RC Rejects is a place to keep comments rejected from the Real Climate website, for one reason or another.
Posters there have found that very often their comments are rejected outright with no explanation. The reasons for this are not explicit, but interesting patterns emerge when one reviews a compendium of rejected posts.
RC Rejects invites those who have had posts rejected at RC to put those posts up here. Also, we note that posters on other sites often remark that they have had a post rejected, and put that post up on the other website. We invite anyone who sees such posts to put them up here.
