Odd.
It seems odd for a group that (supposedly) wishes to avoid the controversy that is rife in climate science to choose a publishing venue that is almost bound to be controversial. There's nothing wrong with being open access and there's nothing wrong with being a new journal - all journals are new at some point. But a paper that is supposedly a sober review of existing data ought to be able to get published in a more established journal.
