The committed sea level rise from Antarctica even at 2C represents an existential threat to entire nation states. A new tool from APSEA award winning team at NGIS have released a first of its kind tool to allow Australians to visualise how sea level rise driven by climate change will impact their areas. Extreme sea level events (storm-driven waves and surge) also became about three times more frequent during the 20th century. The FireTree Flood app uses Google's mapping tools and Nasa data to work out how sea level … Scientists forecast that in just the next 20 years, the sea will have risen by another 6 inches. The Intergovernmental Panel on Climate Change puts sea level rise projections for Australia somewhere between 50 to 90 centimetres by 2090, relative to the average sea level … In June 2011 a supplement to Climate Change Risks to Australia's Coasts was released. Both the low-end and “worst-case” possibilities were revised upward in 2017 following a review by the U.S. Interagency Sea Level Rise Taskforce. More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017,: 1554 which is a trend of roughly 30 cm (12 in) per century. In 2017, researchers led by the University of Melbourne, Australia predicted sea levels could rise as much as six feet by 2100. The project is designed to monitor sea level around the coastline of Australia. With around 85% of Australia’s population living in the coastal zone, rising sea levels and storm surges will have significant impacts on many of our coastal towns and cities. In Australia the consequences of sea level rise will include increased flooding of low-lying coastal, including tidal, areas and are likely to result in coastal erosion, loss of beaches, and higher storm surges that will affect coastal communities, infrastructure, industries and the environment. The CSIRO, on behalf of the Sydney Coastal Council Group (SCCG), has undertaken modelling of coastal inundation under future sea levels. 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. Sea Level Rise. In Australia, the potential replacement cost of residential buildings exposed to a 1.1m level sea rise is estimated at as much as $63bn. The ultimate goal is to identify long period sea level changes, with particular emphasis on the enhanced greenhouse effect on sea level. Around Australia, and in the Great Barrier Reef, the fastest rates of sea level rise are in the north. NGIS Australia Principal Consultant Nathan Eaton said it was difficult for people to appreciate what rising sea levels in decades to come could mean for their homes, community and the places they love. The study, published in PLOS ONE, Jan. 22, is the first to use machine learning to project migration patterns resulting from sea-level rise. Ackerley et al., 2013, Kopp et al., 2014).Regions and local areas within New Zealand will also be affected differently by vertical land movement and local changes in tides (e.g. 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. This is illustrated by the map (below) showing sea-level trends from 1993 to 2019. NGIS Australia built the website based on an earlier model used to map sea-level rise in the Pacific Islands. Understanding the risks to infrastructure and private property is particularly important for highly populated urban areas. Europe N. America S. America Africa SE. This is more than 50% larger than the average value over the 20th century. Greenwash - Companies falsely claiming green cred.
