Antarctic

Seafloor predators and open-water feeding animals could benefit from climate change.

The climate change discourse rarely looks beyond 2100, writes Pete Dolack. Maybe that's because even at current levels of CO2, we are committed to thousands of years of warming and polar ice melt that will raise sea levels by at least six meters. However the implacable imperatives of capitalism mean there's little prospect of change for a long time to come.

The jostle is beginning for the Antarctic, a potentially lucrative source of oil, gas and tourism.

Increasing numbers of tourists and research centres in Antarctica are bringing with them seeds, spores, lichens and mosses alien to the continent.
