I read the online Portland Press Herald, MSNBC and Google News which includes stories covered by all major networks. Basic stuff and I find stories on major iceberg calvings, climate change, etc. daily. There is no censorship. If the majority of people prefer to read about Beyonce and the latest kidnapping, don't blame the press.

Frozen Planet was not censored for the US market.

Climate change is a fact of life. When will you all wake up and realize that man is nothing but a blip on the grander scale? We will come and go as did the dinosaurs. Blame the Republicans if you must but look at history and pre-history. The earth is constantly changing. Species who adapt, survive. Those who can't disappear. Whether mainstream news covers it or not.
