Climate change science is centuries, not decades old, and it was pioneered by a woman

The notion that human activities might be warming the planet started coming into focus in the 1960s and ’70s, before a scientific consensus emerged in the 1980s and ’90s. But the rough outlines of the science surrounding humanity’s greatest contemporary threat has a surprising, little-known history that dates back roughly two centuries. This brief animation from BBC Ideas traces our modern understanding of the greenhouse effect through the work of three pioneering scientists, beginning with the US scientist and women’s rights activist Eunice Foote, whose 1856 work on the heat-trapping effects of CO2 was buried for decades before being rediscovered in 2010.

What the Martian surface looked like to Oppy – humanity’s most resilient rover

When NASA successfully landed the Mars Exploration Rover Opportunity – nicknamed ‘Oppy’ – in 2004, the plan was to explore the Martian terrain for 90 days. Through expert engineering and careful handling, Oppy was able to exceed its designed lifespan 60 times over, exploring the planet for nearly 15 years. Over the course of its impressive expedition, Oppy made a number of key geological discoveries and broke several records, including longest off-world distance travelled at 28 miles. Then, in 2018, following one of the most intense dust storms ever recorded on Mars, Oppy relayed its final message to Earth: ‘My battery is low and it’s getting dark.’ This short video from the US filmmaker John D Boswell, also known as melodysheep, uses images captured by Oppy and music composed using the sounds of Martian winds to pay anthropomorphic tribute to the resilient rover – and by extension, those responsible for its awe-inspiring journey.

The ritualised excess of life aboard a cruise ship is tragic and parodic by turns

The cruise industry as it exists today – somewhat affordable, aggressively fun, indulgent by design – is a relatively new phenomenon, rooted in the 1960s, when passenger ships struggled to compete with air travel. After a pivot to all-inclusive pleasure voyages, cruising is now a $45 billion industry, beloved by some for its budget-friendly luxuries and amenities, and bemoaned by others for its environmental toll, treatment of workers, and – as highlighted by the COVID-19 pandemic – health risks.

The observational documentary All Inclusive drops viewers head-first into the strange rituals of tableside conga lines, captain meet-and-greets and pool cannonball contests that characterise the cruise experience. While the Swiss director Corina Schwingruber Ilić’s tongue-in-cheek tone permeates throughout, the film offers more than just an invitation to gawk, as ‘fun’ plays out in a series of over-the-top pastimes, hinting at the economic and social stratification between guests and workers.

One banknote per hour of work – Robert Owen’s utopian reboot of money

The Welsh-born manufacturer and social reformer Robert Owen (1771-1858) was a quintessential capitalist success story, having risen from modest origins to become a wealthy textile manufacturer in Scotland. However, he grew to reject the dehumanising excesses of the system that had ushered in his fortune, writing that Britain’s monetary structure ‘has made man ignorant; placed him in opposition to his fellows; engendered fraud and deceit; blindly urged him forward to create but deprived him of the wisdom of joy’. This led Owen to devise an audacious plan to recentre the financial system around ingenuity, community and justice.

Introduced in 1832, the radical idea was called the National Equitable Labour Exchange – a system of currency built on the idea that labour is the source of all wealth, and that goods should be bought and sold based on the time it took labourers to produce it. While the Exchange lasted only a few years, the idealistic project helped to lay the groundwork for some of Owen’s more successful later reforms, such as shorter working days, with the ultimate goal of a workday based on the principle of ‘eight hours labour, eight hours recreation, eight hours rest’. This brief video essay is part of a British Museum series in which curators examine objects of interest in their collections. Ben Alsop, curator of the museum’s Money Gallery, inspects a note issued by the Equitable Labour Exchange representing an hour of work.

Kerala’s skilled hand-weavers struggle to survive the rising tides of modernity

The Indian-born, US-based filmmaker Natasha Nair’s short documentary In the Wake brings viewers inside the colourful and tactile world of a weaving community in Kerala, the state on India’s southwest coast still recovering from the wreckage of flooding in 2018. The skilled weavers produce textiles for sarees, the traditional South Asian women’s garments, and must fully engage their bodies and minds in their work, the craft of which has been passed down through generations. In addition to natural disasters, the mostly female workers must also contend with competition from power-loom machines producing sarees that can be sold at half the price of their own hand-loomed products. Nair skilfully captures the vivid hues and kinetic sounds of the work, while her brief portrait of craft ponders if the rich tradition of the Kerala weavers can ultimately survive the rising tides of modernity.

Our planet is a tiny porthole, looking over a cosmic sea. Can we learn what lies beyond our own horizons of perception?

If language began with gestures around a campfire and secret signals on hunts, why did speech come to dominate communication?
