Last week I gave a talk on climate change and pandemic influenza at the University of Washington. My presentation was a part of the Biological Futures in a Globalized World series held at the Simpson Center for the Humanities.

I was initially dubious about a connection between the crises until, as these things go, I investigated further. There appear a number of mechanistic relationships tying together the two catastrophes.

There may be a number of ways out of the jams as well, as millions of farmers around the world are advancing alternate futures right out from underneath agribusiness.

UPDATE. We should add another possible connection between climate change and influenza not in the presentation.

According to Shaman and Lipsitch (2012), the last four pandemics (1918, 1957, 1968 and 2009) were preceded by La Niña conditions that, changing patterns of waterfowl migration, may have rejuxtaposed serotypes and prompted new reassortants. As Mother Jones‘ Kiera Butler points out, reporting on this year’s H1N1 (2009) influenza, climate change affects the El Niño–Southern Oscillation.

Broiler explosion11In our H7N9 post we described the possibility reducing finishing time may select for greater virulence in influenzas. That is, reducing the age at which poultry are sacrificed may select for increasing the damage influenza incurs.

There may be immunological fallout as well,

By increasing the throughput speed, and reducing the age of food animals at slaughter, the livestock industry may also be selecting for strains able to transmit in the face of younger, more robust immune systems, including, should spillover occur, in humans.

A million minds momentarily magnetizing themselves along the same axis can turn a country’s deepest despair into an ecstatic sprint for freedom. What a people find revolting–a dictator decorated in American apologia–can be turned by a people’s revolt ridiculous.

No wonder so much effort (and money) is daily expended on propaganda in countries around the world. Obedience–the notion the rulers rule–is at its heart precarious.

But once a hypnosis is broken and history lurches forward, those who are unable to come to terms with the new order are left behind. They are relics, trivia, answers to riddles lost in the sand blowing about the noseless sphinx of empire. Egyptian President Hosni Mubarak and his Washington supporters, Anthony to Mubarak’s Cleopatra, were so startled by January 25th’s uprising that nearly a month later each party still hadn’t grasped their newfound irrelevance.
