According to a study published today in the journal, "Scientific Reports", rising temperatures worldwide are changing not only weather systems, but the distribution of water around the globe.
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.
This study marked the first time scientists have used specific measurements to demonstrate how water sources are changing, especially in the northeastern United States. This study shows how climate change is altering the spatial patterns and amounts of precipitation where it comes from and where it falls. Such effects can drastically affect the availability of potable water and also contribute to the massive flooding we have seen in recent years.
