The undefinable science of Global Warming-Unprecedented
The first in a series of articles on the “science” of global warming beginning with a look at the not so unprecedented term “climate change”

Over the past couple of decades the climate cult has sought, with varying degrees of success, to convince the masses that man-made greenhouse gasses particularly carbon dioxide are primarily responsible for global warming a term which over the years has morphed into the far wider thus less definable “climate change.”
Our friendly government bureaucrats over at the Environmental Protection Agency which is a temple for the climate cult define climate change as:
“… any significant change in the measures of climate lasting for an extended period of time.”
Like the term climate change itself, the use of descriptions such as “extended period of time” is another one of those rather ambiguous terms that the cult uses so that they can set the parameters for their theory as it fits their needs. This is not the EPA’s fault the climate science community has never actually defined the length of time which constitutes a region’s climate nor is that even possible because, well, climate changes. This is why the EPA in their description of climate change goes on to say:
In other words, climate change includes major changes in temperature, precipitation, or wind patterns, among other effects, that occur over several decades or longer.
Again we are left with no specific time frame in which to judge “climate change.” We just know that when the climate of a region changes from one set of observed norms to another over a “period of time” it is climate change. A rather well know though seldom commented on example of “climate change” would be the Sahara Desert which not all that long ago was a lush paradise
“The climate change at [10,500 years ago] which turned most of the [3.8 million square mile] large Sahara into a savannah-type environment happened within a few hundred years only, certainly within less than 500 years,”
In a period of time “less than 500 years” the Sahara Dessert was transformed from a desert to place where:
Humans also frolicked in the rain pools, as depicted in rock art from Southwest Egypt.
In the more southern Sudanese Sahara, lush vegetation, hearty trees, and permanent freshwater lakes persisted over millennia. There were even large rivers, such as the Wadi Howar, once the largest tributary to the Nile from the Sahara.
“Wildlife included very demanding species such as elephants, rhinos, hippos, crocodiles, and more than 30 species of fish up to 2 meters (6 feet) big,”
Then sometime around 5,500 to 7,300 years ago the “climate changed” and the lush paradise was again transformed into the desert we see today. All without benefit of the exhaust from your Ford.
Over at Penn State the current place of worship for a high priest of the climate cult, Michael, the Hockey Stick, Mann, a group of researchers recently put out a press release on a just published study which begins,
