Global temperature refers to the average surface temperature of the Earth as a whole. It is an important aspect of climate change research, as changes in global temperature can have significant impacts on weather patterns, sea levels, ecosystems, and human societies. Scientists study global temperature trends by analyzing temperature data collected from weather stations, satellites, and other sources over long periods of time. This research helps to track past changes in global temperature, understand the causes of these changes, and predict future temperature trends. The study of global temperature is a key component of climate science and plays a critical role in informing policies and strategies to mitigate and adapt to climate change.
