Varied responses to CRS in the China seas have been observed for small pelagic fishes  and cephalopods . The winter and summer SSTs have shown evidence of decadal variability with abrupt changes from cold to warm in substantial association with climate indices to which coastal cephalopods in the China seas respond differentially, with some benefiting from warmer environments while others respond negatively . In the western and eastern North Pacific marine ecosystem, it is indicated that groundfish may suffer more than pelagic fish . Habitat Suitability index models using SST, chlorophyll-a, sea surface height anomaly  and sea surface salinity , as well as fishing effort, strongly indicate that Neon flying squid is affected by interannual environmental variations and undertakes short-term migrations to suitable habitat, affecting the fisheries . The 2015-2016 El Nino was found to impact coral reefs of shallower regions  in South Andaman, India, more than those beyond 20 m . On the southeast coast of India, with bleaching largely mediated by the SST anomaly and during the recovery period, macroalgae outgrowth has been observed  indicating impacts on the benthic community . In the South China Sea, the increase in SST was found to be higher than predicted in recent decades, while the pH decreased at a rate of
