By Johan Galtung*, 29 Sep 2014 – TRANSCEND Media Service – “Trees won’t save the planet” is the title of an article in INYT (21-22 Sep 2014) by Nadine Unger, professor of atmospheric chemistry at Yale University. Her thesis: The conventional wisdom–that planting trees serves carbon capture–is wrong; it is all much more complex.

Photosynthesis is only one factor. Another factor for global warming is how much of the solar energy is absorbed by the earth’s surface and how much is reflected. Trees, being dark, absorb; the net balance may be chilling in the tropics and warming elsewhere.
But there is more to it. Trees emit VOCs, “volatile organic compounds”, for their own protection. Mixing with pollution from cars and industry “an even more harmful cocktail of airborne toxic chemicals is created”, producing methane and ozone. Research at Yale seems to indicate that this affects global climate on a scale similar to surface color and carbon storage capacity.”
Trees and soil also breathe oxygen and release CO2. The Amazon forest produces oxygen during the day and reabsorbs at night; a closed system. Moreover, eventually trees die or burn and “the carbons finds its way back into the atmosphere”.
The old story. Search for one factor causing an evil–like CO2 causing global warming–and act to remove that one cause; the present mainstream dogma. But research points at many other factors involved and they may all be ambiguous. Yin-yang in other words, forces and counter-forces, and holism, expanded visions. A daoist vision.
So let us move East, to a retired professor of natural resources at Nagoya University in Japan, Kunihiko Takeda. And to professor in geophysics Shigenori Murayama at the Tokyo Institute of Technology who has very similar views (Google both of them.) Summers will be hotter, winters colder. Net balance?
Some key points from Takeda[i]:

This author is not in a position to take a stand for or against the CO2 hypothesis, or what is better for life, warming or chilling relative to the present level. The position taken here is in favor of more complex and particularly more dialectic views: there may be more to it, action generates re-action. For views in favor of the mainstream see http://www.realclimate.org, for skeptics see http://www.sepp.org.
Maybe Takeda underestimates the dangers of warming. But a striking point in his analysis is the role attributed to urbanization. Or concretization, covering soil with concrete, settling on top of it in huge mega-congregations with waste as lifestyle.
De-urbanization would be a consequence of Takeda’s points. Some of this may be happening in some places; people moving into smaller, more village-like communities, decentralization of administration made possible by the Internet. Leaving more to nature’s wisdom than to the human lack thereof, and particularly to the market’s lack thereof.
In 1972 when “limits to growth” became mainstreamed, I warned against the missing class perspective within and between countries[iii].
Nothing new about depletion and pollution. The West had been depleting resources of the colonies for ages, and working-class districts had always been polluted. Novelty was middle and upper classes in middle and upper countries being hit. Like wars not hitting only women, children and periphery countries, but right at the center of the Center, the West.
Conclusion: re-search, re-think, re-act; not one factor, CO2, and one problem, warming. There is more in the world. Move forward with good, proven examples, not with a “multilateral consensus” reflecting power structures and vested interests more than a complex reality.
