Anticipazioni sul prossimo rapporto dell’IPCC

di Carlo Carraro

Mancano solo poche ore alla pubblicazione ufficiale della prima delle tre sezioni del Quinto Rapporto di Valutazione dell’ IPCC, l’attesissimo volume che raccoglie lo stato dell’arte a livello scientifico delle conoscenze globali sul clima. In quanto membro del Bureau dell’IPCC e Vice Presidente del Working Group III ho avuto accesso in anticipo al rapporto. I contenuti delle bozze del rapporto sono trapelati in più di un’occasione nel corso dell’anno (si vedano i precedenti post sull’argomento: “IPCC: la bozza trapelata che invade il web” e “Polemiche sul (futuro) Quinto Rapporto dell’IPCC”), e i media di tutto il mondo non hanno mai perso l’occasione di fare notizia con stralci di informazioni rubate qua e là.

Top climate scientists admit global warming forecasts were wrong

A leaked draft of a report by the UN Intergovernmental Panel on Climate Change is understood to concede that the computer predictions for global warming and the effects of carbon emissions have been proved to be inaccurate. The report, to be published later this month, is a six year assessment which is seen as the gospel of climate science and is cited to justify fuel taxes and subsidies for renewable energy.

Vers une élimination des supergaz à effet de serre HFC

La coalition contre les super-gaz à effet de serre s’élargit. Après l’accord bilatéral intervenu entre les Etats-Unis et la Chine en juin, les pays du G20 se sont quittés, vendredi 6 septembre à Saint-Pétersbourg, en affichant leur volonté de s’attaqueraux gaz à courte durée de vie et plus précisément aux HFC (hydrofluorocarbones). Ces substances, aux pouvoirs de réchauffement plusieurs centaines de fois supérieurs au dioxyde de carbone, le principal gaz à effet de serre, sont utilisées dans les systèmes de réfrigération et de climatisation.
