Having re-positioned myself with regard to the who’s responsible argument concerning global warning, I wonder what people’s reaction is to UN Secretary General Ban Ki-moon’s challeng to act on the findings of the latest report on climate change: “Real and affordable ways to deal with the problem exist.”

The Intergovernmental Panel on Climate Change states that climate change is "unequivocal" and may bring "abrupt and irreversible" impacts, per BBC News. Mr Ban said, "Today the world's scientists have spoken clearly and with one voice. In Bali I expect the world's policymakers to do the same. I come to you humbled after seeing some of the most precious treasures of our planet threatened by humanity's own hand. All humanity must assume responsibility for these treasures."

Is this as more mumbo-jumbo designed to scare us and distract us from the real problems of the world, or, this time, has he highlighted the fact that we have a real and pressing problem?

"Approximately 20-30% of species assessed so far are likely to be at increased risk of extinction if increases in global average temperature exceed 1.5-2.5C,” per IPCC. But then, increased risk? What does that mean?
