Prof. Dr. Vincent Courtillot Präsentation

[SiriusTexra]

Wow, being a climate change believer (that sounds kind of stupid now) this is actually shaking me quite violently...

I guess...when I think about it I have sort of just accepted whatever I heard..in my defense the people I hang around all said/say it's true..

I've always wondered if there was smoke to this fire. This is the only "science" that is this split within the scientific community. That in itself and learning that other institutions are withholding information kind of worries me.

[hengistmcstone]

At 6:20 "There is no such thing as world climate. A Priori there might be but it's not at all obvious"

So is there or isn't there?

[aletoledo1]

@hengistmcstone all weather is local. Does it really make sense if you averaged temperatures across a continent? One end might be a desert and the other in the arctic circle, so the patterns of weather are unique to those regions and not the political borders.

[arscill1]

It's time to put AGW into a bigger perspective. Add the Bush administration's support of AWG and then the effects of that... means to hold back development in Asia and Africa with environmental arguments... Any questions of why this situation is as it is?

[Bzakey3]

Golden, I hope a lot of people see this.

[coturnix19]

wish he is wrong... wish temperatures returned back where they were in mid-miocene.... neraly tropical climate in continental europe is good. hate snow, hate winter.

[juergens48]

This is good science. Shocking as he's telling that younger scientists or students cannot work in such project, unless damaging their carriers. Green inquisition?

[cthulhu11111111]

btw my questions are rhetorical, but in case anyone wonders, there is no good correlation between cosmic ray count and global temperatures. Cosmic rays are flat in the past 50 years (along with other solar activity variables) while global temperature goes up.

Hence why such graphs are never shown in presentations like these

[cthulhu11111111]

I question the graphs at 17:07. They are correlations not between solar activity adn mean temperature, but between solar activity and "annual quadratic variation (or lifetime) of temperature"

Why such an odd unit? And more importantly - what do the mean temperature vs solar activity graphs look like and why aren't they shown?

Additionally why are the graphs of Europe and Holland and not of the globe? The Earth has warmed in the past 30 years. It would be nice to see a comparison of that.

[tylerdehate]

@cthulhu11111111 did you not listen to the point earlier in his presentation where he pointed out that he does not think that a World Climate can be shown to exist.

[cthulhu11111111]

@tylerdehate

So there's no such thing as ice ages? Ie an age where the Earth has a colder climate? I kind of see his point as global climate is not a thing where people exists. But it is a useful statistic to use to measure climate warming or cooling.

[laurelbush]

very interesting, if only my French was as good as his English, or even my English as good as his.

[clifferny1]

Ah, one of the prominent member of "Les Chevaliers de l'Ordre de la Terre Plate" hard at work.

Same presentation he is doing since 2009.

@clifferny1

After that beautiful lecture, all you can come up with is a ridiculous claim unsupported by any evidence? Who is in the wrong, the man who can come up with a coherent 30-minute argument, or the man who can't think of anything wrong with it but to say the lecturer must be a flat-earthist? So where is that hotspot? Where is the empirical evidence? Where is the decline (oh, and the sudden jump too; they hid that as well)? Where is the MWP? Where is the Roman optimum?

[cthulhu11111111]

@randomxnp

"So where is that hotspot?"

Ah but didn't you watch this video? Courtillot says there is so much uncertainty in the data. Why would you expect to be able to find a hotspot if the data is so uncertain we can't see it?

[dila813]

@randomxnp He doesn't have evidence, he admitted it. At least his theory can be proven false unlike the IPCC Theory which can't. He is in the process of gathering proof.

[jonohx]

@clifferny1

Same old political denial from a fully paid-up member of the WI (Watermelons International), eh? Ostrich, head, sand.

[randomxnp]

Superb. Reminds me of the best lecturers I had studying natural sciences at Cambridge.

[Sueezedtight]

The only thing that is settled about climate science is that the IPCC has settled on an agenda and it encourages contributors to "toe-the-line" so that a "consensus" is achieved. Prior to climategate, there was also a settling of accounts with any scientist that tried to refute or even check the work of the cadre of climatologists that promoted the CAGW line. Their unscientific approach was exposed and the hard work of a few good people has removed the scales from our eyes. We thank them greatly

[JimmyGris]

That is science in progress. Bravo! (Ceci est la science qui se fait. Bravo!)

[TheTempestSpark]

Amazing!
