One day, some thirty years ago, as a six-year-old little girl, living in a European country, I thought it was so cold outside, and I thought it would be a “good deed” to leave the doors open, so the warmth of our central-heated house could compensate a little the too cold world outside.

My mother quickly came over, and explained to me that not only this was bad for family economics, but also it would contribute to something ‘she had read about’, which was the greenhouse effect, and that actually it could be the case that the world was warming up, which could have several negative effects…

My mother is somebody who would read about this kind of stuff, who would get informed. The mothers of my classmates hadn’t heard of climate change at that time. Well, that was understandable, the problem was only incipiently known, temperatures had risen only slightly in the last century or so, arctic ice extent was relatively stable, and no major climate disasters had happened.

How we live the climate change reality now

Now, thirty years later, even my 5-year old daughter knows about climate change, we got all used to hearing about climate disasters, and the local effects of climate change became part of the small talk of the people. We now live in a world with only half of the summer ice extent of that of the world where the 6-year old me lived.

But by now, nobody gets really shocked about climate change news anymore. At what point this little me got used to the effects of global warming? To the continuous news on more “natural disasters”, which are now proven not to be natural disasters but man-made anthropogenic-climate disasters? To the news on once again increasing green house gas emissions? To the news that once again we trespassed a climatological record? More »

Scientists have the picture clear. James Hansen et al, in “The Case for Young People and Nature: A Path to a Healthy, Natural, Prosperous Future”,  explain us very clearly that the impact of the actual 0,8°C global warming is causing already several global warming reinforcing mechanisms, like ice melting, ocean acidification, expansion of hot dry subtropical climate belts, etc.

They warn us, with clear scientific arguments, that sustained greenhouse gas (GHG) concentrations of more than 350 parts per million (ppm) will lead to very dangerous climate disruption. We now live in a world with 390 ppm.

In 1992, time when the climate convention was agreed upon, an objective was set: “The ultimate objective of this Convention is to achieve stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.” At that time, the GHG concentration in the atmosphere was of 354 ppm.
