Drunken Trees

The other week the busy little bees who are working on Nobel AlÕs
new bookÉ what, you didnÕt know Gore was working on a new book? Yep, apparently
in the works is a book on climate change and its solutions, supposedly titled
ÒA Path to SurvivalÓ in which Gore lays out, well, you can probably figure that
out. As we have detailed previously Gore is more than just a little out there
when he starts talking about the climate change threats to humanÕs
survivability on Earth. So, we donÕt yet know whether his new title will be
shelved in the science or science fiction section.
But, as we were saying, the other week the busy little bees who
are helping out on Al GoreÕs new book sent a call out looking for photographs
or other particularly useful information that could be used to illustrate the
impacts of melting permafrost and changes to the environment that may result.
The request was for images or charts that could be incorporated in a chapter on
Òpermafrost meltingÓ (as a technical point, because weÕre sure that Gore will
be paying more attention to the details this time around, permafrost—any
type of soil that spends most of its time below freezing, whether or not any
water is present—doesnÕt ÔmeltÕ but rather, it ÔthawsÕ). And although it
wasnÕt specifically mentioned, weÕre sure they meant ÒThe more dramatic the
better!Ó
Always interested to help out, we thought that weÕd offer up a few
images that we recently came across in our on-going effort to compare current
conditions in the Arctic with conditions earlier in the 20th century.
Figure 1 shows a Òthaw sinkÓ in the middle of a cultivated field
that resulted from the thawing of an ice mass buried in the ground. Not
dramatic enough? Well how about Figure 2.

Figure1. Photo showing a sinkhole that resulted from a thawing
of subsurface ice body (see references for source of photo).
Figure 2 shows a stand of spruce trees that are off-kilter as the
permafrost they were growing on thawed and began eroding away. WeÕre sure that
GoreÕs staff will like this one! Why? Because the book version of The
Inconvenient Truth featured a two-page spread of Òdrunken treesÓ that were
Òleaning every which wayÓ from thawing soil beneath them and Gore pining ÒThese
trees put their roots deep into the frozen tundra decades—even
centuries—ago and now as the tundra melts they lose their anchor, causing
them to sway in all directions.Ó

thawing of permafrost beneath their roots (see references for source of photo).
Oh, as for the photographs being in black and white, well thatÕs
sort of a give away that they were taken back in the early 1950s, more than a
half-century ago. That pretty much assures that Gore wonÕt be using them in his
new book, as the alarming quality of images of Òdrunken treesÓ and sinkholes is
effectively lost if everyone were to know that the conditions producing them
today were not so different than the ones that existed in the not-too-distant
past.
