The further adventures of batgirl…

I wrote this series of comics to amuse and inform my kids while I was on fieldwork a few years ago. It turned out to be quite a success and my kids classes both read the Danish versions at their school.

Last year I started https://icemangoeshome.wordpress.com/more-arctic-adventures/ the further adventures of batgirl on the ice with her new friends the Lego scientists and a couple of stowaways.. but last year’s season was extremely busy and I never managed to finish it.

I asked yesterday on mastodon if I should do another this year, and the only feedback I got was I should try to finish the one I started last year. So maybe that’s what I’ll try to do. It’s always challenging fitting around field tasks though so no promises.

This is just a quick post from the airport: you’ve been warned, bat girls and her friends are on their way back with a new season!

A New Arctic Adventure

Natural cycles: oceans and glaciers and volcanoes…

Reblogging this brilliant piece in Ars Technica* with thanks to Andrew Dessler on Mastodon for sharing.

It’s a really thorough introduction to the climate system and all the natural sources of climate variability and cycles of change, including links to sources. Well worth taking your time over with a morning cup of tea and probably I’ll assign it as an introduction text for BSc students (and management) on the big picture of climate change.

I also love it for the introduction where multiple eminent and respected scientists are asked what they’d buy with all the dollars they’d have if they were given one dollar every time someone asked them about “natural climate cycles”. As you might expect, the answers range from heat pumps and solar panels to new bicycles and a time machine.

Not sure what I’d use it to pay for, possibly a new postdoc position to work on snow and ice processes?

Now that the doubt is out the way, please go and also read this wonderful piece by Rebecca Solnit in the Washington Post about why and how reducing fossil fuel use might lead to abundance and joy and enhanced quality of life (hat tip to David Ho also on mastodon for this one).

*as an aside: I haven’t read Ars Technica in ages. And it’s funny because I remember that when I first started on twitter way back in 2010 there were *a lot* of good articles shared from there on the bird site. Somehow they either were not shared or got suppressed and I stopped seeing them. I’m not sure if that was due to the algorithm or different people I was following. One of the nice things about mastodon is that without an algorithm (and crucially, by following *a lot* of people!) there is a chance to see a much greater diversity of different media. It feels a bit like seeing a different internet, outside the standard walled garden.

Signs of Spring

Currently, I’m very busy getting ready with colleagues to travel to Greenland next week. We have an extremely full programme of fieldwork activities covering oceanography, biology, sea ice, snow and glacier processes as part of our NCKF work. More on these no doubt in a future post…

Yesterday, one of my ace DMI colleagues (without whom most of the work we plan would definitely not happen) shared the first optical satellite image of the area this year – taken by ESA’s Sentinel 2 (a truly astonishing source of free imagery and everone should know about it). Because the area is very far north, it has been in the Polar night until now so we have been reliant on the ESA Sentinel 1 imagery based on radar.

First Sentinel-2 optical satellite image of the year downloaded from Sentinel Hub’s EO Browser today. Processing with Sentinel Hubs optimised natural colour filter has introduced some artefacts, notable the brigh white patches which probably represent areas of shadow due to the low solar angle. The area is blanketed in thin cloud and only parts of the glaciers, sea ice and icebergs are clearly visibe.

It’s a wonderful thing to see the first satellite image of Spring, akin to other signs like the first cuckoo (in the UK), the first peewit egg (in the Netherlands), and the timing of the cherry blossom in Kyoto.

The first lapwing (peewit) egg of the year was traditionally presented to the Dutch monarch – these days, given the

There was recently a very illuminating thread on phenology on mastodon in reply to a query by Pauline von Hellerman where the Diagram Monkey John Kennedy pointed out the existence of the Pan European Phenology network – not something I was aware of before (though I’d suspected it’s existence) – and who have all sorts of interesting data.

Where biology is clearly showing us earlier springs due to climate change, the date of the first optical image is unlikely to change any time soon due to climate change.

A newer updated version of the Economist’s cherry blossom flowering date plot provided by Datagraver after I posted the old one. See: https://mastodon.social/@Datagraver/110021046678442071

Nor are species assemblages (it’s not quite certain that it’s the same variety of cherry blossom for the whole 1200 year period), or biodiversity losses (the cuckoo is down 65% since the early 1980s alone in the UK, and heaven knows it was not particularly common then) likely to affect it. Not to mention human behaviour changes, the lapwing has gone from being a common agricultural bird to near threatened over the same period, which probably also affects the reliability of that data.

Of course, quite a bit of what you might call bulk phenology can be done by satellite too now…

As for Qaanaaq, there is not much in the way of biological phenology, but a compilation and analysis of data on sea ice cover and thickness over the last 60 years would probably be as instructive. Do get in touch if you’re interested in doing this as a student project…

How climbing made me a better scientist

Non-exhaustive list of (occasionally erroneous) reasons why climbing makes me science better (and explaining inter alia why I interview awfully). Prompted by this stupid tweet1: How can being a rock climber (or a baker, or a stand-up comedian, or…) make you a better researcher? Scientists share their thoughts (and their hobbies) in this #NextGenSci: https://t.co/v8JoesyzJ2 […]
