Extreme weather is becoming increasingly common. Most recently, a record breaking heatwave in Greenland has gone viral thanks to the image of sled dogs wading through water where there should be ice. However, relating single weather events to climate change is problematic and, although these instances can act as indicators of a trend and eye-openers for public opinion, it is important to distinguish between single weather events and climate change.

Climate change is drastically altering the weather patterns and ice conditions that enable emperor penguins, the icons of the Antarctic, to reproduce. The Halley Bay colony, the second largest in the world, in the Weddell Sea has failed to raise chicks for the last three years, leading to discussions on how to monitor climate change and the ability of animals to adapt in a changing world.
