This week marks a decade since Hurricane Katrina spun violently toward the coasts of Louisiana and Mississippi, ravaging both states when it barreled ashore on Aug. 29, 2005.
Katrina taught New Orleans and the Gulf Coast many lessons about how vulnerable the region is to natural disaster, especially to sea level rise and storm surge made worse by climate change.

Researchers have discovered unique inscriptions on the wall of a cave in China recording the effects of droughts on the local population over the course of 500 years.
The inscriptions were found on the walls of Dayu Cave in the Qinling Mountains of central China by a team of international experts including scientists from the University of Cambridge in the UK. When there was a drought, people from the local area would go to the cave to collect water and to pray for rain. Some of them recorded the impacts of the drought by writing a graffiti-type scrawl on the yellow rock wall. Seven such droughts occurring between 1520 and 1920 were recorded in this way.
