Cost Of Carbon

By Willis Eschenbach – Re-Blogged From http://www.WattsUpWithThat.com

I see that Andrew Revkin continues to try to keep the climate pot bubbling. In this case, he’s issued dire warnings about reducing the so-called “Social Cost of Carbon” (SCC). He starts by defining the SCC

This value is the government’s best estimate of how much society gains over the long haul by cutting each ton of the heat-trapping carbon-dioxide emissions scientists have linked to global warming. balance-scale

Currently set at $36 per ton of carbon dioxide, the metric is produced using a complex, and contentious, set of models estimating a host of future costs to society related to rising temperatures and seas, then using a longstanding economic tool, a discount rate, to gauge how much it is worth today to limit those harms generations hence. (For context, the United States emitted about 5.1 billion tons of CO2 in 2015, out of a global total of 36 billion.)

Now that makes it all sound very scientific, but let’s be clear about these claimed “harms generations hence”.

The Social Cost of Carbon (SCC) is a GUESS about the unknown future economic effects that might or might not result from unknown future temperature changes that might or might not result from unknown future CO2 emissions changes that might or might not happen over the next century.

Benefits of Carbon Dioxide: Indur Goklany has produced a brief report on the tremendous benefits of additional carbon dioxide in the atmosphere, largely attributable to the human use of fossil fuels. The report was published by the Global Warming Policy Foundation with a foreword by Freeman Dyson, the noted theoretical physicist from Princeton. In a recent interview Mr. Dyson said that he was a supporter of President Obama, but Mr. Obama has come out on the wrong side of the global warming/climate change issue and the effects of atmospheric carbon dioxide. In a recent interview Dyson expressed concern over the recent scientific concentration on global warming/climate change and said it is “not a scientific mystery but a human mystery. How does it happen that a whole generation of scientific experts is blind to the obvious facts [?]”

Goklany is a former US representative to the UN Intergovernmental Panel on Climate Change (IPCC) and author of the well-researched book The Improving State of the World: Why We’re Living Longer, Healthier, More Comfortable Lives on a Cleaner Planet (2007). Goklany’s new report provides independent confirmation of the findings by the Non-government International Panel on Climate Change (NIPCC), namely in the more comprehensive Climate Change Reconsidered II: Biological Impacts [2014].

Among his main conclusions Goklany finds:

· “Empirical data confirms that the biosphere’s productivity has increased by about 14% since 1982, in large part as a result of rising carbon dioxide levels.

· Thousands of scientific experiments indicate that increasing carbon dioxide concentrations in the air have contributed to increases in crop yields.

· Satellite evidence confirms that increasing carbon dioxide concentrations have also resulted in greater productivity of wild terrestrial ecosystems in all vegetation types.
