\nNell’articolo di Arthur Neslen sul <\/span>Guardian <\/a><\/strong><\/em>scopro, in ritardo, che\u00a0<\/span>Brian Ricketts, segretario generale della lobby europea del carbone (1), si lamenta dell’intolleranza dei 195 governi, dei manifestanti presenti al vertice di Parigi sul clima e dell’ONU che \u00e8 riuscita a lavare il cervello alla popolazione mondiale. Prevede che Big Coal <\/span><\/p>\n

sar\u00e0 odiata e denigrata cos\u00ec come sono stati odiati e denigrati i mercanti di schiavi.<\/em><\/p>\n

Andavano amati e celebrati anche loro, poveri tesori. Neslen si meraviglia:<\/p>\n

Ricketts is an affable and respected figure on the Brussels lobby scene, and campaigners suggested that stress and industry desperation may have played a part in his outburst.<\/em> \u00a0In the aftermath of the Paris agreement,\u00a0shares in coal firms plunged rapidly<\/a>. Peabody, the world\u2019s largest coal firm, saw stock values drop 12.6%, while Consol Energy holdings was down by 3.3%. <\/em><\/p>\n

Le azioni della Peabody sprofondavano da prima ancora della condanna per aver ingannato gli azionisti con bufale sul clima, comprate da scienziati neghisti<\/del>\u00a0negaioli a 250 dollari\/ora. Gli affari di Big Coal vanno male, lo dicono tutti<\/a><\/strong>, ma se andassero a gonfie vele non ci sarebbe bisogno del signor Ricketts.<\/p>\n

I suoi piagnistei mi ricordano tanto quelli di Rinaldo Sorgenti, il vice presidente di Assocarboni su Oggi Scienza, qui, sul blog della…
\nMa guarda!<\/p>\n

Sul blog della SCI<\/strong><\/a> scopro, meno in ritardo, che il prof. Zingales, presidente della Societ\u00e0 Italiana di Chimica\u00a0<\/del>Consiglio Nazionale dei Chimici (h\/t prof. Zingales<\/a>),\u00a0non legge n\u00e9 il blog della SCI n\u00e9 il giornale della SCI<\/a>, ma si lamenta dell’incompetenza e dell’intolleranza in materia di gas serra e di fertilizzanti di certi chimici che scrivono sul blog della SCI. Si lamenta anche per il termine “neghista”. Un blogger suggerisce “negaiolo” che suona pi\u00f9 festivo, lo adotto subito. <\/span><\/p>\n

Ammiro la tolleranza del prof. Zingales che non ha mai protestato contro le bufale sul clima pubblicate sul giornale della SCI\u00a0.\u00a0<\/em><\/span><\/p>\n

(1) Come negli USA, i suoi lobbisti<\/a> sono stati pagati per denigrare<\/a> <\/strong>la European Climate Foundation<\/a> e le Ong che essa sostiene perch\u00e9 rimedino ai danni sanitari, ambientali e climatici causati dalla filiera del carbone.<\/p>\n

Babbo Natale rischia la bancarotta per colpa del riscaldamento globale antropogenico, dice in un’intervista<\/a> in esclusiva:<\/p>\n

I used to worry about hitting a polar bear on the pad. Now I worry about whether my whole transportation system will crash and sink below the ice on the Dec. 24 countdown. And who knows what lies below the polar ice cap.<\/em><\/p>\n

A ri-proposito, Kevin Anderson <\/a><\/strong>del Tyndall Centre critica l’Accordo di Parigi<\/a>:<\/p>\n

The climate agreement delivered earlier this month in Paris is a genuine triumph of international diplomacy. It is a tribute to how France was able to bring a fractious world together. And it is testament to how assiduous and painstaking science can defeat the unremitting programme of misinformation that is perpetuated by powerful vested interests. It is the twenty-first century’s equivalent to the victory of heliocentrism over the inquisition. Yet it risks being total fantasy.\u00a0<\/em>(…)
\nReducing emissions in line with 2 \u00b0C remains a viable goal \u2014 just. But rather than rely on post-2050 BECCS – <\/em>biomass energy carbon capture and storage, ndr\u00a0– deciding to pursue this alternative approach would have begged profound political, economic and social questions. Questions that undermine a decade of mathematically nebulous green-growth and win\u2013win rhetoric, and questions that the politicians have decided cannot be asked.<\/em>
\nMove away from the cosy tenets of contemporary economics and a suite of alternative measures comes into focus. Technologies, behaviours and habits that feed energy demand are all amenable to significant and rapid change. Combine this with an understanding that just 10% of the population is responsible for 50% of emissions, and the rate and scope of what is possible becomes evident.<\/em><\/p>\n

Evidente?<\/p>\n

Dai monti di Marte d’estate scorre acqua salata? Macch\u00e9, CO2, scrivono<\/a><\/strong> C\u00e9dric Pilorget e Fran\u00e7ois Forget su Nature Geoscience.<\/em> Dal com. stampa:<\/p>\n

A quelques centim\u00e8tres sous les pentes martiennes sur lesquelles le CO2 se condense, on trouve toujours un “perg\u00e9lisol” form\u00e9 de grains ciment\u00e9s par de la glace d\u2019eau. Ainsi lorsque la glace de CO2 se condense sur le sol en hiver, l\u2019air pr\u00e9sent dans les pores et interstices du sous-sol imm\u00e9diat se retrouve confin\u00e9, pris en sandwich entre le perg\u00e9lisol \u00e9tanche et la couche de glace de CO2 \u00e0 la surface.\u00a0<\/em>
\nDans ces conditions, les simulations num\u00e9riques de C\u00e9dric Pilorget et Fran\u00e7ois Forget ont r\u00e9v\u00e9l\u00e9 des ph\u00e9nom\u00e8nes \u00e9tonnants. A la fin de l\u2019hiver et au printemps, les rayons du Soleil passent au travers de la couche de glace de CO2 translucide et la chauffe par la base. La glace de CO2 ne fond pas, mais se “sublime”, en passant directement en phase gazeuse. Le gaz produit se diffuse dans le proche sous-sol poreux. Une partie peut s\u2019y recondenser tandis que le reste du gaz s\u2019accumule dans l\u2019espace poreux restant, augmentant consid\u00e9rablement la pression dans le proche sous-sol, jusqu\u2019\u00e0 plusieurs fois la pression atmosph\u00e9rique. Cette surpression finit par fracturer la glace de surface, ce qui g\u00e9n\u00e8re une violente d\u00e9compression. Les pores du sous-sol sont alors travers\u00e9s de puissants flux d\u2019air li\u00e9s \u00e0 l\u2019\u00e9vacuation du surplus de gaz et \u00e0 la sublimation rapide de la glace de CO2 du sous-sol. En quelques minutes, voire quelques secondes, plusieurs m\u00e8tres cubes de gaz (voire m\u00eame plusieurs dizaines de m\u00e8tres cubes au niveau des fractures) diffusent verticalement vers la surface. De tels flux sont capables de d\u00e9stabiliser les grains situ\u00e9s sur les pentes et ainsi de provoquer des \u00e9boulements et des coul\u00e9es. Surtout, la pression du gaz peut entra\u00eener une v\u00e9ritable fluidification de l\u2019avalanche, et lui donner les propri\u00e9t\u00e9s d\u2019un \u00e9coulement liquide.\u00a0<\/em>
