Views on climate change

Christy is of the opinion that the climate models would indicate the global temperature rise too high compared to the measured data. He does not deny the rise in temperature as such, but he does not see it as a threat to humanity.

In an article for the Center Daily Times in 2014, he stated that the complexity of the climate was poorly understood. Since the various theories cannot be tested in the laboratory, computer simulations are a way of investigating them. The temperature rise calculated with them, however, is z. In part three times higher than the actually measured temperature rise. Christy also said in 2008 that his research failed to substantiate predictions made by other scientists of "catastrophic" climate change.
