Il climatologo Raymond Pierrehumbert <\/a><\/strong>ha sempre avuto dubbi sui progetti di geoingegneria, il cosiddetto “Piano B” per limitare l’aumento della temperatura faute de mieux.

Raypierre ribalta le analogie terapeutiche usate dalla “geoclique di Harvard” nei media:<\/p>\n

Few scientists have the stomach for this subject, geoengineering isn\u2019t attracting much new talent, and the modest burst of funding that came in the wake of the UK Royal Society report has mostly collapsed. What little funding remains is mostly directed, as it should be, on approaches involving governance, notably the\u00a0Carnegie Council Initiative<\/a>, which is an interesting endeavor. But I worry a bit that the effort has been infiltrated by the geoclique. So far as scientific research directed towards field experimentation goes, Harvard\u2014with the help of Bill Gates and other private funds\u2014is almost single-handedly keeping the field on life-support. But it is time to pull the plug on this ill-advised approach.<\/p>\n

One of the albedo modification scenarios we considered in the National Research Council report<\/a> is the \u201cGreenfinger\u201d scenario, in which a well-meaning, wealthy individual decides to save the world on his own, but with possibly disastrous unintended consequences. It is ironic that Harvard, my very own alma mater, appears to be setting itself up for that very role. [link aggiunto]<\/p>\n

Tra i fautori dell’albedo hacking, c’\u00e8 anche l’Economist<\/em>\u00a0preoccupato dai costi del riscaldamento globale. Questa settimana in “The Frozen Rodeo<\/a>” racconta degli iceberg nell’Atlantico Nord – si staccano dalla calotta groenlandese – “catturati con il lasso” e rimorchiati a distanza di sicurezza, per evitare alle piattaforme petrolifere la fine del Titanic.\u00a0<\/em><\/p>\n

L’Economist<\/em> vanta\u00a0<\/a>anche la rivoluzione sociale e governativa della crittografia blockchain, per esempio nel garantire contratti di propriet\u00e0 e impedire il land-grabbing. Anche secondo l’ecologo\u00a0Guillaume Chapron<\/a> su Nature<\/em>, “The environment needs cryptogovernance<\/a>” ma<\/p>\n

There are obstacles. Bitcoin is slow: it is limited to 7 transactions per second, compared with an average of 2,000 transactions per second for the Visa credit network. To run and check its complex algorithms, Bitcoin requires a network of dedicated ‘mining farms’ of high computing power, most of which are based in China, Georgia, the United States, Canada and Sweden (see also\u00a0Nature\u00a0526,\u00a021\u201323; 2015<\/a>). These use a comparable amount of electricity to whole cities. Bitcoin is estimated to consume about 10.4 terawatt hours a year, <\/strong>almost twice that used by Google as a company (5.7 TWh).

\u00c8\u00a0uscita la seconda edizione di Presence and Proximity: To Stay and Deliver<\/a><\/em><\/strong>, il rapporto dei consulenti statunitensi\u00a0Humanitarian Outcomes<\/a> sulle Ong internazionali, agenzie dell’Onu incluse. Ha la stessa visione assistenzialista di sei anni fa (per non dire imperialista), secondo me. Sar\u00e0 vero che ci sono stati “subappalti” inaccettabili, ma dire che<\/p>\n

Many humanitarian organizations were still found to approach risk and key decisions surrounding evacuations, returns, and the use of remote management based on relatively weak analyses and vague perceptions rooted in media coverage of particular crises.<\/p>\n

significa sottovalutare la crescita, l’autonomia, l’empowerment ecc. delle Ong locali proprio dove ci sono “particolari crisi”, a cominciare dalla Siria e paesi confinanti.<\/p>\n

Punto di vista dissonante dal Guardian<\/a><\/em>.<\/p>\n

Science denial<\/strong><\/p>\n

Mi piacerebbe vedere “i dati”, ma non\u00a0ho accesso a Studies in History and Philosophy of Science.<\/em>\u00a0Dall’abstract<\/a><\/strong>:<\/p>\n

Several characteristics are identified that distinguish science denialism from other forms of pseudoscience, in particular its persistent fabrication of fake controversies, the extraordinary male dominance among its activists<\/strong>, and its strong connection with various forms of right-wing politics.

La Turchia blocca l’accesso a Wikipedia ed\u00a0elimina<\/a>\u00a0l’insegnamento dell’evoluzione; fra le condizioni dettate dall’Arabia Saudita per mettere fine all’embargo del Qatar, c’\u00e8 la chiusura<\/a> di Al Jazeera; in USA un boss del carbone querela<\/a> il comico John Oliver per un esilarante\u00a0monologo sui minatori<\/a>; il governo Trump vieta l’uso di telecamere e registratori<\/a> durante le proprie conferenze stampa…<\/p>\n
