Por qué el calentamiento global es bueno para el mundo

Matt Ridley, autor de The Origins of Virtue, uno de los libros que más he disfrutado, nos obsequia con un post que dice exactamente eso:

Why climate change is good for the world

Climate change has done more good than harm so far and is likely to continue doing so for most of this century. This is not some barmy, right-wing fantasy; it is the consensus of expert opinion. Yet almost nobody seems to know this.

  1. Ridley es realmente bueno escribiendo, y la argumentación se sostiene.
    Una duda -talebiana- me surge: ¿Qué pasa con los “unknown unknowns”? Que el planeta suba dos grados de temperatura globalmente va a tener muchos otros efectos que los que los estudios actuales predicen. ¿Podemos realmente estar seguros de que no hay cisnes negros por ahí que provocarían auténticas catástrofes? Ante la duda ¿No es mejor reducir las emisiones de CO2?

    • No no. El acepta esa posibilidad. Su propuesta es mucho más humilde. El simplemente quiere que se acepte la realidad de la situación actual, independientemente de su interpretación:

      You can choose not to believe the studies Prof Tol has collated. Or you can say the net benefit is small (which it is), you can argue that the benefits have accrued more to rich countries than poor countries (which is true) or you can emphasise that after 2080 climate change would probably do net harm to the world (which may also be true). You can even say you do not trust the models involved (though they have proved more reliable than the temperature models). But what you cannot do is deny that this is the current consensus. If you wish to accept the consensus on temperature models, then you should accept the consensus on economic benefit.
