Arizona State University and Columbia University research finds that increased flood strikes and outdated flood prediction led to meager payouts for homeowners and massive debt for the National Flood Insurance Program — but there is a way out.
A study in National Science Review identifies a previously overlooked natural source of atmospheric mercury. The researchers show that chemolithoautotrophic microbes can use mercury sulfide nanominerals as an energy source and, in doing so, convert mineral-bound mercury into volatile elemental mercury (Hg0) released to the air. The team estimates this process could emit about 272 ± 135 tonnes of Hg0 per year globally.
