Reflections – November 1, 2017
Do you ever have mornings when a question plays in your thoughts and you don’t know the answer? This morning, as I gazed at the trees on this first day of November, I wondered if they process carbon dioxide in the winter. The answers I found are fascinating. Maybe everyone else learned this and remembers. But just in case, I thought others might find the answers interesting, too.
The first question that came to mind – Do trees process carbon dioxide (CO2) in winter?
The answer –
“Most of the land mass of the earth is in the northern hemisphere, and most of the vegetation is Northern hemisphere. During autumn and winter, the leaves fall and exhale carbon dioxide (through decomposition). Throughout the spring and summer days, leaves grow and inhale carbon dioxide. So, when it’s winter in the northern hemisphere, global CO2 levels rise quite sharply and fall again during the warmer months.” (Michael Bloch, 2006, November 30. “Deciduous trees and carbon dioxide,” available at greenlivingtips.com).
Another site offered a more global, connected perspective.
“In general, it is inevitable (whether or not trees lose their leaves) that photosynthesis should reduce during the winter months, simply because there is less sunlight through the winter months. The question is as to where greater photosynthesis is happening, in the southern hemisphere (with large oceans, and more marine algae), or in the northern hemisphere (much great land masses), so which winter is the more significant (that of the north or that of the south)? Then you have the additional issue that as oceans get colder in winter, they will dissolve more CO2, and as they get warmer in the summer they will release some of this CO2 back into the atmosphere (this is also made more difficult to judge because of the complexities of the ocean currents).” (The Naked Scientists, 2007, July 10. “Carbon Dioxide in Winter,” available at thenakedscientists.com).
Winter, or rather, below freezing temperatures, affect photosynthesis for coniferous trees as well. (Ayumi Tanaka (2007), “Photosynthetic activity in winter needles of the evergreen tree Taxus cuspidata at low temperatures (2007), Tree Physiology 27, 641–648 © 2007 Heron Publishing—Victoria, Canada).
There is so much to learn about the complex interconnections on earth and how much we all depend on each and every being that shares the same tiny home. The most critical processes are often invisible. It makes me wonder about an educational system that fails in many cases to recognize our interdependence and responsibility for inclusive stewardship. In school, I learned how to dissect things, name all their parts with Latin words, and a little about how other living beings interact with their immediate environments. But we often don’t learn about the interconnections within a larger context, and the importance of helping to maintain the delicate balance necessary for all life to harmonize as each unique being performs its functions as part of a grand symphony throughout the millennia.
I’m grateful for the winter that brings rest for trees and the scent of new fallen snow, even if the air is laden with more CO2.
Reflections – November 6, 2017
The first Monday after
artificial “time” seasonal adjustment
allows me to wake “early”
greeted by the morning sun
streaming through the window
illuminating things that carry memories
with light and a golden glow
I breathe in the light
so rare these days
highlighting poignant memories
of other times and places
The sewing table, now folded,
a legacy from my mother
like the skill I learned as a child
There was a time when I sewed often
with an old secondhand “portable” Necchi machine
if one can honestly call a 50 pound machine portable
but it traveled the country with me
from Los Angeles to Illinois,
to Massachusetts then Connecticut
to Wisconsin, Montana, and back
It’s how I clothed myself at times
and my daughter when she was a child
After decades, I had to retire the Necchi
when it could no longer be repaired
There are days when I can relate
to the feeling that one may no longer
be able to serve a useful purpose
The prayer flags hanging on the open door
symbolize family connections and repaired vision
but I honestly don’t know how
to repair a heart that keeps breaking
from senseless wars and destruction
or from cruelty and tragedy everyday
But today, I awoke to sunshine
with the awareness that I can still breathe
and do small things – trying to be mindful
and compassionate regardless of context
while I am here
