摘要：Carbon emission is a problem of global concern because it scares humanity’s living. While CCS (carbon capture and sequestration/storage) strategy received global attention, some scholars argued that the present warming is just a natural step in a long range periodic change of climate. Here we show that it isn’t a natural phenomenon, nor is something con- trollable by the CCS strategy. Carbon emission is governed by an ecological rule of the earth: global carbon emission is linearly correlated to the world population when the latter is larger than 1.3 × 109. Therefore, birth control is an essential component of low carbon economy.
