The Dysonian View of Global Warming/Climate Change.

[Lafiel]

when was this recorded ?

first off, he does ofcourse say some things that are correct, the whole carbon cycle with soil/rock,oceans, biomass and atmosphere is far, far, far too complex to accurately model in it's entirety and the real world will probably show effects that differ from the computer models

but some things just make me shake my head in disbelief
he thinks irrigation can bind much more carbondioxide than we can release by burning coal and oil .. that's ridiculous, because coal and oil _are_ plants/maritime algae and not just 1 generation, it's millions of generations (without many of the volatile components like most of it's hydrogene, oxygene, nitrogene etc) per ton

a natural grassland gathers more carbondioxide than any field - not in 1 generation, but it actually can aggregate more and more over time, while an agricultural field is a short term carbon cycle at the very surface of the soil, it's maximum CO2 binding capacity is reached just when the plants are harvested, because ploughing negates any material sinking deep into the soil and being servered from the atmosphere that way

so, the only places in which agriculture can bind additional carbondioxide is in todays desert, yet you need water, which needs to be pumped (> needs electricity, likely from fossil power) either from (often) far away lakes or oceans or from fossil water reserves deep in the ground (much less effort), yet those mostly aren't replenished, so after a few decades they are empty
making those deserts into non-agricultural grasslands means taking the same efforts without making any revenue/profits from that -> won't happen

by the way his focus on vegetation is obselete, soil is the biggest reserve for carbon dioxide and the warmer it gets in places like sibiria and greenland the more carbon dioxide will be emitted from it's permafrost soil which was a gigantic carbondioxide reserve, but now can interact with the atmosphere again, because the warming effect is far bigger closer to the poles (which triggers him to state in the article "I don't think it's global" ? ridiculous)

the second biggest reserve is the ocean and maritime life, the ocean's acidity level has increased dramatically due to carbondioxide being absorbed as carbonic acid and maritime life suffers because of that, especially those unicellular organisms that generate shells/skeletons from chalk (one of the components is carbon) and actively decrease the amount of carbon in the short term carbon cycles that way
