I always find it funny that deniers say that the Earth has always had warming and cooling trends over the eons. How do they know this? They listened to climate scientists who have done the research into the Earth’s past and shown that this is true. Yet when these same climate scientists say that what we’ve been experiencing these last few decades IS NOT normal, they refuse to believe them.Suddenly the scientists are lying. So deniers, how do you know that the scientists were telling the truth when they said that the Earth goes through warm and cold periods???? Why do you only believe them when they say something that you want to hear, and don’t believe them when they say things that you don’t want to hear????
