You (and I) weren't crazy: the Times did launch a new enviro-blog last Tuesday and suspend it on Thursday. It will return in early April, though, deputy innovation editor Aaron Curtiss tells me. He explained that the blog had been in the works before the new website regime decreed a moratorium on new blogs last month. Carbon Shift debuted anyway, without the usual higher-level review. Blogger Seth Jacobson's affiliation with the Green Coast Foundation was problematic to the Times news side, so he apparently intends to resign his post as executive director to continue with Carbon Shift. The blog also will no longer be a one-person operation but will receive contributions from Times science, environmental and business reporters, Curtiss says.
