Respuesta :
The temperature of the Earth has risen by 0.14° F per decade. In the recent decade, the degree of warming has accelerated by more than twice that, to 0.32° F (0.18° C) per decade.
Scientists start by using temperature readings collected at various sites across the world to determine the global average temperature.
Absolute temperature readings are converted to temperature anomalies, or the discrepancy between the measured temperature and the long-term average temperature for each site and date, in order to track temperature changes.
The surface temperature data are independently analyzed by numerous independent research groups worldwide, and they all reveal a similar rising trend.
