An oceanographer has warned of a possible rise in global sea levels of up to 1.3 meters by 2100. According to another new study, published in the journal Urban Sustainability, unless fossil fuel emissions are rapidly reduced, rising sea levels could put more than 100 million buildings at risk of regular flooding.<\/span><\/p>\n

The expected rise in sea levels due to global warming could lead to the flooding of several Russian coastal areas in the coming centuries<\/span>,<\/span><\/strong>\u00a0Filipp Sapozhnikov, a leading researcher at the Laboratory of Ecology of Coastal Bottom Communities at the P. P. Shirshov Institute of Oceanology of the Russian Academy of Sciences, told RIA Novosti.<\/span><\/p>\n

According to the scientist’s calculations, sea levels could rise by 0.3\u20130.65 meters by 2100. In a worst-case scenario, this figure could reach 1.3 meters. Long-term models suggest that by 2300, the sea level could rise by as much as 5.6 meters.<\/span><\/p>\n

Sapozhnikov noted that under this scenario, the city of Azov, the southern part of Rostov-on-Don, the coastal area of \u200b\u200bKerch, several villages in northern Kuban, and part of Adler would be at risk of flooding in the Black Sea region.<\/span><\/p>\n\n

In northwestern Russia, coastal areas of St. Petersburg, part of Kronstadt, and virtually all of Sestroretsk will be affected by rising sea levels. In northern latitudes, according to the researcher, the village of Varandey, as well as, to a lesser extent, Naryan-Mar and Salekhard, may be at risk of coastal retreat.<\/span><\/p>\n

The country’s eastern regions are also not immune to such processes. The scientist cited the port of Nakhodka as an example, where future sea level rise could pose challenges to coastal infrastructure.<\/span><\/p>\n

He emphasized that the conclusions are based solely on mathematical modeling and extrapolation of observed climate trends\u2014for now, these are only calculated scenarios that help to imagine possible consequences, but are not a final forecast.<\/span><\/p>\n

According to another new study published in the journal Urban Sustainability, unless fossil fuel emissions are rapidly reduced, rising sea levels could put over 100 million buildings at risk of regular flooding.<\/span><\/strong><\/span>\u00a0This study represents the first large-scale assessment of the impact of long-term sea level rise on coastal infrastructure in Africa, Southeast Asia, and Central and South America at the building level. The team used detailed satellite maps and elevation data to estimate how many buildings would be inundated at various levels of sea level rise over several centuries.<\/span><\/p>\n

Sea level rise is a slow but irreversible consequence of global warming that is already impacting coastal populations and will continue for centuries.<\/span><\/p>\n\n

The study examined sea level rise scenarios of 0.5 to 20 meters. It found that with a rise of just 0.5 meters, which is projected to occur even with significant emissions reductions, approximately three million buildings could be inundated. In scenarios with a rise of 5 meters or more, which is expected over several hundred years if emissions continue unabated, the impact increases dramatically, placing over 100 million buildings at risk. Many of these buildings are located in densely populated, low-lying areas, meaning entire neighborhoods and critical infrastructure, including ports, refineries, and cultural heritage sites, would be affected.<\/span><\/p>\n

The researchers say these findings provide important information for urban planners, policymakers, and local communities working to prepare for inevitable sea level rise. The study’s interactive map, publicly available via Google Earth, allows decision makers to visualize which regions are most impacted. These data can be used to develop climate change adaptation strategies, such as building protective infrastructure, adjusting land-use planning, or, in some cases, implementing managed retreat.<\/span><\/p>\n

At least moderate sea level rise is inevitable, researchers say, and the sooner coastal communities can begin planning to combat its impacts, the better their chances of continued prosperity.<\/span><\/p>\n

The island nation of Tuvalu is preparing to relocate all 11,000 of its citizens due to rising sea levels and increasing storms.<\/span><\/strong><\/span>\u00a0An agreement with Australia to gradually accept climate visa migrants will be in effect from 2023.<\/span><\/p>\n

Tuvalu’s average elevation is just 2 meters above sea level. Rising temperatures are leading not only to melting ice but also to more intense storms, which are already flooding the islands. According to mail.ru, by July 2025, the Australian Commission had received nearly 9,000 applications for resettlement\u2014almost the entire adult population. According to researcher Jane McAdam of the University of New South Wales, combined with other resettlement programs in Australia and New Zealand, up to 4% of the country’s population could leave annually, and nearly half the population within a decade.<\/span><\/p>\n

While the resettlement process is underway, Tuvaluan authorities have begun 3D scanning the islands to preserve a digital copy of the lost landscape and cultural sites. This is an attempt to preserve the disappearing country and leave a mark on its history.<\/span><\/p>\n

According to the United Nations Development Programme, by 2050, coastal cities with hundreds of millions of residents will face frequent flooding. The UN already estimates that sea level rise is affecting approximately one billion people worldwide.<\/span><\/p>\n<\/i> Comment on Facebook* The owner of the Meta company is recognized as extremist in Russia and is banned.<\/span><\/a>\n\n","protected":false},"excerpt":{"rendered":"
