The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 5 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 2 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable

“We make about two billion tons of steel today, every year. We think by twenty-fifty that's going to peak and level out at about three billion tons.”
Atwood: Electric arc furnaces can easily run on intermittent renewables
“Electric arc furnaces can use intermittent power, so they're great if you just plug them into wind and solar, because you're making the steel in batches.”
