Se on tietenkin vaarana, enkä sitä mitenkään vähättele. Vaikea vain tietää harmitellaanko 50v päästä katastrofaalisen ilmastonmuutoksen keskellä "Miksei käytetty kaikkia mahdollisia keinoja?" vai "Miksi nostettiin esiin ilmastomuokkaus?".

Tavallaan, mutta tuota argumenttia on käytetty jo parikymmentä vuotta, eikä ongelmaa edelleenkään olla ratkaistu päästöjen vähentämisellä, joten ehkä muitaKIN keinoja pitää tosissaan alkaa miettiä. Ja tuskin moni tällaisen kirjoituksen pohjalta muuttaa mieltään päästövähennysten tarpeellisuudesta.
New publication!🌥️
Maija Peltola et al. have measured new particle formation and aerosol properties at the CoastClim coastal atmospheric observatory.
The fascinating results showed e.g. new particle formation at the coast occurred roughly as often as in a boreal forest.

Before you start getting distracted by the holiday season, plan for 2026 by noting that we are again convening this session on atmospheric organics at #EGU26.
Over the last years I have shifted efforts towards the coastal environment, working together with ecologists and biogeochemists. Has been really exciting to learn new things, and now we even have a first publication out describing the atmospheric observations we have set up at our coastal station.
"academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it... The dominant four collectively generated... $12 billion in profits between 2019 and 2024."
This work started already pre-covid, which makes me even happier to see it finally in print. Thanks to @ayanezserrano.bsky.social for tremendous leadership in pushing it all the way through!
Happy to announce that our paper on "Unaccounted impacts of diterpene emissions on atmospheric aerosol loadings" has been published after years of efforts. Thank you!@mikaelehn.bsky.social @jpreixach.bsky.social @olgagarmash.bsky.social @apraplan.bsky.social @heidihellen.bsky.social

A rare bloom of Cosmo, CSU’s corpse plant, gave my group (Rose Rossell and @chemj.bsky.social) the chance to study corpse flower emissions in a fun collaboration with Tofwerk. Turns out to be an interesting, if stinky, story of pollination chemistry…
Det är dags för Finland och Sverige att ta FNs havskonferens på allvar! @tvarminne.bsky.social @ostersjocentrum.bsky.social @coastclim.bsky.social @balticseacentre.bsky.social @helsinki.fi

Sad I didn't manage to go to there myself this time, but thanks to Mace Head team for hosting these campaigns!
There is some "amazing stuff" in here on Climeworks and carbon capture / carbon offsets model more generally.
brief🧵 after the caveat that I have no idea if what is reported is true (but it mostly doesn't matter whether/if the numbers are off by >10x)
EGU coming up next week! See below for details on our session on atmospheric organics. Hope to see many of you there!

Oma kokemus: ChatGPT sanoi osaavansa kääntää MatLab-scriptin Igor-koodiksi. Generoi testipätkästä ihan kivannäköisen koodin. Tarkemmin tarkasteltuna siellä oli kuitenkin paljon virheitä. Jopa for-loopin syntaxi pielessä. R ja Python varmaan AI:lle helpompia, mutta kannattaa aina tarkistaa tulos.

Hello Bluesky! EGU is pleased to be able to activate our account here, and share all the exciting news about the upcoming General Assembly: #EGU25, our #OpenAccess publications and more! Several of our Divisions will be making the move over from Twitter/X too, so keep an eye out for your favourites!
Just over a week until EGU abstract deadline (Jan 15)! Come join us to learn about atmospheric organics! Featuring invited speakers @riikkarinnan.bsky.social and Matthew Coggon.
Maybe they want to convey that there's still plenty of room for things to get much worse...?
EGU 2025 coming up next spring, check out our session on atmospheric organics!
My postdoc Jian Zhao did a great job in figuring out how to improve the performance of the vaporization inlet for aerosols (VIA). One of these days we need to do a direct comparison with the EESI-TOF to compare spectra and sensitivities for online detection of SOA.
Can we, in real-time, deduce the ozone formation regime by measuring highly oxygenated organics (HOM)? In theory, yes. In a simple lab system, yes. In ambient air, we are still looking into it. In any case, since HOM were discovered, we have thought about these links, so was nice to now test it.
Finally I can identify with your posts! 🙁
I cannot identify with a single thing you said in this post! 🙂
I hadn't checked X for quite a while. Following your post I now did, and finally made the choice to completely deactivate my account there.
Now that AGU has wrapped up, time to start thinking about EGU in April! Abstracts are due Jan 10. Consider submitting to our session on organics:

If you are interested in atmospheric organics and conferences in Vienna, please consider submitting an abstract to our session at EGU24!
