Some good news:

• “U.S., 5 Nations to Cut Methane, Soot Emissions”

But also some bad news, and some just not-so-great-news, on the climate front:

• Uganda’s glaciers are disappearing (not really new news, but there are some great pictures on the BBC website).
• Also on the BBC website: Canada is “muzzling its scientists”
• I”m not sure whether this is good news, but Rio+20 “won’t be idealistic”. Allegedly it will be “realistic” and that is better.
