Global warming is not just a modern issue, but has occurred numerous times over Earth's history, with one such event happening 304 million years ago during the Late Paleozoic Ice Age (which spanned from 340 to 290 million ...
Reducing methane emissions from livestock would benefit farmers and the environment. In a first step towards breeding low-methane-emitting cows, researchers from the University of Pennsylvania School of Veterinary Medicine ...
