Is this not causing global warming?
9.9 trillion fahrenheit is is about 5.5 million celsius
For perspective the hottest NATURAL place on earth is the earths core at around 9400f (5200c)
Sure you could say it's only a very small area, but surely 9.9 trillion divvied among the earths area would still amount to a point of a celsius/fahrenheit or maybe even 1 or more, which is the kind of scale we talk about global warming at anyway
