AI: Yes, The average surface temperature of Earth is indeed around 15°C (59°F). NASA uses similar methods to determine the temperature of Earth and other planets in our solar system. This method primarily relies on measuring the infrared radiation emitted by a planet, which is directly related to its temperature. Here’s a more detailed explanation Infrared Radiation Measurement: Planets emit infrared radiation (heat) based on their temperature. NASA instruments, like the Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope, can detect this radiation and measure its intensity at different wavelengths. Bolometersand Semiconductors: NASA employs various instruments for this purpose, including bolometers and semiconductor-based detectors, to measure the infrared radiation. Greenhouse Effect: Earth’s natural greenhouse effect, caused by atmospheric gases, plays a significant role in maintaining its relatively warm average temperature of 15°C. Comparison with Other Planets: The temperature measurement methods used for Earth are the same as those used for other planets in our solar system. For example, the average surface temperature of Venus, which has a dense atmosphere, is much higher than Earth’s due to a stronger greenhouse effect.

NASA Planetary Data

Similar temperatures were recorded in 1994 according to the WMO who published an average global temperatures taken from the six major data sets: NASA, NOAA, Hadley, British Met Office, CRU East Anglia and Berkley about 15.31 C. Remarkably only 0.31 C difference above the more accurate temperatures shown in planetary fact sheet that were first published several years beforehand.

Early Days for 15.31 C

The net result globally made 1995 the warmest year since records first were kept in 1856, says a provisional report issued by the British Meteorological Office and the University of East Anglia.Which went on to say that the average global temperature at 58.72 degrees Fahrenheit, (14.84 Celsius) was almost half a degree (0.47 C) less than what it had it had agreed to the year before at 15.31 C (59.56 F). Phil Jones, head of CRU East Anglia and co-author of the Hockey Stick graph took control in 1998 and convinced the authorities that the global temperature had “dropped” even further to the same temperature 58 F (14.44 C) as the Hockey Sick graph in 1998.

Earth Temperature in 1998 Is Reported at Record High

The above link to 1998 global temperature of 14.44 C gave them 30 years of gradual warming back up to 15.31 C, the same global temperature that the WMO, British and US scientists had all agreed to in 1987, 1994, 2024.
