  • The Global History of Sugar

    This book review in the Los Angeles Review of Books discusses Ulbe Bosma’s book The World of Sugar: How the Sweet Stuff Transformed Our Politics, Health, and Environmentover 2,000 Years.

    Earlier scholarship had established decades ago that “early modern European aristocrats […] decorated their salons with sugar sculptures” while “millions of enslaved men and women, overwhelmingly of African origin, […] were overworked so mercilessly on Caribbean plantations that they regularly lost fingers, arms, or even their lives when they collapsed on whirring mill machinery or fell asleep atop boiling vats of sugarcane juice.” 

    According to the reviewer, “Bosma breaks some new ground” by adding to previous scholarship: 

    The World of Sugar brings Asia to the forefront, particularly India, China, and—a little later—the Indonesian island of Java. A sophisticated sugar economy existed in Bengal and North India by the time Marco Polo visited in the 13th century. It employed professional boilers and entrenched systems of monetization and wage labor within the village economy. […] Ming China became a global hub of sugar trade, with cane dominating the landscape, and with new technological innovations—perhaps introduced by Egyptians in the early Islamic era—increasing the efficiency of refining. Elsewhere, Barbarossa, fresh from crusading in the Holy Land in the mid-12th century, brought skilled Syrians to breathe new life into the sugar economy of Sicily.”

    The reviewer shares some interesting tidbits about the global history of sugar from Bosma’s research: 

    “In the late 1600s, sugar confectioneries were introduced into Siam by a Catholic woman of Japanese and Portuguese descent, Marie Guyemar de Pinha (also known as Marie Guimard in French), who married the king’s Greek prime minister. Two centuries later, a sugar planter like Leonard Wray could effortlessly move between the Malay Peninsula, Natal (in today’s South Africa), and the American South, receiving land in Algeria from Napoleon III and conducting sugar experiments under the auspices of the former governor of South Carolina.”

    Since at least the “early 20th century onward,” the problems with the sugar industry have been far from secret:

    “Sugar was only profitable when churned out in mass quantities: consequently, sugar industrialists deliberately overproduced, which artificially drove down prices (and workers’ wages). Governments, meanwhile, helped save corporate sugar from a race to the bottom. They realized that national sugar industries, increasingly financed by Wall Street and the City of London, were “too big to fail” and thus protected them behind stout tariff walls. Today, national governments spend around $50 billion a year to subsidize the global overproduction of a commodity responsible for serious health epidemics.”

    Apparently, “Bosma is hopeful that movements such as conscious capitalism and green capitalism will prod the global sugar industry into reform: he establishes a parallel with the consumer-driven activism of the abolitionist movement of the 18th and 19th centuries.” But the reviewer argues that “[f]or products of mass consumption like sugar, conscious capitalism remains a fringe movement”: “The abolitionist movement, as Bosma notes, was itself undone by consumer demand for cheaper (and thus slave-produced) sugar.”

     As Bosma’s own scholarship shows, “the abolition of slavery in the British Empire in 1834 was followed, a bit more than a decade later, by the resumption of British mass imports of slave-grown sugar from areas beyond London’s imperial control” like Brazil and Cuba. Similarly, “Saint-Domingue sugar workers might have cast away their chains during the Haitian Revolution, but French planters simply carried those chains across the Windward Passage to Cuba, where they got to work establishing a new, brutal sugar frontier powered by yet more slaves.”

  • Better Understanding Photosynthesis

    According to reports in multiple science publications, such as this one, “researchers from the Department of Energy’s Lawrence Berkeley National Laboratory and SLAC National Accelerator Laboratory, together with collaborators from Uppsala University and Humboldt University and other institutions” have been able to shed more light on “how Photosystem II, a protein complex in plants, algae and cyanobacteria, harvests energy from sunlight and uses it to split water, producing the oxygen we breathe.” 

    As the report goes on to state:

    “Using SLAC’s Linac Coherent Light Source (LCLS) and the SPring-8 Angstrom Compact free electron LAser (SACLA) in Japan, they captured for the first time in atomic detail what happens in the final moments leading up to the release of breathable oxygen. The data reveal an intermediate reaction step that had not been observed before.

    The results, published today in Nature, shed light on how nature has optimized photosynthesis and are helping scientists develop artificial photosynthetic systems that mimic photosynthesis to harvest natural sunlight to convert carbon dioxide into hydrogen and carbon based-fuels.”

  • Adverse Effects of Microplastics on Human Hormones

    This report in Salon covers “a new study published by researchers at Rutgers University” about how “everyday plastic pollution could be endocrine-disrupting.” 

    As the report recounts, “[p]reviously, research suggested that chemical additives used to improve plastics, like bisphenol-A (or BPA), were potentially having all kinds of disruptive effects on human hormones.” But now the “new study suggests that even plastic without BPA can have comparable endocrine-disrupting effects.” 

    An important aspect of the methodology was that “the researchers found a way to successfully aerosolize the particles so they could see what happened to them when inhaled” since “this is a common method of absorption into the body.”

  • Flood Mitigation in New Zealand

    This report in Stuff, a news portal in New Zealand, covers local environmentalist Tom Kay’s presentation to government officials “about the importance of rethinking natural disaster mitigation” in light of “a series of devastating floods” over the past five years.

    It raises concerns about “the country’s preoccupation with draining” wetlands having a direct correlation to increased flooding as wetlands “act as buffer zones, or sponges.” 

    Straightening rivers and lining them with stopbanks are said to have “proven disastrous for wildlife and humans alike” as river straightening has destroyed “natural habitats for many fish species” and stopbanks “ultimately elevate water levels above the floodplain.”

    Deforestation, which causes “more water to flow off hillsides,” combined with all the above factors, “has created the perfect storm” resulting in more frequent and more devastating floods, the report argues.

  • The Urgent Need to Significantly Reduce Carbon Dioxide Emissions

    In this article for Nature, climate scientist David Ho re-iterates his long-standing argument that while there is no denying “the need to develop CDR (carbon dioxide removal) methods over the longer term”, urgently cutting down emissions is important because currently available CDR methods will not remove enough carbon dioxide to be able to compensate for the levels of emissions. 

    Ho argues: “We must stop talking about deploying CDR as a solution today, when emissions remain high — as if it somehow replaces radical, immediate emission cuts.” 

    This is necessary because: 

    “Developing methods to verify that CDR works is a major challenge. It will be many years before we have the science to tell us which methods work and whether they harm or benefit the environment.”

  • Exxon's Climate Change Predictions and Climate Change Denial

    This piece by Grist is a useful short introduction to the oft-quoted fact that oil and gas corporation ExxonMobil historically funded some of the most accurate climate change predictions long before most of the world was talking about climate change. And yet, they went on to fund and spread climate change denial in the public domain for decades, knowing full well that said climate change denial was not backed even by their own research.

  • US Media's Coverage of the Latest IPCC Report and the Willow Project

    Media Matters has put out this piece condemning the coverage (or lack of it) in US corporate TV news on the latest report of the Intergovernmental Panel on Climate Change (IPCC) and the controversial Willow project, an oil drilling project in Alaska. The report claims  “national TV news mostly failed to contextualize the Willow project’s recent approval within the framework of the IPCC report.”

    Talking of the expected role of the media in such matters, the report says:

    “National TV news has the potential to shape public opinion and drive action on climate change and therefore has a crucial role to play in holding the fossil fuel industry and politicians accountable for their role in exacerbating the crisis. Making these connections is one of the key actions climate correspondents can take whenever they are asked to discuss major climate news.”

    The main conclusion of the report is that “the overall lack of coverage of the IPCC report and the failure to connect it to the Willow project represents a missed opportunity to demand accountability from the fossil fuel industry and the Biden administration for its continued support for new fossil fuel infrastructure.”

  • Using AI to Detect Patterns in Animal Communication

    This article published by the World Economic Forum delves into the potential of AI analysis of “the vast amounts of animal communication data that is being collected with increasingly sophisticated sensors and recording devices.”

    The process “includes analysing large data sets that contain visual, oral and physical animal communications.”  “The goal,” according to researchers, “is to determine under what conditions an animal produces a communication signal, how the receiving animal reacts and which signals are relevant to influencing actions.”

    To arrive at a richer understanding of animal communication, “AI-powered analysis of animal communication includes data sets of both bioacoustics, the recording of individual organisms, and ecoacoustics, the recording of entire ecosystems, according to experts.”

    Importantly:

    “There are ethical concerns that researchers are confronting, too. This includes, most notably, the possibility of doing harm by establishing two-way communication channels between humans and animals—or animals and machines.”

  • Virus-eating Microorganisms

    Late last year, researchers confirmed the existence of virus-eating microorganisms. The existence of such organisms had been hypothesised earlier. The question that researchers are now seeking answer(s) to is whether these and/or other microorganisms feed on viruses “in the wild,” outside laboratory conditions.

  • Rich Nations Trying to Control Sunlight?

    Climate journalist Sara Schonhardt penned an important report on concerns about how “[r]adical climate interventions — like blocking the sun’s rays — could alter the world’s weather patterns, potentially benefiting some regions of the world and harming others.” 

    The main concerns: 

    “Climate scientists are, by and large, wary of such intervention. While limiting the amount of sunlight that reaches the Earth could rapidly cool the planet, they say, such efforts wouldn’t address ocean acidification and other harms associated with burning fossil fuels, the primary cause of global warming. 

    It’s also unclear how solar radiation management, or SRM, would affect global weather patterns, such as the monsoon rains that are crucial in some regions of the Global South. While it could ease climate impacts in one area of the world, SRM might reduce crop yields or threaten water supplies in another area.” 

    Understandably then “any research on such methods must consider those risks and involve the countries that already bear the greatest impacts from a warming planet.” 

    A United Nations Environment Programme (UNEP) report “recommends a scientific review process based on models and observations that could guide potential research and future governance. If such an assessment determines that SRM deployment would lead to negative consequences, ‘consideration of deployment could be taken off the table,’ the report concludes.”
