It will be noted that

因为不确定,我还是仔细翻了翻字典.
note 的英英解释是observe,notice,也就是注意,所以it will be noted that应该是“值得注意的是”（从意思上理解,will是将要,作者希望读者将要注意到,也即值得注意）,翻译成“值得指出的是“也是正确的.
it would seem that应该是带有一定假设语气的说法,就翻译上来说跟it seems that基本一样,但是好的翻译应该带一些委婉一点的语气.
比如：
Are human beings still evolving?
It would seem that evolution is impossible now that the ability to reproduce is essentially universally available.
人类还在进化吗?
既然人类已经普遍具备了完备的生-殖能力,进化这种说法在目前看来似乎是不太可能的.
上述就比较委婉.
