From 1970 until 2010, 34.8 million more people decided to move towards the coast of the United States and that population is expected to grow just as sea-level rise and climate change continue to increase the risk of living there. Amy Wold, a reporter with The Advocate in Baton Rouge, Louisiana, covers change and adaptation; locks and floodgates; levees and marshes; communities at risk; insurance issues; and lessons learned.

Amy Wold, a reporter with The Advocate in Baton Rouge, Louisiana, writes about coastal challenges facing the state, including coastal loss, restoration, economics, diversion, the aftermath of the Deepwater Horizon disaster, BP settlements and the RESTORE Act, fisheries impacts — and why protecting and stabilizing Louisiana’s coastline is not just a local issue, but a national one.

Stormwater becomes a big media story during disasters such as floods and hurricane surges, and it's essential to cover the basics then. But there are dozens of related issues that can contribute to the disaster, and covering them in advance can help your audience understand ways of possibly preventing the peak crises.

The atlas — a database actually — is based partly on climate-related changes in tree cover. It maps out current distribution of 147 species and modeled distribution resulting from climate change.

The organization Maplight now offers three additional ways of looking at its data. Over 14 million records cover ties between lobbying money, legislators, and either all legislation or that relating to several environmental topics. This information can help you better cover Congressional election races of interest to your audience.
