Humans' 10,000 year warming habit
Humans have been warming the Earth's climate for the last 10,000 years, US scientist William Ruddiman claims.
The University of Virginia professor says agriculture has put greenhouse gases in the atmosphere, pushing up temperatures by about one Celsius.
This, he claims, has broadly balanced the cooling that should have come from a natural reduction in the Sun's heat reaching Earth over the same period.
The professor has presented his ideas to the American Geophysical Union.
The AGU is holding its annual autumn meeting here in San Francisco.
