   Was in Melbourne a week ago for two days of 45C (113F). The heat radiated off every surface, unreal! The commentary there was that more of these days can be expected with global warming.

   Looking at GW from an Aussie perspective it is fairly scary, more water from cyclones in the north, and extreme dries with bush fires everywhere else. A couple of degrees and the place becomes pretty untenable for inland agriculture, and coastal cities will have water supply problems.

   Meanwhile Melbourne sprawls and everybody needs a car (you could not live without one and expect to get to work etc, its all predicated on automobiles, just like Auckland). The traffic is horrendous and the CO2 generated is huge. It is all a death spiral, they cant leave their cars even if they want to.

     Melbourne also has giant mothballed desalination plants, built when “the science” predicted to rivers to run dry and the dams to empty. Never used and no forseeable need to – but almost bankrupted the state…..

     I have lived in Melbourne for several years without a car, you sell Melbourne’s world-class (and fairly widely used) public transport system massively short with your post! The difference in public transport between Wellington (where I lived previously) and here is absolutely remarkable.

       Visited there a few years back – awesome transport system, although I only stayed in “Zone One”. Traveled by train then tram for more than an hour, no real delays, still only in zone1. On the same ticket.

       In Dunedin, one bus takes half an hour to go through three “zones”, and if you have to change buses you need another ticket.

         Expatriot and McFlock, the public transport in Melbourne was superb as you both say. The issue I saw was that the sprawling size of the city outside a 10km radius of the centre made things very auto centric. From public transport hubs in the suburbs the transit to homes and facilities etc becomes far less easy. The inner city dwellers don’t have that problem but they pay through the nose for proximity to the city in housing costs.

     Interesting that the morons who wrote that post clearly didn’t understand what it was saying and what the implications were.

     What they said was that the effect of climate change on the formation of cloud aerosols was highly uncertain. In other words they had not been able to establish a relationship between cause and effect. Notable skeptics like Singer had been arguing for years that climate change was self-limiting because as warming proceeded there would be more cloud cover from more aerosols.

     To date this has been the only theory they have produced that has *any* scientific validity. This paper just killed that hope.

     Perhaps you and the other “skeptic” morons should stop being so damn lazy and learn enough science to not waste everyones time correctly your sagging logic. You can’t even recognize it when a pet theory by the lunatic fringe of science goes *pfffttt*

     Seems a lot of the hot air going out of Climate Science…..

     Both you and Watts are idiots who can’t read. Actually in Watts case I suspect that he has no interest of getting off the gravy train. He is just venial rather than being willfully ignorant in the way that you are.

     Explanation: Extreme weather happens when the climate is changing. That is because the heat balances change and the weather winds up with higher heat differentials to balance. Consequently the weather is more violent until a new heat equilibria is reached. It happens when climates are cooling. It happens when climates are warming. The key feature is that it happens when climates are changing. In fact extreme weather is the visible defining characteristic of changes in climate heat storage.

     Changes in climatic heat equilibria take centuries to reach. The reason for that is obvious – most of the heat (probably >90%) is moved using water currents in the oceans. That literally takes centuries for the deep cold currents formed at the poles.

     The majority of the current climate change input has happened in the last 50 years. Most of that has happened since the mid-1970s, which is why it was hard to measure. So comparing a record with hundreds of years with a recent but extreme shift is dumb and would only be done by a fool. I don’t have access to the paper myself because of a paywall. But I really don’t need to because I know that they are looking over centuries long records and I’m aware of climatic change timescales. It is called understanding the science – something that you are clearly too lazy to do.

     Based on past experience with you, I’m expecting that this comment will go from your eyes and out of your ears without meeting any grey matter.

       The weather related changes in north america were a phase inversion of the arctic oscillation.(from positive to negative) due to increases in stratospheric T.

         Yep. I’d expect these to keep shifting for quite some time.

         There is still a lot of discussion about exactly how fast the gulfstream pushes heat northward (and cold southward). It is a fast current with a seasonally max rate of 2.5 metres/sec at the surface and less further down the water columns out of the prevailing winds. It moves most of the the heat from the Caribbean to near the pole in about 40 years (from memory).

         I think what we are seeing now expressed in the Arctic sea ice and jetstream is probably heat transported from the Caribbean prior to the 80s. The rate of change in the Arctic should start increasing over the coming decades.

           Jets act as transport barriers as well.an enhanced polar vortex would limit poleward transport of energy. when they are migrating north we can see the effects as the jets act as transport blocks here decreasing flows from australia,and allowing advection (southerly flows) onto nz.

             Definitely still the case around Antarctica that blocking effects are still functioning. That won’t change much until some real heat starts penetrating into the inland ice sheets. A lot harder to do that in the Antarctica continent than it is in the Arctic ocean with a whacking great warm current pushing heat into it..

             There has been some pretty obvious leakage at the edges of the WAIS with the increasing speed of the breakups of the sea ice. And the EAIS has seen previously unseen measurable influxes of water vapour which has to be transporting heat inland.

             But fortunately unlike the Arctic the big heat transport south of the ocean currents gets caught in the barrier of the circum Antarctic currents. So it is getting the much smaller heat transports from the atmosphere.

             For the moment this seems to be keeping the fridge cold. Damn good thing. It’d make Invercargill a really cold place if it kept getting Auckland Island weather.

   Climate change – just have a look in our own back yard. The glaciers have retreated big time, and the snow caps are decreasing on the Southern Alps. Of course while Captain Happy is steering the ship, no one will pay any attention to the hazards approaching from all quarters. The thing is, he has his own “get out of jail card” – money, to last a life time, has everyone else? Probably not. That’s why he doesn’t care.

      The fact that it is a core tenet of the more extreme left and that reality has not reflected the scare tactics of the lunatic fringe like Gore, mean that even in the unlikely event that AGW is real, very few believe you.

    WA has a climate that has changed considerably over the past few decades.. and yes continual drought is very real here. I travelled on the bus the other day and the first topic of conversation with the passenger is “when is there going to be rain?” Why – because this is now a hugely dry country. The dams that were built several decades ago to provide water for the projected expanding population are dry – you drive past “lakes” upon which they now hold blowkart races. These were large expansive fresh water sites not so long ago.

    And you say there is no negative effect from global warming – its about time you looked beyond your own back yard Grumpy!

        You’ve just made a total idiot of yourself again grumpy.

        Right now I am in Ballarat – 150 km north of Melbourne and at an altitude of 450m above sea level and because of this it’s usually 4-5 degC cooler than Melbourne.

        It’s 6:29 pm – the temperature on the shady side of the house is 39 degC.

        People I am working here with who have been here all their lives cannot remember a month with two of these heatwaves in a row. The last one 10-15 days ago killed about 179 people.

        Australia always has had hot weather – but the evidence from simple, reliable weather station data is that these heatwaves, while they don’t necessarily break peak temperature records, but they are happening more often and lasting longer.

        So when you try and tell me it’s all bullshit – try asking someone who is living there right now.

          I’m living in Melbourne now. Generally I find people have very short memories when it comes to weather. We moan about wet summers but forget the stunner we had the year before. It’s why we all think there were golden days of summer in our childhoods. Actually I think that’s been documented by researchers.

      Hi Jon Yep I know that 5mm went a hell of a long way too! But there is a chance of a storm on thursday / friday! 🙂 Unfortunately Grumpy fails to realise that it’s just not increased temp that does the damage – nor just the increased periods of no rain. The higher temps mean the air can hold greater quantities of water vapour, and sucks even more moisture from the already parched ground, so any rain that does fall is very quickly absorbed. Grumpy might like to look at the rainfall histogram over the past few decades, for WA as well. There are step wise falls almost decade by decade. If he needed any evidence that Climate Change was upon us he only need to look at that.
      Increasing night time temps are of course the real kicker… and we have that in NZ as everywhere. And guess what Grumpy – that is the real evidence that it’s increasing CO2. Now go and do some real research on Global warming Grumpy and NOT at watts up who is nothing but a failed meteorologist

      “Anthony Watts studied Electrical Engineering and Meteorology at Purdue University, but has been unwilling to state whether he graduated

    These Australian heatwaves in the 40 degC plus range used to be a once in a generation thing. One of the worst was in 1908 that lasted over five days – but then the next bad one was in the 1950’s.

    Right now SA and VIC are having their second one this month.

    Right now Adelaide is over 45 degC and likely to hit 46-47 degC tomorrow.

    And it will get worse by the weekend.

      The definition of heatwave is three consecutive days above 35. Melbourne had two days just now, frankly not uncommon for this time of year. So, no, not a heatwave in Melbourne. As usual, a cool change has come through and temps will gradually rise again. Pretty standard, actually, if you actually lived here.

      Regardless, you’re falling into the weather-not-climate observational bias.

    Is this change caused by man’s impact on earth or by other factors!

    Alaska just isn’t what it used to be.

    The weather pattern favoring relentless cold in the Eastern states and prolonged warmth in the West will continue through the end of January.
    On multiple dates this month, temperatures have been warmer in Alaska than they have been in Texas, Louisiana and much of the Atlantic coast, including Florida.
    Nome, Alaska, which lies at 64.5 degrees north latitude has experienced at least seven days so far this month where temperatures have climbed above freezing. The normal high for Nome is 13 F.
