Paris banned all cars for a day to highlight pollution issues

Comments Off on Paris banned all cars for a day to highlight pollution issues

Pedestrians and cyclists cheered yesterday as Paris closed all of its streets to cars. The government held a Car Free Day and the streets filled with bikers, walkers, and roller-bladers instead of smog. Paris held a Car Free Day in 2015 and 2016 as well. But this was the first time they extended the boundaries to include the entire city . From 11 AM to 6 PM local time, cars were asked to stay off the streets – with exceptions made for emergency vehicles, taxis, and buses. The Paris City Council hosted Car Free Day, together with collective Paris Sans Voiture , or Paris Without Car, which is behind the city-wide car-free idea.

The government’s statement on the day said one of the Car Free Day’s objectives was “to show that cities can and must invent concrete solutions to fight against pollution” coming from road traffic. They encouraged people to travel by scooters , skates, bikes , or walking . The symbolic event also brought results. The government said Airparif Association conducted independent measurements during the Car Free Day using sensors and a bicycle outfitted with measuring instruments. They saw “an increased decrease in nitrogen dioxide levels along major roads” and “access roads to the capital.” Meanwhile, the Bruitparif Observatory looked at noise with the help of 11 measurement stations. They saw sound energy decreased 20 percent on average, as compared against a regular Sunday. Via Paris and Associated Press/NBC News Images © Henri Garat – Mairie de Paris

San Francisco’s Wave Organ captures the sounds of the sea to make haunting music

Comments Off on San Francisco’s Wave Organ captures the sounds of the sea to make haunting music

A symphony of strange and haunting music made from the waves can be heard at the tip of a jetty in San Francisco. Part sculpture, part musical instrument, the Wave Organ is an unusual land art installation that harnesses the rhythms of the water. Created by Exploratorium artists Peter Richards and George Gonzalez, the wave-activated sound sculpture is set atop the salvaged remains of a demolished cemetery and is one of the city’s best hidden gems. Installed in 1986, the Wave Organ is a somewhat obscure landmark, often overlooked due to its hard-to-find location at the end of a jetty east of the St. Francis Yacht Club. Making the trek out there, however, is worth it. Surrounded by stunning 360-degree views of the San Francisco bay, the environmental artwork harnesses the pulse of the sea through 25 PVC and concrete pipes located at various elevations that transmit the sounds of crashing waves and gurgling water to elevated openings for listening. Related: Incredible ‘Sea Organ’ uses ocean waves to make beautiful music The Wave Organ is best heard during high tide, but can still be enjoyed at other times of the day though the gurgling rhythms will be much quieter. The music of the bay, which is made by waves slapping against and pushed through the pipes, is relatively subtle. Visitors will need to sit and let their ears attune to the environment to fully enjoy the performance. Carved granite and marble salvaged from the demolished crypts of the city’s former Laurel Hill Cemetery provide plenty of seating.

Rocks discovered in Canada hold the oldest evidence of life

Comments Off on Rocks discovered in Canada hold the oldest evidence of life

3.95 billion-year-old rocks could offer the oldest evidence we’ve found for life on Earth . A team led by the University of Tokyo found graphite in Labrador, Canada that they think is biogenic, or produced by living organisms. They contend this is the oldest evidence of life, as opposed to microfossils found earlier in Quebec , saying the dating process used in the latter was highly controversial. In March, the journal Nature published the findings of an international team of researchers who’d found fossils in Quebec that they said could be between 3.77 and 4.28 billion years old. Now, nine scientists at institutions in Japan say they’ve actually found the oldest evidence of life on this planet, and it’s in 3.95 billion-year-old rocks. Related: World’s oldest fossils discovered in Canada – and they’re 4 billion years old These researchers found graphite in sedimentary rocks. Tsuyoshi Komiya of the University of Tokyo said, “Our samples are also the oldest supracrustal rocks preserved on Earth.” Phys.org pointed out the Quebec fossils were found in a similar formation. The Japan team measured the isotope composition of the graphite to find it was biogenic, although the identity of the organisms that produced the graphite or their appearance are mysteries. Komiya said the team could work to identify the organisms by scrutinizing “other isotopes such as nitrogen, sulphur, and iron of the organic matter and accompanied materials.” They can also analyze the rock’s chemical composition to try and figure out the organisms’ environment . Other researchers, like geochemist Daniele Pinti of the University of Quebec at Montreal, seem impressed by the new team’s findings and process. He told CBC News, “For the moment, it looks very convincing.” Phys.org said that should the discovery be accurate, it would mean life sprung up on Earth a geological second after the planet formed around 4.5 billion years ago. Nature published the new study this week. Via Phys.org and CBC News Images via Wikimedia Commons and Tashiro, Takayuki, et al.

Comments Off on What an island state taught the world about sustainable development

Hawai’i is the United State’s most isolated populated landmass, but its experiences, approach and solutions to sustainability can resonate through the world. The island state is internally navigating the challenges of balancing economic growth, energy independence, economic stewardship and community resilience. Furthermore, it is still strongly committed to the Paris Agreement on climate.
