Sea levels could rise by more than one metre by the year 2100 and 5m by 2300 if global emissions targets are not achieved, according to a study.
Scientists at Nanyang Technological University (NTU) in Singapore modelled projections from over 100 international experts for the global average sea level changes based on two climate scenarios.
In the low emissions scenario, in which global warming is limited to 2C above pre-industrial levels, experts estimate a rise of 0.5m by 2100 and 0.5m to 2m by 2300.

In a high emissions scenario where global warming rises by 4.5C, the estimates surged between 0.6m and 1.3m by 2100 and 1.7m to 5.6m by 2300.
The study, which was published in science journal Nature , notes that melting ice shelves in the Antarctic and Greenland ice sheets are the “largest potential contributors” to global mean sea level rise, as the biggest reservoirs of land-based ice on earth.
“Reference postulates that ice cliffs become unstable at elevations higher than 90 metres above sea level, facilitating the collapse of ice sheets during warm periods” the study states, noting that the Antarctic ice sheet is "particularly vulnerable to this process".
It adds: “The multimeter global mean sea level rise (GMSL) rise projected by some experts… would expose up to hundreds of millions of people to coastal flooding and devastate coastal ecosystems.
“However, the expert projections also clearly illustrate the potential for evading such large GMSL rise through successful reduction of emissions.”
The study was a collaboration between researchers from NTU, the University of Hong Kong, Maynooth University in Ireland, the UK's Durham University, Roward University and Tufts University in the US, and the Potsdam Institute for Climate Impact Research in Germany

Fatou, 30, comes from a family of farmers approximately 20km away from the village of Bousra where she now lives with her son Ibu. Her husband grows rice during the rainy season and the rest of the time performs duties as a marabou (fortune teller). She joined the Ampa Awagna agricultural camp for two weeks in July 2019. She says that prior to enrolling on the course, the lack of knowledge in how and when to fertilise her crops resulted in extremely low yields. Fatou explains: “I wasn’t doing anything before I got married but I started market gardening after I came here. I was farming vegetables before but I had some challenges. You can really see the difference in my smallholding now.” She earned £150 for her family selling her recent crop for New Year celebrations. “I now want to get more land and grow my business”.

Djifanghor, 27, is a single mother who lives alone in the village of Niaguis with her mother. After her father died in 2008 her eldest brother was forced to work away to protect the family income. “I don’t have a husband or a boyfriend," she says. "The father of my daughter has gone away so life is challenging raising her on my own. The most difficult part is to be able to provide her with what she needs when she asks." Djifanghor jumped at the chance to learn how to farm the land – she says agriculture is her passion and her vegetable garden. “I’ve been involved in the Ampa Awagna project for a year and prior to enrolment, I had no idea how to set up a vegetable garden. I have just started the vegetable garden and so far I have only sold lettuce. I am also growing chard, carrots, tomatoes and onions on the small plot of land donated from a Catholic church nearby. The bishop tells all his parishioners to come and buy from me”.

Belange, 23, lives in the village of Soutoure, near Kolda. Her parents have always traditionally farmed rice & peanut crops but have noticed the rainy season is unstable – sometimes there is more rain and sometimes there is not enough. “This year it has rained so much, the field flooded and we have lost the rice we were growing. We harvested half the yield of rice we would normally have”. Despite being heavily pregnant she works from dawn to dusk in her lush market garden, tending her chickens and her pigs. Having excelled at the initial 2-week agricultural training camp at Ampa Awagna, Belange was asked to complete the 50-day intensive agricultural camp. She adds: “I am earning much more than I did before the training. I’m growing tomatoes, peppers and chillis and I have much more output. Our life is better now – we don’t need to get help from others or have to ask people for money.”

Elie, 27, along with her family fled Oussouye in the Ziguinchor Region of Senegal in 1998 at the height of the conflict. She recalls stories of how the rebel groups lit fuel around shelters and make-shift homes and those residents who tried to escape were shot. “I still hear the crying and screams of those who perished … that is still what I have in my mind”. Elie holds a masters’ degree in law and would like to become a magistrate, but it is very hard for her to continue at university as it requires a lot of money and she doesn’t have a business to fund the next phase of her studies. “So I’d like to get these agricultural skills from the Ampa Awagna course, start my own business and return to studying later when I have the money.” “In my village we use to grow rice but due to the impact of climate change, we grow far less than before. We can’t find enough land to do what we need to do, as the sea level is rising.”

Fatou has learnt from the Ampa Awagna project how to transform her vegetables into juice to sell and dreams of one day having her own company and employing others. “The money I get from my market garden is not enough but it’s better than nothing.” “The biggest challenge I have supporting our family is food – having enough for everyone to eat. We have porridge in the morning and then rice for lunch and supper. We have some rice to eat but not enough to sell.”

Her father was killed in 1995 during the conflict when she was just 4 years old. “A lot of people were killed on the same day in my area, houses were destroyed and several families were forced to move away. “My schooling was affected – I felt ashamed when the others talked about their fathers and I didn’t have one. It all affected my studies.” She explains how hard the period was for her family, in particular her mother. “She used to drink alcohol as she said it was the only way to forget the ‘bad souvenirs’ (memories) from that day.” Cezi is one of 11 family members at home. Cezi has been managing a large poultry farm and has now written a business plan so that she can set up her own farm. “I had a passion to work with chickens for a long time but I had no opportunity to do it.

Until now Bouya has been totally dependent on her uncle for support. “I’ve just completed the agricultural training camp at Ampa Awagna and I am now planning to develop my own smallholding. The plot of land belonged to my father. My idea is to start growing okra, lettuce, tomato and cucumber – okra is a great crop because it is resistant to the heat. “I dream of one day of having a very big vegetable farm and living back in my home.

Laurentine, 26, runs a smallholding of pigs near Kolda. She is using the new farming methods she learnt on the Ampa Awangna camp and is extremely positive about the future. “Before the training, we used traditional methods. The programme taught me the modern way is to keep them in the shelter as when they wander around they can bring back diseases”. She now has 40 pigs and hopes in the next 10 years to move to a much larger holding where she wants 200-300 pigs. “If you feed the pig well and it fattens up in 18 months then you can sell a big pig for its meat for 35,000 – 50,000 CFA [£54 - £76], but if you don’t feed it well it can take 2 years to get to this size. So for us, the challenge is finding food for the pigs. If we had enough we could start killing them and selling the meat – there is really good money this way.”

Professor Benjamin Horton, who led the survey, said : “The complexity of sea level projections, and the sheer amount of relevant scientific publications, make it difficult for policymakers to get an overview of the state of the science.
“To obtain this overview, it is useful to survey leading experts on the expected sea level rise, which provides a broader picture of future scenarios and informs policymakers so they can prepare necessary measures.”
Co-author Dr Andra Garner, an assistant professor of environmental science at Rowan University, said: “We now that the planet will see additional sea level rise in the future. But there are stark differences in the amount of sea level rise experts project for low emissions compared to high emissions.
“This provides a great deal of hope for the future, as well as a strong motivation to act now to avoid the more severe impacts of rising sea levels.”
Dr Niamh Cahill, of Maynooth University, added: “This international study is based on the informed opinions of 106 sea level experts and underlines the critical importance of pursuing a low emissions policy to limit sea level rise.”
Current global emissions targets under the Paris Agreement seek to limit global warming to 1.5C and aim to strengthen participating countries’ abilities to deal with the impact of climate change .
But a number of countries are not on track to meet their obligations, while Donald Trump has withdrawn the US - one of the world's leading carbon emitters - from the agreement entirely.
