Sentences with phrase «driven by methane»

During the early 2000s, environmental scientists studying methane emissions noticed something unexpected: the global concentrations of atmospheric methane (CH4)-- which had increased for decades, driven by methane emissions from fossil fuels and agriculture — inexplicably leveled off.
