It is predicted that many places around the globe will be completely under water in the centuries and millennia to come.
Climate change means that as temperatures are increasing, ice is melting and the sea levels are rising.
On the shorter term, this means that places around the world, including in Cornwall, are increasingly at risk of flooding and that cliffs are eroding. On the longer term, it means that some bits of land are doomed to disappear.
According to geologist Edmond Mathez of the American Museum of Natural History, if all the ice covering Antarctica, Greenland and in mountain glaciers around the world were to melt, the sea level would rise 70 metres and cover all coastal cities.
However Mr Mathez explained that not all the ice is going to melt and the Antarctic ice cap has survived much warmer temperatures.
But the sea levels are bound to rise and Cornwall will particularly be affected.
It appears that most of the Cornish coast and the Truro and Hayle areas would be the most affected by the rising seas.
This is according to data provided by NASA and shared via FireTree.
The website provides maps of the areas around the world which will be flooded according to how high the sea levels will rise.
We have selected the maps for +1m, +5m and +60m.
As a reference, sea levels are likely to rise by 0.5 or 1m by 2100 according to the Committee on Climate Change.
If sea levels rise by 1m, as expected by 2100, beaches and cliffs around Cornwall will be affected.
Flooding along River Amble is expected south of Chapel Amble, along the Tamar below Calstock.
Part of Cotehele would be flooded, parts of Par docks and Par Sands Holiday Homes would be submerged.
Parts of Pentewan beach and the piers in Mevagissey and Gorran Haven would be under water.
The south of Point, south of Devoran and the cliff north of Boscastle would be submerged.
Polzeath beach car park, Rock beach, Padstow harbour and most of Fistral beach would be under water.
Part of Towan Headland, in Newquay, would be flooded, turning the northern part of it into an island.
In Newquay still, Trevemper roundabout and the houses around it would be flooded.
Most of Crantock beach and Hollywell Bay and Perranporth beach would be gone.
Part of Portreath seafront and the bay between Godrevy Towans and St Ives and would under water.
The area between Lelant and St Erth and parts of Hayle, Phillack and Ventonleague would be flooded. So would be Newlyn harbour, Penzance seafront and Long Rock.
A part of St Michael’s Mount would be gone.
Par and St Blazey would be submerged and the Southdown area would become an island.
Most of Cornwall’s biggest towns would be under water: Penzance, Newlyn and Marazion, St Ives, Hayle, Porthleven and part of Helston, Falmouth, Truro, Portreath, Perranporth, Hollywell Bay, Newquay, Padstow, Wadebridge, the south of St Austell, Lostwithiel and Looe.
The area between Carbis Bay and Sennen and St Levan would become an island.
The countryside between Roseworthy and Tehidy Country Park would be flooded.
The area between Mullion and St Keverne would be an island.
There would be a large stretch of water between Bodmin and Lanivet and Bodmin and Washaway.
Most of south east Cornwall and the Rame Peninsula would be gone.
The Isles of Scilly would also be under water.

How fast is the climate changing?
While many people suggest climate change won’t affect our generation, certainly governments and organisations around the UK have set 2020 or 2030 as the deadline to make major changes to help combat climate change.
According to NASA: “Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought.
“If the rate of ocean rise continues to change at this pace, sea level will rise 26 inches (65 centimetres) by 2100 – enough to cause significant problem for coastal cities.”
While the Royal Society says: “If CO and other greenhouse gases continue to increase on their current trajectories, it is projected that sea level may rise by a further 0.5 to 1 m (1.5 to 3 feet) by 2100.
“But rising sea levels will not stop in 2100; sea levels will be much higher in the following centuries as the sea continues to take up heat and glaciers continue to retreat.”
