Global warming discussion IV

[Red Baron Farms]

I've been reading a bit about soil sink methods lately. Seen it suggested that lots of marginal farmland could be a good low-hanging fruit for conversion into carbon sinks. Don't know enough about the economics or the science to judge, but it sounds reasonable.

Yes Marginal soils are a low fruit because we don't need to take on King Corn.

As outlined in the film, decisions relating to which crops are grown and how they are grown are based on government manipulated economic considerations rather than their true economic, environmental, or social ramifications.[1]

But consider this, arable ground is vastly more productive than marginal land. The really prime bits of the best of the best even more so.

This does include carbon sequestration via the Liquid Carbon Pathway (LCP).

So of course there is a bigger battle when we attack the buffer stock schemes that monopolize the best ground and are destroying it bit by bit.

Land Degradation: An overview

But that bigger battle is also proportionately bigger potential returns too. 5-20 tCO2/ha/yr is a sequestration rate based on relatively poor land. Your results may vary.

Satellite data confirms ‘calving’ of trillion-tonne, 5,800 sq km iceberg from the Larsen C ice shelf

No effect on sea level to be expected -but a negligible one owing to halosteric changes-. However, now the ice front around the Bawden Ice Rise has been left exposed to open water sort of 270° instead of 180°. I remind the reader that both Bawden and Gipps ice rises are the reason Larsen C Ice Shelf is pinned down. If the ice around those rises disintegrates (another loss like today's would suffice, no matter in small chunks and not the massive one that got the headlines) the remaining 80% of the whole shelf would disintegrate in a few years and the massive volume of land glaciers that this shelf holds would follow, adding some +7 cm (3-inch) to the sea level rise just by itself, probably duplicating in excess the actual rise of 3 mm a year (1/8 of an inch) during more than two decades, with the aid of other similar but much less important going-on developments.

But it's an ill wind that blows nobody any good. As sea rise almost translates in a similar rise of the water table in areas like Florida, massive state troubles are to be experienced in a state that was instrumental in making Donald C*** president.

Interesting that it happened in the middle of Antarctic winter.

Fortunately, it is happening now, when the Antarctic sea ice extent is less than 3 million square kilometres below this year's maximum (by the way, to date, second lowest on record). Otherwise dumb-as-**** ill-intentioned immoral denialists* had it pegged as a weather or seasonal event and not as the structural event it certainly is.

When a member of a family losses a leg below the knee, his or her life changes, as well as the lives of those in the family do. Well, Larsen C has lost 10% of its body and that is instantly having repercussion on the way the family of land glaciers flows into Larsen.

It would be interesting to learn about the possible changes in the lines of tension that interference images will be showing during the next year, as the calving left the ice line in a way tension have been displacing towards both ice rises as the crack grew.
