Rising temperatures worldwide are changing not only weather systems, but – just as importantly – the distribution of water around the globe, according to a study published today (March 14, 2016) in the journal, "Scientific Reports."Analysis of more than 40 years of water samples archived at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire tells a vivid tale of how the sources of precipitation have changed. Over the years, there has been a dramatic increase, especially during the winter, of the amount of water that originated far to the north.
