15 June 2015, Climate News Network, Long-lived CO2 warms world for many millennia. The heat given off by burning fossil fuels warms the Earth far less than the carbon dioxide emitted, which research shows traps the heat in the atmosphere for thousands of years.  Gun the engine, and the ignition of fossil fuel produces not just working energy but heat that dissipates quickly into the atmosphere. But it also produces carbon dioxide that dissipates into the atmosphere. And in less than two months, according to new research, that pulse of carbon dioxide will have engendered more heat for the planet than the original touch of the accelerator. Xiaochun Zhang and Ken Caldeira of the Carnegie Institution at Stanford, California, in the United States report in Geophysical Research Letters that the carbon dioxide warming exceeds the heat released by a single act of oil combustion in just 45 days. Light the gas in the cooking stove and the heating cost to the planet is exceeded in 59 days. Burn a lump of coal, and the atmosphere feels the greater heat in just 34 days. And in all three cases, the pulses of carbon dioxide will go on heating the planet – and on, and on. “Ultimately, the warming induced by carbon dioxide over the many thousands of years it remains in the atmosphere would exceed warming from combustion by a factor of 100,000 or more,” said Professor Caldeira.
