The Sierra Club has crafted eight queries it would like to see Bush and Kerry hit with during Friday’s town-hall-style debate, and it’s asking you to vote on the best.  Currently top in the running:  “The Russian government recently announced that it will put the international global-warming treaty into effect by ratifying the Kyoto Protocol. The current administration has pulled the United States out of the agreement, even though this country accounts for 25 percent of the world’s global warming pollution. How will the United States do their part to curb global warming and stabilize the global climate?”

Meanwhile, a whole gaggle of earth-loving folks — from reverends and union types to bigwig scientists and a former head of the CIA — are petitioning [PDF] the Commission on Presidential Debates and the moderators of the two upcoming debates to “include questions about the candidates’ plans for reducing greenhouse gas emissions and promoting clean energy and clean vehicle technologies as urgent matters of both domestic and foreign policy.”
