Could a singular planet have more than one diverse atmosphere?

I'm making a world which is set on a planet with two smaller "bubbles" of atmosphere at the poles, and a more stereotypical atmosphere that surrounds them. Each of the three atmospheres has a different gaseous composition (one of the smaller ones is mostly Earth-like, with an abundance of oxygen, while the other is mostly Carbon/Carbon Dioxide based; the larger atmosphere is made of thicker, denser gases.) In every atmosphere exists an entirely different ecosystem and set of organisms.

Is this scientifically possible? If not, how close can a planet get to this type of atmosphere?
