Here is the prompt and satisfactory response I received late today:

We regret that your views were misrepresented on IPCCfacts.org, and have
removed the post.

The intent of the site is to follow the conversation around the IPCC
report and, where mischaracterizations about the report are made,
clearly and directly present the IPCC findings. We stand behind our
presentation of the IPCC report findings.

We regret the error.

Sincerely,

Joel Finkelstein
