Climate Change - Science Morphing to Politics

David Janes is again on to the misrepresentations held out as scientific truth by global warming / climate change alarmists.

Here is a link to a whole bunch of David's posts on the subjects. (if I recall correctly, Dave cut his programing teeth in the weather mapping trade)

A: Yes, it would be absurd.”"

Now, finally, we check the actual science.

Who made the comment quoted above (that Katrina wasn't provably because of GW effects), but, now read within the context, the scientist is making a point that statistical analysis isn't possible specifically in the USA case because of insufficient data. However, he points out that this is a problem with the bounding of the question (of whether the case of the _USA_ is getting worse hurricanes because of CO2 _globally_. This begets nonsense, because numeric records aren't around to answer the question. However:

"Q: OK, maybe we won’t see global warming effects in landfalling hurricanes for another 50 years or so, but shouldn’t we still be worried about it?

A: [. . .] On the other hand, if one’s view is not confined to the U.S. but is global, and/or one’s time horizon is more than 50 years, global warming may indeed begin to have a discernible influence on hurricane damage, especially when coupled with projected increases in sea level."

So, what we have is that a person familiar with the data, who believes that global warming is happening and unquestioningly anthropogenic (check the link).

It's interesting that a statement on subtle technical level about a particular aspect of the impossible to satisfy require to politically frame/bound climate science is the one thing that is reproduced, minus all this context and commentary, and that this is what makes the statement change in reference (meaning), and that each website reproducing these ideas creates a hall of mirrors, where the meanings are changed, amplified and at each step gain in scope and level of abstraction. Finally, we have arrived at statements antithetical to the views of the one person expert enough to understand the subject.

So going back to the source and reading through it in context, we see that what was originally a comment about USA _statistics_, was quoted and adopted and passed along to support a view about science reporting, to climate science, to global climate change by this site.

. . .now, back over to politics?
