The Earth is not a perfect black body.
There is thus no such thing as global warming in our Biosphere. The Biosphere is a quasi closed thermodynamic system that is continually pumped away from any possibility of a global warming thermal equilibrium with solar, geothermal and cosmological energy. Our biosphere is COMPLEX enough to reradiate excess heat to space and into biomass in a variety of ways that scientists have yet to fully understand. Greenhouse gases are incidental to these processes.

Climate change is real and is a direct result of global sea change tendencies of human populations along with supporting agriculture, industry and mining operations. 25% of the Australian population is slated to be in the small coastal strip from Brisbane to Coffs Harbour by 2020 for example. The attendant wastewater interference in excess global energy fluxes on their way to polar regions is the major cause of increased storms and droughts that we know as climate change. When that excess energy reaches the poles, it is reradiated to space via super cooled macromolecular energy transformations that are totally oblivious to any greenhouse gas interception. The ice caps will always be in darkness for most of the year, will always produce ice by supercooled macromolecular transformations and will thus necessarily radiate heat to space no matter how much greenhouse gas is in the atmosphere. Heat trapped in circumpolar air and ocean currents will modify polar ice distributions ONLY at a REGIONAL level around the poles. The time dependent profile of these modifications will be COMPLEX but only a fool would mistake it for a true GLOBAL scale phenomena with the weak data sets available today. Only cosmological events that might cause a reorientaion of EARTH's axis are capable of melting ice caps. Even then, the addition of cosmic energy will only pump the biosphere to higher levels of order over a sufficient time period.

If PD really wishes to globally warm our biosphere. If he MUST. Then all he would have to do is bunk planet Earth out to the vicinity of Mars orbit.

That would do nicely.

And BTW,

even if H5N1 mutates to a human infectious format, it will not cause a pandemic. Global thermodynamics are wrong for this. After WWI it was a cinch for spanish-flu, but not now. Maybe if Peak oil wars in 20 years time wipe out a few billion people, the world will be thermodynamically susceptible.

And speaking of learning science I wonder if PD wants us to know the complex regimens required to keep viruses alive in the lab. These regimens actually mimic the thermodynamic disorder that would be caused by wars and overcrowding in human societies.
Without a proper level of disorder, primitive lifeforms like viruses do no function well at all.

"Y2K was not a conspiracy but it was most certainly backed by a strong majority consensus of experts."

This is a totally falacious analogy. It assumes that no action was taken over Y2K, and that it was never a real problem. It might have been overhyped in the media (like everything), but a combination of active steps in the computer industry and a very high rate of turn-over of new techhnology in the late 1990s meant that the crisis didn't eventuate. But if no-one had done anything, then it would have been a problem. The lesson with Y2K is that sensible, measured action is both necessary and possible over Global Warming.

Another comparison is ozone depletion, which has been halted, if not yet reversed, by a combination of technology, legislation and international agreements. Why is this so hard to accept among GW deniers?

Really, Mhar. If the Y2K problem was mostly fixed before the event then, surely, somewhere in an isolated nook there would have been someone still making do with his original IBM PC circa 1991. And if Y2K was a real problem then this would have failed. Can anyone out there advise of any instance where a system failed on 1/1/2000? I doubt it. Nice try though. Repeat it often enough and someone will believe you.

60 Canadian scientists recently wrote to their PM highlighting their concerns about the policy process taking greenhouse assumptions as fact. Our own Prof. Ian Castles has quite a bit to say about the flawed modelling of the IPCC and their reluctance to deliver full transparency and substantiation to their deliberations. Just google him.

I will give you one word that will almost fix global warming,
TREES! How many trees has the human race cleared? billions and billions. Why do they call it rain forest? because it creates rain.
When will mankind realize we have been given everthing but we look after nothing. Now we also have Howards IR laws to worry about.
This Liberal PM is a serial lyer but 60% of you people voted for him what were you thinking?

Democracy is the first issue. Without it we can't even have a discussion of any real consequence. The Labor Party is the only Party in a position to effectively address holistic issues of democracy, sustainability and hope. As we all know, the ALP is floundering, betwixt an inaccessible past and a much wider future. If you're serious about making a difference, join the Labor Party. Fix the process so we can then collectively fix the world. C U there ... Q
