You've probably seen a multi-colored climate map at least once in school. You may have wondered, fascinated. Was Antarctica really a cold desert? And why was so much of Russia listed as tundra? Almost always, these maps were based on the climate classification system proposed by Wladimir Köppen. The colors are chosen to fit our imagination: Australia with a red desert center, surrounded by a yellow or orange semi-arid rim, and a more lush green climate along much of the coast and inland. But these maps were created for a climate that no longer exists. Our new research shows how quickly climate change has altered these maps – and how they will continue to change. Our web application allows you to see with your own eyes for any country in the world and for different emission scenarios. In Australia, you can watch the hot desert area expand and the temperate areas shrink.
