Climate Change Detection/Attribution? Some Hope!

Curious situation on the website of the PCMDI – the “Program for Climate Model Diagnosis and Intercomparison”, at the Lawrence Livermore National Laboratory, with a stated mission:

to develop improved methods and tools for the diagnosis and intercomparison of general circulation models (GCMs) that simulate the global climate

Here’s what the PCMDI has to say about “devising robust statistical methods for climate-change detection/attribution“:

Coming soon…

That’s it.

Wow.

Sure.

Well, it looks like we will just have to be patient. We will be told how to detect and attribute climate change…one day, perhaps after some considerable amount of time will have ben spent in the frankly rather wasteful efforts of mostly comparing climate models to each other, rather than to the actual world.

p.s.: Applause to the PCMDI for their frankness:

The need for innovative analysis of GCM climate simulations is apparent, as increasingly more complex models are developed, while the disagreements among these simulations and relative to climate observations remain significant and poorly understood. The nature and causes of these disagreements must be accounted for in a systematic fashion in order to confidently use GCMs for simulation of putative global climate change.
