Climate change is anticipated to cause declines in livestock production across North America  . Increases in extreme temperature raise the risk of livestock heat stress, disease and pest impacts . Projected aridification reduces forage production in the southwest USA and northern Mexico   and transforms grasslands into woody shrublands , while warmer and wetter conditions in the northern regions  may enhance rangeland production by extending growing seasons  . Increased CO2 will enhance production  but reduce forage quality  in US-NP and US-NW .
