Perspective, Giddiness and Magic

This wonderful video was shot a few days ago in New Zealand. It shows the Moon rising in real-time - this is not a time lapse – over Mount Victoria Lookout in Wellington, N.Z.

Take four minutes out of your day to watch this and wonder at the dance of the planetary spheres in the dark of space, and sense how small we are. Feel giddy!

This is how it was. What’s next? Feeling lucky, punks?

Calculated from NASA’s (click for more info) “Five-Year Average Global Temperature Anomalies from 1880 to 2010” and animated. Even a trainee climate scientist has been surprised at how fast things speed up right near the last couple of decades.You need to be at least a little bit scientifically literate to realise why anomalies are way more important to show the trend rather than absolute temperatures – a distinction which many cherry picking denialists, with their “it’s really cold here, so we must be in a cooling trend” garbage thinking cannot get clear in their heads but still, even they must get it, surely?

Note how the warming anomalies are by far the greatest in the Arctic zone where all the permafrost and Northern sea ice is. This is happening far faster than the last full IPCC digest of the science delineated in 2007. Those models did not take this faster heating and consequently faster rate of shrinkage of the ice into account in their models. Neither did they consider the release of methane from the permafrost nor the entrained carbon.

To those complacent enough to comfort themselves with the belief that the models’ predictions are wrong I say – you were right! Sort of. The predictions of the models were wrong – they did not take enough into account – but they were wrong in a bad way. Things are worse than previously suspected. Read again my post of the 19th February entitled  We’re ***’ed (We’re hosed…) which is about melting permafrost. I quoted Greg Craven who spoke recently at the AGU (American Geophysical Union):

AGU rattled me to the core because my worst-case fears were not just confirmed, but exceeded (I found four paleoclimatologists who admitted to making plans for survival retreats), and my last hope–for the scientific community to enter the public debate–was completely dashed.

I’ve since found out directly from Greg that the full story is that, of those he spoke to, he found four who would admit to this but they also confirmed that “many” more that they knew were doing the same.
