When will the media stop showing pictures of power station cooling towers and chimneys of gas fired plants that are only emitting water vapour? Just sensationalism, it is not pollution!

Unfortunately, it looks as if Australia will be "looking to lead" once again as the Greens took over control of the Senate (Upper House) as from July 1. Now they can virtually dictate policy to the Labour government, which already relies on the support of independents in the lower house.
There is a growing awarenes in Australia that it might be best to wait and see what other larger emitters do before setting down legislation. But the governemnt is hell bent on introducing a carbon tax early this month and is negotiating a price per tonne with the Greens.

Richard - Australia. This has been an ongoing battle for nigh on thirty years. I managed to get one TV station to pull an advert about 25 years ago, as they were showing old footage from East Gemany as what was happening in Austalia.
Recently, I have written and telephoned tv news at least 20 times about the footage and stills they use during the carbon debate, all to no avail.

The solution to looming global warming? Easy. Reduce man-made emissions of carbon dioxide by cutting down on the use of fossil fuels - coal, petroleum and natural gas. Leave them in the ground.
The replacement? Renewables such as solar and windpower. If we phase in natural energy sources quickly enough, we may be able to avert catastrophic climate change.
Or so the story goes. But it is not quite so simple. As the proportion of renewable energy penetrating the electricity grid grows, the reduction of CO2 emissions drops sharply. By the time windpower (and, by analogy, solar) reaches about 20 per cent of the grid, the savings in CO2 emissions are negligible, of the order of a few percent.
The result seems counter-intuitive - surely the more renewable energy, the greater the reduction of CO2 emissions, and the less threat of global warming. But the reason for this finding can be found on the miles per gallon sticker on the windows of new cars.
The mileage for highway driving is always greater than that for city - stop and go - driving. When we touch the brake pedal, we change the engine speed. The lower mileage for city driving means less efficiency from the gasoline, and more pollution per mile driven.
In the same way, when back-up electricity (mostly natural gas power plants) - for the times the wind doesn't blow and the sun doesn't shine - is ramped up and down, there are more CO2 emissions compared to when the back-up is running full blast. Result - much of the emissions savings from using windpower or solar is lost.
Research results from Colorado, Texas, Germany, Ireland, Estonia and other countries bolstering the argument. If we are to save the world from the ravages of global warming, we will have to find an alternative to the programs advocated by many governments.

Every person with some minimum intelligence should know that CO2 (natural and man-made) is indispensable for all life on earth - CO2 producing oxygen through photosynthesis in plants on land and in water.
So people who still talk about "sequestering and burying CO2", are proof of an absolute absence of any intelligence at all. The idea to tax CO2 emissions is a swindlers dream. Who else but corrupt and/or mentally deficient politicians could design the "carbon caps and emissions trading" scheme ETS?
Simple analysis of the very small amount of CO2 emissions shows it is a non problem and that even if all countries closed every coal mine and power station, and stopped all cars, trucks, ships and aeroplanes, it would be impossible to detect any effect on world climate and temperature.
Man-made CO2 is a trace-gas and as such only 0,001152 per cent of the atmosphere and thus of no influence whatsoever on global climate or temperature. Climate on earth is principally influenced by the sun's activity and cosmic rays, while human behaviour is absolutely unable to influence the global climate; so no CO2 involved at all!
This utmost important conclusion has been demonstrated by the bright Danish scientist Prof. Henrik Svensmark and his team. For the good of abundant life on earth, it would be best to let CO2 escape from car exhausts and chimneys unabated.
Therefore, cars and other products that are promoted as "low on CO2 emissions" are obviously in principle not helpful for abundant green nature, although the infinitely small amount concerning manmade CO2 will not affect nature at all; not in a positive sense, nor in a negative sense as explained before.
But it shows plain ignorance to advertise products with "low on CO2 emissions", which ignorance is wholly due to the 30 year long indoctrination with the AGW CO2 lies of the AGW protagonists/alarmists.
