I would dearly love to see an element called levium, after the writer and chemist Primo Levi. His\u00a0<\/em>The Periodic Table\u00a0(Einaudi, 1975) remains the best book ever written about chemistry, and it would please my sense of irony to see a superheavy element given a name that could be interpreted as a reference to lightness.<\/em>
\nYet this is not just about levity. Levi\u2019s account of his time in the Auschwitz concentration camp, 1947\u2019s<\/em>\u00a0If This Is a Man, is one of the century\u2019s most profound and humane works, testament to fact that science can be a liberating, universal force for salvation, while recognizing its potential to be abused in terrible ways.”<\/em><\/p>\n

Jeff Tollefson<\/a><\/strong> parla del paper<\/a><\/strong> di Christopher Elvidge et al. uscito il 25 dicembre (!), con l’analisi dei dati raccolti per un anno dalla NOAA:
\nIn 2012, a total of 7467 individual flare sites were identified. The total flared gas volume is estimated at 143 (\u00b113.6) billion cubic meters (BCM), corresponding to 3.5% of global production. While the USA has the largest number of flares, Russia leads in terms of flared gas volume. Ninety percent of the flared gas volume was found in upstream production areas, 8% at refineries and 2% at liquified natural gas (LNG) terminals.\u00a0<\/em>
\nBruciare quel bendid\u00eco (valore circa $20 miliardi)produce oltre 350 milioni di tonnellate di CO2. Ma catturare tutto il metano alla fonte -salvo rischio d’incidente – costerebbe sui $100 miliardi. \u00a0Scrive J. Tollefson:
\nThe World Bank aims to end routine gas flaring at oil production sites around the world by 2030, in an\u00a0initiative<\/a>\u00a0launched last year. Some 45 governments, organizations and oil companies had signed up to the plan by the end of the international climate negotiations in Paris.<\/em>
\nI produttori vogliono sovvenzioni per risparmiare gas perch\u00e9 i $2 miliardi\/giorno che ricevono per estrarre combustibili fossili non sono sufficienti?<\/p>\n","protected":false},"excerpt":{"rendered":"
