Quote:Have you ever heard of Le Chatelier's Principle? It's more commonly applied to chemical reactions, but in many real-life situations, reactions and effects are reversible. The Global Temperature / atmospheric CO2 relationship is such an equilibrium situation. Increase the CO2, the temperature rises, but increase the temperature (for example by increases in solar irradiance, and CO2 is released from the Oceans, increasing the atmospheric concentration.
Muso, this is post-modern, activist science journalism. Unwittingly, you are undermining your own case in the rush to be seen as as knowledgable. That kind of rerversability of cause and effect, if applied to warming, would mean that the increased CO2 is not
due to human activity. So going with Chatelier's Priniple, you would have to revise the A in AGW.
But then we would have a completely different issue and the question would be: how to respond to natural climate change? I would hazard a guess that the existing shake-down principles would continue to apply but at least humanity would not be fingered as the casue
You display a total ignorance of equilibria. They were teaching Le Chatelier's Principle since at least 1920. They were certainly teaching it in the 1970's when I did my first degree.
There is a natural equilibrium, but superimposed on that is the addition of about 8000 Gigatonnes of CO2 into the atmosphere every year. That is not an insignificant amount. The effect of that has been to shift the natural equilibrium.
And when was the climate in 'natural equilibrium'?
More importantly, you came up with the Chatelier bizo to show how cause and effect can be interchanged to explain away the hoistorical sequence of warming followed by increased CO2.
Applying equilibrium principles to the climate, it would mean that even though in the past Gaia increased her CO2 output in response to warming, now she is increasing her temperature in response to CO2. For the first time
ever.
You are saying that by way of Chatelier's Principles of chemical equilibrium, since 1920, the after-effect of previous warmings (CO2) can become the cause of warming. At last, a 'retrospective cause'.
Because as every schoolboy knows, it's really a balance of warming and CO2 when you sit on the climate see-saw, it's only these two things that need to be in the equation. One way or another, it's
gotta be that 8000 gigatonnes of CO2. That's an awful lot of lollies, even if it only means less than 0.05% of the total atmospheric gases.
