From honeybeesandhelium blog
My second son was born two weeks ago, so I have and will have less time to blog. But precisely because of my sons I am more and more convinced that we have to raise the consciousness of every people in the world about the dangers of climate change and the ways to fight it, because it is possible, not easy, but possible to reduce our emissions and avoid a more extreme form of change.
The recent news about passing the 400 ppm of CO2 in the atmosphere has been another expected step in this process. It was a question of time and 400 is not much more than 397 but we are used to be moved by symbolic numbers and this is one of them, in fact, the accepted “secure ” co2 concentration has moved from 350 to 450 untill 550 ppm now. So 400 is significant.
It is not the magic number that changes everything as explained here, if there is a tipping point in climate change (difficult to know) most experts locate it higher, however it is important because it shows clearly that the show is going on in the wrong direction and it is useful to make everyone more conscious of that due to the media covering. So, the question is:
Will this child enjoy a reasonable climate and future because we acted while he was young or will he witness a mess caused by our inaction?
