Coastal erosion will produce more historical discoveries like the remains of shipwrecked sailors, say experts.
It follows the discovery of a skeleton, thought to be from a 17th or 18th Century mariner, in Cornwall.
A number of other sites around England have revealed human remains, buried near where they were washed up.
"Increased storminess and rising sea levels" means we are "more likely" to see further such burials exposed, said Devon county archaeologist Bill Horner.
The discovery of a skeleton in November at Trevone near Padstow in Cornwall is among a number of cases that have been discovered in the county, including the remains of a suspected shipwrecked mariner at Sennen near Land's End in 2013.
All remains are thought to be pre-19th Century and some sites have remains of clothing such as waistcoats and bone and pewter buttons.
Remains of at least six suspected shipwreck victims were revealed by coastal erosion in Wales in 2019.
Archaeologist Mr Horner told the BBC: "I'd say, given what we are seeing in terms of increased storminess and rising sea levels, that we are more likely than not to see further such burials exposed around our coastline."
After 1808 the Grylls Act decreed that drowned remains washed ashore should be buried in consecrated ground.
Prior to the act, remains were buried unceremoniously on the nearest cliff to the spot the deceased came ashore.
Win Scutt, properties curator at charity English Heritage, told the BBC: "You just found a body on the beach who had been swept in by the tide.
"You didn't know whether they were Christians, so you couldn't put them into a Christian cemetery, so they're often buried on the beaches, or close to the beaches."
Anyone discovering remains must report them to the police, who would decide if a criminal investigation was required before they could be handed to archaeologists for analysis and reburial.
Mr Scutt said: "Skeletons have been turning up on our coast for many years, but because of coastal erosion, because of climate change, we're actually seeing an increase in these.
"So where you've got low-lying deposits where burials could easily take place in Devon, Dorset, Cornwall, and throughout the South West, where it's a convenient place to bury somebody at some stage, those are now being exposed."
