11. 2 things raise the sea level: ice that is currently on land, and the warmer oceans

While floating ice doesn't raise sea level, if the ice caps in Greenland and Antarctica melt, they run into the oceans. Yes, warmer oceans expand, so the level rises. The two effects are fairly close, it's thought.

Thermosteric sea-level rise was estimated to account for approximately one-quarter of the observed rate of global sea-level rise from 1961 to 2003, contributing 0.32 ± 0.12 mm yr-1 down to 700 m depth and 0.42 ± 0.12 mm yr-1 down to 3000 m depth. For the last 10 years of that period (1993–2003), the contribution of thermal expansion was estimated to have increased to 1.5 ± 0.5 mm yr-1 above 700 m and 1.6 ± 0.5 mm yr-1 above 3,000 m, about half of the observed rate of global sea-level rise.

The IPCC Fourth Assessment Report estimated that losses from glaciers and ice caps contributed 0.58 ± 0.18 mm yr-1 to sea-level rise from 1961 to 2003 and 0.77 ± 0.22 mm yr-1 from 1993 to 2003 (Bindoff et al., 2007), with the most rapid ice losses occurring in Patagonia, Alaska, northwest United States, and southwest Canada (Lemke et al., 2007).
