| Zusammenfassung |
| We analyze the global sea level budget since 1850. Good estimates of sea level contributions form glaciers and small ice caps, the Greenland ice sheet and thermosteric sea level are available over this period, though considerable scope for controversy remains in all. Attempting to close the sea level budget by adding the components results in a residual displaying a likely significant trend of about 0.37 mm/yr from 1955-2005, which can however be reasonably closed using estimated melting from unsurveyed high latitude small glaciers and ice caps. The sea level budget from 1850 is estimated using modeled thermosteric and inferences from a small number of mountain glaciers. This longer term budget has a residual component that displays a rising trend likely associated with the end of the Little Ice Age, with much decadal scale variability that is probably associated with variability in the global water cycle, ENSO and long-term volcanic impacts. |
