    Research suggests climate change target 'not safe'

    The results reveal the European Union target of limiting global temperature rise to less than 2°C above pre-industrial levels shouldn't be considered 'safe'.

    From their analysis, the scientists found 263 estimates of the conditions when sediments and ice were laid down during the Last Interglacial, allowing them to reconstruct past temperatures around the globe. To compare the reconstructed estimates with today, they took the Last Interglacial values away from modern temperatures averaged over the period 1961 to 1990.

    The results show temperatures appear to have been more than 5˚C warmer in polar regions while the tropics only warmed marginally; strikingly similar to recent trends. Not only this, but taken together, the world appears to have been some 1.9˚C warmer when compared to preindustrial temperatures. Critically, the warmer temperatures appear to have resulted in global sea levels some 6.6 to 9.4 metres higher than today, with a rate of rise of between 6 to 9 centimetres per decade — more than double that recently observed.

    The higher temperatures seen during the Last Interglacial are comparable to projections for the end of this century under the low emission scenarios contained within the recent Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).

    Professor Turney said: "The results here are quite startling and, importantly, they suggest sea levels will rise significantly higher than anticipated and that stabilizing global average temperatures at 2˚C above pre-industrial levels may not be considered a 'safe' target as envisaged by the European Union and others. The inevitable conclusion is emission targets will have to be lowered further still."

    Can you tone it down a little? It's not safe, I mean 2 C less would be ideal.

    Thank you

    Whats so startling? There they go again with that "oh no the sky is falling" crap again:lol::lol: This is new? There are wave cut terraces and benches and platforms all over the world. Sea levels rose to 230 feet above what they are now and then fairly rapidly dropped down to the present level.

    Oh and here's a real kicker for the alarmists. How many SUV's were out there when the temps were high enough to melt the ice caps all over the world?
