Causal Linkage between Carbon Dioxide and Global Warming (Part 3): Causal Criteria Still Wanting
The Australian government is planning to introduce an emission’s trading scheme, also described as a carbon pollution reduction scheme, on the basis that that carbon dioxide from the burning of fossil fuels is contributing to dangerous global … [Read more...] about Causal Linkage between Carbon Dioxide and Global Warming (Part 3): Causal Criteria Still Wanting
Causal Linkage between Carbon Dioxide and Global Warming (Part 2): Still Searching for Evidence
On Sunday a colleague and I discussed the general issue of correlation versus causation in science. He suggested that 1. There must be a body of work establishing a causal link between anthropogenic carbon dioxide and warming, and also 2. Some work … [Read more...] about Causal Linkage between Carbon Dioxide and Global Warming (Part 2): Still Searching for Evidence
