Scientists have developed a method that allows them to identify so-called climate change "fingerprints" in daily weather observations - and it found consistent evidence of global warming every day since late March 2012. Using climate models and statistical learning techniques, a team of researchers at ETH Zurich in Switzerland were able to identify climate change's "fingerprint" in global daily mean temperatures, which had been calculated from measurements collected in locations across the world. The researchers highlighted that while local daily mean temperatures might fluctuate significantly year-on-year, global daily mean measurements show a consistent trend towards global warming. They say their...
