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 4 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 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
Slesserev: Enhanced rock weathering lacks field proof even locally
“The catch is that we still don't have many field studies, and so it hasn't really been proven even at a local level, let alone at scale. And it's, I It's probably pretty hard to quantify how much CO₂ is actually being removed via that pathway. There are many p…”
Slesserev: No-till farming can actually deplete soil carbon at deeper depths
“Basically shifting tillage regime it means that not only are you changing the biology of the system and the rate at which carbon Flows through it, but also changing the vertical distribution of carbon, because tilling soil mixes carbon, and it also influences …”
Slesserev: Unclear If Soil Erosion Is Net Carbon Source or Sink
“For instance, that erosion question I just brought up earlier, there's been an ongoing debate about, you know, whether
The erosion of soil and transport of that carbon amounts to a source or a sink of CO₂ to the atmosphere.
We don't really even feel certain ab…”
Slesserev: Crop Agriculture Adds Less Deep Soil Carbon Than Perennials
“Converting ecosystems that were composed of deeply rooted plants, like perennial grasses, with ecosystems that are managed by humans and composed of
Our crop plants, which tend to be fairly short-lived and hence shallow-rooted, and therefore add less carbon to…”
