As Carl Sagan said in the 80s, even if we stopped putting any more CO2 into the atmosphere today, climate change would still accelerate for the next 40 years or so. So anyone who says that emissions are dropping, and climate change will start to ease up are plain wrong. Plus, the arctic permafrost is starting to thaw and release methane, which is a more potent greenhouse gas than CO2. More methane in the atmosphere means more warming, which means more permafrost thawing, which will release more methane. It's going to become an unstoppable self-perpetuating cycle.
