Yes, you read that right. With all the fuss about renewable energies like solar, wind, hydro, geothermal and so on, the energy source that saw its use increase the most recently is the dirtiest of them all : coal. As the BP Statistical Review 2012 reports : ” Coal was again the fastest growing fossil …
Do you remember my enthusiastic post last year on a US “cap-and-invest” program, the Regional Greenhouse Gas Initiative (or RGGI) ? Well, it seems that it worked really well. To Climate Progress, the power sector of the nine participating states have slashed its emissions by 23 percent in only three years thanks to the decreased …
This is historical : carbon dioxide concentration has reached in several places over the arctic a concentration of 400 parts per million. This doesn’t seem to be much, but pre-industrial levels were of 280 ppm. As you might remember, the safe level is considered by the scientific community to be at 350 ppm. CO2 concentration …
According to the latest report by the Club of Rome, the average global temperature could increase by two degrees Celsius if nothing were done beforehand. Such an increase is seen a dangerous as it would enable positive feedback mechanisms – such as drying up of the Amazon or melting permafrost in Siberia – to be …
As the situation is getting more and more desperate and climate gets weirder, global greenhouse gases emissions keep on increasing globally. As the International Energy Agency stated last week : ” Global carbon-dioxide (CO2) emissions from fossil-fuel combustion reached a record high of 31.6 gigatonnes (Gt) in 2011, according to preliminary estimates from the International …
I had written about this very topic last month. To the New York Times green blog : ” A new scientific paper suggests that the ocean is acidifying at a rate that is many times faster than at any time in the past 300 million years. “ ” The change is occurring so rapidly that it raises …
Ocean acidification at its highest in million years Read More »
If climate change, rising sea levels and the threats to global peace and food production weren’t enough to you, here is another reason to fight carbon dioxide : ocean acidification. To Mongabay : ” Emissions of carbon over the last two centuries have raised the acidity of the oceans to the highest levels in 21,000 …

As the Wall Street Journal notes : ” Australia’s controversial plan to introduce a tax on carbon emissions cleared a major political hurdle Wednesday, securing the expected approval of the country’s lower legislative house.” ” The package to introduce a price on carbon pollution and encourage investment in clean and renewable energy narrowly passed at …
I have been knowing it for years as I read Jean-Marc Jancovici‘s books : current technologies can solve our climate and energy issues. This is corroborated by a joint statement by eleven of the world’s largest engineering organisations. To Climate Progress : “The technology needed to cut the world’s greenhouse gas emissions by 85% by …
CleanTechies gives us some data on something absolutely terrible for a global future : ” Global emissions of carbon dioxide (CO2) increased by 45 % between 1990 and 2010, and reached an all-time high of 33 billion tons in 2010. “ ” Increased energy efficiency, nuclear energy and the growing contribution of renewable energy are …
