In the context of climate change, it is the opinion that more industrialization and technologization cannot help solving the problem, except in a few narrow acceptable directions (solar, wind, hydrogen etc).
An example would be the european reaction to AC. It's a way of using technology to solve warming, its costs are perfectly acceptable, but it is still frown upon because... well, it's beyond the scope of a HN comment to diagnose why, but it's an example of technology being able to mitigate a problem but not being allowed to.
