@johncarlosbaez@mathstodon.xyz Have you looked at the comments on Facebook? It is where all the anger and the hate against everything decent dominates. Hate against the government, the courts, the left, the gays, the women, the immigrants, the minorities, the cyclists, etc, etc. It is how Zuckerberg makes money: by stimulating rage and rage bait. In the US, there was pizzagate. Another example is India, where inflammatory posts on Facebook incited sectarian violence. @nmvdw@mathstodon.xyz

@AccordingtoWouter@mastodon.world Vroeger was er vast wel een kruidenier veel dichterbij. Die is verdwenen omdat "iedereen" bij jou in de buurt zijn inkopen met de auto is gaan doen bij een grootgrutter. Maar ook hier in Appingedam lijkt bijna iedereen met de auto naar de supermarkt te gaan. Er staan nooit veel fietsen. En dat terwijl het overgrote deel van de klanten vast en zeker op minder dan twee kilometer afstand woont. @ligfries@mastodon.green @technetium@mastodon.nl @lalage@mastodon.nl @Wouter_Pieterse@todon.eu

@musevg@23.social Embarassed Dutch guy here. The new government is lead by Jetten, who is the leader of D'66, which used to be a slightly left of center liberal party. I had high regard for previous leaders like Van Mierlo and Jan Terlouw. Jetten on the other hand does not seem to have any convictions whatsoever and is now catering to the voters on the right: the well-to-do and the deplorables. @josemontesinos@masto.es @swaldorff@swiss.social @randahl@mastodon.social

@christinkallama@hcommons.social There are always variations, also between different provincies in countries with the same policy. Despite keeping Sweden open and not masking, we did not have a high mortality compared to other industrialized countries. It was about the average for the EU. And locking people up did not really help anywhere. @luckytran@mastodon.social

@foxylad@mastodon.nz Indeed, in low orbit it cannot work at midnight (except in areas in the far North or South), no matter how many thousands would get launched. This one's orbit is just a bit above that of the ISS, which is only bright shortly after sunset or before sunrise, for a few minutes. The claim of providing light for rescue missions is totally absurd. I agree, this must be an investment scam. @sundogplanets@mastodon.social

@janiuk@mastodon.nu The researcher sounding the alarm over how the decline of Arctic sea could affect weather is Jennifer Francis. I have seen a few Youtube videos with her, both lectures and interviews. Here is a presentation for the Arctic Council: https://arctic-council.org/news/shifting-winds-how-a-wavier-polar-jet-stream-causes-extreme-weather-events/ She is a meteorologist/climate scientist so she does not publish about agriculture. But I saw some scientific publications about historic connections between the jet stream and harvests: https://www.nature.com/articles/s41586-024-07985-x https://www.nature.com/articles/s41561-025-01654-y.pdf I am no expert on this at all. It is not certain if or when this kind of disasters will happen (jet stream, AMOC collapse, or even the collapse of the 3-cell system of atmospheric circulation). But the effects would be much worse than shifting the wheat boundary by a few hundred kilometers (which is bad enough at present rates). I feel that it is quite likely that our weather will change quite a bit when Arctic sea ice disappears. That is why I keep an eye on Zack's graphs. @ZLabe@fediscience.org

@landetannien@mastodonsweden.se Pappa hade cykelaffär, min farfar var smed, morfar sysslade med elektriskt, radio, jordstrålar, osv (och bodde ett tag i Brasilien). Farfars farfars far var tunnbindare, så då man under den franska ockupationen skulle ta ett efternamn valde han Kuiper ('cooper' på engelska) Vidare har de flesta varit jordbrukare i Groningen, så det hade jag nog också varit. Ett liv i leran, på 1800-talet. Och jag hade förmodligen inte hunnit fylla 66.

Here a map of areas where the WBT did not sink under 25 C on June 27. That used to be rare in the old climate. It will get worse. A few degrees higher and nobody can survive such a day, not even fit young people. https://csi.climatecentral.org/humid-heat?card=city%3A65128&day=2026-06-27&ind=min&map=dangerous-humid-heat&uT=C&xyz=87.188_24.687_4&utm_campaign=csi-map-share

Remember: the unit of absorbed dose is the Gray which is 1 joule per kilogram. And 1 gray is an awful lot in terms of ionizing radiation but it is little energy and it gives rise to a practically imperceptible temperature change.

@BenjaminKlein@mastodon.nu Most of the members of this committee had their expertise in political science etc, not epidemiology. Their conclusions support that the Swedish voluntary approach was correct. And what initial rigorous and intrusive control measures would they have taken? Stop people from returning from their wintersport vacations in March 2020? Putting them in quarantine camps? Was there any basis for that at the time, any evidence that it would have worked? Even now there is no evidence that such measures would have helped to keep the totals down. Initially, there was the official recommendation not to travel further than about 100 km. That measure was intended to delay the spread through the country. It was probably useful for some time in the beginning. @christinkallama@hcommons.social @luckytran@mastodon.social

Higher than "world" but that just means that Sweden was testing better than the global average. So what do you suggest Sweden and other countries should do?

@sanderturnhout@mastodon.green Nou, de gemeenten doen ook mee aan die framing. Allerlei evenementen kregen geen vergunning vanwege "stikstof". Zelfs wandeltochten, naar het schijnt. Terwijl gemeenten zeggen ertoe gedwongen te zijn om vergunningen te verlenen voor intensieve veehouderij. Het zal wel te maken hebben met de kans dat er beroep wordt aangetekend.

@janiuk@mastodon.nu There is a scenario that serious food shortages could happen quite soon when more Arctic sea ice disappears. According to Jennifer Francis, that might lead to summers where the jet stream would not push the high- and low-pressure areas around much anymore. This would then cause consecutive years of simultaneous failed harvests all over the Northern hemisphere. Some years because of drought, some years because of cold and rain. So this could happen long before the average temperature goes up too much for wheat etc. To deal with such problems humanity would need to share the available food equitably. I fear that that is getting less likely. @ZLabe@fediscience.org
