 This year has been the hottest in over 100,000 years. We're running out of time to act on climate change, but new data reveals a way forward. We've all seen the headlines. Climate in action is costing lives. Last year, there were record-breaking extreme weather events on every continent and at current projections. This is just the beginning. If global mean temperature rises to 2 degrees Celsius, it's estimated that by 2050, heat-related deaths will increase by 370 percent and 525 million more people will experience food insecurity. And we're currently on track to reach 3 degrees Celsius. But data in the new Lancet countdown report reveals that transitioning to a zero-carbon future could still save millions of lives, if we act now.
