Author Says Soil Is Key To Addressing Effects of Climate Change

In 2013 the United Nations declared Dec. 5 to be World Soil Day, a recognition of the significance of healthy soil in both improving food security and nutrition, and mitigating the effects of climate change, including drought, flood, soil erosion and sea level rise. This year the U.N. held a conference at its New York headquarters on the theme of “caring for the planet starts from the ground.”

Didi Pershouse, founder of the Center for Sustainable Medicine in Thetford and author of The Ecology of Care, and the downloadable PDF which was released online in August, was one of five panelists invited to speak at this year’s conference.



How Technology Hijacks People’s Minds — from a Magician and Google’s Design Ethicist

I’m an expert on how technology hijacks our psychological vulnerabilities. That’s why I spent the last three years as Google’s Design Ethicist caring about how to design things in a way that defends a billion people’s minds from getting hijacked.

When using technology, we often focus optimisticallyon all the things it does for us. But I want you to show you where it might do the opposite.

Where does technology exploit our minds weaknesses?

Greater future global warming inferred from Earth’s recent energy budget

This is an academic study.


Climate models provide the principal means of projecting global warming over the remainder of the twenty-first century but modelled estimates of warming vary by a factor of approximately two even under the same radiative forcing scenarios. Across-model relationships between currently observable attributes of the climate system and the simulated magnitude of future warming have the potential to inform projections. Here we show that robust across-model relationships exist between the global spatial patterns of several fundamental attributes of Earth’s top-of-atmosphere energy budget and the magnitude of projected global warming. When we constrain the model projections with observations, we obtain greater means and narrower ranges of future global warming across the major radiative forcing scenarios, in general. In particular, we find that the observationally informed warming projection for the end of the twenty-first century for the steepest radiative forcing scenario is about 15 per cent warmer (+0.5 degrees Celsius) with a reduction of about a third in the two-standard-deviation spread (−1.2 degrees Celsius) relative to the raw model projections reported by the Intergovernmental Panel on Climate Change. Our results suggest that achieving any given global temperature stabilization target will require steeper greenhouse gas emissions reductions than previously calculated.

Most Dire Climate Change Predictions, Warns New Study, Are Also the Most Accurate

New research shows emissions must go down every year starting in 2020 to prevent dangerous warming of planet



If assembled, innovations from three spheres of economic activity – those using natural ecosystems, social and collaborative innovation, and efficient technology – enter into symbiotic relationship.

Together, we can create a new economic paradigm which can amplify our positive impact on the planet, while renewing global prosperity

Soil Power! The Dirty Way to a Green Planet

The earth possesses five major pools of carbon. Of those pools, the atmosphere is already overloaded with the stuff; the oceans are turning acidic as they become saturated with it; the forests are diminishing; and underground fossil fuel reserves are being emptied. That leaves soil as the most likely repository for immense quantities of carbon.

Now scientists are documenting how sequestering carbon in soil can produce a double dividend: It reduces climate change by extracting carbon from the atmosphere, and it restores the health of degraded soil and increases agricultural yields. Many scientists and farmers believe the emerging understanding of soil’s role in climate stability and agricultural productivity will prompt a paradigm shift in agriculture, triggering the abandonment of conventional practices like tillage, crop residue removal, mono-cropping, excessive grazing and blanket use of chemical fertilizer and pesticide. Even cattle, usually considered climate change culprits because they belch at least 25 gallons of methane a day, are being studied as a potential part of the climate change solution because of their role in naturally fertilizing soil and cycling nutrients.
