An accepted truth like "climate change is real" isn't really that new today. Page 10: "Another professor agrees with the professor from last week who talked about this topic, read more on page 56." A protest turned riot about climate change is news. Crackpot theories are also new and news worthy.
The entire premise that the news is impartial and should cover issues statistically equally is utterly at odds with the core principle of what the news actually is.
The news is not information and never has been. It's telling stories about the world.
