Cambio climático. Lo que nos preocupa.
Y con, perdón de Zuga, nuestra dosis diaria de cambio climático. Pero, para no ser tan latoso, paso a su aspecto sociológico.
El informe Pew de 22 de enero de 2009 [–>] sobre las 20 mayores preocupaciones del personal USA, que he visto en la web de Roy Spencer [–>]. Que demuestra que estamos un poco locos. Porque si para la mayor parte de los medios de comunicación el mayor problema de la humanidad es el cambio climático (antes calentamiento global), y según los asesores científicos de Obama apenas nos quedan cuatro años para intentar salvarnos del apocalipsis, resulta que para la inconsciente ciudadanía esa es una preocupación muy secundaria. O vigesimaria.
¿O será al revés? Que no es tan inconsciente la ciudadanía, sino que, a la vista de problemas bien reales, ya no tiene ganas de jugar a la enésima fantasía macabra del fin del mundo por culpa del hombre pecador.
Por ejemplo, parece que todo ese deshielo tan acelerado de Groenlandia ya no es para tanto:
Glacier Slowdown in Greenland: How Inconvenient
In this week’s Science magazine, science writer Richard Kerr reports on some of the goings-on at this past December’s annual meeting of the American Geophysical Union.While he didn’t cover our presentation at the meeting in which we described our efforts at creating a reconstruction of ice melt across Greenland dating back into the late 1700s (we found that the greatest period of ice melt occurred in the decades around the 1930s), Kerr did cover some other recent findings concerning the workings of Greenland’s cryosphere in his article titled “Galloping Glaciers of Greenland Have Reined Themselves In.”

So much for Greenland ice’s Armageddon. “It has come to an end,” glaciologist Tavi Murray of Swansea University in the United Kingdom said during a session at the meeting. “There seems to have been a synchronous switch-off” of the speed-up, she said. Nearly everywhere around southeast Greenland, outlet glacier flows have returned to the levels of 2000. An increasingly warmer climate will no doubt eat away at the Greenland ice sheet for centuries, glaciologists say, but no one should be extrapolating the ice’s recent wild behavior into the future.
