Yeah Steve,
Another article with an agenda to do with the November 1993 changes to airspace
procedures.
Much like the absolute garbage about climate change in the media like the
Kilamanjaro article in the Australian yesterday. Yes the snow on Kilamajaro is
disappearing and it is caused by people but it is due to land clearing in the
surrounding areas, which means less evapo-transpiration and drier air being
carried up the mountain by upslope winds hence less snow so the removal rate by
sublimation exceeds the deposition rate, not CO2 induced (or any other kind of)
warming. This has been well known for years.
Macca, get your eyes checked. You obviously missed the numbers down the left of
the graph.
