When tornadoes touched down in eastern Alabama on Sunday, they killed at least 23 people and caused millions of dollars in property damage — adding another grim chapter to the annals of the most violent of all windstorms. But what exactly causes tornadoes to form, and what makes them so destructive? What is a tornado? A tornado, or twister, is a rapidly rotating column of air that stretches from clouds at the base of a thunderstorm to the ground. Tornadoes can produce winds in excess of 300 miles an hour, but even much weaker tornadoes can devastate an area. Tornadoes are typically 300 to 500 yards wide, though some of the largest ones have spanned a width of more than two miles. Environment Tornadoes typically last no more than a few minutes and travel less than a mile along the ground before a shift in the forces that sustain them causes them to dissipate. But some especially powerful tornadoes travel for dozens of miles, destroying entire communities along the way.

The deadliest tornado to hit the U.S. in six years touched down in Alabama Sunday with winds of 170 mph and a path of 27 miles. It killed 23 people and was part of an early severe weather outbreak with 50 preliminary reports of tornadoes. But while some were quick to point to climate change as a cause of the tornado outbreak, current science isn't definitive about how much climate change influences tornadoes. On Monday, Democratic presidential hopeful Sen. Bernie Sanders posted a warning about climate change and tornadoes on Facebook. "The science is clear, climate change is making extreme weather events, including tornadoes, worse," he wrote.Sanders is correct to say that climate change makes extreme weather worse, although current science isn't definitive about tornadoes. But climate change seems to be shifting the concentration and range of tornadoes, pushing them into more vulnerable areas. In addition, evidence suggests there will be a more favorable environment for … [Read more...] about What we know about tornadoes and climate change
By Julie Zhu and Yilei Sun HONG KONG/BEIJING (Reuters) - The SoftBank-led Vision Fund is in talks to invest up to $1.5 billion (£1.14 billion) in Chinese used car trading platform Guazi.com, two people with knowledge of the matter said. That would mark the latest Chinese deal by the mammoth $100 billion investment fund as it looks to expand in the world's No.2 economy, and would come after it invested 460 million euros in German used car dealing platform Auto1. The fund is likely to invest up to $1.5 billion in Guazi in a deal that would value the firm at $8.5 billion before the investment, according to one of the sources, who had direct knowledge of the situation. The two sources, who were not authorized to speak to media, also said the Vision Fund had in the past few months held talks with Guazi's direct rival, Renrenche, which is backed by Chinese ride-hailing firm Didi Chuxing. Guazi, a consumer-to-consumer used car trading platform founded in 2014, is backed by Chinese … [Read more...] about SoftBank’s Vision Fund in talks to invest $1.5 billion in Chinese used car platform: sources
By Angie Teo TOKYO (Reuters) - The owner of a Japanese sushi restaurant chain on Saturday set a record by paying more than $3 million(2.36 million pounds) for a bluefin tuna in the year's first auction at Tokyo's new fish market, exceeding his own record price of 2013. Kiyoshi Kimura, who owns the Sushizanmai chain, paid 333.6 million yen for the 278-kg (613-lb) fish caught off the coast of northern Japan's Aomori prefecture, or double what he had paid six years ago. "The tuna looks so tasty and very fresh, but I think I did too much," Kimura told reporters outside the market later. "I expected it would be between 30 million and 50 million yen, or 60 million yen at the highest, but it ended up five times more." Saturday's event was the first New Year auction of the Toyosu market, after the famed Tsukiji fish market shut last year to provide temporary parking for the Tokyo 2020 Summer Olympics. Kimura had held the record for top price paid for a single fish at the new year's auction … [Read more...] about Tuna sells for record $3 million in auction at Tokyo’s new fish market
