The World Metrological Organization (WMO) claims that long-lived green house gas (LLGHG) concentrations reached new post-industrial revolution highs in 2013. Warming of ocean is three dimensional process. Historical trend has been rising sea levels. Thermal expansion of ocean also contributes significantly to sea level rise. Thermal expansion likely to persist for centuries. Doney . Woods . Hole . Oceanographic Institution. . Rising Atmospheric CO. 2. IPCC AR5 . WG1 Chap. 6. Doney & . Schimel. Ann. Rev. .
