Yes, the radioactive waste that has been dumped in the ocean on purpose and disasters like Fukushima will affect crow rate of mutation for thousands of years, they're already intelligent as a human child and have the ability to coordinate attacks with facial recognition. It's radioactivity greatly speeding up rate of mutation that can make crows as smart as a human teenager. That's the thing, the damage has already been done even if we stop using nuclear energy and it's just a matter of time before Chernobyl's crows mutate to be smarter than some of the human adults. Oceanic radioactivity namely there are crows along seashores too. What we need is safer power plants and to send nuclear waste to the sun with rockets where radioactivity is native, the more radioactivity and disasters we have the greater rate of crow mutation. Solar energy and solar panels release toxic chemicals into landfills after ~15 years when they are discarded, toxic chemicals are another cause of accelerated rate of mutation and crows are common to landfills. If you don't avoid horror it will be a rude awakening from denial in a horror movie so realistic it's real. Never mind the 50+ foot long climate change pythons, they have indeterminate growth only limited by average year-round temperature. It's best to allow people to deny science and not try to convince them, more obvious to them that way.
