Story highlights Snowstorms can occur on Mars only at night High pressure turns carbon and hydrogen into solid diamond rain on ice giants (CNN)Can you imagine how beautiful it might be to witness snow falling on the rust-colored surface of Mars or a steady rain of glittering diamonds on blue Neptune? No, these aren't images from Prince or David Bowie's lyric journals or scenes from some galactic version of "Game of Thrones." Rather, two studies published this week suggest what weather might be like on Mars, Neptune and Uranus. Martian snow by night The Phoenix Mars Lander detected snowfall on the Red Planet in 2009 using a laser instrument to observe how the atmosphere and surface interact. But the other rovers and landers that we've sent to Mars haven't been equipped with this tool. Aymeric Spiga, a researcher at the Laboratoire de Météorologie Dynamique in Paris, wanted to take those observations from the Phoenix Lander and apply his expertise in numerical … [Read more...] about Martian snow and diamond rain: Wild weather in our solar system
Story highlights Heat waves will be responsible for 99% of weather-related deaths in Europe by 2100, a new study says Climate change will be the dominant driver of these disasters (CNN)By the end of the century, two out of three people living in Europe will be affected by heat waves, coastal floods and other weather-related disasters, largely due to global warming and climate change, according to a study published Friday in the journal Lancet Planetary Health. That's 350 million people in 31 countries subjected to an increased risk of death and health hazards. Overall, weather-related disasters are expected to cause 152,000 deaths a year in Europe between 2071 and 2100, jumping from 3,000 weather disaster-related deaths a year between 1981 and 2010. Deadly heat waves becoming more common due to climate change The researchers estimate that 99% of future weather-related deaths will be due to heat waves. That could very well cause a spike in cardiovascular disease, … [Read more...] about Weather disasters to impact 2 out of 3 Europeans by 2100, study says
It is the shortest day of the year, but for holiday travelers, it could feel like one of the longest. As of late afternoon, 5,000 flights had been delayed within, into, or out of the United States, and another 300 had been canceled, according to flight tracking data. Travelers should check their flight status, and here’s what to do if your flight is canceled. At least two major airlines with hubs in the New York City area, JetBlue and United, waived rebooking fees for some fliers traveling through the metropolitan region’s airports. Though a partial government shutdown looms after midnight, the Homeland Security Department will mostly not be affected. The 53,000 agents employed by the Transportation Security Administration will be at work, and they will be joined by air traffic controllers and aviation and railroad safety inspectors. All will have to work without pay. Mild Start to Winter The stormy weather coincides with the arrival of winter at 5:23 p.m. in the … [Read more...] about Poor Weather Spoils Getaway Day for Holiday Travelers in U.S.
(CNN)There's an old adage that says you can't change the wind but you can adjust your sails. It's a lesson for life, but racing sailors have got this down to a fine art as they seek incremental gains in performance. Follow @cnnsport From dinghy sailors reading the wind as they race around a short course, to circumnavigators hitching a ride on pressure systems barreling around the planet, harnessing the weather is a fundamental principle in sailing. And knowledge equals power. In the super high-tech world of the America's Cup, micro analysis of climatic conditions is becoming increasingly important as hydrofoil technology becomes even more advanced. And, although foiling fever has gripped the world of sailing over the last decade or so, the giant multihulls that rose out of the water to "fly" over the surface on hydrofoils at the 2013 America's Cup in San Francisco were a game-changer.

(CNN)Heavy rainfall flooded roads and train stations across Sydney on Wednesday as Australia's largest city suffered its heaviest November downpour in 34 years. More than 100 mm (four inches) of rain fell in less than 24 hours across the city, leaving morning commuters trudging through inundated subways on their way into work. A severe thunderstorm warning was issued by the Bureau of Meteorology on Wednesday for the city and surrounding areas, while some trains and ferry services were canceled. Stunned Sydney residents posted photos and videos to social media, some of which showed cars driving through rising flood waters as high their car windshields. "We have a low pressure system which is lingering over the coast and this has caused quite a lot of significant weather events over New South Wales generally," meteorologist with the Bureau of Meteorology Rosemary Barr told CNN.
