The second derivative of CO2 levels turned negative in 2015. In other words, before 2015 we were increasing our CO2 levels by a greater amount every year. Since 2015 we're still dumping more CO2 into the atmosphere each year, but the amount we're dumping every year is decreasing by a small amount.

Obviously, it's not anywhere close to enough and the effects won't be significant until the first derivative goes negative too, but anybody telling you we're doing nothing is selling you panic rather than solutions.
