The Time for Carbon Labelling is Now

Carbon labelling gives consumers a weapon to fight climate change at the cash register.

What’s Involved with Carbon Labelling

Today, nutritional and content labelling can be found on packaged foods. The Government recently announced plans to enhance those labels. Why, because of concerns that Canadians need to learn more about what they eat so that they can make healthier choices.

Carbon labelling would serve a similar purpose by allowing Canadians to make healthier choices about carbon emissions. A carbon label would let consumers understand the environmental impact of items they purchase and consume. The label would contain the total carbon footprint of the product.

One step closer to providing customized climate control in the office

EPFL researchers have shown that people’s perception of office temperature can vary considerably. Personalized climate control could therefore help enhance workers’ comfort—and save energy at the same time.

Global warming means that heatwaves are becoming ever-more frequent. At the same time, we’re in a global race against the clock to reduce buildings’ energy use and carbon footprint by 2050. This has shone the spotlight on the importance of making the thermal comfort of buildings a strategic and economic priority. And this is the focus of research conducted by Dolaana Khovalyg, a tenure track assistant professor at EPFL’s School of Architecture, Civil and Environmental Engineering (ENAC) and head of the Laboratory of Integrated Comfort Engineering (ICE), which is linked to the Smart Living Lab in Fribourg.

In her latest study, published as a brief, cutting-edge report in the journal Obesity, she highlights the benefits of providing personalized thermal conditioning and heating for each office desk, rather than maintaining a standard temperature throughout an open space. Khovalyg and her team came to this conclusion after the human thermo-physiological data they collected showed that individuals display very different levels of thermal comfort under normal office conditions.

Students get $5 million from Elon Musk for carbon-removal ideas

An XPrize competition funded by Tesla CEO Elon Musk just awarded teams of students $5 million to develop their ideas for carbon removal systems — and it still has another $95 million to give away.

The challenge: Between our cars, factories, and everything else, humans are pumping about 43 billion tons of carbon dioxide into the atmosphere every year.

To combat climate change, we not only need to cut that figure way down, we also need to capture and store a lot of the CO2 that’s already out there.

New ‘future-proof’ method could remove phosphorus from wastewater using bacteria

A recent study from the Singapore Centre for Environmental Life Sciences Engineering (SCELSE) at Nanyang Technological University (NTU) and published in Wa | Chemistry And Physics.

This study is intriguing since one of the results of climate change is increasing water temperatures, so removing phosphorus from such waters will prove invaluable in the future, with this study appropriately being referred to as a “future-proof” method.

Since phosphorus in fresh water often results in algal blooms, removing it from wastewater prior to it being released into fresh water is extremely important. This is because algal blooms drastically reduce oxygen levels in natural waters when the algae die, often resulting in the delivery of high levels of toxins, killing organisms in those waters.

While traditional removal methods result in a large volume of inert sludge that requires treatment and disposal afterwards, this new SCELSE-developed method does not involve chemicals, most notably iron and aluminum coagulants. Using this new method, the research team was successful in removing phosphorus from wastewater at 30 degrees Celsius (86 degrees Fahrenheit) and 35 degrees Celsius (95 degrees Fahrenheit).

The Last Human — A Glimpse Into The Far Future

The Last Human – A Glimpse Into The Far Future.

German animation and design studio, Kurzgesagt, explores the far future of humanity and how our population may change over the aeons.

Given the numerous global threats we face during this century and beyond – from climate change to nuclear war, asteroid impacts and killer viruses – many of us are concerned that humans could go extinct. But there are reasons to be optimistic, according to this latest video from Kurzgesagt. Rather than approaching the end of human history, we may actually be living at the dawn of our species; the mere prelude for a vast and exciting future that lies ahead.

High-Tech Hard Sails Transform Old Cargo Ships Into Racing Yachts

Wing-like rigid sails are leaping from the rarified world of yacht racing to the backs of cargo ships.

There they go again. The firm BAR Technologies has roots in the elite environment of the America’s Cup hyper-competitive racing series, and lately it has been applying its know-how to design rigid sails for cargo ships. That’s right, wind power is making a comeback on the high seas, and the global shipping industry is down for it. Well, beginning to be down for it. Rigid sails for cargo ships are still in the tryout phase, but that could change as Russia continues to pinch the global fuel supply and climate goals kick in.

Berge Bulk Cargo Ship Catches Hard Sails Fever

BAR hooked up with Yara Marine Technologies a while back to bring its “WindWings” rigid sail technology to cargo ships. The latest shipper to take a look is Berge Bulk, which describes itself as “one of the world’s leading independent dry bulk owners with an outstanding reputation for the safe, efficient, and sustainable delivery of commodities around the world.”

Watch NASA’s SpaceX CRS-25 Launch to the International Space Station

SpaceX’s CRS-25 mission is set to lift off atop a Falcon 9 rocket from launchpad 39-A at the Kennedy Space Center in Cape Canaveral, Florida. Launch is targeted for 8:44 p.m. EDT (00:44 UTC), Friday, July 14. The Dragon spacecraft will deliver new science investigations, supplies, and equipment for the international crew, including an image spectrometer to be mounted on the exterior of the station to better understand how dust plumes affect our climate, and a study of immune aging and potential for reversing those effects. It also will carry an investigation from a team of students at Stanford University that will test the process of creating biopolymer soil composite, a concrete alternative, in microgravity. https://www.nasa.gov/mission_pages/station/research/news/spa…highlights.
