The present article, starting with the lead section, is obscure and rambling. Wikipedia:Manual of Style/Lead section says that the lead should be clear and accessible and “should identify the topic, establish context, explain why the topic is notable, and summarize the most important points, including any prominent controversies” It should say what sea level rise is and what it is not. In addition, several references are old: IPPC Fifth Assessment Report (AR5, 2013-14) is good but earlier versions are probably not. Current citations are vital.
Now for an attempt at constructive input. How about something like this for the lead paragraph?
Sea level rise refers to an increase in the volume of water in the world’s oceans, resulting in an increase in global mean sea level. Seal level rise is usually attributed to global climate change by thermal expansion of the water in the oceans and by melting of Ice sheets and glaciers on land. Melting of Ice shelfs or icebergs at sea do not raise sea levels.
Sea level rise at specific locations may be more or less than the global average. Local factors might include tectonic effects, subsidence of the land, tides, currents, storms, etc.
Sea level rise is expected to continue for centuries.[2] Because of the slow inertia, long response time for parts of the climate system, it has been estimated that we are already committed to a sea-level rise of approximately 2.3 metres (7.5 ft) for each degree Celsius of temperature rise within the next 2,000 years.[3] IPCC Summary for Policymakers, AR5, 2014, indicated that the global mean sea level rise will continue during the 21st century, very likely at a faster rate than observed from 1971 to 2010.[4] Projected rates and amounts vary. A January 2017 NOAA report suggests a range of GMSL rise of 0.3–2.5 m possible during the 21st century.[5]
