Large parts of Sussex will regularly fall below sea level by 2050, according to worrying new data.

We previously reported how much parts of Kent would be underwater if temperatures rise by 4C.

The report from Climate Central explained the severity of the situation - and it looks to be even more dire than we thought.

The US-based news organisations claims the risk of flooding could be three times higher than previously forecast.

There are three main reasons why the sea rises in hotter temperatures.

Huge ice sheets at the poles melt faster than they form from snowfall loading more water around the earth, ice at high altitude melts at higher points and as with all things, heat makes the oceans expand.

Experts say causes of global warming by humans include burning fossil fuels - coal, gas and oil - factory farming and increasing livestock production and deforestation.

Although these will be gradual changes that could take some years before they reach the levels shown on the map, once they are noticeable it will be too late to stop them.

Why are so many people protesting about climate change? Across the world there is an overwhelming consensus among scientists that the actions of humans are making our planet hotter. There is no longer any debate on the fact that without urgent action to tackle the issue of carbon emissions, we will be in serious trouble. Experts agree that the current action by government is woefully short of what is needed if we are going to prevent catastrophic damage to our planet and way of life. Protesters have called on our government to do more to tackle this crisis.

Climate Central also predicts huge parts of Sussex will be hit by annual coastal floods in the next 30 years.

The map shows the majority of the coastline will underwater, with almost the entire seafront from Rye to West Wittering submerged.

It should be noted that these images are based on predictions if we make no cuts to emissions.

The areas of Sussex set to be underwater by 2050

Rye

This worrying climate change forecast could spell the end of Rye altoghter.

Large parts would be underwater including the harbour, golf club, up to Rye Foreign.

Winchelsea

Huge parts of Winchelsea look set to disappear right from the beach up to Brede, and the other way into Rye.

Hastings

Hastings Beach and seafront could be underwater by 2050 but the rest of the town remains largely untouched.

Bexhill

The seafront of Bexhill could be submerged but the most significant disappearance in Behill follows the Coombe Haven in land all the way up to Crowhurst.

Pevensey

As climate change sets in, large parts of Pevensey are set to disappear underwater, including the National Nature Reserve.

Eastbourne

A huge amount of Eastbourne will also be underwater by 2050, stretching quite far inland up to Herstmonceux Castle.

The coastline alone Beachy Head is also predicted to be lost.

Climate Central explained the maps "Areas shaded red reflect places that are lower than the selected local sea-level and/or coastal flood projection Aaccording to the selected elevation dataset. "Red areas must also meet hydrologic connectivity criteria. This refined "bathtub approach" makes mapping numerous scenarios fast and efficient and reproduces potential future sea-level threats well. "However, when coastal floods are added, the bathtub approach becomes less accurate the higher the flood "Maps take neither engineered coastal defenses nor long-term dynamic changes into account. "Due to the error always present in wide-area elevation datasets, as well as the other limitations described here, this map should be regarded as a screening tool to identify places that may require deeper investigation of risk."

Seaford

The coastline in Seaford is also expected to almost disappear.

While a low-level inland stretch following the Cuckmere River up to Drusillas Park looks set to disappear.

Newhaven

Large parts of Newhaven are set to disappear underwater by 2050.

Lewes

A huge part of Lewes is also set to be lost, particularly surrounding the River ouse.

Brighton

Brighton's iconic seafront could be set to disappear

Peacehaven

Peacehaven looks set to get off quite likely in comparison to other areas of Sussex, with just the seafront underwater.

Lancing

A huge stretch of Lancing stretching north is set to be underwater.

The areas affected follow the River Adur all the way up to West Grinstead - wiping out dozens of villages on the way.

It includes places in Steyning and Henfield.

Worthing

A huge part of low-level Worthing looks set to disappear right along the coastline ands quite far inland.

Little Hampton

All along the seafront and around the River Arun, huge parts of Little Hampton look set to be submerged.

Arundel

Following the River Arun north, large parts of Arundel will be underwater.

Pulborough

Following the River Arun even further north, large parts of Pulborough will also be underwater.

Bognor Regis

Bognor Regis is set to be mostly-lost to the climate change-induced floods.

Chichester

Stretching from down in Selsey right up to Chichester, a huge part of West Sussex is going to be lost to the sea.

This includes East and West Wittering, Chichester Harbour, Almodington, Birdham, Donnington and host of other villages and towns.
