It's sort of hard to define exactly where the atmosphere ends and outer space begins (since the atmosphere gradually falls off as you go up in altitude), but one popular choice is the so - called «Karman line» at a height of 100 km (or around 62 miles) above sea level.

But that's actually an understatement by Gallup, since more than 97 % of the world's climatologists say that those carbon gases, which are given off by humans» burning of carbon - based fuels, are causing this planet's temperatures to rise over the long term, as those carbon gases accumulate in the atmosphere and also block the heat from being radiated back into outer space.
