Farm animals responsible for quarter of global warming, study shows

Livestock are responsible for almost a quarter of all global warming, which is more than estimates based only on greenhouse gas emissions.

Climate change scientists say this a wake up call for New Zealand.

About half of the country's greenhouse gases come from stock, but a new calculation for global warming includes methane emissions.

Livestock were calculated to contribute about 23 per cent to global warming, by New Zealand Agricultural Greenhouse Gas Research Centre deputy director Dr Andy Reisinger​ and director Dr Harry Clark. They have just published a paper about how much livestock emissions contributed to global warming, in the scientific journal Global Change Biology.
