Yes, in a slight slowing of the rate at which it is increasing.
Hard to attribute with confidence since it's a global figure based on pooled local measurements, but so long as you agree that human-caused release of co2 contributes to increasing atmospheric co2 levels, the reduction is a safe assumption.
The depressing part is the reduction needs to be 10x greater, and permanent, and global, for atmospheric co2 to halt it's increase and start dropping.
