> Using cost-equivalent deployment scenarios across 22 U.S. grid regions from 2020 through 2050, we compare direct air capture to utility-scale wind and solar under multiple grid and technology scenarios. We find that renewable energy deployment yields greater combined climate and public health benefits than direct air capture across nearly all scenarios and regions, with direct air capture approaching cost-effectiveness only under highly optimistic assumptions about future technological breakthroughs.

> The push has fueled speculation — especially online — that the Vatican could build a kind of "truth engine," a system to authenticate information or arbitrate reality.

There are no sources, I've never heard this, it doesn't make any sense, and after a quick search I can't find any other reference to this idea. Did the author just completely make it up?

I don't think any of this is true and it doesn't even follow from the rest of the article.

For investigative journalism, if it even qualifies as that, this is pretty shallow. It's good work but it's just some public data and a couple hours of work, not a deep invasive investigation. It also is not freelance, this is a staff reporter for a decades-old publication.

Even as an insider it's hard to understand how a country could re-elect the worst person on earth and then two years later vote the opposition into power, so it's hard to believe that outsiders are taking such a nuanced view.
