Appetite for Destruction: Why feeding China's 1.3 billion people could leave the rest of the world hungry.

Appetite for Destruction:  Why feeding China's 1.3 billion people could leave the rest of the world hungry. | Sustain Our Earth | Scoop.it

Beijing's food security policy is an uncharacteristically impractical choice from a usually pragmatic government. It is motivated by the psychological legacy of repeated, disastrous famines that scarred the Chinese public over the last 150 years, the most recent being the policy-induced famine during the Great Leap Forward that led to tens of millions of deaths in the late 1950s and early 1960s. Food is central to the national mindset, especially for the many Chinese alive today who have personally experienced crippling scarcity.

Natural Gas and Price Inceases | The Energy Collective

Natural Gas and Price Inceases | The Energy Collective | Sustain Our Earth | Scoop.it

There is a good reason for American nuclear energy professionals to learn more about the dynamics of the natural gas market. We have been told numerous times that cheap natural gas is making our technology less and less viable in the competitive market place. Natural gas (also known as methane) is a terrific product, but it has been promoted as being capable of supplying a much larger portion of our overall energy demand. That promotional effort is putting us all at risk of a severe hangover when the low price bubble bursts.

Irrigating Fields With Sunshine, The Sunflower Pump Is An Insipired Low-Cost Alternative To Diesel Pumps

Irrigating Fields With Sunshine, The Sunflower Pump Is An Insipired Low-Cost Alternative To Diesel Pumps | Sustain Our Earth | Scoop.it

Originally published on Ecopreneurist.

Sunflowers, sunbeams, and dry fields. The sun is shining and the fields need watering, what’s a farmer to do? Use his tired old back pumping water? Worse yet, use that smelly diesel fuel or petrol to pump some water? No, there is an alternative! Use the sunshine to pump the water. It just goes hand in hand — sunshine and watering are two parts of the same work day. When the fields need watering, there is plenty of sunshine. Renewable energy is ever-present.

Stephen Harper’s environment minister casts doubt on climate change

Stephen Harper’s environment minister casts doubt on climate change | Sustain Our Earth | Scoop.it

OTTAWA — Prime Minister Stephen Harper’s environment minister is casting doubt about scientific observations of melting summer sea ice in Canada’s north.

 

In a short televised interview on CTV’s daily political show, Power Play, Leona Aglukkaq suggested that scientific observations were not as important as the Harper government’s priorities in its new role as chair of a group of Arctic nations.

 

When asked whether the ice was melting in the Arctic, considered by climate scientists to be part of the evidence of global warming, Aglukkaq said there may or may not be changes underway.

PIRatE Lab's curator insight, October 5, 2013 5:30 AM

This increasing concern over the accounting/fate of the oil and dispersant is welcome, albeit a bit late in my opinion.  My group and others have tried to emphasize the true impact of the blowout would be on ecosystem-level properties in the mid and deep waters.

 

See:

Here is hoping that we can foster a moer holistic review of the hydrocarbon fate and effects from the 2010 disaster.

World’s Carbon Budget To Be Spent In Three Decades

World’s Carbon Budget To Be Spent In Three Decades | Sustain Our Earth | Scoop.it

The Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report (AR5) has delivered an overwhelming consensus that climate change impacts are accelerating, fueled by human-caused emissions. We may have just about 30 years left until the world’s carbon budget is spent if we want a likely chance of limiting warming to 2 degrees C. Breaching this limit would put the world at increased risk of forest fires, coral bleaching, higher sea level rise, and other dangerous impacts.

Alternative energy MFs racked up extremely robust gains in the past year. Returns range from a low of 16%, to a high of 64% for a mutual fund that is heavy into solar investments. ETFs also did well, but returns are much more variable. They range from a loss of 34% for a carbon ETF, to more than doubling of a solar ETF.

Postcard from the frontline: a Canadian family physician on peak oil

Postcard from the frontline:  a Canadian family physician on peak oil | Sustain Our Earth | Scoop.it

A Canadian family physician's take on peak energy, peak food and peak population: "I became aware of peak oil five years ago, and since then I have been struggling to integrate this knowledge into my medical practice and family life."...

 

When I first became peak oil aware, I used to ask the reps how their products were manufactured and what raw materials were used.  I soon found out that they have a fairly limited script for their presentations, and this is not part of the script.  None of them knew where their products came from.  They all promised to find out from their head office and let me know, but none of them ever did.  I suspect that most modern pharmaceuticals are manufactured from oil-based chemical feedstocks using processes which cannot be replicated outside a large chemical plant, which would make home-based production of essential pharmaceuticals like insulin almost impossible.

Residence Time and Prof Essenhigh

Residence Time and Prof Essenhigh | Sustain Our Earth | Scoop.it

Residence Time is something that crops up now and then in the denialist literature.

 

Essenhigh's argument is that residence time (which is the content divided by the outflow) is 750Gt divided 153.3Gt/y, which equates to ~5 years.  Therefore human contributions are irrelevant because the molecules of carbon dioxide that we put into theatmosphere are removed within 5 years.

 

What he ignores (though it’s equally clear in his own diagram) is that there is a net flow into the atmosphere of 2.2Gt/year.  It is this flow that would be absent without fossil fuels (and other activities like deforestation) and therefore is rightly attributed to man’s behaviour.

Allow me to make a simple analogy with a queue (this idea comes from Prof David MacKay’s [3] highly readable Sustainable Energy: Without The Hot Air, which is available for free on-line):
