I have read that a significant fraction of sea level rise is due to the ocean water expanding since slightly warmer water is not as dense as slightly cooler water, which would serve to push the atmosphere up.
The air is warming too, and the expansion of the air will make it less dense, which utterly swamps the effect from the expansion of the water.
That is, the remaining land would have higher value per hectare on average for a few reasons.
Really? I see that the other way around.
Beaches are valuable, and it will take a lot of time or money to make them at their new sites.
Estuaries provide a lot of ecological services and are basically flat. Having them be at the wrong depth will screw up those services.
Many cities (concentrated value) are right down on the water, and it will be muy expensive to save them and enough of their outlying areas that they remain convenient (which was a large part of why they were cities in the first place).
Note: Please see this post of mine for more on the project, my sources, and potential sources for bias.
I have written a couple of blog posts on my understanding of climate forecasting, climate change, and the Anthropogenic Global Warming (AGW) hypothesis (here and here). I also laid down the sources I was using to inform myself here.
I think one question that a number of readers may have had is: given my lack of knowledge (and unwillingness to undertake extensive study) of the subject, why am I investigating it at all, rather than relying on the expert consensus, as documented by the IPCC that, even if we're not sure is correct, is still the best bet humanity has for getting things right? I intend to elaborate on the reasons for taking a closer look at the matter, while still refraining from making the study of atmospheric science a full-time goal, in a future post.
Right now, I'm curious to hear how you formed your views on climate change. In particular, I'm interested in answers to questions such as these (not necessarily answers to all of them, or even to only these questions).
