One of my favorite insane bad-weather-prevention proposals of all time: At the height of the CO2 hysteria in 2007, a peer-reviewed paper suggested that we spend $250 billion annually to hire and equip 200,000 crews of 10 people to cut down trees and bury them

Carbon Balance and Management | Full text | Carbon sequestration via wood burial
[2007]  If each trench has a 500 tC capacity (example in Fig. 6), then the number of trenches needed for a 5 GtC y-1 sequestration rate would be 10 million per year, i.e., one trench every 3 seconds. Assuming it takes a crew of 10 people (with machinery) one week to dig a trench, collect/cut and bury wood over a 100 hectare area, 200,000 crews (2 million workers) and sets of machinery would be needed. This estimate is admittedly simplistic and the task could be quite labor-intensive if it is to be carried out in dense or steep-sloped natural forests...The plausibility of this operation may be more easily comprehended from an economical point of view. A $50/tC cost for wood burial corresponds to $250 billion per year at a 5 GtC y-1 sequestration rate. This is only 0.5% of world total Gross Domestic Product (GDP) of $48 trillion in 2006, compared to the projected 5–20% GDP potential economic damage from climate change [8]. The $250 billion per year cost for 2 million workers means $62,500 per worker, assuming half is for machinery and other costs.

I've been reading your site every day, how did I miss this?...

Nice find. Confirms my belief that AGW is nothing but a means to redistribute wealth from rich nations to poor nations (and within nations) as well as to fund development projects (under the BS guise of climate abatement or whatever).
