Scientists are now very sure that global warming is a reality and we have only humans to blame for this occurrence.
A recent report by the Intergovernmental Panel on Climate Change (IPCC) seeks to underline the importance of sustainable action by policy makers and the public on climate change.
World Meteorological Organization Secretary General Michael Jarraud said, "It should serve as another wake-up call that our activities today will have a profound impact on society, not only for us, but for many generations to come."
Sir David King, former science advisor to Tony Blair had expressed the enormity of the problem in 2004 when he said, "In my view, climate change is the most severe problem that we are facing today, more serious even than the threat of terrorism."
It is also apt to quote Dr. Tim Flannery, who had said, "One problem facing humanity is now so urgent that, unless it is resolved in the next two decades, it will destroy our global civilization: the climate crisis."
