Abstract
The increase in the concentration of greenhouse gases originated from burning fossil fuels, along with breeding, been appointed as the main causes of global climate change resulting from global warming in earth's atmosphere. These changes can cause serious impacts on the lives and livestock production mainly in tropical regions. Therefore, the aim with this work was to evaluate the effect of global warming on the climatological variables, thermal comfort index and animal production in the state of Paraiba. For this meteorological data from four meteorological stations by state and calculated the temperature humidity index used. The means analyzed from the difference between the normal period of 30 years (1961 to 1990) and the period of the last four years (2011-2015). The results showed that all regions of the state are suffering from climate change due to global warming and that there was an average elevation of ITU in recent years, indicating that changes in attitude should be intensified to allow the survival and productivity of animals does not become increasingly costly in the state.
