A Farmer’s Conscious Mediation: Enable Life & Recycle Carbon Emissions
By Glenn Gall, Climate Activist and Farmer based in Oberlin, Ohio
Preparing for 350.org's Silver Anniversary on April 7, 2013
“If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, ... CO2 will need to be reduced from its current 385 ppm to at most 350 ppm.... If the present overshoot of this target CO2 is not brief, there is a possibility of seeding irreversible catastrophic effects.” - Dr. James Hansen, et al, 4-7-2008
How time flies!
It's been twenty-five years since the earth’s atmosphere climbed to
and stayed above the milestone, and threshold, 350 ppm CO2 level, up
from 280 or so a couple centuries ago. Over the last 25 years, the CO2
level has continued to climb, and is now approximately 395 ppm.
There
are now approximately 800 gigatons (Gt) of atmospheric carbon (carbon dioxide in Earth's atmosphere), and
there were around 600 Gt when the atmosphere had less than 300 ppm CO2.
Well over 100 Gt carbon would have to be removed from the atmosphere
and added to biomass and soil for us to reach or go below 350 ppm CO2.
That will take more than just reducing Greenhouse gas emissions, which has been where
most of the stop-global-warming effort has been focused.
Five
years ago, when Dr. Hansen and colleagues disclosed 350 as the limit,
there was considerable buzz around the idea and the number. In the
last couple of years, that buzz and activity has given way to
preventing two degrees of rise in temperature instead. It is baffling
that we could ignore dire warnings of “irreversible catastrophic
effects” that remaining above 350 brings. If the target is overshot,
do we simply slow down or stop? We are already in trouble. We need to
reverse our course immediately!
Burning the fossil
fuels that used to be living things creates CO2 and water.
Photosynthesis is more or less the reverse, turning CO2 and water vapor
back into life. It pulls CO2 out of the atmosphere. Generating
enough more abundance of vegetation can actually draw down atmospheric
carbon levels, picking up where emission reductions leave off.
Rapid
growing trees and shrubs can capture carbon and store it indefinitely
if maintained. Likewise, grassland species which feed the soil and
result in stable topsoil humus that can, if well managed, rapidly
recycle the carbon we have emitted and left in the atmosphere. It makes
sense to enable more life while recycling our carbon emissions.
There
may be significant emission reductions this decade, but whether or not
that happens, we can still foster more life. Not only will that draw
carbon out of the atmosphere, but it can help make our planet more
resilient, reduce or reverse desertification, prevent extinctions,
reduce flooding and drought impacts, and feed people, all desirable
outcomes even if global warming weren’t an issue. Generating more life
is an enormous opportunity, and our only real, safe way to reach or go
below the 350 threshold.
Fortunately a sea change in
our understanding and practice has begun. There are many who are
working tirelessly to share what they know and help others grow
healthy, more nutritious crops without harmful chemicals, harvest
rainwater in the soil so that plants can grow, and provide more abundant
landscapes, while annually sequestering tons of CO2 per acre.
Perennial
systems are one key. Grasses can be managed to rapidly grow topsoil.
Trees, shrubs, forbs, all can provide food and other necessities
without topsoil erosion while sinking and sequestering carbon.
On
his “pasture cropping” farm in in New South Wales, Australia, Colin Seis sequesters thousands of tons of CO2 per year, while economically
and ecologically growing food. Not only that, there are now over 2000
other practitioners of his Pasture Cropping system in Australia.
That
kind of impact is monumental and earth changing. Australia’s soils are
well on their way to capturing more CO2 then emitted on the continent.
Seis and followers are showing us how effective we can be if we let
nature work for us.
Can more of us commit to promoting
carbon farming methods like these, or to helping farmers with their
chores or marketing, or to becoming farmers?
Imagine
the impact of such commitments. This spring, let us recognize that we
have been in the danger zone for 25 years too long, understanding that
we have been made aware of the danger five years ago.
We are now on a
powerful trajectory, one that will empower thousands and millions more
holistic, carbon sequestering farmers, and their customers, aids, and
agents, and that will take us below the danger level. Because of this,
let us celebrate that we are enabling a stable climate for all
foreseeable generations.
Does your farm capture more
carbon that is emitted, or do you help or support such a farmer or
farmers? Does what you do account for more carbon sequestered than you
emit? Are you committed to enabling more stable soil and biomass
carbon in the not too distant future?
If so, consider
organizing a celebration for April 7, 2013, the fifth anniversary of
the recognition of 350 as a limit for a healthy planet.
With enough support, we won't be waiting another 25 years to see 350 ppm, or a stable climate, and all that it brings.
