Atmospheric Carbon Dioxide passed a significant milestone at the Hawaiian monitoring station that has been recording these things longer than anywhere else on the planet. I did a piece for radio where you can hear the officials from Mauna Loa Observatory analyse the significance of this in their own words.
There is little a generalist like me can add to the Climate Change debate that hasn’t already been argued, but allow me to share this graph with you, which you mightn’t have seen.
It charts efforts at a political level to check our carbon emissions and maps them against the unstoppable progress of atmospheric CO2 through the previously unthinkable threshold of 400 molecules for every million molecules of air.
Or rather it charts the redundancy of those political efforts. It is a crude index, but an eloquent way of saying that Carbon Emissions Trading lies in tatters; austerity has brought coal back into fashion with a vengeance; and governments all over thew world are letting themselves off the hook of their commitments.
I could go on, but this is a scientific debate and the scientists say it much better than journalists – so listen here to the significance of another signpost now in the rear view mirror
