Senator John Kerry has a nice piece in the Huffington Post laying out the need for immediate action on climate change in advance of his trip to Poznan next week for the UN-sponsored talks.

He situated the problem of climate policy within the context of a international crisis.  Of the national security problems facing the country, Kerry said, "none will be more global in its scope, more urgent in its stakes and timing, or more desperately in need of a complete policy overhaul than global climate change."

For a preview of Kerry '08 here is a link to a video of his speech at last year's meeting in Bali.
