Shackley

基本解释

"No one has yet succeeded in recreating terra preta," Shackley adds.
沙尅利還補充道：“至今還沒有人能夠成功地複制出印第安黑土。”
But those estimates relied on heroic assumptions about the ability to make biochar easily around the world, says Shackley.
但是，沙尅利卻認爲這些估算是建立在不切實際的假設基礎之上的，他們假設生物炭可以非常容易地在全球範圍內生産。
This may seem disappointing in comparison with previous grandiose claims, but it still represents an impressive potential contribution from a single method, Shackley says.
沙尅利認爲，盡琯與之前的天文數字相比，現在的數字似乎有些讓人失望，但是作爲單一手段，它的潛力還是很大的。
