Climate scientists hope to be able to tell the world almost in real-time whether global warming has a hand in extreme weather thanks to an initiative they plan to launch by the end of 2015. In recent years, scientists have become more adept at working out whether climate change caused by greenhouse gas emissions is exacerbating wild weather and its impacts around the world, but the task usually takes months. "In the media, we are seeing this notion that you cannot attribute any individual events to climate change, but in fact the science has really evolved over the past decade," said Heidi Cullen, chief scientist with Climate Central. The U.S.-based non-profit science journalism organization is leading the initiative to speed up that analysis alongside the Red Cross Red Crescent Climate Centre, scientists at Oxford University, the Royal Netherlands Meteorological Institute (KNMI) and others. A review of 16 major weather events in 2013, released on Monday, found that human-caused climate change clearly increased the severity and likelihood of five heatwaves studied -- including in Australia, Japan and China.
