The state of Texas is large and geographically complex. Its climate is determined by its geographical setting a third of the way from the Equator to the North Pole, bounded on its west by continent-scale mountains and on its southeast by the Gulf of Mexico, with a vast expanse of land stretching from its northern border to the Arctic Ocean. Precipitation generally increases from west to east, while temperature generally increases from north to south. Tornadoes are most likely in April and May, while hurricanes are a danger from June through September. As expected, temperatures have been increasing faster in Texas than the global average. Precipitation has trended upward in central and eastern Texas, but it is not clear if that will continue. Future changes in Texas climate will depend on future atmospheric greenhouse gas concentrations, the sensitivity of the climate to those gases, and the impacts of global climate changes on Texas weather patterns, as well as other factors such as natural variability and urbanization. While temperatures are expected to continue rising, future changes in extreme weather in Texas, such as with droughts, hurricanes, and wildfires, are multifaceted, but with a generally increased risk of the most extreme events.
