Excellent and thought provoking article.
I have been looking into climate change for the past several years and only wish this article had been read and understood several decades ago. Then we might have a very different view of the causes and not be driven to only one cause ( human activity and carbon/CO2/GHGs ). Unfortunately, these are the only ones being considered ( based on previously collected data, without consideration of other possibilities for which data was not collected or readily available ), and this is cconsuming much time and effort and will likely have little effect on climate change. Recently, we have seen that the Earth itself is contributing in a very large way to climate change, but this has been largely ignored because of the previously collected data which did not include looking at alternative possibilities. Apparently people were not thinking broadly, asking questions and using diversity.
