Melosira arctica, a species of algae found in Arctic sea ice, has been found to contain microplastic particles in concentrations ten time

In a recent study conducted by researchers from Korea and the USA, the correlation between a warmer Arctic and extreme winter weather in midlatitude regions has been established, but the impact of global warming on this link is unclear.

The extent of Antarctic sea ice has registered a new historical minimum after it was reduced to 1.91 million square kilometres on February 13, according to data from the National Ice Data Center and Snow Protection Agency (NSIDC).

The ice in the Norwegian Arctic is contaminated with alarming levels of perfluoroalkyl and polyfluoroalkyl substances (PFAS). 

An Australian expedition is in the process of drilling 2.6km below Antarctica's Dome C camp to find tiny air molecules some 1.5 million years old. The last time they were in atmosphere, homo erectus was figuring out how to use fire to cook and stay warm.

NASA's Earth Observing System has revealed that Antarctic sea ice lets in enough light for hidden phytoplankton to flourish in the Southern Ocean.
