I'm almost out of woe-circuits

But it appears that, with global-warming warnings going unheeded by those whose attention is most needed, we may now have passed the tipping point in terms of melting of Arctic ice -- where the warming that has already occured sets off a self-reinforcing cycle of additional methane release and further melting of the ice floes and permafrost regions. Swamping of island nations and increased ferocity of tropical storms is only a fraction of what we'll see in coming decades.
