Physics World has managed to extract some brief comments from Wolfgang Wagner, the editor of Remote Sensing who resigned over the Spencer and Braswell paper:
I saw several basic problems [in the Spencer–Braswell paper], including that correlation does not imply causality, the fact that 10 years' of satellite data are not enough to come to such strong conclusions about the subtle and long-term changes in climate, and that, indeed, too little quantitative evidence was presented to support these strong claims,"
He also denies having any pressure put on him. Which is odd when one recalls his apology to Kevin Trenberth.
