Modern human activity is known to drive climate change, but global temperatures were already affected by farmers millennia before the Industrial Revolution. For years, scientists have been debating about the size of preindustrial warming effects caused by human activities. Now, according to Ruddiman et al., new evidence confirms that early agricultural greenhouse gas emissions had a large warming effect that slowed a natural cooling trend. | Modern human activity is known to drive climate change, but global temperatures were already affected by farmers millennia before the Industrial Revolution.
