Thomas and Benjamin  highlighted the lack of data as an area of concern related to assessing loss and damage at 1.5℃. Understanding losses and damages also requires more detail on island-specific losses and damages accruing from anthropogenic climate change impacts. At the moment, such assessments are limited, and most of the small islands have not yet documented these factors in their national adaptation plans or policies . There is a need for specific studies also on biophysical variables and species ; long-term impacts of ocean acidification on species, including relationship to disease outbreaks, and changing breeding grounds of marine species and impacts on fisheries and marine-based livelihoods; incorporating biophysical feedback and interconnectivity of environments into models; and more detailed datasets
