Sea-level rise around the Australian coastline and the changing frequency of extreme sea-level events

摘要: Sea-level rise is one of the well-known impacts climate change. A recently completed analysis available tide-gauge data for period 1950 to 2000 indicates a global average rate sea-level 1.8 ± 0.3 mm per year. For this period, minimum northwest Australia. Here, we find that change relative mean sea level around Australian coastline 1920 about 1.2 There are only two records sufficiently long examine changes in frequency extreme events, Fremantle and Fort Denison, Sydney. both locations, there decrease recurrence interval (ARI) by factors three levels from pre-1950 post-1950 period. We also demonstrate method estimating events combination tides storm surges locations with little or no data. Cairns, 1-in-100 year event increases height 2.5 m 2.9 2050 as result modest future possible cyclone intensity. Equivalently, ARI would 100 years 40 years.
