A new study on global streamflows has just been announced via press release by NCAR. Here is how the press release opens:

Rivers in some of the world’s most populous regions are losing water, according to a new comprehensive study of global stream flow. The study, led by scientists at the National Center for Atmospheric Research (NCAR), suggests that in many cases the reduced flows are associated with climate change. The process could potentially threaten future supplies of food and water.

Here is what the paper actually says:

We emphasize, however, that the actual streamflow and discharge examined here likely include changes induced by human activities, such as withdrawal of stream water and building dams, and thus they are not readily suitable for quantifying the effects of global warming on streamflow

Lets see how many news stories follow the press release rather than the paper.
