A good start to the working week! I'm in Botswana with two colleagues to measure underwater sound (both boat noise & animals) in the Chobe river. But before it all started, I did get a run in and found this warning sign. No elephants were seen on the run, but we did see one on the river bank yday.

Today's science on the Botswana-Namibia border: We've been mapping out the river bed, measuring the water, and listening (underwater) to boats, hippos and many mysterious fish. And mythbusting the local assertion that some parts of this waterway are 40 metres deep. We are such spoilsports...

Elephants! What a lovely end to the working day. We collected our last hydrophone and made the last measurements upstream, and then on the way back SO MANY elephants had come down to the river to cool off. Do listen with the sound on - there's proper trumpetting. 🐘🐘🐘🐘

NEW: A mega snow storm - SNOWPOCALYPSE - recently hit residents of Juneau, Alaska.
I spoke to heat pump owners there to find out how they coped. Their heat pumps did great, apparently!

Juneau's severest winter storm in decades was no match for some air-to-air heat pumps

The mass of CO₂ humans put into the atmosphere in 2025 is 4x the mass of all plastic humans have ever produced.
Humans have emitted 2750 gigatons of CO2 since the industrial revolution from burning fossil fuels and land use change. To put this in perspective, this is more than the (dry) mass of all living things on earth and everything humans have ever built combined:

It's a huge honour to receive the Spilhaus award from the American Geophysical Union, the big US earth science organisation. I joined their glitzy New Orleans award ceremony yesterday online & was very struck by this statement at the start:

Wow. I did not know that Alfred Russell Wallace (co-discoverer of evolution by natural selection) wrote a book in 1904 about the biological potential for life on other planets, and I've just found this extraordinary paragraph setting out the insanity of atmospheric pollution [1/3]. In 1904!
![But the sketch I have here attempted to give of its varied functions shows us that it is really a most complex structure, a wonderful piece of machinery, as[ 259] it were, which in its various component gases, its actions and reactions upon the water and the land, its production of electrical discharges, and its furnishing the elements from which the whole fabric of organic life is composed and perpetually renewed, may be truly considered to be the very source and foundation of life itself. This is seen, not only in the fact of our absolute dependence upon it every minute of our lives, but in the terrible effects produced by even a slight degree of impurity in this vital element. Yet it is among those nations that claim to be the most civilised, those that profess to be guided by a knowledge of the laws of nature, those that most glory in the advance of science, that we find the greatest apathy, the greatest recklessness, in continually rendering impure this all-important necessary of life, to such a degree that the health of the larger portion of their populations is injured and their vitality lowered, by conditions which compel them to breathe more or less foul and impure air for the greater part of their lives. The huge and ever-increasing cities, the vast manufacturing towns belching forth smoke and poisonous gases, with the crowded dwellings, where millions are forced to live under the most terrible insanitary conditions, are the witnesses to this criminal apathy, this incredible recklessness and inhumanity.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:2g72wvrmzdfakrjq56d3lddj/bafkreidgfp3g5erh7m3rdhzqvar2th65nqj72arwtpxrzak4yvtepmshba@jpeg)

Love this
In 2014 Dutch scientists left a hamster wheel outside, to see if wild animals would use it like their domesticated counterparts.
The answer: hell yes! 734 visits from wild mice - plus rats, shrews, slugs ("running" being subjective here) & even frogs and snails.
The apparent reason: fun. Just fun.
