Global warming is no longer about warming



It had to happen. Even Warmists have finally noticed that the globe is NOT warming, contrary to their past prophecies. So by some strange twist they claim that there are OTHER reasons for believing in global warming. It sound like loony bin stuff to me but here is part of it:

In reality, the correlation between global mean temperature and carbon dioxide over the 20th century forms an important, but very small part of the evidence for a human role in climate change.

Our assessment of the future risk from the continued build up of greenhouse gases in the atmosphere is even less informed by 20th century changes in global mean temperature.

For example, our understanding of the greenhouse effect – the link between greenhouse gas concentrations and global surface air temperature – is based primarily on our fundamental understanding of mathematics, physics, astronomy and chemistry.

Much of this science is textbook material that is at least a century old and does not rely on the recent climate record.

For example, it is a scientific fact that Venus, the planet most similar to Earth in our solar system, experiences surface temperatures of nearly 500 degrees Celsius due to its atmosphere being heavily laden with greenhouse gases. [The fool has obviously never heard of adiabatics. The high surface temperature of Venus is ENTIRELY explicable by the greater atmospheric pressure of the huge Venusian atmosphere]

Back on Earth, that fundamental understanding of the physics of radiation, combined with our understanding of climate change from the geological record, clearly demonstrates that increasing greenhouse gas concentrations will inevitably drive global warming.

Dusting for climate fingerprints

The observations we have taken since the start of 20th century have confirmed our fundamental understanding of the climate system.

While the climate system is very complex, observations have shown that our formulation of the physics of the atmosphere and oceans is largely correct, and ever improving.

Most importantly, the observations have confirmed that human activities, in particular a 40% increase in atmospheric carbon dioxide concentrations since the late 19th century, have had a discernible and significant impact on the climate system already.

In the field known as detection and attribution of climate change, scientists use indicators known as fingerprints of climate change.

These fingerprints show the entire climate system has changed in ways that are consistent with increasing greenhouse gases and an enhanced greenhouse effect. They also show that recent, long term changes are inconsistent with a range of natural causes.

Many more vague and unreferenced assertions here. It's one big wriggle -- an attempt to wriggle out of the fact that the bottom line of their theory -- a significant rise in average global thermometer readings -- is just not there.

BTW: The author above is Karl Braganza, a Kung Fu devotee (I kid you not) from Australia's Bureau of Meteorology. I suppose that I had better watch out that he doesn't come and Kung Fu me
