Extreme sea level events that used to occur once a century will strike every year on many coasts by 2050, no matter whether climate heating emissions are curbed or not, according to a landmark report by the world’s scientists. The stark assessment of the climate crisis in the world’s oceans and ice caps concludes that many serious impacts are already inevitable, from more intense storms to melting permafrost and dwindling marine life. Half the world’s megacities, and almost 2 billion people, live on coasts. Even if heating is restricted to just 2C, scientists expect the impact of sea level rise to cause several trillion dollars of damage a year, and result in many millions of migrants. “The future for low-lying coastal communities looks extremely bleak,” said Prof Jonathan Bamber at Bristol University in the UK, who is not one of the report’s authors. “But the consequences will be felt by all of us. There is plenty to be concerned about for the future of humanity and social order from the headlines in this report.” The new IPCC projections of likely sea level rise by 2100 are higher than those it made in 2014, due to unexpectedly fast melting in Antarctica. Without cuts in carbon emissions, the ocean is expected to rise between 61cm and 110cm, about 10cm more than the earlier estimate. A 10cm rise means an additional 10 million people exposed to flooding, research shows.

Sea levels could rise by a metre by 2100, according to the latest landmark UN report which warns that many serious impacts of climate change are already inevitable, whether emissions are curbed or not.

Extreme weather of the sort that used to ravage coastlines once a century will happen every year by 2050, according to a United Nations report on the likely effects of global warming. Sea levels are rising twice as fast as during the 20th century as the melting of the world’s largest reservoirs of ice accelerates, the UN’s Intergovernmental Panel on Climate Change (IPCC) said. It added that events such as the North Sea flood of 1953, which killed 300 people in southeast England, will increase in frequency no matter how effectively carbon emissions are curbed.

No parts of the world will be spared from the adverse impacts of rapid sea-level rise, which is likely to impact one billion people by 2050. Impacts range from regular flooding of homes, workplaces and schools, to the complete submersion of the world’s most at-risk island and coastal communities, displacing hundreds of millions of people. According to the IPCC, this sea-level rise will be irreversible.

Nuclear power stations and radioactive waste stores on the UK coast face high risk of flooding by the end of the century. The world renowned Cambridge scientist, Professor Wadham, has warned that 300 cubic kilometres of ice was lost from the Greenland sheet last year. The sheet is “decaying quite rapidly.” Local feedback mechanisms could be accelerating the breakup of the glaciers and recent measurements show that the rate of decline is speeding up beyond any of the projections contained in IPCC reports. Britain’s nuclear power stations are sited on our coast and, once built, new ones could like Sizewell B could be producing electricity for sixty years. Hinkley Point is due to be built by around 2026 and there is a queue of others waiting to get the go ahead. That takes us right into the era of considerable sea level rises. David Crichton, a flood specialist and honorary professor at the hazard research centre at University College London, noted: “Sea level rise, especially in the south-east of England, will mean some of these sites will be under water within 100 years. This will make decommissioning expensive and difficult, not to mention the recovery and movement of nuclear waste to higher ground.” This assessment was based upon 2009 figures, but projections have got worse since then. The 2018 Factsheet endorsed by Defra notes that: “The UKCP18 sea level projections are consistently larger than in the previous set of UK climate projections, UKCP09 (see Lowe et al, 2009), for similar emissions scenarios.” This is important because the Office Nuclear Regulation response to climate change in March of this year notes that their plans are still based upon the 2009 projections and they don’t expect this to change until later this year at the earliest.
