Yes, they claim it's getting worse .... because it is getting worse. You even admit ongoing warming in your own post, so how can you proclaim the models "failed' when you agree with their findings?  I have yet to see an alternative model that satisfactorily explains it as purely a natural process that excludes human influence, and again it's hard to buy the claims of the best model  (and actually pretty good models) being  "failed".  



The 30,000 scientist petition is long debunked - precisely 39 of those signatures were by self-identified climatologists, and those claimed credentials were never verified. The vast majority seems to have been laypeople rather than experts, so this claim is essentially meaningless.  It was also a decade ago.
