What predictions have come true? Name them, and give details.
I could predict that, it's going to rain sometime next month, and chances are that, I'll be right. I could also predict that, we're going to have a very warm next summer, and, I could turn out to be right. Likewise, I could predict a very cold and snowy winter in about 3 years, due to "global warming", and, if I turned out to be right, I could claim that I was right about a "global warming prediction".
"Global warming" had to be changed to "climate change" when the predictions that were made about consequences, didn't happen, and instead, we got some 13 years of cooling, which was the complete opposite of the predictions. Now, there are researches and scientists predicting that, we're entering a period of cooling that will last some 30 years or more. Fact is that, a "science" which is prone to so many errors, is no science at all.
Denial is more on the part of those who wish to convince people about a disaster, which fails to materialize. Long range climate change is difficult, even for the best scientists and for climatologists, and, astrologists probably have better records for predicting the future than the doom-and-gloom fraudsters.
