This field is for validation purposes and should be left unchanged. Figure 1. Although we now know it's happening, how high will it go? “Maps are a universal language that everyone can understand. Learning by sharing: case studies of adaptation in Australia and beyond . Layers (0) Management Regions. This data has shown a more-or-less steady increase in Global Mean Sea Level (GMSL) of around 3.2 ± 0.4 mm/year over that period. The actual impacts may vary as this model does not take account of existing sea walls, storm surge, erosion or other local factors, and it does not include consideration of any future protective action that may be taken. Draw Transect. That's 183 cm. All light blue areas on the map show the parts of Australia most at risk of flooding. The committed sea level rise from Antarctica even at 2C represents an existential threat to entire nation states. Zoom into a familiar location, create a point, and share your story. The 0.8 metre sea-level rise value is based primarily on the median value of the RCP 8.5 greenhouse gas emission scenario which is ‘business as usual’ where the current rate in the growth of greenhouse gas emissions remains the same. It also considers the projected variation in the local sea-level rise rate of northern Australia. There is a clear pattern of sea-level change that is also reflected in patterns of ocean heat storage. The CSIRO, on behalf of the Sydney Coastal Council Group (SCCG), has undertaken modelling of coastal inundation under future sea levels. Sea level stabilised over the last few thousand years, and there was little change between about 1AD and 1800AD. With parts of Australia's east coast identified as global hotspots for rising sea levels, areas of the Gold Coast are expected to be hardest hit due to the density of development and population. Sea level rise is speeding up. A BETA version of the Coastal Risk Australia interactive webmap has been made openly available and charts the majority of Australia’s enormous coastline to show how sea level rise could impact Australia under a number of different climate scenarios. Climate Central. Greenwash - Companies falsely claiming green cred. Sea Level Rise – Science and Synthesis for NSW (PDF 1.5 MB) Coastal impacts from sea level rise. Global mean sea level (GMSL) has risen about 19 cm since 1900, at an accelerating rate. You can identify areas that will be affected by a low sea level rise (0.44m), a medium sea level rise (0.54m), and a high sea level rise (0.74m). Sign up now to stay up to date about all the news from Spatial Source. Sea level began to rise again in the 19th century and accelerated again in the early 20th century; Satellite altimeter measurements show a rate of sea-level rise of about 3 mm/year since the early 1990s - a further increase in the rate [top] The last 140,000 years. Animals at Melbourne's Sea Life Aquarium will probably be the only ones happy with the projected sea-level rise. Effect of sea level rise or sea level change can be seen on the map. They illustrate an event that could be expected to occur at least once a … Scientists are forecasting sea levels will rise between 0.4–1.1m over the remainder of this century depending on how rapidly the world reduces emissions of greenhouse gases. Between 1900 and 2016, the globally averaged sea level rose by 16–21 cm (6.3–8.3 in). Maps are available to show three sea level rise scenarios: low sea level rise (0.5m), medium sea level rise (0.8m) and high sea level rise (1.1m). Map of the United States indicating high risk flood areas with sea level rise. This site uses Akismet to reduce spam. They have released Sea Level Rise Maps - 3.2MB for Hornsby Shire that will help residents understand the impact of predicted sea levels. Australia Flood Map can help to locate places at higher levels to escape from floods or in flood rescue/flood relief operation. Sign up to receive our free weekly Spatial Source newsletter. Sea Level Rise. Here, we model the contribution of polar ice sheets to local sea level rise. In June 2011 a supplement to Climate Change Risks to Australia's Coasts was released. Coastal Risk Australia incorporates 3D LiDAR, Google Engine and local tidal data to accurately map how rising sea levels could encroach on cities, towns and beaches under three scientific scenarios. Since the early 1990s, sea level has been measured from space using radar altimeters, which determine the height of the sea surface by me… Of all the impacts from climate change, the projected rise in mean sea level is a concern for management of the coastal zone in the longer term. Click on icons in the map to view sea level rise simulations at specific locations. NGIS Australia built the website based on an earlier model used to map sea-level rise in the Pacific Islands. Stay up to date by getting stories like this delivered to your mailbox. “Our main goal is to raise awareness of how sea-level rise will affect the places we live, but this will also help all Australians prepare for change, from all levels of government, in policy, conservation and community engagement.”.
