I’ve just been up to Svalbard, in the high arctic, for a symposium on climate change. Here are some excerpts from a correspondent’s diary over at The Economist.
…How sustainable it is for 40-odd people to travel a very long way in order to attend yet another meeting on climate change is obviously open to debate. At the same time, old Arctic hands say that it is impossible to appreciate what is happening in the Arctic without at least some experience of being there, and there is no real way of proving them wrong. There’s also the possibility that the combination of people, topic, setting and isolation (because of the nature of some of the research Ny Alesund is a wi-fi, Bluetooth and mobile phone-free zone) will conjure new freshness into potentially tired discussions. Certainly it’s not an opportunity to turn down. [whole entry]
…Perched up above the last working Longyearbyen mine (“Mine 7”, which produces only enough coal as the town’s power station needs) two radio telescopes gaze up into the sky. One, like most such dishes, can swivel around. The other is fixed, looking almost straight up; built to study the aurora, rather than the stars, it can see most of what it needs by looking straight up the earth’s near-vertical magnetic field lines. When turned on, these radio telescopes use as much as 20% of the electricity generated from the coal that is being mined out of the ground beneath as they tickle the northern lights above, listening for faint echoes.

…The air is cool. The light is warm. The colours have changed in response to the sky. The soil, such as it is, seems darker, richer. The plants have taken on a fuller set of greens, mixed through with lichen orange and the persistent, almost-afterburn purple of saxifrage in summer flower, deeper the longer you look. Standing water, of which there is a lot, has turned sky-vault blue—except for that which forms the larger, more distant ponds, and reflects the mountains beyond. The fjord, by contrast, is lighter now than the puddles, almost milky. [whole entry]
…In the late afternoon (sun west by southwest, over the airstrip) the symposium took to the water, heading to the top of the fjord to look at the glaciers under clearing skies. Bijou icebergs floated almost stationary in the still water. A flock of kittiwakes, startled, flashed up from their station at the point where meltwater and seawater meet. Scientists talked of kelp and copepods. The ice at the end of the Kongsfjord towered above us. But less so than once it would have. Many of the other glaciers no longer reach the sea, retreating to their mountain lairs, folded moraines left behind them.
Studies of fjord-floor sediments show that the glaciers are further back now than they were when Vikings sailed to Iceland and Greenland (and, possibly, Svalbard, though if so they left no trace of their presence for their descendants other than disputable references in some sagas). It is possible they were this shrunken in the northern hemisphere’s early post-ice-age warmth, 8,000 years ago, but that is not certain.[whole entry]
…By the time the passengers for the third flight have been ferried out to the airstrip, perhaps a kilometre out of town, the top of Mt Zeppelin, at 474 metres, is in cloud, too, and snow is beginning to blow in from the northeast. The base’s radio telescope, part of a worldwide network that defines the absolute reference frame for GPS navigation, among other things, scans the now slate-like sky with a whirring creak. It is because of the dish’s sensitive measurements that wifi, bluetooth and mobile phones are banned in Ny Alesund. The Dornier turns up, we pile in, and the base quickly vanishes below us. It will be the last fixed wing flight out of Ny Alesund for a while. [whole entry]
