A mapping tool shows what Launceston will look like as hotter global temperatures cause sea levels to rise.
The tool was created by a group of climate scientists and is called Surging Seas Mapping Choices.
It shows the effects of rising sea levels from the year 2100 onwards at two points of possibility. The first is if the Earth heats by four degrees, and the second is if the Earth heats by two degrees.
The map shows that with current levels of carbon dioxide emission, leading to a four degree rise in average global temperature, the Tamar River will swell to encompass Invermay.
The flooded area goes from, roughly, the river bank in the west to Vermont Road in the north and east, to Elphin Road and Cimitiere Street in the south.
It incorporates Seaport, Inveresk including the new university campus, and residential streets.
If the global temperature rises by two degrees, flooding will be more intermittent, in the same area.
Elsewhere in Northern Tasmania, parts of George Town will be submerged in a four degree scenario but not two degrees; the town of Bridport will be fine but Barnbougle Golf Course will not; and St Helens will be almost completely underwater after a four degree rise but partly affected by two.
Elsewhere, with a four degree rise the Hobart Airport will be submerged as will parts of Lauderdale, parts of Smithton, Burnie along the Bass Highway, West Ulverstone, and a large part of Port Sorrell.

"Warming of two degrees Celsius is a long-standing international target, and corresponds to what many would consider successful global efforts to control greenhouse gas emissions," the authors of the map write.
"It also corresponds, in this analysis, to 4.7 metres (15.4 feet) of global sea level rise locked in to someday take place.
"Warming of four degrees Celsius is close to our current path, would represent a breakdown in efforts, and corresponds to 8.9 metres (29.2 feet) of locked-in global sea level rise."
The data the map is based on comes from peer-reviewed scientific research led by Benjamin Strauss and Scott Kulp of Climate Central in collaboration with Anders Levermann of the Potsdam Institute of Climate Impact Research.
The map was created using that data by Stamen Design.
