There is an easy way to keep up with this kind of information. It's called "paying attention to the news." It can be supplemented by a high-tech method I call "doing a Google search."
Don't let the deniers snow you. They are counting on your not being willing to spend a few seconds searching Google or Bing. Don't let them have the satisfaction. Call them on their BS whenever they trot it out. If enough of us do it, maybe it will shut them up, or at least force them to come up with new lies.
