En un reciente art\u00edculo en la revista [\u00abNature\u00bb:http:\/\/www.nature.com\/nature\/journal\/v439\/n7073\/full\/nature04420.html], un grupo de cient\u00edficos europeos ha descubierto que las plantas producen metano en condiciones normales. \u00bfY qu\u00e9? Pues resulta que el metano es uno de los principales gases del llamado [\u00abefecto invernadero\u00bb:http:\/\/es.wikipedia.org\/wiki\/Efecto_invernadero]. Esta \u00abfuente de metano\u00bb todav\u00eda no se hab\u00eda tenido en cuenta en los modelos de cambio clim\u00e1tico y ha levantado olas de pesimismo entre los expertos, ya que: si las plantas emiten metano, y estas emisiones aumentan con la temperatura, el cambio clim\u00e1tico actual se incrementar\u00e1 con un bucle de realimentaci\u00f3n imposible de parar.
\nLa \u00abeditorial de la revista Nature\u00bb:http:\/\/www.nature.com\/nature\/journal\/v439\/n7073\/full\/439128a.html no es muy alentadora:<\/p>\n
\n\u00abIt is too early to say exactly how the revelation might influence predictions for future climate change, but it’s unlikely to be good news. The fact that plant methane emissions rise with temperature, and that plants are likely to grow faster in a warmer climate anyway, could lead to a big rise in methane emissions from natural sources, says Johannes Lelieveld, an atmospheric researcher at the Max Planck Institute for Chemistry in Mainz, Germany.
\nThe finding also restricts our options for reducing methane emissions, he points out, because measures such as growing rice in drier fields are likely to prove less effective than had been thought. \u00abIf natural greenhouse-gas sources are greater than we thought, the scope for climate politics becomes narrower,\u00bb he says. \u00abYou wouldn’t cut down forests just because trees release methane.\u00bb\u00bb<\/p><\/blockquote>\nVer adem\u00e1s:
