"Plimer's stated value of 4000 ppmv or greater is taken from Robert Berner's GEOCARB, a well-known geochemical model of ancient CO2. As the Ordovician was so long ago, there are huge uncertainties for that time period (according to the model, CO2 was between an incredible 2400 and 9000 ppmv.) Crucially, GEOCARB has a 10 million year timestep, leading Berner to explicitly advise against using his model to estimate Late Ordovician CO2 levels due its inability to account for short-term CO2 fluctuations. He noted that "exact values of CO2... should not be taken literally."

What about evidence for any of these short-term CO2 fluctuations? Recent research has uncovered evidence for lower ocean temperatures during the Ordovician than previously thought, creating ideal conditions for a huge spurt in marine biodiversity and correspondingly large drawdown of CO2 from the atmosphere through carbon burial in the ocean. A period of mountain-building was also underway (the so-called Taconic orogeny) increasing the amount of rock weathering taking place and subsequently lowering CO2 levels even further. The evidence is definitely there for a short-term disruption of the carbon cycle."


10 million years is not a short term fluctuation.

Ocean temperatures will be the average for the planet for the period of life, it will not fluctuate greatly because, as NASA has pointed out, the net effect of a water based planet is an average temperature which is controlled mainly by water evaporation leading to radiation absorbtion or emission.

Basically climate control on a planetary scale.

If there was a period of mountain building then volcanic activity would be higher and therefore climate gases would be higher - some cooling, some warming. But the net climate effects of the water cycle predominate.

The comments about "increasing the amount of rock weathering taking place" is quite frankly ludicrous. Even if this was the case there would be chance for many periods where the weather was far less and therefore the chance for a runaway scenario of warming would predominate. Your basically saying that the Earth has been lucky for about 500 millions years. Sorry but chance does not work this way.

If you take "weathering" in the modern context then there never has been a period of "weathering" as there has been in the modern era thanks to mining and farming. Just not credible.

There is no "CO2 predominates" ... CO2 is a minor gas of no great interest compared to many other gases.

The water cycle dominates everything.

If it didn't we simply and quite frankly would not exist.

So you say this is balanced ?

Have a read of your article ... is it scientific ?

Let's have a look ... does it mention ANYTHING about heat being reflected back into the troposphere from clouds ?

No, it doesn't. It's just a propaganda website putting forward ONLY an argument for increased heating via a "positive feedback loop". Sorry but that is just not correct, it's biased, factually incorrect and quite frankly FAKE.

https://earthobservatory.nasa.gov/Features/Clouds/

Anyway, here's the obvious bit about clouds ... obvious because if you have ever seen pictures from above the cloud they are bright like as though they are "REFLECTING" light and therefore heat.

"The study of clouds, where they occur, and their characteristics, play a key role in the understanding of climate change. Low, thick clouds primarily reflect solar radiation and cool the surface of the Earth. High, thin clouds primarily transmit incoming solar radiation; at the same time, they trap some of the outgoing infrared radiation emitted by the Earth and radiate it back downward, thereby warming the surface of the Earth. Whether a given cloud will heat or cool the surface depends on several factors, including the cloud's altitude, its size, and the make-up of the particles that form the cloud. The balance between the cooling and warming actions of clouds is very close although, overall, averaging the effects of all the clouds around the globe, cooling predominates."


I like this bit from the NASA article:

"The Earth's climate system constantly adjusts in a way that tends toward maintaining a balance between the energy that reaches the Earth from the sun and the energy that goes from Earth back out to space."

Which is pretty obvious, becaues if there was a feedback loop as your fake website suggests then the planet would have been cooked many times during all the natural disasters the Earth has been through.


Now why are clouds formed ? What is the reason clouds are formed ? What is the end result of a cloud ? They are created by water vapour leaving the surface, cooling and then falling back to the ground as rain. In essence what is the net effect of this operation ? To cool.

Clouds and rain/snow are cooling in operation. Energy is moving from the surface further up the atmospshere before being emitted back out into space as Thermal radiation.

Now I suggest you have a good long think how you have been conned into thinking in a totally unsceintific way. You don't need that fake wesbite to understand the environment around you.

we seem to have strayed a bit off topic but I did not say it was balanced I provided the link for balance and yes it is scientific.
The negative and positive feedback loops resulting from clouds is well known and is referred to in scientific literature and the current thinking is that the net effect is positive.
The link you quote is from 1999 and climate science has moved on since then.
I think anyone reading the Skeptical Science website with an open mind can make their own minds up and that is why I posted it.
I dont need to have a good long think about how I have been conned thankyou. My opinion clearly differs from yours but it doesnt really matter as neither of us are climate scientists although the ones I know are fairly certain of the conclusions from a wide range of research

The truth,

A l’en croire, il s’agit plutôt de favoriser un dialogue direct entre le président de la République et les Français. “… vous savez comme moi (…) que la présence de 50 journalistes, d’une dizaine de caméras, nuit un peu au dialogue direct et à l’échange que peut avoir le président de la République avec les Français. Donc il ne s’agit pas de contrôler, il ne s’agit pas d’imposer…”, a indiqué le porte-parole du gouvernement face à la presse.

Autre raison qu’a confié un conseiller du chef de l‘État français au magazine Marianne, c’est que ce dernier veut donner sa chance à chaque journaliste quelle que soit sa spécialité.

“L’idée est de permettre à plusieurs journalistes de chaque rédaction d’avoir un regard sur la présidence, au lieu de s’enfermer dans un tête-à-tête avec quelques journalistes politiques”, a-t-il expliqué.

Emmanuel Macron se rendra ce vendredi au Mali où il ira visiter les forces françaises Barkhane. Et selon la presse française, la nouvelle politique de communication de l‘Élysée prendra effet dès cette visite.
