The only way to consume news, without subjecting oneself to the inner turmoil that the news is designed to produce, is to develop a long term theory and then just check in with the headlines to make sure that things are progressing toward it.
If they don't seem to be, adjust the theory and then keep-on with the aforementioned method.
Sure, some people emotionally need to be apprised of the tragedy of every story. They may even convince themselves that the World's trajectory hangs on the balance of every event. I'd suggest that this is both irrational and hints at addiction behavior. But if this isn't you, or you want to become less addicted, then give the above method a try.
After awhile, you'll begin to admire the efficiency of and relative inner-peace from your new hard-won detachment skill.
