I draw up the following sentence from Studio Classrom. The Global Warming is mentioned in previous paragraph.
What is less clear is what is causing global warming--and what we can or should do about it.
翻譯：引起全球暖化的原因，及我們可以做或應做什麼還不明朗．
有字被省略掉了？？？
I make my own sentence:
The reason cause global warming and what we can or shoud do, which are still not clear yet.
請高手幫忙解釋和更正．

引起全球暖化的原因，及我們可以做或應做什麼還不明朗．
沒錯
"what is less clear" 有東西不明確，什麼不明確呢? 有以下兩點
1. "what is causing global warming" 全球暖化的原因
2. "what we can or should do about it" 我們能做或該做的事
把兩點當一點用
所以
What is less clear "IS" what is causing global warming--and what we can or should do
about it.
The reasons, which cause global warming and what we can or should do, are still not clear yet.
這句也通但是沒有前一句強勢←這是我個人感覺
p.s. can-能 (不是 could，因為還沒做)
should-該
