Studies have shown that Americans' IQ is steadily declining, and brain capacity has dropped by another 10%, is it the fault of mobile phones?

Global warming has led to a 10% decline in human brain volume, which is about the size of 4 ping-pong balls, due to climate stress, of which global warming is the main cause. The brain volume increased by a factor of 4 and then decreased by 10%, due to environmental stress, social and cultural factors. Recent studies have shown that Americans' IQs are declining year on year, and similar findings have occurred in countries such as Finland, France, the United Kingdom, Norway, Denmark, Australia, the Netherlands, and Sweden.
