Near Memphis, the river level was more than 12 feet lower than normal for this time of year." (AP Photo/Adrian Sainz)
Drought Exposes Sandbars Along Rivers, But Experts Warn Of Quicksand-Like Problems. Quicksand, along the banks of the Mississippi River? Good grief. Here's an excerpt from The Washington Post: "A lack of rain in the United States’ midsection in recent months has reduced water levels in some of the nation’s biggest rivers, exposing sandbars that experts warn could be deadly quicksand. Rivers such as the Mississippi and Missouri are typically low in August, but this year’s drought has them at their lowest point in decades. The sandbars that are revealed look like beaches, inviting boaters, fishermen and hikers to venture out. Experts agree that can be a very bad idea."

Long road to recovery
The city has slowly made its way through a long list of repair and rehabilitation projects. Many costs were covered by FEMA or state grants or donations, but the city paid its share, too. The city spent $4.2 million, split between a loan and bonds, on a 2009 street, water, sanitary and sewer repair project."

Tell me about four and five degree changes. What would we see?
"Before climate change, the drought we had this year would have been a one in 300-year occurrence. And it’s now a one in 10 to 20-year occurrence. So, it’s making these things much more common. And as we go further, this drought will become the standard.
How will society react to that? It will be tough.
There are two studies that just came out in the last month that have shown very conclusively that the number of extreme weather events has increased and gotten more severe. One came out of NASA and the other came out of NCAR — the National Center for Atmospheric Research. They didn’t even include this year’s data. It’s not just that this is what climate change is like. This will be a good year in the future."
So, if the climate changes slowly, we could be lucky and still fix things. What if it shifts rapidly?
"If we pass a ‘tipping point’ — like the full release of methane in Siberia — we may not be able to regain control. We can still do something about it right now."
