This video from the BBC talks about how sea level rise caused by climate change is destroying family life in the Mekong Delta in Vietnam. It doesn't seen to be too concerned about the loss of food production caused firstly by salination of the ground long before it is flooded and secondly by erosion of the ground before it is flooded completely. Some of the farmers have already gone from three harvests a year to two.

In a country which imports 50% of our food we should be worried by a loss of world food production. We saw a few years ago how a succession of bad harvests led to Asian countries shutting down food exports. When that happens on a regular basis and is backed up by harvest losses in the rest of the world caused by extreme weather conditions we will have problems importing the food we need in the UK.

And, of course, the Mekong is just one of many highly productive food growing delta areas throughout the world which will be affected this century.

So sea level is rising. How do you measure this? Have you tried measuring sea level rise in Sweden? At what rate is it rising?

There are already major harvest problems. The major grain growing areas: US, Canada, China production down. Pigs: China, disease has resulted in the loss of millions of pigs, and a result is the supply of heparin, used for blood circulation treatment, is in very short supply.

However you will need to concentrate on your AGW in case it slips from the narrative as facts try to indicate otherwise. We must have more renewables so more poor people will become impoverished as their energy prices climb. No doubt they will relish the sacrifice.

There are intermittent harvest problems throughout the world as weather conditions vary every year but the prediction is for more extreme weather and that is what we are getting. This FT article on the insurance industry confirms that.

Here you really are in cloud cuckoo land, woodburner. It has been recognised for a few years now that renewables are the cheapest form on electricity. This table from 2015 shows that and renewables prices have been dropping further since.

Please inform those in Germany their renewable supplied electricity is cheapest.

I didn't know that we were talking about the costs of electricity throughout the world, woodburner. I don't know the actual costs of renewables in Germany but I do know that their most efficient wind turbine is less efficient than our least efficient one is, the one at Green Park, Reading adjacent to the M4. At least that was true about 10 years ago when I visited the Green Park turbine.

Conditions vary in different locations so our maritime conditions mean we have a good wind resource. German continental conditions mean that they probably have a better solar resource than we do.

Germany has masses of brown coal very near the surface, unlike our coal reserves which are now usually very deep, so that is probably their cheapest form of fuel although that doesn't account for the costs of pollution. But then we all know that you don't damn about pollution, woodburner.

I believe that sea levels are actually falling around the northern Baltic Sea due to post-glacial isostatic rebound. Actually, the land is rising faster than the seas are. Kind of like a race if you will.

No one wants to talk about that. It runs against the generally accepted narrative. Folks also want to avoid talking about the Holocene Optimum....which founds good, temperature wise, until they realize it isn't now. Then they call you names because it REALLY doesn't fit the required narrative. Did you know that there were 2 pulses of sea level rise back then, 6-7 meters apiece, and people want to pretend that the sea level rise we have going on now is a bunch and we are all supposed to get our knickers in a twist?

Sea level isn't "actually" falling around the Baltic. Sea Level might be "apparently" falling as the land rises but "actually" both sea and land levels are rising only, as you say, the land is rising faster.

The north of Scotland is also rising while the south of England is falling after the last ice age. So if you live on rising land near the sea you are well off but if you live on falling land you really should move as soon as you can.

As for woodburner's quote, is he just plain ignorant of the facts or is he deliberately trying to deceive?

Indeed. Harlech Castle was built on the shore line 600 years ago

And the villages and tribes along the Bering Strait land bridge are now under 50m of water, back when the sea levels were really rising!

The bay infront of Harlech Castle has silted up which is a different mechanism entirely.
