The living-dining space at the heart of a tree grove in bucolic Baden-Württemberg, southwest Germany, gives off strong Flinstones-family-kitchen vibes. Thirty-six big and slender London plane trees ensconce a series of large, rough-edged stone tables and an open oven; the transparent roof above whimsically resembles a turtle’s shell, somewhat creating the illusion of a mysterious Stonehenge-like structure. But the devil is in the details—dining surfaces are impeccably flat, with stone slabs securely fixed atop screw-pipe foundations, while the roof is crafted from fiber-reinforced plastic.
Las Vegas’ evolution is ever apparent as it gears up for Super Bowl 58. What was once considered a sports pariah is now hosting the biggest U.S. sporting event of the year, and the event comes less than three months after the city held a Grand Prix Formula One race. That’s not all — Las Vegas now boasts two new entertainment facilities, the Sphere and Allegiant Stadium, adding new offerings like A-list performers. The total number of visitors climbed to 40.8 million in 2023. Beyond all the fun and gambling, the region has also become popular with relocating businesses and homebuyers. However, there are some significant risks with being a desert city that could hinder Las Vegas’ growth as the planet warms. CNBC traveled to Vegas and met with locals and experts to learn more about Sin City’s explosive growth.

A 2022 National Oceanic and Atmospheric Administration-funded heat mapping study involved a group of 60 volunteers who spread out across Clark County to check the temperatures in different locations during the morning, afternoon and night. The map produced from that data shows that elevated temperatures are worst in North Las Vegas, East Las Vegas and downtown, which can get up to 11 degrees hotter than other parts of the city.

Cities and towns across three continents are in the grip of heatwaves so strong they are breaking records. From Beijing to Rome, people are struggling with extreme weather conditions and heat-related illnesses. The US city of Phoenix has broken a record set nearly half a century ago, of 19 consecutive days of temperatures above 43 degrees Celsius. Al Jazeera’s Kristen Saloomey reports from Clark County, Nevada where heat shelters are nearly full.
Nestled in New York City’s Greenwich Village, Public School 41 differs from its neighboring buildings in a way that’s both profound and only visible from above. Unlike the flat, gray roofs adorning other structures on the street, the school’s roof is a bright, verdant green. Covered in native plants, the vegetation provides an unlikely urban haven for birds and insects. It also acts as a natural stormwater control system and reduces the building’s carbon footprint. When the school’s students were asked how the roof made them feel, they said “free.”
