| Eoin: | Thanks Blair; the smoking gun we needed to demonstrate climate change is for real. Perhaps you could pass this on to the powers that be - whose first action on climate change is a multi million dollar advertising campaign! |

| TheInvisibleLog: | Anything to add about this publicity about the cold end of the Indian Ocean dipole going up 2 degrees in 40 years? If that explains the change in WA rainfall and runoff, then the interesting times in irrigation have just started. |

| Oxoman: | You can't release all the carbon dioxide that has been laid down over millions of years into the atmosphere in a short time and not upset the equilibrium. |

| blairtrewin: | I had a read of the Indian Ocean paper after a journo asked me about it yesterday. The area with the dramatic warming is actually between 40 and 50 degrees S (CSIRO rather misleadingly used the word 'subtropics' in the media release, perhaps because the lead author isn't a native English speaker). In my mind the most significant result was that this warming provides evidence that the southward migration of the westerlies we're seeing in Australian longitudes is also occurring in the Indian Ocean sector.
The subsurface changes in the tropics are interesting but it's hard to tell what they mean (yet) - we don't understand how the subsurface drives the surface in the Indian Ocean in the way that we do in the Pacific, where subsurface warming is normally a precursor of El Nino. |

| candyman: | Surely Hoggster should be able to tell us more about what the subsurface changes in the tropics will mean to the surface temperature? |

| Shep: | what cant the hoggster tell you? |

| hoggster: | good point shep. that'll show em. |

| Milo: | C'mon Blair, Tassie IS the sub-tropics now. It's nearly June and I haven't lit a fire yet here at St Helens (41 deg 21minS)! There were people swimming at the beach last week without wetsuits. |
