It’s just delirious. None of this makes any sense.
Trump says he'll impose a 10% tariff (rising to 25% in June) on Denmark, Norway, Sweden, France, Germany, the UK, the Netherlands and Finland, because they've sent people to Greenland, until the US can buy Greenland.

Yeah, I was right in the middle of it. And yeah, the whole “dark fiber” thing was a wonder to behold. Now we have “dark GPUs” that will be obsolete by the time the data centers are built, which are waiting for the power and water infra. Yeah lots of companies are going to die.

Things are not looking great. How on earth is this possible?
Evidently there was an Auschwitz-themed float in a Halloween parade in Pennsylvania.
The float was for a Catholic school, and to their credit the church immediately disavowed it.
Thing is, I don’t think high school kids did this entirely on their own. I’m guessing parents had to be involved.

Let's just say the Wikipedia entry has neither an "Economic and Policy Critiques" section, nor one on the "Role of Media and Advocacy" that accuses both of bias.

![Role of Media and Advocacy
Media coverage of climate change has often emphasized catastrophic scenarios and extreme weather attribution, contributing to heightened public alarm. A 2022 study analyzing English-language news media found a significant reporting bias favoring storms and wildfires, with these events receiving disproportionate attention compared to droughts or other impacts, potentially skewing perceptions of risk materiality.[219] This selective focus aligns with broader trends where outlets attribute unusual weather—such as heat waves, floods, and hurricanes—to anthropogenic climate change, even when causal links remain uncertain or unproven.[220] Such framing has fostered a moral panic, as mainstream reporting routinely overlooks empirical inconsistencies in alarmist predictions, including historical forecast failures like exaggerated sea-level rise or Arctic ice loss timelines.[221]
Advocacy organizations, including non-governmental groups like Greenpeace, Sierra Club, and Extinction Rebellion, have played a pivotal role in amplifying these narratives through campaigns, protests, and public shaming tactics. These entities mobilize grassroots pressure and influence policy by correlating their activities with shifts in public opinion on global warming, with studies showing moderate positive associations between environmental NGO presence and supportive attitudes.[222] For instance, Extinction Rebellion's 2019 actions, including street blockades in major cities, aimed to disrupt normalcy and demand immediate emissions cuts, drawing global media attention and pressuring governments toward net-zero commitments.[223] International NGOs further exert leverage via reputational costs, using public opinion channels and transnational advocacy to shape national laws, as evidenced in analyses of "climate shaming" campaigns.[224]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:3nekuksdc3y37mr7q66aaq4d/bafkreiakb3ivnv4lzjhhfgr6t3ospchzdc5knzhfyxu4abtqgconftvuou@jpeg)

The @python.org foundation is fundamental in maintaining python. Y'all are waiting for the huge benefits of AI to materialize? Good luck without a working python ecosystem. Trump has cut funding, because they are here for everyone ("diverse and international"). You can chip in, 25$/year. #econsky

Look, I dont care about about your accent or limited vocabulary in English. But the Spanish Erasmus student standing in front of me, punching Spanish sentences into her phone, so that she can “talk” to me is one step too far. You must speak basic English. It’s embarrassing.

The amount is meaningless — less than one day of salary. But the principle is important: once the armed services are paid by the oligarchs, they become a private militia, and we no longer have a country.

Trump doesn’t like climate change, so he just stops funding climate research. Great explainer by FT what this means. Obviously not smart to fly without any data through the haze in general, but even short term outcomes (weather forecasts, insurance premia etc) are under threat. on.ft.com/4nZI1II
