Nova “Science”

Joanne Nova’s approach to climate science is to cast doubt on what we do know, rather than present facts that would counter the scientific concensus. It’s a tactic used by tobacco companies, and now climate denialists are doing the same.

On Nova’s website are posts of political nature, now and again she will present science in an attempt to mislead her readers into thinking that warming is not happening, or that it’s happening but it’s not greenhouse gases, or that it’s happening but nothing to be concerned about. Below are a number of contradictions, cherry picking examples and finally a list of Nova’s topics that I am slowly working my way through and providing the rebuttal.

Contradictions

Nova’s attempts to cast doubt on the science of global warming and in doing so presents many contradicting theories. Some say it’s not warming, some say it’s warming and it’s the sun, some say it’s warming and it the oceans, some say it’s just all a hoax.

Cherry Picking

Nova misleads her reader by only selecting small bit of science or data that supports her political position. This results in a contrived position that becomes all too obvious

Nova’s “Science” Posts

Amongst her myriad of politically motivated posts, Joanne Nova occasionally will slip one in about the science. Unfortunately, as we’ll see, Nova’s science is founded more on web-blogger do-it-yourself, rather than on the peer-reviewed process which has been fundamental to bringing science to where it is today. I’ll continue to debunk Joanne Nova and her brand of science. Check back here over time – I’ll continue to grow this list.
