We're
in uncharted territory. No one knows for sure how
bad will be the effects of climate change or what exactly will happen.
Speaking
of positive feedback loops, inter-related are the current rate of species extinction
and global warming. The Holocene, or
Sixth Extinction refers to the current period of mass species extinction that
we’ve all been hearing about since we were kids, except we didn’t think it was that
bad. What we learned as kids, with pleas
to save the whales, has snowballed into an avalanche of extinctions that has
become an event in itself. Elizabeth
Kolbert has described it in detail in her Pulitzer Prize winning aptly named book,
The Sixth Extinction. Here is a succinct
summary of the present-day mass extinction, in which we may be included.
It Gets
Worse
Guy
McPherson is Professor Emeritus of Natural Resources and Ecology & Evolutionary
Biology at the University of Arizona. McPherson is gaining attention as a
scientist who believes we humans will be extinct – yes, extinct – in as little
as fifteen years. You can find
McPherson's website Nature Bats Last and blog here.
I
learned about McPherson while commuting to work and listening to an interview
with him on the Canadian Broadcasting Corporation’s (CBC) Radio One. The strength of the following video, Guy McPherson, Full Presentation, York, UK, is the breadth of his overview of
sources. It’s heavily referenced.
I wish McPherson’s
comments were as measured as his monotone is flat. I’d prefer if he did not inject dark humour and
political asides into the lecture. That
said, there is a solid overview of his position and a goldmine of reference
material in this short half hour or so lecture.
Plus,
for McPherson, the upshot of it all is refreshingly measured: pursue love and live
a life of excellence. He’s not asking anybody
to join him in a commune and drink the purple Kool-Aid. One could quibble, asking why a scientist is
moralizing at all. But given his conclusions,
it’s helpful to see how moderate his “so what?” is. Pursue love and live a life of
excellence. In fact, it sounds familiar:
The end
of all things is at hand; therefore be self-controlled and sober-minded for the
sake of your prayers. Above all, keep
loving one another earnestly...
