Your article on scientific advances helping to increase knowledge of emperor penguins in Antarctica was fascinating. However, there are other problems apart from climate change affecting these and other creatures there. Increased tourism is leading to disturbance of the penguins, especially when newborn chicks are about. Litter is an increasing problem, as is waste from ships. Even on some bases, waste-water disposal is an issue. Non-native grasses have come in on people’s boots and there may be other problems not yet identified (11 January, p 36).
Like the rest of the world, Antarctica is suffering from problems caused by people.
