Given how Humankind keeps on spewing dozens of billion tonnes of carbon dioxide each year, this was expected : carbon dioxide concentration have reached 400 parts per million. While this may sound mundane to most people, this is a real event, and one that could have dire consequences. Last time […]

Carbon dioxide concentration reaches 400 ppm

350.org rally in Washington

This Sunday took place in the United States of America the largest climate rally ever (in the country) up to 40,000 people walked peacefully, chanted and danced in Washington DC. Other rallies were organized in many other states. All had the same message : they were asking President Obama to […]

The biggest US climate rally to date

A thousand billion dollars, or if you prefer, a trillion dollar. This is the staggering amount of money you and I are handing out to Big Fossil fuel companies each year by the mean of governmental subsidies. At a time of climate weirding and warming, massive pollutions of our air, […]

It is high time to end fossil fuels subsidies

A new study by the NASA is bringing more credence to the fact we need to go back to carbon dioxide concentration of 350 parts per million.  This will hopefully be a huge boost to the 350.org campaign. As Climate Progress reported : ” According to calculations conducted by Hansen […]

NASA study backs 350 ppm objective


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 […]

Climate change is not a technological issue

Yesterday took place around the world 7,700 gatherings in over 180 countries to urge governments to embrace 350 : lowering the amount of carbon dioxide to 350 ppm (today’s levels are at 388). I already stated that we are facing a triple crisis with massive unemployment, climate change and decreasing […]

A single solution for three problems

Today is special as 350 is organizing the International Day of Climate Action. In 181 countries over 5200 events are taking place for the most widespread day of environmental action in the planet’s history. 350 is “ an international campaign dedicated to building a movement to unite the world around […]

International Day of Climate Action


It is widely known and agreed upon within the scientific community and our elected representatives that Mankind has to limit the increase of temperatures to two degrees Celsius (3.6°F) by 2100 compared to 1850 levels. However, we have recently seen that the least developed nations and many island nations in […]

2°C of temperatures increase might be too much


Since this is my 350th post on elrst.com, I thought it is the perfect timing to focus on the global initiative due to mitigate climate change called 350. This number refers to the amount of carbon dioxide parts per million (PPM) we shouldn’t go over. We are currently at 387 […]

Time to focus on 350
