White band disease to remove "Pterois" from the Gulf of Mexico. White band disease prevalence in the Caribbean varies seasonally. It is more active in summer and less prominent in winter, suggesting that warmer water temperatures contribute to the waterborne spread of the disease to affected corals. The impact of climate change and increasing carbon emissions only serve to heat the waters surrounding the coral reef ecosystems, which maybe allows for the spread of diseases such as white band disease and others. The severity of marine diseases such as white band disease increase for several reasons. Elevated water temperature can cause corals physiological
