The Prime Minister wants to re-engage with the evidence. Good! But she is apparently unable to read the advice of her own “experts”. Or add-up:
“…Global warming will see seas rise by possibly up to a metre by the end of the century — that’s a huge risk to many parts of our country” Extract from Julia Gillard’s 4 July press conference, quoted in The Australian
Several national science authorities including CSIRO have estimated the global mean sea level (GMSL) rise since 1992—when the crucial satellite measurements began— to be approximately 3.2 mm per year. That works out at 29 cm by the year 2100; or just under one foot in the imperial scale. Not even close to a metre.
Yes, sea-level varies from place to place: but that is irrelevant to the case for a Labor/Greens coal tax. The proposed tax addresses a global emissions “problem” because there is no way to affect the local atmospheric composition or the local sea-level.
Note, incidentally, the inconvenient sideways track in graph for the past few years? Warming of the top layers of the ocean has slowed to a stop since about 2001. It may eventually resume warming because the climate is variable over multi-decade periods (ho-hum!).
