02. What is the basic REALITY about climate change?

We are in danger of wrecking the climate for the whole planet which means wrecking the life-support  systems so that civilization collapses into violence, famine and disease.We have had 10,000 years of fairly stable climate since the last ice age.  We did not know that burning more and more fossil fuels was making the climate unstable but we do know now.   It is hard to believe but the science shows this reality in enormous detail and hard evidence.
