Climate Scientists Update Global Warming Scenarios: The 1.5C Goal is Slipping

New research indicates that while the most catastrophic climate warming scenarios are becoming less likely due to the rise of renewables, the goal of limiting warming to 1.5 degrees Celsius is now largely unattainable. Scientists are narrowing the range of plausible futures, suggesting a middle path of roughly 3 degrees Celsius of warming by 2100. The updated projections show that carbon pollution is not decreasing fast enough to hit the 2015 Paris Agreement targets. Even the best case scenarios now expect the world to overshoot the 1.5 degree mark, highlighting a gap between current political action and the physics of atmospheric carbon.
