Big news on greenhouse gases from Rwanda!

After 7 years of negotiation, an agreement that controls the use of HFCs was signed in Rwanda this week.  HFCs are a class of chemical used in refrigeration and cooling.  Although they're only a tiny fraction of the worldwide greenhouse gas emissions, they pack a big punch when it comes to climate change -- they can have over 1000 times the heat-trapping potential of CO2!  Next week, I'll post about the ozone layer, climate change, CFCs and HFCs.  For now, check out this article about this important agreement!
