The latest Intergovernmental Panel on Climate Change report is a grim, yet unsurprising, reminder of the catastrophic effect global heating is having on our planet. The message from leading climate scientists is clear: action is needed now. Not tomorrow, not next year, not by the end of the decade.
Even drastic carbon reduction today that limits temperature increases to the 1.5C agreed in Paris will alter the world we live in for ever. The IPCC concludes that every fraction of a degree more will edge us towards tipping points that will leave deep scars on our planet.
