Sources: 2. Developments: 2. Scientific research indicates that climate change is significantly impacting coastal ecosystems and meteorological patterns globally. In Spain, studies involving the Spanish National Research Council (CSIC) suggest that islands such as Arousa and A Toxa face critical biodiversity threats by 2050 due to land-use changes, invasive species, and urbanization. Additionally, data from the last 41 years shows a 21% decrease in the intensity of sea breezes along the Andalusian coast, which may exacerbate extreme heat episodes. This phenomenon of weakening sea breezes is also being observed in major international coastal hubs, including New York and Shanghai. Meteorologists warn that rising ocean temperatures are altering these natural air currents, which act as a ‘natural air conditioning’ for densely populated areas. The reduction in these cooling mechanisms increases the risk of thermal stress and more intense heatwaves in urban environments. ## Timeline ### 2026-08-22: Climate change threatens sea breezes in coastal cities Climate change may be reducing sea breezes in coastal cities like New York and Shanghai, potentially increasing thermal stress and heat intensity for millions of residents. 2 sources. https://clstr.news/cluster/climate-change-threatens-sea-breezes-in-coastal-cities ### 2026-08-08: Climate change threatens Spanish islands and coastal breezes Climate change is threatening Spanish biodiversity in Galicia's islands and weakening cooling sea breezes along the Andalusian coast, potentially increasing extreme heat risks. 2 sources. https://clstr.news/cluster/climate-change-threatens-spanish-islands-and-coastal-breezes --- Cite as: Climate change impacts on coastal ecosystems and breezes.
