Title get your attention? Well, it’s true and I don’t write it lightly. In a paper soon to be published, a group of researchers have run the numbers and found where all the record heat in the waters of the Gulf last summer ended up. The indictment is convincing: The heat was laundered by Hurricane Harvey and ended up all over south Texas disguised as a severe flood. Seriously, here are the …

In the last two days, there have been two laughable claims about sea level rise. The first was yesterday when the Wall Street Journal published a ridiculous piece by Fred Singer claiming that climate change had nothing to do with sea level rise.

Today’s post is written by Sandra M. Eberts, U.S. Geological Survey Hydrologist and Deputy Program Coordinator (Acting), Groundwater and Streamflow Information Program Everyone is talking about infrastructure, especially the high cost of deferred maintenance and reconstruction. If only it were possible to keep infrastructure from degrading in the first place. U.S. Geological Survey (USGS) streamgages can help do just that. The USGS National Streamflow Network has more than 8,200 streamgages—operated …
