Nova vs Nova vs Nova

The IPCC reports present science that shows the climate is warming and that amongst the numerous forces that affect climate, man-made greenhouse gas (GHG) emissions have been a major contributor in recent times.

By contrast, Joanne Nova offers confusion. In her “merchant of doubt” role, she has no qualm about presenting contradicting theories. Her posts blame anything but CO2 for the warming.

On topics of warming, feedbacks & attribution, Nova flips back and forth. Sometimes Nova agrees that it is warming, other times she casts doubt on the thermometer record, occasionally declaring the warming has stopped. Most times Nova disputes the water vapor feedback mechanism, sometimes she unwittingly supports science that says it accounts for half of the observed warming.

On occasions when Nova does conceded that it’s warming, she flip the blame back and forth between the popular, already debunked myths of solar, natural cycles, oceans and cosmic rays. It’s difficult to have any confidence in Nova when she changes her mind on such a regular basis.

Nova’s “science” posts discussing whether or not it’s warming and the cause, are summarised below.
