Un árbol, procesa CO2 durante los 20 primeros años de su vida (20 ó 15 ó 25). No más.
Tras este período, mantiene un proceso equitativo. Suelta una proporción semejante a lo que "consume".
De hecho, recientemente, se inició una investigación, para tratar de descubrir si el Amazonas, reduce el CO2 o... ¡¡LO AUMENTA!! Pues sus árboles son antiquísimos.
Al morir el árbol, expulsa, cerca de un 99% del CO2 que ha absorvido durante su vida... pues sus tejidos están formados por él (CO2).
Es decir, que un árbol, PRODUCE más CO2 del que consume.
Nicolas, ¿hiciste la primaria? Los árboles hacen un ciclo de 24 horas: de día absorben CO2 y expulsan O2, y de noche vice versa, y cuando mueren, expulsan todo lo que absorbieron. Da igual al final.
El «climategate» empieza a morir
Saltó la noticia a finales del año pasado: alguien consiguió llevarse una gran cantidad de e-mails privados de los servidores de la Unidad de Investigación Climática (CRU – Climate Research Unit) de la Universidad de East Anglia. Entre esos mensajes, aparecían discusiones en las que los científicos parecían manipular los datos con el propósito de hacerlos concordar con las peores predicciones. En Real Climate aparece un resumen bastante exacto de los hechos; también es muy recomendable este artículo en Climate Progress. Si quieren un poco de paranoia borderline, entonces preferirán esta otra recopiliación de noticias en Libertad Digital.
Poco tiempo después, el Comité de Ciencia y Tecnología británico comenzó una investigación de los hechos para ver qué se podía concluir de este episodio. La conclusión se publicó ayer. Sorpresa:
The focus on Professor Jones and CRU has been largely misplaced. On the accusations relating to Professor Jones’s refusal to share raw data and computer codes, the Committee considers that his actions were in line with common practice in the climate science community but that those practices need to change.
On the much cited phrases in the leaked e-mails—”trick” and “hiding the decline”—the Committee considers that they were colloquial terms used in private e-mails and the balance of evidence is that they were not part of a systematic attempt to mislead.
Insofar as the Committee was able to consider accusations of dishonesty against CRU, the Committee considers that there is no case to answer.
The Committee found no reason in this inquiry to challenge the scientific consensus as expressed by Professor Beddington, the Government Chief Scientific Adviser, that “global warming is happening [and] that it is induced by human activity”. But this was not an inquiry into the science produced by CRU and it will be for the Scientific Appraisal Panel, announced by the University on 22 March, to determine whether the work of CRU has been soundly built.
En otras palabras:
1. No es del todo inusual resistirse a compartir los datos en crudo y el código informático, pero eso debería cambiar. Y estoy de acuerdo. Al hilo de esto, debo enlazar este artículo en el Guardian: If you’re going to do good science, release the computer code too.
2. Los términos sobre los que los negacionistas se rasgaban las vestiduras no son más que palabras sacadas del contexto coloquial en el que se encontraban.
3. No ha habido malas prácticas.
4. No se ha encontrado razón para decir que no hay consenso sobre el cambio climático.
5. En lo que respecta a la calidad de las investigaciones producidas en el CRU, habrá otro informe posterior.
Pero no se preocupen: el negacionismo nunca descansa. Tampoco se para a leer, ni espera que los receptores de su mensaje lo hagan.
French climate skeptic caught cheating
By: Bjørn Willum
04.04.2010 10:30 | World France's most prominent climate skeptic Claude Allegre has been caught messing about in a new bestseller, which he tries to show that the greenhouse problem is fabrication.
PARIS: France's most famous climate change skeptic, former education and research minister Claude Allegre, were caught with pants down in the rigging around the data into a new bestseller.
In the book 'Climate Fraud', which since the release in February has sold 120,000 copies, claiming Alegre that there is no correlation between temperature increases and CO2 emissions.
In support of its claim reflects his in the book a graph of the Swedish climate scientist Håkan Grude, allegedly shows that the temperature since 1900 has not increased as much as it is generally assumed, and - what is even more interesting - the temperature curve is expected to ' break 'in the coming year and decline significantly toward 2100.
Unfortunately for Alegre was a journalist from the online newspaper Rue89.com the idea to scan the graph and send it to Sweden where Grude laid it on top of its original chart, published in a scientific publication from 2008. The conclusion was striking: Allegre had simply redrawn the graph between 1900 and 2000 - and also continue the line after årtusindskiftetb where Swedish's data stopped.
Threats of violence
'All the graphs in the book are re-fit. So there are inaccuracies or exaggerations even in comparison to the originals. It was an editorial choice, "admits Alegre, although not much to be gone in the beds.
"You can not predict weather and climate models is a big deception," said Allegre example, in an interview with the Danish TV program DR2 Expatriation to the Earth Summit in Copenhagen, where he is on the journalist's remark that he himself was accused of messing about responded that his critics could have no head.
Allegre also believe that there is no reason to pull the country now because of the rigged graphs. "This is the text that counts," said Allegre in a debate on radio station France Inter other day and was furious when the other participant protested: "There was warmer during the Middle Ages," he shouted and pounded the table, while the presenter had to summon all his authority to prevent a further argument for open mic.
Self support
More than 400 climate scientists wrote an open protest letter to the current teaching and research minister Valerie Pécresse to ask for support because of the accusations that constantly rain down upon them from the 73-year-old Alegre. Researchers want a "public confidence in our integrity and our work."
"Many of us thought it was wise not to respond. But it has assumed enormous proportions. Allegre accuse us of being a mafia, "says Valérie Masson-Delmotte, one of the signatories to Rue89.com. 'Do you think it is normal that we accuse you of being incompetent and that your employer does not defend you? "
The case is on the verge of being embarrassing for the government because it is less than a year ago that the civil government party spoke praise for the former socialist who was even on the verge of being appointed Minister of Industry and renewal. Allegre was however at the last moment the wreck, and therefore, President Nicolas Sarkozy probably avoided a ballad that could have Lars Lokke Rasmussen problems with Thor Pedersen to fade.
Ouch!!
Para el que se quiera ahorrar el tocho resumo: Es escéptico respecto al cambio climático frances más famoso ha sido pillado falseando gráficos en su libro donde argumenta con datos (inventados) que lo del cambio climático es un camelo. Zas!! En toda la boca.
Bueno, no soy muy entendido en biologia, y no voy a leerme las 9 paginas, me lei un poco de la primera, donde ví un enlace de libertaddigital y demás...
Creo que es innegable que el clima está cambiando; las precipitaciones varian de estacionalidad; en noviembre yo iba en manga corta y ahora voy con abrigo...;
El clima siempre está cambiando, lo ha hecho a lo largo de la historia sin pausa.
Que ahora vayas en abrigo y en noviembre en manga corta no significa nada. El año que viene puede ser al reves. Y para el otro se pueden volver a cambiar las tornas. Cualquier persona con una edad medio avanzada a vivido años frios, años calurosos, años secos o años lluviosos en alternancia. Eso no prueba nada.
Para ver un verdadero cambio climaticoa nivel global tienes que irte a escalas de tiempo mayores.
La discusión principal que se está tratando aquí es si el anunciado cambio climatico actual es tan grave como se dice(hay datos que lo afirman y otros que lo niegan), y en que medida es culpable el hombre.
