Short summary
We gathered data from published sources to assess the effects of growing conditions on the nutritive quality of grasses which feed livestock. Nutritive quality is important for livestock productivity and methane production. We found that forage nutritive quality was reduced at higher temperatures. We estimate that cattle methane production may increase in future due to temperature-driven reductions in forage quality. This is a positive climate feedback that further increases global temperatures.
