The primary driver of ocean stratification in climate change is the increase in global temperatures, which affects the temperature and salinity of ocean waters. Warmer surface waters lead to reduced mixing with deeper, cooler layers, creating distinct thermal layers and altering nutrient distribution. This stratification impacts marine ecosystems and can hinder the growth of phytoplankton, disrupting the entire marine food web. Additionally, stratification affects oceanic currents, which play a crucial role in regulating climate patterns globally, further exacerbating the effects of climate change on marine environments.
