Humanist Symposium #20 at Jyunri Kankei. Always my favorite blog carnival! This is the atheist blog carnival that's about positive aspects of atheism and humanism, rather than critiques of religion, and there's always good stuff in it.
Carnival of the Godless #92, also at Jyunri Kankei.
Skeptic's Circle #87 at Action Skeptics. It's the Dirty Limericks edition -- how can you resist?
Carnival of the Liberals #65 at Neural Gourmet. This is the CotL on skepticism and politics, and it's really, really neat.
