My criticism is a massive L1 sunshade does absolutely nothing to solve the underlying problem, merely mitigates one of its effects while suppressing photosynthesis, reducing that aspect of the planet's ability to attack the underlying problem. There is only one solution to the problem which is to stop dumping carbon into the atmosphere and accept the consequences for our lifestyles. The Earth will take care of the rest.
