Reader Tim rightly points out that my Georgia rainfall graph is the state as a whole, while the drought is primarily confined to the northern part of the state. Here’s the north-central Georgia climate division. (The northwest and northeast graphs look quite similar.) I think the point is similar. Depending on what time scales you’re …
We’ve got a full-on water war brewing down in Georgia right now, pitting states against one another (Georgia v. Florida), state against the federal government (Georgia v. Army Corps of Engineers) and endangered species against growing cities (Atlanta et al. v. mussels and sturgeon). It’s worth stepping back a moment and considering the underlying definition …
This time it’s not Sherman, it’s the Corps of Engineers, and it has something to do with fish. Via Shaun McKinnon and WaterCrunch, the story of Atlanta’s attempt to get the Corps to reduce its releases from Lake Lanier, which is running dry. That’s a problem, because it’s Atlanta’s primary source of water. The Corp’s …
cattle and water Originally uploaded by heinemanfleck. Here’s one of the simple but classic ways we manipulate water here in the western United States. It’s called a stock pond. You carve out a little hollow in a drainage, pile up the dirt on the downhill side, and presto, you’ve got a water supply for your …
For my Louisiana readers (reader?), Michael Tobis links to some maps showing areas at risk of sea level rise.
This is one of my favorite views of U.S. climate, providing a quick and easy way to squint and get a feel for what’s going on across the entire continental U.S. It’s the USGS streamflow map, with color showing today’s flow relative to the long term mean for this date. Red’s dry, blue and back …
For the climate warriors in the audience, a quiz. Who said this? Mankind has a record of reacting after a disaster strikes. Dams are built after floods, not before. So far in human history, disasters have not taken place on a global scale. Therefore we don’t really have a tested mechanism for dealing with global …
More bad news out of Australia: “There’s no doubt that much of the estimated winter crop is now lost due to the ongoing dry conditions,” Macdonald said Saturday. “Wheat and barley are among those crops hardest hit — as a result we could see everything from bread to beer made in New South Wales cost …
I stumbled today on Kim Hannula’s delightful blog, in particular her post about hiking with her four-year-old son: He pointed to something that looked like white hairs on an over-excited yeti. Fibrous ice crystals, holding up pebbles and leaves and bits of frozen dirt. Every shadowed spot was covered with them, when we stopped and …

So how do “they” know that the climate change we’re seeing is caused by people? There is no big “aha” smoking gun here, which is why the Nobel for the IPCC’s scientists is so appropriate. Our understanding is based on a long and laborious accumulation of little bits of science. Let me cite a single …
