Dunno about that TC. "Global warming" climate models have always (that I can remember and this is going back a lot of years...) predicted colder weather in the UK / northern Europe as a result of a slowing Gulf Stream / North Atlantic Drift, which is the only reason they are as warm as they...

Sorry mate but that term was flying around about 15 years ago if I recall correctly... pretty much around the time the Greens (the political party) came to prominence as it describes them perfectly. Doesn't make it any less true of course. A group of people I have very little time for...

Actually, the theory goes that the risk is that global warming might stop or slow the North Atlantic Drift ocean current which keeps Europe (and with the Gulf Stream the east coast of the US) much warmer than it otherwise should be for its latitude. So, if anything, this event could well be...

Hi Bill We are talking at cross purposes. You are referring to sea ice and I am talking about the "overall" combination of both land and sea ice. The AAD page that OO linked to explains the points quite well - worth a read. Either way, I should probably repeat again that water balance...

I thought that was our point of difference. You wouldn't need $40/tonne to: - Turn off 55% water content Latrobe valley (and the rest) coal (peat) power and replace it with high efficiency (60% instead of a tick over 30%) combined cycle gas power using our abundant coal seam methane...

My points: - Sea level rise is not the point. It's only one of a million climate variables that can impact our quality of life. Focussing on it takes away from the complexity and reality of the thing we are trying to assess. - Yes, highland snow fall in areas that stay below freezing takes...

I agree. The Gulf of Mexico and the Pilbara region of WA share the record for the highest frequency of hurricanes / cyclones in the world. One is much better placed to deal with it though... A hurricane in the Gulf of Mexico is not news and people do the science a disservice when they jump...

It's winter?

Hi TC You have summarised the issues as well as I could have. The points I would make on this are: - All other things being equal (they never are but humour me here...), the addition of artificial N (& the P & K) works by accelerating the decomposition of organic carbon/s and other...

Yes but what would they know? They're just part of the "system", intent on their socialist redistribution of wealth through fudging Antarctic thermometer readings... And those reductions in land and sea ice are just benign and to prove it I'm willing to bet my children's future on me being...

I agree. The track record in these things is not good... and the form of the proposed CPRS does nothing to inspire confidence in this area. Also a pity that Labor couldn't resist the temptation to turn this into an income redistribution exercise. It probably would have got through otherwise...

Both "Global Warming Swindle" and "An Inconvenient Truth" are sensational, alarmist, populist mockumentaries that are long on hyperbolae and short on facts. We can do without the likes of both of these programs as they just as likely to result in the focus being removed from the risks that...

Which real data set would you like? The record of US surface temperatures? Australian? European? Chinese? What about sea temperatures? Over what time period would you like that? 10 years, 100 years, 1000 years, 100 million years? Along with records of CO2 concentrations, sea levels...

That's a pity because modern common rail diesel engines are much more efficient than petrol engines due to the greater energy content of their source fuel (more long chain hydrocarbons). Natural gas is a relatively inefficient fuel due to its lower energy density. Basic rule of thumb is the...

While we're picking on poor Witzl I would like to point out that many of the places I go to are completely inaccessible to Falcodores. Our Prado with recovery gear works great by comparison and the kids love camping. My farming in-laws would also put a fair bit of value in having a decent 4WD...

Maybe we should be part of the solution instead of part of the problem if we would like other, much less wealthy, countries to do the same. The cost to do so is pretty small after all.

And people would respond by using less of the stuff. I don't buy the "energy demand is inelastic" argument. When you get pressure on your cost base you take a look at it to see what can be done about it. The fact that electricity costs will rise from here (with or without an ETS) will see...

Hi Witzl Examples of this are rife throughout the country. To give another one, ten years ago I put up a business case in a utility to change a 3MW boiler feedwater pump in a power station from the thirty year old direct on-line mechanically throttled control to a modern variable speed...

Witzl the Libs are supposed to believe in the free market yet you are advocating a "government knows best" approach to energy policy rather than putting a price on carbon and letting the market decide. Good luck with that one on the conservative side of politics. A new tax on energy! That...

And so the Coalition declares itself unelectable for another couple of terms. They have indeed learnt nothing from 2007. If they had advanced a sensible alternative to the ETS they might have my sympathy. As it is they are just obviously overrun by conservative dinosaurs who stand for...
