Human activity brings invasive species to Antarctica

Human presence in Antarctica has already affected some of its delicate ecology and climate change will make it easier for invasive species to establish themselves. So says a new report which explores the impact of human activity on Antarctica's…

Emperor penguins risk extinction due to climate change

New research shows that Emperor penguins risk extinction by the end of the century if global temperatures continue to rise. Warming will lead to the loss of sea ice around Antarctica. And if that happens, the Emperor penguins will lose the very…

Antarctic sea ice in dramatic decline since 2014
