Abstract Catalase under ultraviolet-B radiation (CATUVB) produces reactive oxygen species (ROS), but the role of that surprising photoactivity in CAT still remains uncertain. On the other hand, it is well-known that CAT breaking down a steady source of hydrogen peroxide (H2O2) becomes inactive due to compound II formation (CII), which results in typical changes in its absorption spectrum. On the basis of CII formation, here I show first that CATUVB produces and breaks down H2O2, via which UVB is converted into heat. I then show that CATUVB thermogenesis accelerates the ice melting and warms the medium. From data to nature, CAT converting harmful UVB into advantageous heat in microorganisms would be responsible for a hidden biogeochemical thermogenesis process under the ozone layer control with effects on sea ice melting and sea surface warming in cold regions.
