In a Nature Commentary ("Climate economics: Make supply chains climate-smart") he proposes a community effort to collect economic data on the new website zeean.net.

"Storms, floods or droughts in one place can have considerable effects all around the world,” Levermann explains. “Take for instance the devastating flood in Thailand in 2011: The local impact was calamitous. Its effect on hard-disk production made it also a global event causing a worldwide shortage for months afterwards.”
