looking at your reply I can see that you realise that your argument is in trouble.

Soren,  Let me put it in diagram form for you. That's the Greenhouse effect in a nutshell. Do you see anything about generated energy there? No. Generated energy is irrelevant because it's less than Solar energy by a factor of about 200. (edit - that figure is wrong. I'll recalculate it some time, but it doesn't alter the fact that heat from energy generation is insignificant in the scheme of things)

The Greenhouse effect basically reroutes some of the solar energy so that less of it is re-radiated back to space. Understand that basic fact and you'll understand the initial post in this thread.

NB - You do not need a Geology professorship to understand that very basic principle.

Understand all that.

But cop this: "The Greenhouse effect basically reroutes some of the solar energy" - that means you have to have some solar energy to reroute, to start with. No solar energy, means nothing to be trapped by the greenhouse gases. So far, so good.

Now, all those denialist coves banging on about the sun are saying that there has been increased solar activity because of sun spots or whatnot. More solar energy to reroute. More oming in, more getting trapped, blanket being the same.
You follow?

So complexity is the argument, not the sun or the moon, or mah baby's shapely arse. The sceptics, denialists, evil horsemen of the apocalypse - call them what you like -  are revolting NOT againt science, not against reason but againt simplistic reductionism. Against reductionism in the name of science.

Good! You are finally starting to understand. If the Solar energy is reduced for some reason then the heating effect reduces as well. So far so good.

Now it comes down to a discussion of what the Sun has actually been doing for the last 50 years.

There are a large number of people actually studying the Sun and Solar output, and they have been studying it for many years.

If you want the best measurement of Solar Input, the best place to measure that is outside the atmosphere - right?

If we can show that for the last 50 years (the bulk of the warming trend observed since 1850) that the temperature trend is positive, yet the Solar output was relatively flat, do you think that might just ring some alarm bells? I've posted this graph before. Before I start to explain how these measurements are derived, just look at the Solar  irradiance since about 1975, then look at what temperatures have done.

Let's keep it simple for the moment, then I'll talk about Solar activity (related to Sunspot numbers). That correlates quite well with temperature too, up until about 50 years ago.

Soren,

If it suddenly clicks at any time that you were wrong, don't worry about it. Smarter people than you have been taken in by the nonsense that's written in the blogosphere.  When it comes to this particular issue, there are no winners. Only losers.

Again, this is not a political issue. Even if your leanings are Right Wing,  that's an even better reason to think this issue out as an individual and not one of the 'comrades'.

Much as I hate to quote Sir Joh, democracy comes down to 'feeding the chooks'. In most cases that amounts to feeding their suspicions and prejudices (carefully).  Most people do not understand the real issues and just revert to Football-like allegiances where they call the opposite side 'Leftards' or 'Thatcherites' and they repeat their own side's mantras parrot fashion.

To take another analogy, if you can steer the flock into the pen by getting dogs to bark at the right time,  then you can engineer the desired result.  The sheep think they have a say in it, but they really don't, and if they did, the station would go to ruin.

That was probably a summary of what many people know but no politician is game to utter.

This whole 'issue' is more slippery than eels on skates. First it was global cooling, then global warming, then antropogenic global warming, then climate change, now it's climate justice!

http://blogs.news.com.au/dailytelegraph/timblair/index.php/dailytelegraph/commen...

And anyone not buying it is a denialist, an idiot, a fascist, a naive drone, etc, etc. Well, I am not signing up to whatever this guy, for example, is pushing. Or the rest of the propagandists.

I think it's a farce.

Re sun graph - reconstructed solar irradiance? Now modelling some other variant is proof?

These graphs are from blogs, warmerist blogs. Being condescending about blogs that don't buy the whole idea of man made climate change/warming/justice is part and parcel of the 'scientific' argument mounted. the whole issue is NOT about science but politicised science. It is not impartial, it is about vested interests, prestige, vanity, political convictions, resistance and attack.


For my part, the weather is so complex, and CO2 is so miniscule in the atmosphere (itself just one of the variants in climate) that any unblinking declaration to camera, like the above clip, makes me think that believing in 'climate justice' IS the domain of lunatics.

And I am not calling you a looney, Muso, but the science is a long way off from being conclusive. Slicing and dicing CO2 measurements to death is not a scientific conclusion about the weather. Plotting them against some other guesswork about some other climate element is not conclusive either.

I mean, can anyone claim that there is a scientific consensus on what all the global and galactic influences on climate are and what their  respective importance is, and what the mechanism is for all their local and global interactions over time? Of course not. It is lunacy to pretend that there is an understanding of how it works, let alone to predict not only how it will turn out, but that we can influence it by simply reducing the emission of our precious bodily fluids, er, I mean CO2. To pin it all on CO2 is hubristic lunacy (and that's the benevolent madness).  The only point of it is to drive political action. By loonies.
The non-blinking 'climate justice' militants show just what a dangerous nonsense it all is.

Slippery is crawling away from an argument when you think you'll be confronted with the truth. We were talking about Solar output?

So let's take a look at what the measurements (not reconstructions) actually say. We have a pretty good set of Solar irradiance measurements from satellite measurements.

And by the way - thanks for the fish.

Let's take a look at the data we have available.  Anybody can throw their hands in the air and say "It's all too difficult", but let's see what the data actually shows.

We have pretty reliable satellite data from about 1975. The world authorities for Solar irradiance are the Physikalisch-Meteorologisches Observatorium Davos" (PMOD). If you look on their website, they are based in a very picturesque part of Switzerland.

The graph shows Solar Irradiance. It's measured directly by a number of satellites over that period. Solar irradiance is a measure of how the Solar output has varied. There are few interferences, unlike measurements taken at ground level. It's a good measure of what is being presented to the Earth.

Notice the peaks? If you look at the scale, it's not that significant. It varies about 2-3 Watts per square metre peak to peak over approximately 11 year solar cycles.

The main thing is that there is no actual increasing trend here.  This is during a period where there was a very pronounced warming trend.

OK, hold that thought, because we're not done yet.

Ok, If we want to go back in time before the satellite data was available, the data is not as accurate, but it's not totally worthless either. We can determine Solar output from the cosmogenic isotopes produced during periods of high solar flux. Notably Beryllium 10 is used as a proxy.

And hey, when we plot a graph of temperature (Deuterium proxy and others) against Solar output, we find that generally, there is a good correlation between solar output and temperature.

Let's take a look at the graph. It's the sun! you say. Well it is to some extent. Notice the crossover around 10,000 years before present? Obviously something else is going on there (Milankovich effects - obliquity , tilt etc)

Ah but look at the slope near the present. Doesn't that show increased solar activity leading up to the present day?

On the face of it, yes, but let's take a look at the recent detail.

I should tell you where all this data is coming from. It's mainly work by the Planck Institute, as in Max - not thick as (Sorry about the Irish joke )

You might recall us talking about Sami Solanki? He's the Director for the Sun-Heliosphere Department of the Max Planck Institute for Solar System Research.

He has been quoted as saying:

Quote:
The sun has been at its strongest over the past 60 years and may now be affecting global temperatures... the brighter sun and higher levels of so-called "greenhouse gases" both contributed to the change in the Earth's temperature, but it was impossible to say which had the greater impact.


If you look at the previous graph, you can see how that is true. If you look at the graph below, you can see clearly how Sunspot numbers  peaked around 1955 or so with another small peak around 1982, but since about 1982, it has been following a downward trend. (notice the thick yellow line?)

Also plotted on that graph is the CO2 concentration in the atmosphere.

That is relevant because while sunspot numbers have been decreasing, the global temperatures have been rising.

Again from Sami Solanki:

Quote:
according to our latest knowledge on the variations of the solar magnetic field, the significant increase in the Earth’s temperature since 1980 is indeed to be ascribed to the greenhouse effect caused by carbon dioxide


If anybody in the world is acquainted with what the sun is doing, it's Sami Solanki.

(That's not the core argument, but it's the easiest one to relate in non technical terms. )

Before about 1970, it wasn't really clear that Greenhouse gases were resulting in an increase in temperature.  The Greenhouse gas signature was in the noise of natural effects such as volcanic eruptions,  ENSO and Solar variation.

While it was certainly predicted that greenhouse gases would result in global warming long before, it was only in the 1980's that a clear warming signal was observed that could not be attributed to other effects.

LOL - By the way, you can do a cut and paste audit on any of my posts. I type them in - I don't usually cut and paste, except sometimes from my own posts elsewhere in the vast blogosphere.

So you are saying that


1. the causal relation between CO2 measurements and temperature measurements has been established. 
2. the absence of causal relationship between solar output measurements and temperature measuremnts has also been established.
3. therefore, having established the causal relationship of 1. above, reduction in the human component of CO2 measurements will reduce, halt or reverse (depending on the reduction) the temperature measurements over a knowable period of time.



My position is that none of these causal relationhips have been established and are unlikely to be within our ken to be established for a very very long time to come with the kind of accuracy assumed under 3. above.



Your take?
