How do they calculate global temperature?
Hey man, I have been searching for the same thing! I have read there are urban and rural “temperature stations” located throughout the US that take surface level temperature measurements of the atmosphere. There are also oceanic ones. I’ve also read there are four major organizations doing these temperature reports, and all are reporting different trends. You can find all the data you could ever want but nothing on HOW it is used. This is critical because the heat necessary to change a given amount of atmosphere a given temperature is dependent on LOTS of things (temperature, pressure, composition, etc.). Also, it is important to know how the data collection/interpretation accounts for wind factors, and interference from various things in the urban areas. For oceanic measurements, how is heat from the Earth’s crust accounted for? In the midst of everything, do we assume the heat omitted from the sun is consistent? LOL????? The concept of a global average seems impossible. Some people s
