Are there any textures out there of an Earth where all the Icecaps have melted and the oceans have risen?

There are some pictures of The Global Warming Globe 360x on my website. This simulation capability can be turned to your purposes to produce some new shoreline images. Then these shoreline images can be used in Photoshop to mask out the old texture file. This would provide the effect that you want , where the oceans have risen. I am volunteering to make a model of the Earth, flooded to any level you request. Images of the model would be posted so you can use them to make shoreline images and to mask your favorite existing texture.

Link to low resolution images, 1 degree grid of latitude and longitude.
The exaggeration of elevations is 360x, but for your purpose, less is better.

Your wish is my command line.

I am making a model of the Earth in the year 2500 c.e. for Orion's Arm; the water level has not risen very much, perhaps three or four metres only, because industrial carbon dioxide emissions almost completely ceased after oil prices went through the roof in 2030.

Instead of fossil fuels the Earth relies on fusion power, fission fast breeder plants, Ocean Thermal Energy conversion, wind and wave power and solar photovoltaics. Large areas of continental shelf have been converted into new land for agriculture, while floating cities are anchored in the Atlantic, Pacific ans Indian oceans. Some parts of Greenland and Siberia are now warmer and support a much larger population, while the Sahara, Gobi, Kalahari and various American deserts are all to some extent irrigated and made habitable.

It is a big texture, and the most detailed parts of it would need to be on virtual texture tiles- but I haven't found a good guide to making these yet (Bob Hegwood's guide has been taken down for the moment).
Any suggestions?

Here is the North Sea as seen from space in the year 2500.

The new country kown as the North Sea Reclamation project or, popularly 'Neverland' is visble in the centre; also visible is the extent of sea incursion in the Thames, Wash and Humber regions and in Denmark.

That is actually quite an accurate texture; however if global warming were to occur to that extent I would expect the Caspian Sea to get smaller, even dry up altogether.

You will notice that the rise shown in that link is about 70 metres; this would be the rise if all the ice on Antarctica melted. None of the climactic models I have seen suggest that this is likely to happen.
If only the floating ice in the Arctic were to melt then sea levels would hardly change at all.

Wonder what having that bit lump of land in the North Sea would do to the british climate (by affecting winds going over the north sea etc).

Do you consider returning to Britain? ;-)

The prevailing winds in Britain are from the southwest, so the effect probably wouldn't be very much I don't think. Maybe the east coast might be slightly drier, I don't know.

Permanently? Not if I can help it ;).

I thought that sometimes cold winds come over the north sea over the winter?

There certainly is a cold wind from the North Sea at times; that is why Skegness is so bracing.
