Obrigado André pela reportagem. Interessante a presença do Eng. Rui Moura, gostava de ter assistido. A resposta sobre as altas pressões foi exactamente o meu comentário aqui no forum ao artigo do Rui Moura onde ele abordava as altas pressões. Mas parabéns ao Rui Moura por ir à luta, adorava estar lá que tenho montes de dúvidas sobre a teoria dos AMP's de Marcel Leroux e se calhar até teria tido oportunidade de as ver esclarecidas à margem da palestra.
Quanto ao nitrato de carbono, pode ter sido alguma pequena confusão no meio de tanta coisa e tantos termos para registar. No contexto em que falaste disso, água dos oceanos e água da atmosfera, penso que ele terá falado do aumento do vapor de água. Noutro parte, talvez tenha referido do Óxido Nitroso N2O a par do Dióxido Carbono CO2 e do Metano CH4. O Óxido Nitroso apesar de ter uma concentração imensamente inferior na atmosfera que o CO2 e o Metano, tem proporcionalmente um efeito de estufa muito superior por unidade, cerca de 310x mais do que o equivalente do CO2, devido ao maior tempo de vida na atmosfera.
O Eng. Rui Moura e o site resistir.info (que eu aprecio muito por outras razões) estão sempre a justificar algumas as suas posições sobre AC invocando um tal Marcel Leroux. Eis o que diz um dos cientistas (podem ver o seu curriculo na coluna à esquerda) do RealClimate sobre o tal senhor:

Also re 65:
I have never heard of this Marcel Leroux before. The Praxis publisher’s web site claims he has published over 100 articles in international journals, but I looked over ALL the M. Leroux’s that Science Citation Index could find and these are the only articles that deal with climate or meteorology:
–
1. Leroux, M
El Nino
RECHERCHE, (310): 6-7 JUN 1998
2. Leroux, M
Climate models
RECHERCHE, (300): 7-7 JUL-AUG 1997
3. LEZINE, AM; LEROUX, M; TURON, JL; et al.
POLLEN TRANSPORT AND ATMOSPHERIC CIRCULATION OFF TROPICAL WEST-AFRICA DURING THE LAST DEGLACIATION

“Recherche” is the in-house newsletter of the CNRS (the French National Science Foundation), I believe. Global and Planetary Change is a very minor journal. This guy is no heavy-hitter so far as climate research goes. He’s at one of the more minor CNRS labs in France. Given the title of the book (i.e. anything that claims global warming may be a “myth” is bound to be scientifically unreliable) and the $129 cost (limiting its likely readership), I doubt we’ll be reviewing it anytime soon. The only mystery is why Praxis, which had the good judgement to publish Rasmus’ book on solar variability, would get taken in by something like this.
If you are looking to form your opinion and want something more quantitative than the books Gavin reviewed, the IPCC Third Assessment Report (WG-I) would be a much better place to start, as would David Archer’s book (Blackwell).
