There never was a climate consensus...

Let's keep our cool in the battle over global warming — Irish Examiner:

...The talk about a "climate change consensus" never was a scientific consensus about climate change but at most was a political agreement to act and speak as if the major questions surrounding climate change had already been answered.

In reality, however, there are very few things on which the majority of climate scientists would readily agree apart from the fact that the world is warmer than it was 150 years ago — about 0.7 degrees Celsius warmer; that we humans have released a lot of additional carbon dioxide into the atmosphere as the world population has grown; and that we are (to some debatable extent) responsible for global warming through increased energy and land use.

Everything else in the climate change debate is highly controversial. Has the climate of the past millennium always been colder than today or not? How much of an effect on the climate does atmospheric carbon dioxide have? Do rising carbon dioxide concentrations lead us to a point of no return? Or are there self-regulating mechanisms which will slow, halt, or even reverse the process? For each question one finds much disagreement among climatologists.

Such disagreement should be welcomed, for it is what science is all about....

"But at most was a political agreement to act and speak as if the major questions surrounding climate change had already been answered." another way to put that is that the world's political/media/academic elites have been living a lie.

This is also a good example of Thomas Sowell's dictum: The political left's favorite argument is that there is no argument.
