How to decide if there is anthropogenic climate change

The problem with climate change is that the science involves several branches of physics including thermodynamics and electromagnetism, chemistry, biology, as well as interdisciplinary fields such as meteorology, geography, and oceanography. In some ways these various disciplines compete for centre stage in climate change theory and very few scientists are expert in every field of climate change science, which means that to a large extent they must take on trust what other scientists find. Scientists tend to have a bias towards their own field of expertise, so possibly over estimating the importance of their own branch with which they are so familiar. Continue reading
