Michael Mann says bitter cold is consistent with global warming

It probably is and the reasoning he gives in the article excerpted below is plausible.  The professional Warmists at NOAA, however, predicted a WARM winter:  Another failure of their theory and its appurtenant models.

Mann is however not abashed by yet another failed prediction. He "explains" it.  His explanation is however what in science is known as an "ad hoc" explanation and just about any data can be explained "ad hoc".  In plain language it is known as "being wise after the event".

In science, however, the need for an a hoc explanation is seen as damaging to the theory and requiring revision of the theory. And it normally takes only a few failures of theory predictions  for the theory to be discarded altogether.  With global warming, however, NOTHING is ever taken as damaging to the theory. And in the philosophy of science an unfalsifiable theory is regarded as not being an empirical statement.  It can only be a statement of faith.


The US East Coast is experiencing an “old-fashioned” winter, with plenty of cold weather and some heavy snowfall in certain places. Listening to climate contrarians like President Donald Trump, you might think this constitutes the death knell for concern over human-caused climate change.

Yet, what we were witnessing play out is in fact very much consistent with our expectations of the response of weather dynamics to human-caused climate change.

Dr. Michael Mann on Extreme Weather: “We Predicted This Long Ago”

Let’s start with the record five-plus feet of snowfall accumulation in Erie, Pennsylvania, in late December. Does this disprove global warming? “Exactly the opposite,” explains my colleague, Dr. Katharine Hayhoe of Texas Tech University.

Global warming is leading to later freeze-up of the Great Lakes and warmer lake temperatures. It is the collision of cold Arctic air with relatively warm unfrozen lake water in early winter that causes lake effect snows in the first place. The warmer those lake temperatures, the more moisture in the air, and the greater potential for lake effect snows. Not surprisingly, we see a long-term increase in lake effect snowfalls as temperatures have warmed during the last century
