To prove its potential, a team in Les Sables-d'Olonne, France is building a hydrogen-powered aircraft, which aims to be the first to circumnavigate the globe. It goes by the name Climate Impulse. So why did the Climate Impulse team decide on hydrogen fuel for the project? The team's aim is for Climate Impulse to attempt its round-the-world flight in 2028, with testing starting in 2026. Watch the video above for a behind-the-scenes look at the Climate Impulse project.

☆ A shift to renewable energy is 'hopeless' without efficiencies, environmentalist says

Daniel Bosma | Moment | Getty ImagesExplorer and environmentalist Bertrand Piccard has called for a renewed focus on cutting energy waste, saying it's "hopeless" to shift to renewables without improving efficiency. "So if we try to replace fossil [fuel] energy with renewables without being efficient, without reducing the consumption, it's hopeless," he said. Another issue Piccard highlighted was that some countries only consider wind and solar as alternative renewable energy sources. Geothermal energy accounted for just 2.7% of renewable energy consumption, while wind power was 13.2% and solar energy was 7.2%. 'Paradox' of China's solar panel oversupplyPiccard also discussed the ongoing concerns about the potential oversupply of solar panels from China to the European market.

Walsh died Nov. 12 at his home in Myrtle Point, Oregon, his daughter, Elizabeth Walsh, said Monday. “I knew we were making history,” Walsh told The World newspaper of Coos Bay, Oregon, in 2010. “There was an opportunity to pioneer,” Walsh told The World. It wasn’t until later they told us what they had in store.”Walsh was born Nov. 2, 1931, in Berkeley, California. Walsh traveled the world, including many trips to Antarctica, where the Walsh Spur pointed rock is named in his honor.

☆ Mariana Trench and Challenger Deep: 6 facts about the oceanic chasm

‘Titanic’ director James Cameron is one of the few people who have visitedFew human expeditions have ventured to the Challenger Deep. Explorer and Texas investor Victor Vescovo said he saw a plastic bag and candy wrappers at the bottom of the Mariana Trench. A trip to the Challenger Deep can put a vessel under pressure that is “equivalent to 50 jumbo jets,” Feldman noted. In 2005, tiny single-celled organisms called foraminifera, a type of plankton, were discovered in the Challenger Deep,” according to NOAA. Given high interest in the Mariana Trench, however, researchers have made several efforts to give increasingly detailed pictures of its features.

☆ How deep is the ocean? Deeper than the highest point on Earth's surface, by more than a mile
▼ + stars: | 2023-06-22 | by ( Jessica Orwig | ) www.businessinsider.com time to read: +4 min

The ocean is significantly deeper than the highest point on Earth's surface. If you took the highest point on land and submerged it, you would still have more than a mile between you and the deepest point in the ocean. The Challenger Deep is the deepest point on Earth. In 1960, oceanographer Jacques Piccard and Lt. Don Walsh descended to the lowest point on Earth, Challenger Deep, at a record 25,979 feet below the surface. Scientists have sent half a dozen unmanned submersibles to explore Challenger Deep including Kaiko, which collected over 350 species on the seafloor between 1995 and 2003.

What lies at the bottom of the oceanWhile what’s considered the deep ocean extends from 3,280 feet to 19,685 feet (1,000 meters to 6,000 meters) beneath the surface, deep-sea trenches can plunge to 36,000 feet (11,000 meters), according to the Woods Hole Oceanographic Institution in Massachusetts. Alessandro Mancini/Alamy Stock PhotoWhy mapping the ocean is so challengingFrom a strictly scientific perspective, touristic trips to the ocean floor do little to advance our understanding of the ocean’s mysteries. “We want to go to the highest, the lowest, the longest.”But only a “very small percentage of the deep ocean, and even the middle ocean, has been seen by human eyes — an infinitesimal amount. “However, 150 years of modern oceanography have led to better understanding of many aspects of the ocean such as the life it contains, its chemistry and its role in the Earth system.”Mapping the ocean “helps us to understand how the shape of the seafloor affects ocean currents, and where marine life occurs,” Rogers added. Researchers say the ocean and the life it contains could provide answers to some of medicine’s biggest challenges, such as antibiotic drug resistance.

The first looked at the twin crises of Covid and climate change as River was born; the second introduced him to Earth Day and what he could do. Watch Weir investigate “How to Unscrew a Planet,” on CNN’s “The Whole Story with Anderson Cooper,” Sunday at 8 p.m. Energy from clean sources, like this windmill in Texas, is heating and cooling more homes in America than ever before. “We call it climate intervention,” Kelly Wanser told me as we sat under bluebird skies and the Washington Monument. So far, it feels like your future will be marked in new stories to frame our wants and needs, and new tools to build Life As We Know It Could Be.
