Florida’s coastal homeowners face a nightmare scenario. Well before a single home is submerged by a rising sea, climate change could have a very real impact on the area’s housing market. South Florida serves as a prescient case study for what happens to the economy when climate change drives price drops. Tonight at 10: climate science. The safe and familiar on-air meteorologist, with little notice by viewers, has become a public diplomat for global warming, marking a major shift in the way Americans hear about climate change. A melting Arctic changes everything. Eight countries control land in the Arctic Circle, but Russia is the one gaining ground. Sea-ice loss means Russia stands to gain access to shipping routes and energy reserves, and a strategic military advantage. The cheap energy revolution is here. The world is getting more energy than ever and spending less for it. Detailed charts from Bloomberg New Energy Finance show wind and solar are now receiving twice as much funding as fossil fuels, and clean energy installations broke new records worldwide last year. The bottom line: Coal will never make a comeback. American farmers are responsible for 9 percent of U.S. greenhouse-gas emissions, and rice produces three times as much per acre as corn and five times that of wheat. A group of farmers in the Mississippi Delta are changing how they cultivate rice to reduce methane emissions, as well as water and fertilizer use. But absent larger incentives, the new methods may struggle to win a wider following. A rare April tropical storm is the latest weather oddity this year. With top winds of 50 miles per hour, Tropical Storm Arlene last week became only the sixth tropical system to emerge in the Atlantic in April since geostationary satellites began watching the basin in the mid 1960s. The electric-car boom is so real even oil companies say it's coming. Total, one of the world’s biggest oil producers, said EVs may constitute almost a third of new-car sales by the end of the next decade. Electric cars currently make up about 1 percent of global vehicle sales, but traditional carmakers are preparing for transformation.  Photovoltaic solar panels sit in an array at the 16-megawatt Visonta solar power station operated by Matrai Eromu Zrt, as the coal power station stands beyond, in Visonta, Hungary. Coal for delivery in Europe in 2017 will fall about 11 percent by December, taking the gloss off the longest rally in year-ahead prices since 2010, according to a survey of traders and analysts by Bloomberg.
