Troppo Armadillo doesn’t have the huge audience of a megablog like Instapundit, but it certainly attracts the attention of more than a few key participants in important debates. The latest is Nir Shaviv, one of the two researchers whose paper on the influence of supernovae on climate generated this recent post. Shaviv’s fairly brief comments about global warming are well worth reading (for Gummo and Ken Miles especially).
