Shackley

基本解释

"No one has yet succeeded in recreating terra preta," Shackley adds.
沙克利还补充道：“至今还没有人能够成功地复制出印第安黑土。”
But those estimates relied on heroic assumptions about the ability to make biochar easily around the world, says Shackley.
但是，沙克利却认为这些估算是建立在不切实际的假设基础之上的，他们假设生物炭可以非常容易地在全球范围内生产。
This may seem disappointing in comparison with previous grandiose claims, but it still represents an impressive potential contribution from a single method, Shackley says.
沙克利认为，尽管与之前的天文数字相比，现在的数字似乎有些让人失望，但是作为单一手段，它的潜力还是很大的。
