There was a report on the BBC Breakfast programme today (Friday 23 September) about the threat of rising sea levels to historic castles on our coast. The BBC bleated that these castles, which had protected Britain's coasts for hundreds of years, were now being destroyed by rising sea levels due to climate change. The BBC claimed that "scientists have predicted that sea levels could rise by a metre by the end of this century".
This reminded me of a BBC documentary Earth Under Water made by the BBC in 2010. In this documentary the BBC presented two scenarios - a 2-metre sea-level rise by 2100 and a 5 metre sea-level rise by 2200. Using these two 'scenarios' the BBC showed the terrifying consequences for coastal cities and low-lying land from these predicted sea-level rises.
I guess the one positive one can take from the two programmes is that the useless BBC have reduced their prediction of sea-level rise by 2100 from 2 metres to a mere 1 metre.
More BS from The BS Broadcasting Corporation
But let's test whether a sea-level rise of 2 metres or even 1 metre by 2100 is credible.
Here's a table of sea-level rises from 1880 to 1980:

- the sea-level is rising somewhere between 10cms and 12cms per hundred years. We have just 78 years till the year 2100. Yet at the current rate, it would take about 1,000 years for the sea level rise by 1 metre and around 2,000 years for the sea level to rise by 2 metres. So the idea that the sea level could rise by 1 metre (or even 2 metres) in the next 78 years is complete nonsense
- the sea level is rising by different rates at different locations and is even apparently falling by 37cms per century around Scandinavia. I realise that climate activists don't have any common sense and prostitute scientists-for-sale will say anything that the highest payer wants them to say, but hopefully most readers know that, when you take a bath, the water spreads out evenly and cannot rise more in one area of your bath than in another
It's a pity that nobody at the BBC has read my book There is No Climate Crisis. If they had, they would know what's really happening and stop making their wildly-exaggerated, nonsensical claims of impending climate catastrophe. Here's just a small excerpt from my book about supposed rising sea levels:
The changes, or more accurately apparent changes, in sea levels are also partly due to factors like Tectonic Plate Movement, Glacial Isostatic Adjustment, Post-Glacial Rebound and subsidence due to water abstraction around major cities. Tectonic Plate Movement is, of course, the continual movement of the Earth's tectonic plates which give us earthquakes and tsunamis. Glacial Isostatic Adjustment has been going on for at least two million years. Massive glaciers grow and then melt, alternately depressing the Earth's crust and then releasing it again. As we are now in an interglacial, which has led to melting ice, Scandinavia is slowly rising. Hence, the sea level at Stockholm appears to be falling.What about rising CO2?
The Post-Glacial Rebound, which is causing much of the East Coast of North America to sink, occurs because large areas of Canada and America were weighed down by massive ice sheets in the last Ice Age. When that ice melted between 26,500 and 7,000 years ago, land in the centre of the North American began to rise while land around the periphery sank in what has been described as a 'sort of sea-saw effect.' Hence sea levels at the East Coast of America seem to be rising faster than in many other areas of the world. Meanwhile in California on the U.S. West Coast, around 8 million of the state's 40 million inhabitants are believed to live in areas where the land is subsiding probably partly due to Tectonic Movements and partly due to subsidence caused by increased water abstraction.
Looking at the table above one of the largest apparent sea level increases has been 30 cms in 100 years at the East Coast of North America where the land has been sinking due to Post-Glacial Rebound. The sea level for Scandinavia has apparently 'dropped' by 37 cms in 100 years as the land has risen due to Glacial Isostatic rebound. A National Land Survey of Finland study completed in early 2021 calculated that the South Coast of Sweden was rising by at least 1 mm a year, further north the uplift was 2 mm to 3 mm a year and in central Finland the land uplift might be as much as 8 mm to 9 mm a year.
Jakarta is thought to be subsiding by 25 cm a year largely because of groundwater extraction. Houston is sinking as the oil wells beneath it are depleted. Bangkok's and Shanghai's skyscrapers are weighing the two cities down. London is slowly sinking partly due to water abstraction and partly due to Post-Glacial Rebound which is causing Scotland to slowly rise, like Sweden and Finland, after having been weighed down by glaciers during the last ice age.
A report by scientists in 2019 suggested that the real sea level rise due purely to thermal expansion caused by global warming was just 0.7 mm a year: 'Sea level rise by thermal expansion is likely less than 0.7 mm/year........Subsidence is main contributor of sea level rise in many areas of the world.'
And just to finish off today's blog. Here's a simple chart comparing rising sea levels with rising levels of atmospheric CO2. Hopefully it's clear that there is no relationship between the two:

David Craig spent most of his career working for some of the world s best and worst management consultancies. After writing two whistleblowing books, RipOff and Plundering the Public Sector, about how consultants take millions from businesses and government departments while delivering little of value, he was blacklisted and so left the profession.
Since then, he has written several books about government corruption, incompetence and waste, including SQUANDERED: How Gordon Brown is wasting over one trillion pounds of our money and FLEECED: How we've been betrayed by politicians, bureaucrats and bankers, both of which won the Hammond Whiteley journalism award. He is also the author of The Great European Rip-Off and PILLAGED! How they re looting £413 million a day from your savings and pensions.
His latest book Greed Unlimited: How Cameron and Clegg protect the elites while squeezing the rest of us exposes the lies, deceit and greed of the Cameron/Clegg government.
He uses his website to try to inform people about how the ruling elites of politicians, bureaucrats and bankers are fleecing them and to expose the incompetence and lies of those who have power over us.
