To avoid disaster, we should convert with all possible speed to a zero-carbon-emissions society.

I have to comment on some minor points.

• It is a shame to cite Bill Gates as a positive example of anything. If the point is valid, it can be established without mentioning him.
• I distrust carbon offset schemes because many of them make presumptions about future activities that may not come true.

But these do not invalidate the article's conclusion. They only affect side issues.
