A new study in “Climate Dynamics” has criticized a key methodology that the Intergovernmental Panel on Climate Change (IPCC) uses to attribute climate change to greenhouse gases, raising questions about the validity of research that relied on it and prompting a response from one of the scientists who developed the technique.

The new study’s author, economist Ross McKitrick, told The Epoch Times in an exclusive interview that he thinks his results have weakened the IPCC’s case that greenhouse gases cause climate change.
