Great Lakes – a case study of failed predictions

In 2012, National Geograhic published an article outlining the impact of climate change on the Great Lakes in North America. The article provides details of how the lakes were at almost-record lows, and that the temperatures were warming. The winter ice-cover had declined by 73% in the 30-year period since 1973. The article noted:

With nearly 20% of the world’s surface freshwater at play and millions invested in restoration efforts, the stakes are incredibly high for understanding how natural climate variability and human-induced climate change affect the Great Lakes.

Now, seven years later, lake levels are at record highs, as outlined in a study presented by Dr Roy Spencer.

In addition, ice-levels in the lake have reverted to previous winter levels, as shown in the following graph, sourced from the US NOAA-GLERL (Great Lakes Environmental Research Laboratory).

In summary, the weather situation in 2012, reported by the National Geographic, was not climate change, it was weather, and the predictions of catastrophe have been shown to be invalid.
