4.4 mm/yr (2010-2015) 3.4 mm/yr (1993-2015) 1.2 mm/yr (1930-1992) 0.6 mm/yr (1900-1930) 1.2 mm/yr Hansen et al., 2015; Church and White, 2011; Nerem et al., 2010; Hay et al., 2015; Yi et al., 2015; Watson, GRL, 2016

Greenland and Antarctica are both losing ice very rapidly

Greenland is melting

West Antarctica is collapsing

Marine and Groundwater Inundation

Waikiki storm drains back up at high tide.

Intersection of Kalakaua Ave & Kapiolani Blvd Highest tide of the month, Water table is 2 ft below the ground

Rainfall at high tide causes flooding

Rainfall at high tide causes flooding

High Wave Flooding

Coastal Erosion

Hawai‘i Climate Adaptation Initiative (Act 83, 2014) • Establishes an Interagency Climate Adaptation Committee (ICAC) Initial focus is to develop a Sea Level Rise Vulnerability and • Adaptation Report (due Dec., 2017) Develop a statewide Climate Adaptation Plan • “Climate change is the paramount challenge of this century.” Governor Neil Abercrombie State of Hawaii, Office of Planning
