The Quiet Realization of Ivan Illich's Ideas in the Contemporary Commons Movement

The Quiet Realization of Ivan Illich's Ideas in the Contemporary Commons Movement | Sustain Our Earth | Scoop.it

" It’s important to stress that the commons is not a resource.  It’s a resource plus a community plus that community’s particular rules and norms for managing the resource.  You could say that the commons is a socio-ecological-political-cultural paradigm and worldview."

Os chineses dão um jeito para tudo, inclusive para solucionar o problema de acúmulo de lixo no país e ainda incentivar a utilização do transporte público, ajudando na diminuição do trânsito de carros nas ruas que emitem grandes quantidades de CO2 por dia. Em duas estações de metrô em Pequim, Jinsong e Shaoyaoju, máquinas coletoras fazem mais do que estocar lixo reciclável, elas geraram crédito para a compra das passagens de transporte em troca de simples garrafas de plástico.

As máquinas coletoras recebem as garrafas PET que seriam jogadas em vias públicas e troca por créditos na compra do vale transporte. Os valores podem variar, dependendo do tipo e do tamanho da garrafa descartada corretamente. Cada embalagem colocada no equipamento vale entre US$ 0,15 e US$ 0,50. Com 15 garrafas, por exemplo, é possível se deslocar por todas as oito linhas e as 105 estações disponíveis.

O objetivo da iniciativa também é estimular os moradores da capital chinesa a utilizarem o transporte público e diminuir o índice de poluição do ar de quem decide se deslocar de carro. O projeto surgiu para tentar melhorar problemas da China com transporte, lixo e poluição. O governo também quer reciclar 70% dos resíduos até 2015.

See the Huge Rim Fire Move Into Yosemite in These Views From Space - Wired Science

See the Huge Rim Fire Move Into Yosemite in These Views From Space - Wired Science | Sustain Our Earth | Scoop.it

The past four days have seen one of California’s biggest fires in history burning its way toward one of the country’s most beloved national parks. The Rim fire has burned around 160,000 acres so far, including 21,000 acres inside the park.

The images above were taken each night from August 23 to August 26 by NASA’s Suomi NPP satellite. The size of the fire can be clearly seen (especially when compared to familiar nearby cities like Las Vegas, Reno and San Francisco as well as Lake Tahoe in this bigger image, taken by the same satellite).

Humans’ complicity in climate change can’t be ignored

Humans’ complicity in climate change can’t be ignored | Sustain Our Earth | Scoop.it

NEXT MONTH, the international arbiter of the scientific consensus on global warmingwill release its latest evaluation of the state of the research. A few will dismiss the Intergovernmental Panel on Climate Change’s (IPCC) findings as overwrought alarmism. But a draft leaked to reporters last week indicates that, for most people, the report will serve as another stern warning about the risks of continuing to pump carbon dioxide into the air.

 

The scientists are set to claim that the increasing amount of greenhouse gases that humans have emitted into the atmosphere has almost certainly been the chief driver of the warming of the planet over the past half-century, a finding to which they ascribe 95 percent confidence. That’s the level of likelihood researchers typically consider robust enough to justify drawing very strong conclusions.

TEDxWarwick - David MacKay - How the Laws of Physics Constrain Our Sustainable Energy Options

Department of Climate Change Chief Scientific Advisor, Professor David MacKay FRS, is responsible for ensuring the best science and engineering advice underpins DECC's policy and decision-making.

 

 

If you like this, there is an hour-long presentation with much more detail at: http://www.youtube.com/watch?v=GFosQtEqzSE

 

From his book about the same subject, http://www.withouthotair.com/

"Sustainable Energy - without the hot air" presents the numbers that are needed to answer these questions: How huge are Britain's renewable resources, compared with our current energy consumption? How big do renewable energy facilities have to be, to make a significant contribution? How big would our energy consumption be if we adopted strong efficiency measures? Which efficiency measures offer big savings, and which offer only 5 or 10%? Do new much-hyped technologies such as hydrogen or electric cars reduce energy consumption, or do they actually make our energy problem worse?

Daniel LaLiberte's curator insight, August 25, 2013 3:21 PM

MacKay focuses on the energy density of various energy alternatives, as well as how much more efficient we could hope to be to avoid consuming energy in the first place.  

 

Interesting and relevant, but what he presents is misleading.  It is a worthwhile comparison to make, but it needs to be done fairly.  Here is a good critique: http://chrisvernon.co.uk/2011/10/a-lot-of-hot-air-david-mackay-fudges-the-figures-in-favour-of-nuclear-power/

 

In particular, wind energy turbines don't use up the land area required, but only occupy about 5% of the land, leaving the rest for other things, including, say, solar energy collectors on top of roofs, which may be on top of spaces used for other purposes.  On the other hand the energy density of nuclear power needs to consider the entire cost of all the externalities as well.

WINNIPEG – The humidex in southern Manitoba will climb above 40 this afternoon, Environment Canada warns.

The humidex in southern Manitoba will climb above 40 this afternoon, Environment Canada warns.

A humidex higher than 40 can cause great discomfort and people should avoid exertion, Environment Canada says.

The humidex is a combined measure of humidity and temperature that reflects how hot the air feels, much the way windchill factors in wind to calculate how cold the air feels.

“An extremely high humidex reading can be defined as one that is over 40. In such conditions, all unnecessary activity should be curtailed,” the Environment Canada website says.

“If working outdoors is an absolute necessity, drink plenty of liquids and take frequent rest breaks.”

Extremely high humidex readings are rare in Canada, except in the southern regions of Ontario, Manitoba and Quebec, Environment Canada says.

China's legislators support renewable energy|Green China|chinadaily.com.cn

China's legislators on Monday called for greater support for the development of renewable energy industry which is facing obstacles in planning, purchase system, subsidies and technology.

 

Development of renewable energy must be a priority, with clear goals, as China is suffering poor energy structure, environmental pollution and ecological degradation, said Chen Changzhi, vice chairman of the Standing Committee of the National People's Congress, the top legislative body.

 

Development of renewable energy has contributed to China's economic and social development and improved people's lives, said Chen.

Congressman Says It’s ‘Arrogant’ To Believe In Man-Made Climate Change

Congressman Says It’s ‘Arrogant’ To Believe In Man-Made Climate Change | Sustain Our Earth | Scoop.it

Rep. Todd Rokita (R-IN) said that humans are not responsible for climate change, and that it is “arrogant” to think they could be.


“I think it’s arrogant that we think as people that we can somehow change the climate of the whole earth when science is telling us that there’s a cycle to all this,” he said. “And that cycle was occurring before the industrial revolution and I suspect will occur way into the future.”


By training, Rokita is a lawyer, so he is not actually qualified to scientifically assess the earth’s warming and cooling patterns. Of the climate scientists who have made a career of doing just that, 97 percent agree that climate change is real, and that humans are contributing to it.

SustainOurEarth's insight:

I think he is arrogant (and a little ignorant) if he thinks that we as people somehow cannot change world climate. What is happening now is something that hasn't happened in any previous climate cycles. 

 

Of course he gets paid a lot of money by the fossil fuel industry to say what he says.
