The Jorgenson et al. (2004) model includes additional features such as climate impacts on water supply and human health. Key market impacts associated with these scenarios and damage relationships were simulated using a detailed model of the US economy known as the Inter-temporal General Equilibrium Model (IGEM). IGEM integrates the changes predicted for each sector into an aggregate response by the entire economy. Of course, it cannot be any more accurate than the assumed relationships between climate and each sector.
Usually, bigger producing animals with larger metabolic heat have more trouble eliminating excess heat and are therefore more susceptible to heat stress (NRC, 1981). 2). Generally speaking all species show a decreasing rate of feed intake as temperature rises. For example, dairy cattle intake rates decline from 140 to 60 percent of intake at 18–20°C (the benchmark within each species’ thermoneutral zone) when temperature increases from 215°C to 40°C. Feedlot (beef) cattle intake rates decline from 105–115 to 80–50 percent of intake at 18–20°C when temperature increases from 218°C to 40°C.
