Paris climate deal: key points at a glance

Governments have agreed to limit warming to 1.5C above pre-industrial levels: something that would have seemed unthinkable just a few months ago.

The 195-nation conference in Paris had been scheduled to wrap up on Friday, but was extended another day after ministers failed to bridge deep divides during a second consecutive all-night round of negotiations.

New research sheds light on mercury pollution in estuaries, food chain

Mercury, which is transformed into methylmercury in water, is a global pollutant that damages human health. Most people are exposed to mercury by eating fish, particularly from open ocean and coastal fisheries. Estuaries act as a repository for methylmercury, storing toxic particulates in both the sediment and water column.
