Land has been flooded, houses have been flooded, livelihoods have been lost, causing great difficulties for people in looking for a safer future.
It is not only the environment that is affected, rising sea levels also have a significant impact on human rights, economic development, health, culture, the future of many countries and basic human dignity.
Villagers in South Malaita in the Solomon Islands plant mangroves to protect the coastline.
Everyone and almost everywhere is affected, both in developed and developing countries. The ability to act and adapt now will determine whether sea level rise is a manageable challenge or a generational crisis.
What is meant by sea level rise?
Simply put, sea levels are rising due to the impact of climate change caused by humans.
Between 2014 and 2023, global sea levels will rise 4.7 mm a year. In 2024, the record soars 5.9mm.
Concrete cylinders line a beach in the Maldives to protect against rising sea levels.
Even in the most optimistic scenario, seas will likely rise 0.55 meters by 2100; under the worst, ends one meter. A small opportunity but with a big impact exists in the high emissions scenario, which is almost as big as 2 meters by the end of the century.
What caused it?
- Melting of glaciers and ice sheets.
- Thermal expansion; warming oceans actually take up more space.
- About 91 percent Most of the geothermal heat is absorbed by the sea, so as climate warming increases due to increased emissions of harmful gases, future increases in emissions will be hampered.
Human impact
Around 770 million people, about 1 in 10 humans live less than five meters above the high tide line.
The distance is very close and the closeness can already be felt.
- Fresh water wells and agricultural land become salty.
- Flooding damaged hospitals, schools and sanitation systems.
- Increased exposure to waterborne diseases threatens drinking water supplies and contributes to increased psychological distress.
- Fisheries and tourism, which are the backbone of the coastal economy, are being disrupted.
Houses lost to the sea due to coastal erosion in Puerto Rico in the Caribbean.
- Some projections suggest up to 1.2 billion people could become refugees globally by 2050, because people are not only looking for a safer place but also looking for a place to find a new life.
- New evidence suggests that sea level risks may be underestimated in some regions, leaving tens of millions of people more vulnerable than previously thought.
Beyond the physical: cultural heritage, ancestral lands and traditional ways of life are also lost, with real psychological impacts
Price tag
- Damage to coastal infrastructure has exceeded $1.8 trillion.
- Without adaptation, annual global losses could be enormous $1.4 trillion.
- Small Island Developing States are losing out $153 billion to climate hazards between 1970–2020.
- Home insurance premiums in the US jump by 33 percent between 2020–2023 in regions at risk of disasters
- Ports that handle more than 80 percent Global trade is increasingly vulnerable to flooding and rising sea levels, creating risks for global supply chains.
Modern cities such as Guangzhou in China are facing flooding as sea levels rise.
Where is the most risky?
Many countries facing the most pressing risks contribute the least to the emissions that cause sea level rise and often have the fewest resources to respond.
- Small Islands: Several countries in the Pacific face relative sea level rise more than double the global average and remain highly vulnerable to increasingly frequent flooding.
- Lowland delta city: Dhaka, Mumbai and Kolkata, where more than 14 million people are at risk of losing their homes, livelihoods and lives.
- Large coastal cities: Miami, New York and Guangzhou face trillions of dollars in losses if infrastructure is damaged.
Can it be stopped?
Not entirely, some increases have occurred.
But how Lots More will happen depending on the extent to which harmful emissions can be reduced now.
NASA images show a rapidly melting section of the West Antarctic ice sheet known as the Thwaites Glacier.
One flashpoint: Antarctica Thwaites Glaciercovers about 190,000 square km. Its collapse alone could trigger a sudden and irreversible rise in sea levels more than half a meter a real and possible tipping point from which there is no turning back.
Adapt to the inevitable
Moving away from climate-changing fossil fuels is the world’s most important priority to slow global warming and sea level rise, but adaptation measures are also needed now.
- An early warning system so that people can be protected before a disaster occurs.
- Sea walls, mangrove forests, sand dune restoration, and efforts to withdraw communities from threatened areas.
- Better data; many areas still lack basic monitoring of ocean conditions.
- Clarity of legal aspects, including regarding state and maritime zones, if land sinks occur.
Developing countries need estimates $310-365 billion one year for adaptation, but global adaptation funding has only just become available $26 billion in 2023
The main thing is
Rising sea levels feel like an unstoppable force, but how much damage is done, and to whom, still depends on the choices people, communities and governments make today.
Ultimately, increasing adaptation funding, ensuring that countries are not affected by rising sea levels, and making sea level rise a permanent global priority are what is needed to protect people’s homes, histories, livelihoods and identities.
