In particular, increased sea level and temperature threatens the islands and atollswith floods, erosion, groundwater degradation, and coral reef damage (Nurse et al. 2014). Under theRepresentative Concentrations Pathway (RCP) scenarios, by 2100mean sea levels will increase 0.44 m (under RCP 2.6) up to 0.74 m (under RCP8.5) with regional variations that could further increase sea levels in the Pacific (IPCC 2013).
