The Antarctic Circumpolar Current is key to the mixing and ventilation of the world’s oceans. This current flows from west to east between about 45° and 70°S connecting the Atlantic, Pacific and Indian oceans, and is driven by westerly winds and buoyancy forcing. High levels of productivity in the current regulate atmospheric CO2 concentrations. Reconstructions of the current during the last glacial period suggest that flow speeds were faster or similar to present, and it is uncertain whether the strength and position of the westerly winds changed. Here we reconstruct Antarctic Circumpolar Current bottom speeds through the constricting Drake Passage and Scotia Sea during the Last Glacial Maximum and Holocene based on the mean grain size of sortable silt from a suite of sediment cores. We find essentially no change in bottom flow speeds through the region, and, given that the momentum imparted by winds, and modulated by sea-ice cover, is balanced by the interaction of these flows with the seabed, this argues against substantial changes in wind stress. However, glacial flow speeds in the sea-ice zone south of 56°S were significantly slower than present, whereas flow in the north was faster, but not significantly so. We suggest that slower flow over the rough topography south of 56°S may have reduced diapycnal mixing in this region during the last glacial period, possibly reducing the diapycnal contribution to the Southern Ocean overturning circulation.

It says that sales rose in only 133 local authority areas and then only by 3.5% on average last year, compared to the year before.The areas worst hit by the slump in property sales and where reductions hit double-digit figures include Eastbourne, Bedford, Runnymede, Gosport, Brighton, Wellingborough and Merthyr Tydfil. The three hardest hit year-on-year last year were Cambridge (-16%), Newcastle-under-Lyme (-16.2%) and Stevenage (-27.5%).A total of 122 areas have seen transactions fall by more than 5%, while 41 local authorities saw sales drop by more than 10% and 11 areas by more than 15%.“It might not be immediately obvious what transaction levels have to do with the housing crisis, but the answer is a great deal,” says Joseph Daniels, CEO of Project Etopia (left).“Lack of housing stock means we’re on a merry-go-round of gyrating house prices in this country [and] this feeds into massive price gains that occur over just a few years, causing people to think of their house as an investment not a home.“When storm clouds gather on the horizon, they then guard their most valuable possession by sitting tight.“It’s easy to forget that there were 231,690 fewer homes sold in the last financial year than a decade earlier. If we had more stock, this boom and bust would be a thing of the past and the sands wouldn’t keep shifting under developers’ feet.”But it’s not all bad news; sales picked up dramatically in several areas including in Chorley, Hull and Lincoln, all of which experienced house sales rising by more than 10% year-on-year. project etopia Runnymede Gosport Joseph Daniels house sales Bedford Brighton Eastbourne Wellingborough and Merthyr Tydfil January 4, 2019Nigel LewisWhat’s your opinion?
