a top-level “Coalition for Creation” to influence environmental policy.

  • Global Green Jobs for Youth Outlook

    The COVID-19 pandemic hit global economies hard. Still, the global market for green jobs looks promising, especially for young people. Over 200 million students are currently enrolled in higher education worldwide. About 71 million unemployed youth are looking for a job today. The transition to a green economy will add about 60 million new jobs worldwide to the market by 2030. Green jobs have been defined as jobs that contribute to, preserve, or restore the environment, regardless of sector. The renewable energy sector employed 11.5 million people in 2019. With increased investment, jobs in renewables could reach 42 million by 2050. That does not include another 21.3 million jobs in energy efficiency and 14.5 million jobs related to power grids. Women currently represent only 32% of the renewable energy workforce, with 45% in administrative roles, 35% in non-STEM technical roles, and only 28% in STEM positions.

  • New Battery Technology for Next Generation Electric Vehicles

    *AUTHOR BIO Longer-lasting batteries to permit longer driving times with electric vehicles (EVs) are desperately needed to revolutionize transportation, Dr. Yang-Kook Sun, world-renowned expert in advanced battery technology, told the Twenty-Seventh International Conference on the Unity of the Sciences, held virtually April 23–24, 2021. Noting that cutting greenhouse gas emissions is essential to halt rising global temperatures, which have already increased by 1.29°C since 1880, Dr. Sun outlined the current dilemma and then highlighted the immediate need for improved electric vehicle technology. EVs today, such as the Tesla Model 3 and Hyundai Kona, typically have a driving range between 300 and 400 km (180 to 250 mi) per charge. However, the next major benchmark—driving ranges in excess of 500 km per charge—will require more advanced battery components. In his presentation, Dr. Sun said that high capacity nickel-rich cathodes—such as LiMO2 (M = Ni, Co, Mn, called NCM or A1 called NCA)—have been prime candidate materials for next generation EV batteries. Over time, researchers have been able to steadily increase the fraction of nickel (Ni) in these cathodes to increase the capacity of current. Unfortunately, as Dr. Sun explained, this approach is limited by the deterioration of capacity retention and thermal stability caused by excessive Ni enrichment. During H2-H3 phase transition (when lithium ions are extracted, or the battery is in use), the notable volume change of the cathode causes microcracks in the structure. The resulting buildup of impurities ultimately accelerates the degradation of the internal structure of the battery. Cycle ability, thermal stability, and rate capacity are all adversely affected. To overcome the tradeoff relationship between reversible capacity and cycling stability, Dr. Sun presented two approaches. One approach is to use a concentration gradient of rod-shaped particles that extends radially from the center of the cathode. This can be done in boron-doped Ni-rich cathodes (where boron is added to change the properties of the cathode). Boron plays a vital role in producing highly oriented and elongated primary particles, which can effectively dissipate the internal strain resulting from H2-H3 phase transitions, realizing a significant improvement in cycling stability. Another strategy involves optimizing the crystal structure and shape of particles by introducing ions with high valency (>5+), such as tantalum (Ta). The substituted Ta not only induces the ordered occupation of Li sites by Ni ions but also produces radially oriented primary particles, as demonstrated by Li[Ni0.9Co0.09Ta0.01]O2 with a capacity retention of 90% after 2000 cycles. Commenting on Dr. Sun’s presentation, Dr. Walter van Schalkwijk, affiliate professor of the Clean Energy Institute of the University of Washington, “Dr. Sun has shown that microstructure engineering of cathode particles using gradient composition modification and doping combined with protective coatings may provide a long-sound method of harnessing the high capacity of Ni-rich layered cathodes without sacrificing the cycling stability.” For more information on Dr. Sun’s latest research: https://hanyang.elsevierpure.com/en/persons/yang-kook-sun https://pubs.rsc.org/en/content/articlehtml/2021/ee/d0ee03774e *Dr. Yang-kook Sun is a Professor in the Department of Energy Engineering at Hanyang University in Seoul, Korea.

  • Cheetahs Return to India After 70 Years

    Namibia and India have agreed to a historic pact to relocate African cheetahs to a part of India where Asiatic cheetahs once roamed. Eight of the animals, four males and four females, are due to arrive from Namibia in August 2022 to coincide with commemorations of India’s 75th year of independence. Cheetahs have been extinct in India for over 70 years. India Minister Bhupender Yadav, who heads the Ministry of Environment, Forest and Climate Change, tweeted that “restoring the fastest terrestrial flagship species, the cheetah, in India, will rekindle the ecological dynamics of the landscape." "Cheetah reintroduction would also greatly enhance local community livelihoods through eco-tourism prospects in the long term," he added. The “Action Plan for the Introduction of Cheetah in India,” unveiled in a January 2022 press release, was co-signed with Namibia’s Deputy Prime Minister Netumbo Nandi-Ndaitwah. As part of the announcement, Minister Yadav conveyed India Prime Minister Narendra Modi’s intention to conserve seven “major big cats” in India. Minister Yadav said that “fifty cheetahs will be introduced in various national parks over five years.” The new home for the first group of cheetahs is set to be the Kuno Palpur National Park in India’s Madhya Pradesh state. All villages have already been relocated outside this park, and the location has ample prey and grasslands. The site can also sustain populations of tigers, leopards, and lions, as they naturally coexist with cheetahs. Other sites considered for relocation are: Nauradehi Wildlife Sanctuary, Madhya Pradesh Gandhi Sagar Wildlife Sanctuary, Madhya Pradesh Shahgarh bulge, Rajasthan Mukundara Tiger Reserve, Rajasthan Cheetahs fight extinction because of human-wildlife conflict, loss of habitat and prey, and poaching and illegal wildlife trafficking. In Iran, the Asiatic cheetah has almost disappeared, with about a dozen known survivors. In May, Iranian officials happily announced that three cheetah cubs were born in Touran Wildlife Refuge—the first cheetah births in captivity. However, two of the cubs died within the month.

  • Caribbean Shores Smothered by Summer Seaweed

    Seaweed washing up on Caribbean shores is nothing new, but it has been showing up in the record numbers this summer. Words like “smothering” and “choking” have been used to describe the heaping mounds of brownish seaweed covering beaches from Florida to Puerto Rico to Barbados. More than a nuisance, the invading plants have stymied tourists and local hospitality businesses as reports come in of dying fish and the smell of noxious gases. Enjoying a swim is out too, due to the long, crescent-shaped blankets of seaweed that choke fishing grounds before washing ashore. According to the University of South Florida’s Optical Oceanography Lab, a staggering 24 million tons of the brown seaweed, called sargassum, covered the Atlantic in June, breaking the 2018 record by 20%. USF offers a sargassum monitoring report called the Sargassum Watch System (SaWS) via its website, using information provided by NASA and other sources. Causes for the influx are not yet fully known, but according to the UN Environment Caribbean Programme (UNCEP), associated factors may include rising ocean temperatures, nitrogen fertilizer runoff, and sewage that feed algal growth.

  • Nuclear War Impacts Updated

    The war in Ukraine has raised fresh concerns about nuclear war. Louisiana State University (LSU) research brings us up-to-date on what would occur in hypothetical scenarios. Nuclear War in Hypothetical Scenarios According to the Stockholm International Peace Research Institute, nine nations control the world’s 13,000+ nuclear weapons. According to the LSU study, the first month following nuclear detonation would see average global temperatures plunge by about 13°F, a bigger temperature change than occurred during the last Ice Age. Rapidly dropping ocean temperatures would expand sea ice by more than 6 million square miles and 6 feet deep in places, possibly blocking major ports, such as Beijing's Port of Tianjin. Urban firestorms could send particles into the upper troposphere and lower stratosphere. The resultant smoke would last three times longer than volcanic aerosols. In a US vs Russia scenario, shortwave radiation could be reduced by 70%, and the global average surface temperature (including land) could decline by 7°C (44.6°F) at first, reaching a peak anomaly of −10°C (14°F) in the third year. Following each of the nuclear war scenarios, a decade-long solar radiation reduction and cooling event would occur. In all nuclear war scenarios, temperature modifications and biogeochemical profiles would continue for decades, more likely for hundreds of years, due to long recovery times for the deep ocean.

  • Baptismal Rite Breaks New Ground

    The Anglican (Church of England) Bishop of Oxford has added a new environmentally friendly vow to the church’s baptismal rite. According to Anglican Mainstream, the Rt. Rev. Steven Croft added a sixth question to the liturgy that calls on the newly baptized to strive to safeguard the integrity of creation and sustain and renew the life of the Earth, with the response being: With the help of God, I will. Speaking on June 11, 2022, to the church’s Diocesan Synod, the bishop read the following scripture in support of his stance: Psalms 24 The earth is the LORD’s and everything in it, The world and all those who live in it For he has founded it on the seas And established it on the rivers. The bishop recalled his father’s gardening expertise and how it helped him to understand the role of human beings in caring for the natural world: Part of our role is to tend creation; the first and recurring image of paradise in scripture is a beautiful garden. The word "paradise" itself is a Babylonian word meaning walled garden. A garden is not an entirely natural thing. It does not happen by itself. Sources: Anglican Mainstream, Diocese of Oxford

  • UNEP Celebrates 50 Years of Milestones

    The United Nations Environment Programme (UNEP) was founded fifty years ago (1972) as an outcome of the first global environmental conference, held that year in Stockholm, Sweden. To celebrate its golden anniversary, UNEP released an update on its important milestones. UNEP Milestones To date, the UNEP has 193 member states. In 1973, the MARPOL treaty was signed to address ocean pollution from ships and CITES was signed to curb or control the international trade of wild species. All in all, UNEP served as a “docking station” for 15 multilateral environmental agreements related to everything from air and water pollution to species conservation. On June 5, 1974, UNEP initiated the first World Environment Day. UNEP moved into its present home on the outskirts of Nairobi, Kenya, in 1975. The International Panel on Climate Change (IPCC), founded by UNEP and the World Meteorological Organization (WMO), won a Nobel Peace Prize in 2007. UNEP member states signed the Paris Agreement in 2015 to limit global warming to 1.5°C (equivalent to 2.7°F). The Sustainable Development Goals (SDGs) were also introduced in 2015. UNEP released its Making Peace with Nature Report in 2021. UNEP celebrated its 50th anniversary in 2022 in Stockholm, Sweden. Source: https://www.unep.org/environmental-moments-unep50-timeline
