Most of what I’ve been hearing recently doesn’t make me optimistic that we can really limit global warming to 2 degrees. So I was all the more interested to read a press release distributed today at the climate talks in Bonn.A UNEP/WMO study says while reducing CO2 emissions continue to be a key factor, there are other measures which might help us keep below 2 degrees and benefit human health at the same time.
