That’s not lice causing that scratching on your head (at least, we hope not) — it’s just a lot of head scratchers in today’s hot green news roundup. Stop the itch of curiosity right here!

1. Now here’s a question that’s been keeping millions up at night! Which is greener: Going into the refrigerator for a bottle of cold water or using the water dispenser on the fridge door? (Do those still exist?) Treehugger’s Ask Pablo says…um, why are you refrigerating your water?
2. What’s a ton of emitted carbon actually worth? The Institute for Policy Integrity consulted 144 leading economists and got…wildly disparate estimates from the pointyheads. (But 98% of them favored putting a price on the stuff to incentivize energy efficiency and innovation. Hat tip: CleanTechnica.)
3. How can you change a climate change denier’s mind? “The Psychology of Climate Change Communication,” a new report from Columbia University researchers, gives tips for advocates — don’t pile on the anxiety, and be honest about uncertainties. (The report also says people wonder why we can’t just reopen the ozone hole to release the build-up of greenhouse gases. Hat tip: Bright Green Blog.)
4. How many species have been listed as endangered by the Obama administration? Would you believe just one? That’s a much slower rate than that under President George W. Bush, reports Jeremy Hance at Mongabay.
5. 31 days to Copenhagen…what will happen? Today, the BBC’s Richard Black takes his best guess…and says get ready for some late night pizza deliveries and last-second deals. (There is good pizza in Copenhagen, isn’t there?)
