The alarming report released by the Intergovernmental Panel on Climate Change (IPCC) earlier this month made it crystal clear that every country, business and person in the world will need to step up climate action if the world is to limit temperature rise to 1.5°C (2.7°F). Breaching this temperature threshold would bring catastrophic impacts the world has never seen—from even more extreme weather events to coral reef die-off to food insecurity. The upcoming climate change conference in Katowice, Poland in December (COP24) is the single-biggest immediate opportunity for countries to show they’re taking the 1.5°C report seriously.
