Answer 1

out of the 4 big failures that plague free-market capitalism, climate change was the most dangerous failure.

according to the science green house cas emmisons are an externality; it means our emmisons affect the life of other people. and if people are not able  pay for the consequences of their actions, the market failure happens.  This is the most significant market failure the world has seen. It is an externality that goes beyond those of ordinary congestion or pollution, although many of the same economic principles apply for its analysis.

This externality is different in 4 key ways that shape the whole policy story of a rational response. It is: global; long term; involves risks and uncertainties, and potentially involves significant and irreversible change.
