Guest commentary from Juliane Fry, UC Berkeley<\/a><\/small><\/p>\n

On February 9, The Virgin Group chairman Sir Richard Branson announced a $25 million prize for anyone who can demonstrate \u201ca commercially viable design which results in the removal of anthropogenic, atmospheric greenhouse gases so as to contribute materially to the stability of Earth\u2019s climate.\u201d At the press conference announcing this \u201cVirgin Earth Challenge<\/a>\u201d, Branson was joined by Al Gore, and the panel of judges for the competition includes additional climate change celebrities: James Hansen, James Lovelock, Tim Flannery, and Sir Crispin Tickell.<\/p>\n

The goal of the competition is to find a method that will remove at least 1 billion tons of carbon per year from the atmosphere. It will be very interesting to see what ideas come to the fore to scrub CO2<\/sub> from the atmosphere. $25m should encourage some creativity! (and of course, once working should bring in a significant amount of carbon offset money). A ruckus was caused last year when discussion of injecting SO2<\/sub> into the stratosphere to form reflective sulfate aerosols to mask global warming made scientists feel they needed to state their position on this controversial, poorly understood proposal. During the discussion, a New York Times feature (described here<\/a> ) discussed various \u201cgeo-engineering\u201d alternatives to exert a cooling effect to mask global warming. At least in this case, we are not seeking to add something new and uncertain to the atmosphere, but rather, remove something that we added.<\/p>\n

Coment\u00e1rio convidado de Juliane Fry, UC Berkeley<\/a> (tradu\u00e7\u00e3o de F. M. Ramos e I. B. T. Lima)<\/small><\/p>\n

No dia 9 de fevereiro, o presidente do Grupo Virgin, Sir Richard Branson, anunciou um pr\u00eamio de US$ 25 milh\u00f5es para quem demonstrar “a viabilidade comercial de algum projeto para retirada da atmosfera de gases de efeito estufa de origem antropog\u00eanica, para contribuir materialmente para a estabilidade do clima da Terra”. Na coletiva de imprensa que lan\u00e7ou o desafio, batizado de “Virgin Earth Challenge<\/a>“, Branson estava acompanhado de Al Gore, e o corpo de jurados da competi\u00e7\u00e3o inclu\u00eda outras celebridades das mudan\u00e7as clim\u00e1ticas como James Hansen, James Lovelock, Tim Flannery, e Sir Crispin Tickell.<\/p>\n

O objetivo da competi\u00e7\u00e3o \u00e9 encontrar um m\u00e9todo que seja capaz de remover pelo menos 1 bilh\u00e3o de toneladas de carbono por ano da atmosfera. Ser\u00e1 muito interessante observar que id\u00e9ias surgir\u00e3o para varrer CO2<\/sub> da atmosfera. US$ 25M devem suscitar alguma criatividade! (e naturalmente, uma vez implementado, proporcionar muito dinheiro na forma cr\u00e9ditos de compensa\u00e7\u00e3o de carbono). No ano passado, o barulho causado pela proposta de inje\u00e7\u00e3o de SO2<\/sub> na estratosfera para formar uma camada refletiva de aeross\u00f3is de sulfato, de modo a neutralizar o aquecimento global, for\u00e7ou muitos cientistas a tomar uma posi\u00e7\u00e3o clara a respeito desta proposta controvertida e pouco compreendida. Durante os debates, uma mat\u00e9ria do New York Times (descrita aqui<\/a>) discutiu v\u00e1rias alternativas de “geo-engenharia” para criar um mecanismo de resfriamento de mascarasse o aquecimento global. Pelo menos neste caso, n\u00e3o estamos procurando adicionar algo novo e incerto na atmosfera, mas ao contr\u00e1rio, retirar algo que foi adicionado.<\/p>\n

Yar\u0131\u015fman\u0131n amac\u0131 y\u0131lda en az 1 milyar ton karbonu atmosferden \u00e7ekebilen bir y\u00f6ntem geli\u015ftirmek.

Eh, 25 milyon dolar biraz yarat\u0131c\u0131l\u0131\u011f\u0131 te\u015fvik eder herhalde (ve tabii ki, bu yeni y\u00f6ntemler uyguland\u0131\u011f\u0131nda k\u00e2r da artar). Ge\u00e7en sene k\u00fcresel \u0131s\u0131nmay\u0131 maskelemek amac\u0131yla stratosfere SO2<\/sub> aktar\u0131larak yarat\u0131lacak parlak s\u00fclfat taneciklerinin (aerosol) iklimi so\u011futma etkisi tart\u0131\u015f\u0131ld\u0131\u011f\u0131nda bir hayli g\u00fcr\u00fclt\u00fc koptu.

En az\u0131ndan bu sefer, bu 25 milyon dolarl\u0131k yar\u0131\u015fmayla atmosfere yeni ve etkisi hen\u00fcz tam kestirilemeyen bir \u015fey eklemeyen bir \u00e7\u00f6z\u00fcm aran\u0131yor.

Le 9 f\u00e9vrier dernier, Richard Branson, pr\u00e9sident du groupe Virgin, a annonc\u00e9 qu’il offrait 25 millions de dollars \u00e0 quiconque pourra pr\u00e9senter \u00ab une invention commercialement viable qui permette de retirer de l’atmosph\u00e8re les gaz \u00e0 effet de serre d’origine anthropique, de fa\u00e7on \u00e0 contribuer sensiblement \u00e0 la stabilisation du climat de la Terre \u00bb. A la conf\u00e9rence de presse o\u00f9 il annon\u00e7ait son \u00ab \u00ab D\u00e9fi Virgin pour la Terre \u00bb<\/a> \u00bb, Branson a \u00e9t\u00e9 rejoint par Al Gore, et le comit\u00e9 des juges de ce concours comprend d’autres c\u00e9l\u00e9brit\u00e9s du r\u00e9chauffement climatique : James Hansen, James Lovelock, Tim Flannery, et Sir Crispin Tickell.<\/p>\n

L’objectif du concours est de trouver une m\u00e9thode qui pourra retirer de l’atmosph\u00e8re au moins un milliard de tonnes de carbone par an. Il va \u00eatre tr\u00e8s int\u00e9ressant de voir quelles id\u00e9es de nettoyage de l’atmosph\u00e8re vont \u00e9merger. 25 millions de dollars devraient encourager la cr\u00e9ativit\u00e9 ! (et bien s\u00fbr, quand \u00e7a fonctionnera, \u00e7a devrait rapporter une somme significative en cr\u00e9dits de compensations d’\u00e9missions de carbone). Il y eut du grabuge l’ann\u00e9e derni\u00e8re, quand le d\u00e9bat \u00e0 propos de l’injection de SO2<\/sub> dans la stratosph\u00e8re, visant \u00e0 produire des sulfates en a\u00e9rosol r\u00e9fl\u00e9chissant la lumi\u00e8re solaire qui contreraient le r\u00e9chauffement climatique, a donn\u00e9 l’impression aux scientifiques qu’ils avaient besoin d’exposer leur position sur cette proposition mal comprise et controvers\u00e9e.<\/p>\n

Durant ce d\u00e9bat, un article de fond du *New York Times* (d\u00e9crit ici<\/a>) a comment\u00e9 les diff\u00e9rentes options de \u00ab g\u00e9o-ing\u00e9nierie \u00bb ayant un effet refroidisseur contrant le r\u00e9chauffement climatique. Au moins cette fois-ci, on ne cherche pas \u00e0 ajouter quelque chose de nouveau et d’incertain \u00e0 l’atmosph\u00e8re, mais bien \u00e0 en retirer ce qu’on y a ajout\u00e9. <\/lang_fr><\/p>\n\n<\/div> ","protected":false},"excerpt":{"rendered":"
