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 and his colleagues, the 0.58… Continue reading NASA study backs 350 ppm objective

Climate change is not a technological issue

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… Continue reading Climate change is not a technological issue

A single solution for three problems

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).

However, we have recently seen that the least developed nations and many island nations in the Pacific Ocean call for… Continue reading 2°C of temperatures increase might be too much

Time to focus on 350

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 but it is still time… Continue reading Time to focus on 350
