'We’re going into very new territory' explained the US National Oceanographic and Atmospheric Administration as they report that the world is hurtling towards global concentrations of carbon dioxide tipping over the 400 parts per million milestone.
The Southern Hemisphere atmospheric measuring station in Australia is poised at 399.9ppm while the station in the Northern Hemisphere went above 400ppm in 2013.
'We wouldn’t have expected to reach the 400ppm mark so early' said David Etheridge, an atmospheric scientist from the CSIRO, which runs the Australian measuring station, 'CO2 Concentrations are growing fast as warmer land areas release carbon. So we would have otherwise expected it to happen later in the year. No matter what the world’s emissions are now, we can decrease growth but we can’t decrease the concentration'.
This year has seen record hot global ocean temperatures, air surface temperatures has been breaking annual and monthly temperature records and in a great bit of understatement, the NOAA signed of with a sigh of 'It’s pretty ugly when you look at it'.
Decades of warnings have gone unheeded so it may be that we have carelessly crossed a tipping point so it's a case of it may be too late and our own foolishness has bought natures cataclysm upon us so time to limit the effects of devastating runaway global warming with lessons on how to survive it.
If that includes constructing huge biospheres or shifting our cities underground then we should make the move towards investigating the options we have so that the population of the Earth can survive our own absurdity.
