What causes the Baltic swirls more frequent appearance? Please elaborate on your answer.

A satellite image of the Baltic Sea wondered scientists, if a phenomenon of sea snot mattered in the Marmara Sea, would happen there. A confirmation revealed that it is not sea snot but a swirl of conifer pollen. Warmer weather creates more carbon dioxide in the air which encourages conifers growing around the Baltic to produce more pollen emitted in the air and shown swirls.
