Global warming and the future of New Zealand

It’s been snowing most of the day chez Hot Topic, so any chance I may have had of viewing the transit of Venus across the sun earlier today was lost in a haze of snowflakes and cloud. However, thanks to the fact that the sun provides the energy that drives the climate system, I can justify posting this wonderful NASA video, produced by NASA’s Solar Dynamics Observatory. More imagery here. Breathtaking, I hope you’ll agree.
While Britain celebrates (Monarchists should not click on that link, be warned) its Queen’s Diamond Jubilee, and New Zealand hibernates on her birthday (which, of course, it isn’t), the planet has hit a notable milestone on its rapid transition to a new climate state. From way up in the Arctic, where the early summer melt is in full swing (click on the thumbnail to see more), NOAA reports that:
The concentration of carbon dioxide in the atmosphere of Barrow, Alaska, reached 400 parts per million (ppm) this spring, according to NOAA measurements, the first time a monthly average measurement for the greenhouse gas attained the 400 ppm mark in a remote location.
And it won’t be long before the rest of us get there:
“The northern sites in our monitoring network tell us what is coming soon to the globe as a whole,” said Pieter Tans, an atmospheric scientist with NOAA’s Earth System Research Laboratory (ESRL) in Boulder, Colo. “We will likely see global average CO2 concentrations reach 400 ppm about 2016.”
I knew that climate scientists were on the receiving end of some nasty emails, but it was still a shock to read James Hansen’s recent communication, in the course of which he gives a sample of the emails that he’d had in just the one week. They’re a dismal example of the unfettered rage which marks at least some sectors of the denialist world. Imagine receiving this sort of thing in your mail not just on the odd occasion but regularly:
- You rework your temperature data sets every time Mother nature proves you wrong, in an effort to force Her to agree with your ill conceived ideas about energy and nature. You, in fact, are the one committing crimes against humanity by lying, conniving, and concealing the truth about climate change on our world.
- What a pile of nonsense, Hansen. You take money and junkets hand over fist from people who pay you to mouth off trash like that. You aren’t exactly “forthcoming” about the “sources and amounts” of your graft – I mean, “gifts.” You ought to be ashamed of yourself,
- You sir are a walking crime against humanity and you know exactly why. You lie constantly about man-made global warming.
- You are not a scientist by any stretch of the imagination. You are a global warming shill and a con-artist.
- Are you some kind of lunatic??
And those are just my extracts from his selection from a week’s haul.

NASA’s IceBridge operation for this Antarctic summer has discovered that the Pine Island Glacier is in the process of calving a massive iceberg — 880 square kilometres of the floating glacier tongue is about to go floatabout, leaving the glacier snout shorter than any time since its position was first recorded in the 1940s. The crack was first spotted by a flight on October 14, and surveyed during a flight on the 28th — featured in the video above. NASA’s Earth Observatory has more pictures and commentary, and there’s a background piece for the video at the NASA IceBridge news page.

If you watch nothing else today, take the time to look at this spectacular movie of an aurora australis taken by the International Space Station on September 17, and made available by NASA’s Earth Observatory a couple of days ago. Not really climate-related, unless you’re into solar/climate linkages, but posted because the images are spectacular. And it is an atmospheric phenomenon…
