The Australian Prime Minister Kevin Rudd has ‘changed tack‘ from his post election promises last year in which he said that ‘failure to act on climate change could be disastrous’, and that delaying emission reductions would be “reckless and irresponsible”. Due to the global recession (and presumably other factors), local emissions trading is now halted untill 2011, and of more intrigue, greenhouse gas cuts have been upped 15% to 25% reductions by 2020. See my colleague John Quiggin‘s blog for excellent discussion of conditional & unconditional targets, and 2020 reduction levels. What is worthy of note is this excerpt from the Prime Ministers speech discussing 450ppm as the target for stabilization:
“…the Government has also listened carefully to international and environmental stakeholders committed to realising the best possible outcome at Copenhagen, which is scheduled for the end of this year, in order to achieve the best and most ambitious outcome necessary to stabilise long term greenhouse gas emissions at 450 parts per million, because applied to Australia’s own circumstances long term, that creates the best economic and environmental dividend to Australia, including as I said importantly before, providing a scientific basis for us having a real prospect of saving the Great Barrier Reef.” (Read more)
Ove, you need to comment more on pieces like this. Rudd and Co have continually been saying that “the science says” that 450 is enough to stop the destruction of the reef, and also that 5% by 2020/60% by 2050 will be enough to stay under 450. Seems to me that both of these statements are wrong, right?
