Can you imagine the perilous consequences of the already alarming carbon dioxide levels, if it rises by 10 times today’s level? Siberia has already experienced it as huge volcanic eruptions occurred, leading to the worst mass extinction in the last half-billion years. Scientists believe that the deleterious atmospheric CO2 levels heated the surface of polar oceans up and stalled global ocean circulation. As a consequence, it starved marine life of oxygen wiping out 90 to 95 per cent of marine life and some 70 per cent of terrestrial life.
