Justin Rowlatt is the BBC’s first climate editor. He reports from the frontline of our changing world, documenting how global warming is reshaping ecosystems and economies. You’ll have seen him on the main TV news, you’ll have heard him on radio and you will have read his articles online. Justin was with the first team to get to the front of the so-called “doomsday glacier” in the West Antarctic - the fastest changing area of ice in the world. If it melts it would raise global sea levels by more than a metre. Justin also leads the BBC’s coverage of the renewable revolution that is transforming how the world generates electricity.
