JD Vance had the #water level of a lake manipulated to accommodate his vacation plans.
It's not always the big corruption stories that rankle.

Mitenkäs olisi lisäksi vielä sellainen joka sopeuttaa planeettarajoihin ja varautuu 2050 luvun toimintaympäristöön? Tulevien sukupolvien ministeri olisi myös pop.

Purra esittää opetushallituksen lakkauttamista saadakseen huiman 15 miljoonan euron säästön.

Bensaveroale laski bensan hintaa ~0,05€ ja vei valtion kassasta 170 miljoonaa. Olutveroale laski tölkin hintaa ~0,03€ ja vei kassasta 25 miljoonaa.

The constitution. They sliced out the parts of the constitution that they don’t like from the government website.

The heatwave in Sodankylä has now lasted for 26 days.

This is probably not only the longest heatwave in Lapland, but also the longest heatwave ever observed in Finland.

Note that here a heatwave is defined with 3 consecutive days above 90th percentile, which is scientifically robust definition.

Wow, that is quite a clever deception to downplay sea-level rise in the DOE climate report.
You have to read the vertical axis label in their graph and understand what “trailing trend” means.

Numerot näyttävät luomutuotannon hiipuvan, mutta muutama tuote näyttäytyy valopilkkuna Luomutuotantotilojen ja -peltojen määrä laskee, eikä Arla tee uusia luomusopimuksia. Kaupan ja viljelijän mukaan markkinassa on silti toivoa ja uusia mahdollisuuksia.

Tämä on huono uutinen, sillä #luomu on yksi hyvä keino parantaa #luonnonmonimuotoisuus -arvoja ja #huoltoturva a. Nykyään on vaikea löytää esim. luomuleipää kaupasta. EU:n tavoite on nostaa luomutuotannon osuus 25% 2030 mennessä.

Inspired by @ketilisaksen.bsky.social post, I did the same analysis for Finland.

In terms of 14-day average temperatures, the 2025 heatwave in Finland did not quite surpass the well-known 1972 and 2018 heatwaves.

This is based on 10 km gridded observations.

The record-long streak of 30 °C in Finland finally ended yesterday. The outcome was an impressive 22 consecutive 30-degree days between 12 July and 2 August.

Who would have believed in June? Not me at least.

Thank you! Do you know, if anybody has translated these to estimated cost changes? (I'm looking at what could the prices of commodity crops be in 2050.) There seems to be demand going up and supply going down. Might be a big change for ag.

AMERICAN ECONOMIC ASSOCIATION
Committee on Economic Statistics and Committee on Government Relations


Statement from the American Economic Association on the
Dismissal of the BLS Commissioner

Leaders of the American Economic Association express their grave concern over the dismissal of the Commissioner of the Bureau of Labor Statistics (BLS) earlier today.
The independence of the federal statistical agencies is essential to the proper functioning of a modern economy. Accurate, timely, and impartial statistics are the foundation upon which households, businesses, and policymakers make critical decisions. Undermining the independence or credibility of these agencies threatens the integrity of the information that markets, institutions, and the public rely on every day.
Measuring the vast and dynamic U.S. economy in real time is inherently challenging. It is standard practice for statistical estimates to be revised as more complete and higher-quality data become available. These revisions reflect the commitment of statistical agencies to accuracy, transparency, and methodological rigor-not failure or bias.
The BLS has long had a well-deserved reputation for professional excellence and nonpartisan integrity.
Safeguarding this tradition is vital for the continued health of the U.S. economy and public trust in our institutions.
We call upon elected officials to respect and preserve the independence of the nation's statistical infrastructure.
