The Five-Minute Cloud

IMG_6795.JPG

Everday I watch a cloud for five minutes. Every minute I take a photograph of the same patch of sky where I first started tracking the cloud. Every day I understand a little more and a little less about what's going on .

On Wednesday the small puffy cumulus cloud I chose vanished completely in 3 minutes, leaving me with photos of a patch of blue sky. Because I wanted to post some nice cloud photos with this blog, I turned to antoher part of the sky for another five-minute cloud. 

This time, aimed my camera at a slightly denser cloud. It moved across the sky, it changed its shape, but I could track it over five minutes before it vanished behind the trees. Which made me wonder, when is a cloud a mass that retains its "self" as it moves across the sky and when is a cloud the result of what is happening in a particular patch of the sky at any given time. That is, does the cloud move along--being the same cloud as it moves--or does it form on the leading edge and dissipate on the traling edge so that it seems to be the same cloud. 

This meteorological conundrum reminds me of the problem of the soul, of the self, of knowing how much of "me" remains "me" over time every  cell in my body is constantlly being renewed (at different rates and not precisely every 7 years as the myth holds).  

The water that makes up clouds, like the cells that make up our bodies, are in a state of constant flux. Clouds are more dynamic and life out their lives in moments not years. The kind of change and the speed of change within a cloud is mind-boggling and only a fraction of it is visible to us with the naked eye. In addition to the visible water molecules that make up a cloud, there are invisible molecules of water vapor influencing the form of the cloud.
 

The "cloud" we think we are watching is both a product of the atmospheric conditions in a particular patch of sky (which bring it into existence) and also an entity which moves as a unit for a while until the atmospheric conditions change and transform the cloud and we no longer recognize it. 

At what point does the cloud we started watching become a different cloud? Well, at what point does a loved one's face age? 

All the time and never. Take a look at this cloud. I watched it for five minutes, but I didn't notice the changes it was undergoing until I looked at my photographs, taken one minute apart..

Misperceptions About Marbled Murrelets

  I was going to write about the clouds this morning, but was Google alerted this morning to a blog posting on the marbled murrelet.  Because the blog comes from a timber-industry group, the Washington Forest Protection Association, and because my book, Rare Bird: Pursuing the Mystery of the Marbled Murrelet,  is mentioned in the article, and because my book was used by the timber-industry blogger to support  the state's logging of  murrelet nesting habitat, I need to defend myself.  Again.

  Again, but differently.

  Back in May, I was politely accused in a Crosscut article of having ignored the scientific research documenting a potential cause of the crashing marbled murrelet populations: depletion of the fish the murrelet's feed on. I politely and fully defended myself in this blog posting. The research I had not included in Rare Bird in 2005 when my book was first published was published after I had completed my writing. When I explained this to the author of the Crosscut article, Eric Scigliano, he politely ate a tiny bit of crow and added a note at the end of his online article mentioning that I was addressing these and other newly documented threats in the paperback edition of Rare Bird (just released by Mountaineers Books).

  Unfortunately, Scigliano's article remained online. Unfortunately, Ashley Bach, the Washington Forest Protection Association shill (sorry, but it's true) used the article to support the timber industry's popular new mantra: the murrelets problems are caused in the ocean, not by logging.  

  This is a convenient misperception. Convenient, facile, irresponsible, but sadly typical in the blame game being played at the expense of the marbled murrelet. Everyone is to blame for the murrelet's declining population--30% between 2001 and 2010 in Washington, Oregon, and California.

 While no one will dispute the oceans have become increasingly inhospitable to marbled murrelets (and all other marine life forms), no one who has read the science carefully (or at all) would dare dispute the well-documented fact that the primary cause of the murrelet’s decline is—and has always been—the removal of the murrelet’s nesting habitat (aka logging).

Here is how the Scientists put it : "Marbled Murrelet (Brachyramphus marmoratus) populations have declined over much of their range due primarily to current and historic loss and fragmentation of older-aged forest breeding habitat (USFWS 1992, Nelson and Hamer 1995, Burger 2002, McShane et al. 2004, Peery et al. 2004, Becker and Beissinger 2006, Piatt et al. 2006, Hébert and Golightly 2007, Lynch et al. 2009, Miller et al. 2012). "
