Standing room only at the Charmouth local school tonight for the talk by Andy Ford, a geographer from Bournemouth University. What we all wanted to know was how much more of our area of outstanding natural beauty is going to fall into the sea, and when. Even newcomers to the area like us, are acutely aware that the coast around here is notoriously unstable. Because there was a massive cliff fall last year, which even attracted the attention of the national media. Which I chronicled in my blog at the time. That fall was much nearer to Lyme Regis than to Charmouth. But since the fall blocked access from Lyme Regis the readers of the newspapers and the television viewers flocked to Charmouth.
Some of them were fossil hunters, who knew that most of the fossils on this Jurassic coast, have long since been harvested, so that on bank holidays you can spend all day looking for them, but, if you want to take one home, you have to buy it from the local shop. But a new cliff fall brings down more fossils. But most of the scaveneners were notsomuch interested in fossils, as in the icons of the 1950s. These were hurled down on to our beach, because the 2008 landslide started at an old council rubbish dump at the top of the hill. I took a picture of an old motor car engine, but what had the visitors squealing with delight, was the variety of 1950s bottles, which apparently are now collector’s items.
Unsurprisingly, Andy Ford, did not tell us what we most wanted to know. Because, as a serious academic, as opposed to those academics who will do anything to get themselves a mention in the media, Ford kept emphasising that coastal erosion is a ‘complex’ problem. He refused to give us easy answers.
For instance, when he was a asked a question about whether global warming meant that the problem we were facing was much worse, he prefaced his answer, with ‘if the forecasts are correct’. Because, he knows, as I know, that these forecasts are ‘probably’ correct, but they are forecasts. And as anyone who reads the Murdoch press and the right-wing press in the US knows, there are other fully qualified academics, who are prepared to proclaim that ‘global warming’ is a scare story.
He then went on to say that the threat from global warming was from the predicted rise in sea levels. (That predicted rise would indeed demolish much of Charmouth probably including my bungalow half-way up the hill. But it would also drown my flat in London in happy Hampstead. This is in brackets, because it is me editorialising. Not Andy speaking.)
My wife, like many of the people of Charmouth, was disappointed with the talk. What she wanted to know, was what was happening on Stonebarrow Hill, which is the hill directly above the beach in Charmouth, where my grandchildren play when they are visiting. Were they, and us at risk, of that falling down on our heads, one stormy day?
Andy Ford, made it plain, that his research study, is monitoring Black Ven, the area on the Lyme Regis side, and that he could not give us any information on Stonebarrow, where there was a much smaller cliff fall recently.
But, unlike my wife, I felt I had learnt important things I wanted to know from his talk, about this place, which I have made my home.
First the nasty cliff fall was probably not due to coastal erosion (i. e. the sea encroaching upon the land, which is what will happen with global warming) but by ‘ground water’. The massive cliff fall in 2008 happened after serious rain, and on a very stormy night, when my bungalow was rocking in the storm.
But, note the ‘probably’. Because that is a sign that you are listening to an academic, who knows that his research study, although done to the best of his ability, may not tell you the whole truth.
Second, again in response to questions, the Bournemouth University team, said that the cliff falls were ‘probably’ not caused by the activities of the hordes of fossil hunters, but by ‘natural forces’. So I shall not stop my grandson, smashing away with his geological hammer.
He is ‘probably’ not likely to start a ciff fall.
The evening began with a contribution from Andy Ford’s side-kick, Sam Scrivener, who gave us the context. This area of the coast, into which I have put the savings of my lifetime, is ‘the largest landslide in Europe’, which neither the estate agent, nor the surveyor, I paid to look at the bungalow, told me. (But, I did not buy in total ignorance, because the solitary academic qualification in my cv is a degree in Geography, and although that was 54 years ago, I have not forgotten everything I was taught then.)
Sam also said that our neighbourhood is
of outstanding universal value because it shows the geology
In other words, those same cliff falls which worry us, are revealing the history of the earth. And helping the scientists to devise strategies to cope with the problems we face today.
We are still subject to the cyclical climatic changes, which produced the ice ages. But we also have to face the consequences of the effects on the environment of our own power stations and motor cars, etc, etc.
And the debate about how we deal with that will go on and on and on. But we need to have that debate informed by those the geographers and the geologists, who are still working away to increase our knowledge about those mighty ‘natural forces’.
