    Well, he was amping it up and catering to John Oliver.

    Agriculture done in ways that increase carbon storage in soils:

    Carbon Farming Could Sequester Billions of Tonnes of CO2, with U.S. Pilot Project as One First Step - The Energy Mix

    including a link to their Special Report.

    I will comment on one aspect of this. Says there that 30% of sugars (proximal photosynthate) goes underground. Perhaps true, but it is an area with very little research. And not easy to do. it could be much better constrained by knowing what fraction of net primary production becomes leaf litterfall. This is the largest biotic carbon flux still awaiting a pull-together review, Yours truly has been trying to hornswaggle somebody into doing it for a long time. There are about 2000 site-specific studies (some in 'obscure' languages*) and perhaps 18 person-months of pulling-together to be done.

    Okay, that is awesome.

    Paper is a collection of torn up cellulose fibers that is randomly put back together. This process leaves the fibers and arrangement of cellulose mostly as is before the treatment. Add glue, resins with pressure and/or heat to the paper, and you can it back and beyond its strength when it was wood, but the added material will inhibit its cooling properties, assuming those weren't ruined when the cellulose was all chopped up.

    With 381 climbing permits this season and 11 deaths so far (mostly in the past week, while waiting for hours in the 'traffic jam' near the former Hillary Step in the oxygen-deprived 'death zone'), that regular trash is almost certainly piling up again. The frozen body accumulation certainly is.

    I did find a climber's version of comparative oxygen availability, adjusting for latitude and local climate and season. In cold seasons and polar zones, the higher density air at lower elevation leaves less pressure available at the mountain peaks. But Everest still wins this oxygen starvation contest:

    Nice chart. do not know if Everest has shrugged off a record # of visitors this year, but it's a lot.

    Very well-known to those living in urban areas with (real) winter - Months' of deposits by household pets getting exercise thaw out and become fragrant at the same time.

    There is a rural analogue. Whatever lands on snowpack tends to stay there until last bit melts. Yrs trly usta drive around Adirondacks to collect stream water samples. Those have a sharp nitrate concentration peak right when one would expect.

    I think the climb costs +/- $11,000 for a permit and another +/- $30,000 for a sherpa. Bag and carry your trash and personal waste. Miserable prick rat-bastard rich people don't think they owe anyone anything just leaving all their garbage everywhere anywhere they want. I really hate that kind of irresponsibility.

    Paper @968. This seems a reasonable objection. Wood 'fibers' are about 10 cm length scale while paper are shorter (recycled paper short still). But even in conventional paper there is a fiber-laying bias that is obvious when one compares neatness of tearing in different directions. I am thinking that fibers in paper could be further manipulated to make a structural product. Which may or may not have "cooling wood's" radiant properties.

    Heavy chemistry is involved in that product. If it cannot be avoided, well that's that.
