This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Conger Ice Shelf- Start of the Conga?
The Conger ice shelf in Eastern Antarctica was relatively small, being 'only' 1200 square km. The ice shelf's complete collapse has not produced huge effects. A NASA scientist involved in the study suggests, however, that the ice shelf's collapse 'may be a sign of what is coming' (https://www.theguardian.com/world/2022/mar/25/satellite-data-shows-entire-conger-ice-shelf-has-collapsed-in-antarctica). The Conger ice shelf collapsed after a record temperatures of -11.8 degrees Centigrade (40 degrees above normal values) was reached on March 18th. It seems likely that other areas of Antarctic ice will also melt. Such a succession of melts could produce a 'domino' effect, elevating sealevels, diverting ocean currents etc. We may be rapidly approaching a tipping point, at which the process can no longer be reversed.
