Yearly Archives: 2009


This is time for me to present my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). As always, this month was packed with beautiful images. It was as always difficult to select just ten. For the last post of the year (and of the decade) […]

Great astrophotographies – December 2009


I am committed since January 2007 to bring you each month a selection of thelatest headlines and best researches on sustainable development, climate change and the world energy sector. However, I don’t blog as much as I would like to and generally write around 25 posts per month. However, many […]

Worth an article – my December 2009 tweets


This is ” the latest inconvenient truth about climate change ” : Nature absorbs less and less carbon dioxide and this as we keep on increasing our emissions. The Washington Post recently published an interesting article on this. Both forests and oceans absorb carbon dioxide and act as carbon sinks. This […]

Carbon sinks are becoming less efficient

Since I read Collapse back to 2007 I have been an advocate of both stopping deforestation and reforesting as both are needed to stop soil erosion in a local scale and stop climate change on a global scale. It seems the Copenhagen climate conference was not a complete failure as […]

Soon a deal to end deforestation


The Copenhagen climate conference failed in preparing the future of the Kyoto Protocol. This is even more enraging as at first positive signs kept on piling : the United States and  many developing nations proclamed they would act. I saw it coming as still too many are elected representatives around the world that […]

The huge failure of the Copenhagen conference

This was the title of an article on Dot Earth, as I read the associated New York Times article in Le Figaro as this newspaper now proposes a selection of the best articles from the NYT. The article is about how natural gas – and methane – is leaking through […]

Keeping natural gas in pipelines, not air


The World Bank via its Clean Technology Fund is investing $750 million (522 million euros) in eleven concentrating solar plants in the Middle East and North Africa region. This is due to spur additional investments worth $4.85 billion. These projects are due to add nearly a gigawatt of capacity to […]

World Bank funds solar projects in North Africa


We had reason to be optimistic on the Copenhagen Climate Conference as the United States unveiled on the first day a plan that will allow its Environmental Protection Agency to act on greenhouse gases emissions. Among the gases that will be regulated are carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons […]

EPA to regulate greenhouse gases emissions


As the year 2009 is ending the World Meterological Organization reveiled in a report that this decade was the warmest ever recorded. This happens as each passing decade is warmer than the previous one. What disqualifies any natural phenomenon as an explanation is the speed of the warming and the […]

2000-2009 : the warmest decade ever

Many people think that the current Copenhagen climate conference is about saving the planet. I believe this not true as we are just trying to save ourselves from our own folly. Our planet – whom you may refer to as Gaïa – will still be there long after we are […]

It’s not about saving the planet, but ourselves

While some magazines print sensationalist articles, some other prefer to carry out real research with real facts and figures. New Scientist indeed published an interesting article on what they call extreme – or unconventional – oil. Understanding that peak oil is either near or already arrived we can either burn […]

Extreme oil anyone ?


While in the train going to Paris to attend the Green Job forum I read an interesting article on how banking on trees could enable us to fight off climate change and give money to enable developing nations to protect their forests. The United Nations REDD program – Reducing Emissions […]
