23 years ago, climate scientists were predicting that, "snowfall will become "a very rare and exciting event" and that "Children just aren't going to know what snow is" [1], in Britain.

In 2008, James Hansen, an influential climate scientist at Columbia predicted the Arctic would be ice free in the summer by 2018 [3]. Instead, the sea ice trend reversed in 2012 and since rebounded to higher levels than when Hansen made the prediction [4].

Furthermore, the predictions of dire consequences as a result of CO2 increase or mild warming have not materialized. Instead global biomass has dramatically increased and crop yields continue to achieve record highs, which is what you would predict as a result of increased plant growth from CO2 fertilization [2].
