Well, Ludwig, the two are joined at the hip.

You don't often hear the words "climate change" without encountering it's antidote "sustainability" in the next line or so.

Semantics.

good to see the religion is now privately funded. Its about time.

"Basically it is the economics, not the actual ability to supply the resource that is all-important".

Unfortunately if this is true then we are stuffed, because the value of the know fossil fuels reserves is in the hundred of trillions of dollars. Thus if the imperative is purely economic then we are bound to exploit it all, regardless of the consequences to future generations.

We know increasing CO2 levels will cause global temperatures to rise the only question is by how much, we also know that if we were to burn all the fossil fuel which can be economically extracted the impact on climate would be severe. This unfortunately is beyond any reasonable doubt.

Renewables can easily replace fossil fuels, but the change over is expensive, so it is only when current infrastructure wears out that is likely to be replaced with cleaner forms of energy production, and even then it due to the longevity of fossil fuel generators, a more likely result is that renewables will simply add to the amount of power being generated rather than replacing fossil fuels as the primary source of production.

In my view it is only when you accept that burning fossil fuels will negatively affect the climate can you really hope to come to grips with the problem.

<< Well, Ludwig, the two are joined at the hip. >>

They certainly ought to be, Poirot. But they ain’t always in some peoples’ thinking. In fact there seem to be a lot of greeny warmists out there who aren’t sustainabilityists!

These people advocate renewable energy, and greater efficiency and frugality, which is all good, but they miss the other huge factor – rapid population growth.

So there is plenty of concern about climate change without it necessary being holistic and properly sustainability-oriented.

I hope that our Professor Tim can see this and not continue to be silent about the population factor, on the global level and particularly the national level.

Professor Tim is but another exposed fraud feasting on the public purse.

What would you know?...about as much as the no-science shonks in govt.

(What's a "bum fight" anyway?)
