The new Labor Government has discovered in Bali this week that John Howard has left him a huge greenhouse debt.
Over 11 years, the Howard Government allowed Australia’s greenhouse gas emissions to grow so profligately that the task of cutting them back and meeting international expectations appears almost impossible. The Howard Government was allowed to mask the extraordinary growth in fossil emissions by offsetting them against the sharp fall in emissions from land-clearing. So in 2005 our overall emissions were only 4% or so above 1990 levels, even though our emissions from burning fossil fuels had grown by over 30%. Any future cuts now must come from coal, oil and gas. The pressure on Australia is enormous, but Kevin Rudd is trapped. Australia’s total emissions will reach around 110% of 1990 levels in 2010, which means that a 25% cut below 1990 levels would require Australia to cut its emissions by a third over a 10 year period. The deal granted to Australia at Kyoto in 1997 was so generous that we could easily have come in under our target for the 2008-2012 period and been left with a swag of emission credits we could then have banked for the second commitment period. But Howard refused to sign up then and now the opportunity is long gone. It will take the Rudd Government many years to pay off John Howard’s massive greenhouse debt. In truth, the Australian public will pay for it. The economic modellers have been pointing out for a long time that delaying action drives up the cst of cutting our emissions. Although it is now Rudd’s problem, it is Howard himself who must take all of the blame, for it was his personal decision, against all of the advice, to remain stubbornly opposed to accepting the reality of global warming. |

EC, really good post. The task of a one third reduction over ten years is tough. It will take a "war-effort" to achieve.
However, it is this that I wish to take issue with: In truth, the whole of humanity will try to pay for its own pollution - and it will fail. We cannot even pay the interest bill. In short we should forget about trying to avoid global warming because it cannot be prevented. Why? We are past the point of no return. We will go >5 C by 2100 and on the way suffer mass starvation and all-out world wide resource wars. We are phkd. The first world has the science/technology to survive as long as it can resist hungry invaders until they starve to death. However, I wonder if we have the political courage to cut 80% of the world out of any future. So, the aim of joining any carbon treaty is to ensure we remain part of the winning side. If we shirk our load, the likely winners might not want to have us in their group.

Thanks! I think your gloom and doom predictions are a bit premature though, and you underestimate the possibility that new techn ologies could help curb the current discharge of greeen house gas emissions into the air. I still think the Australian public will have to pay higher taxes and in other ways to afford Australia's new found committment to prevent global warming.

Predictions are by their nature, premature.

I think you with 99.999% of the punters do not have either 1. the knowledge or 2. the skill To know what the scientists are trying to tell the public. The public are being given the middle road version - middle as in between the optimist an pessimist version. The reality is that the models are not generally factoring in the "feed forward" effects because the non-linearities in the maths cause huge uncertainty values - uncertainties that make the estimates unusable. However, the climate scientist community is shit scared. If you look at most predictions from a decade ago for today's conditions (temp, glaciers, ocean pH, et cetera), you will see that they were under estimated. It is a case of exponential increases in response to geometric input. I am not by nature a pessimist, so, I am worried that this is something that worries me.

Good effort Blank Frank, and a very insightful well thought out post in my opinion!

The most common drive behind this passive attitude of the developing world is due to overwhelming problems of poverty, hunger, illiteracy and disease that the major parts of the third world countries have been struck down by these emerging threats. It is here that they are giving secondary consideration to this problem of global warming.

The organism Homo sapien is something pretty bloody special. It is the first time and may be the last time on Earth, that a mutation in the neural system of animal has produced runaway exteligence. It has resulted in organism which is the ultimate trophic generalist. WOW! That's what I say every day I watch and witness the difference between natural ecosystems and cities. We are so very special, it is no wonder that so many of us invented a god to thank every day.

Can it be that earth warms up and cools off without human's help? It's called "climate" and it changes from time to time. Doesn't mean we did it. Doesn't mean we can stop it. Maybe we're just along for the ride? |

It dosen't really matter whether Global Warming is real or not, or whether humans are at fault here. The thing that matters is the initiatives people are taking towards Global Warming which are highly beneficial to humankind and the planet. Just because Global Warming or is isn't true dosen't mean we can simply pollute to our heart's content or squander the Earth's resources. We're going to run out of fossil fuels one day, and by then alternative energy sources will have to be adopted anyway. But why wait until then? The sooner we start making this transition from fossil fuels to alternative energy sources the better.

I totally agree with your sentiments. It seems that we spend way to much time on blaming who's causing the CO2 effects rather than solving the problem of how to cope with the increased CO2. Now some environmentalists may say that reducing human's CO2 footprint will solve the problem. That is not necessarily true. We still have to deal with the nature's side. I think the focus should be more concentrated on how to cope with the nature's responses to the increased CO2 levels so humanity and mankind civilisation can thrive and be in a beneficial embrace with nature.

But these a not reasons to reduce carbon emissions and in doing so you are increasing the economic burdens (disproportionately) on high population low resource nations which will lead to great differentials between the first and third worlds which is just a recipe for disaster (ie conflict).

When small changes of a parameter leads to big changes in final predictions you generally have a problem because you might not know your initial conditions that accurately and also your model probably involves a number of assumptions of simplifications which are at least of the same order of magnitude as the change in initial parameter values which leads to the divergent results. In modelling jargon, you're up shit creek.
I think there are a lot of people in the climate modelling community who believe too strongly in their models. In 1990, one of my favourite scence popularisers John L Casti wrote a book called Searching for Certainty. Chapter Two deals with the question of whether we can predict changes in the weather and climate. While things have no doubt advanced somewhat ni the past 17 years (at the very least in terms of computing power) the conclusion of that work was climate modelling was lagging a far way behind weather forecasting and should not be used to predict anything more than a couple of years into the future. Predictions in the order of decades would just be speculation. I haven't seen a lot to indicate that this limitation has been adequately overcome. |
