Those who patiently tolerate my posts may wonder about my preoccupation with small details in nature/objects/textures Well there is the intrinsic aesthetic & beauty BUT mainly - looking at the small helps me cope with facing the - at times seemingly impossible - big issues

🌍 Berkeley Earth’s 2025 Global Temperature Report is out.
2025 was the 3rd warmest year on record. Annual global temperature reached 1.44 ± 0.09°C above the pre-industrial baseline; 770 million people experienced locally record-warm annual conditions.

Global Temperature Report for 2025 - Berkeley Earth

2025 was the 3rd warmest year on Earth since direct observations began, and recent warming appears to be moving faster than expected.

Iceberg A-23A first broke off the Filchner Ice Shelf in 1986. NASA EO recently shared what's left, "waterlogged berg on December 26, 2025, extensive pools of blue meltwater were visible on its surface" and still one of the largest in the ocean. More at science.nasa.gov/earth/earth-...

Globally, no single day in 2025 was cooler than its 1991-2020 average.

A lightening visit to Cambridge
- you cannot imagine the joy these gave to someone escaping the snow, ice, cold and dark of Helsinki 😀

🌊New paper🐚 Seabed status varied strongly across Europe: the Black, Baltic, and Aegean–Levantine Seas generally showed high seabed community status, while the Western, Central, Ionian and Adriatic Mediterranean were most severely impacted by bottom trawling.

A brilliant example ⬇️ of how utterly exciting it can be to look at plankton through a microscope

There were a few of these bryozoan coronate larvae in my plankton sample this week. Keep watching for the larva in slow motion!

Just worked it out we have been coming to this restaurant for 18 years - we still think the best Helsinki has to offer is

Final format of my first article is now out! We discovered that degrading palsa permafrost might not lead into higher loading of organic matter into the river system. Also, we discovered that microbial communities were dominated by ultra-small Patescibacteria 🦠

Carbon and microbes in a degrading palsa mire are distinct from a peatland and a wider connected sub-Arctic fluvial system

Abstract. Climate change is altering the biogeochemical cycling of carbon and nutrients in the northern peatland and permafrost regions, which provide two

Using Pogies for the hands is a real game changer this year…..much of the pain gone 😀

Strava just told me that I had just done “an easy morning ride in Helsinki”
I beg to differ…..it was 13 km of serious #wintercycling with temp down to -21oC in places…..enjoyable, yes but not easy Strava 😀

Wintering Rothera jobs now listed for 2026/27/28 posts, for anyone who wants a year in Antarctica diving and/or boating and doing/supporting the year-round time series and benthic studies. Please share. www.bas.ac.uk/jobs/vacanci...

Small boat sampling, roles are Ocean Scientist (CTD time series, lab work, diving projects) amd Marine Biologist (large diving project). Plus Boating and Diving Officers and marine Operator to support them and other base needs for boating

Sampling continues through the winter, unique within the Antarctic Circle and rare anywhere in a polar environment

Ryder Bay, the time series point is in the middle, roughly where the chevron of rock between the glaciers points to

The marine team also monitor larger animals, including our Orca pod (as seen on Frozen Planet wave-washing seals)

Back to the #HelsinkiBikeCommute this morning
#wintercycling in these conditions always gives a small sense of achievement before the work starts 😀

Great to see the final formatted version now published.
@neatuomela.bsky.social led a concept-chllenging study about how thawing/degrading #permafrost palsas do not necessarily result in organic matter and the associated bacteria reaching the connected waters

Amazing to see the images of snow on Anglesey the last few days…….in the whole time we lived there it was such a rare occurrence

David N. Thomas @dnthomas01.bsky.social · 11d

The sea frozen into a massive mirror today

David N. Thomas @dnthomas01.bsky.social · 11d

down by the sea the temp sank to -20 to -23 for most of the my local loop.....inland it was a bit warmer

David N. Thomas @dnthomas01.bsky.social · 11d

#wintercycling at its very best today in #helsinki
No wind, good snow and down to -23oC (-9.4 F)
Tried using pogies for first time - worked a treat

Finally, Laajalahti in Helsinki has frozen over - a few brave souls testing its strength ( including one on a 🚲)…..we will leave it a few more days 😀

Sea level rise has doubled in last 30 years - now around 0.5 cm per year (or 0.2 inch per year) 😱

This replaces my earlier erroneous re-post that recklessly got the units wrong. This important message does not need folks (who should know better) making stupid mistakes about the units - my apologies
