DeSmog fans will likely know about Tim Lambert at Deltoid – a smart Australian scientist who does fabulous work debunking some of the ridiculous denier talking points. But he has recently been pointing to some outspoken scientist contributors who are also raising the bar on climate debate: Robert Grumbine (Penguindreams ) at MoreGrumbineScience, and Tamino, who plays the deniers for fools at Open Mind. (Hat tip to VJ).

These guys are adding significantly to the quality science debunking that we have come to expect from RealClimate, the kind of stuff that leaves the deniers sputtering because, well, it’s all about science and they’re, well, not.
