# Global warming and air temperature

The layman's question. Is there a maximum temperature that can be reached by air on Earth due to global warming? For example, one that would prevent living organisms from functioning? I read somewhere that with the increase of the sun's brightness by 10%, the average temperature on our planet will be 47 C. This, however, only for about 600 million years. Would global warming enable reaching such a high average temperature?

• Humans get in big trouble already at $40^\circ$C and high humidity. Global warming will increase the area where humans cannot work or live. – Pieter Jul 20 '18 at 13:23

There is, of course, a maximum temperature; we can't reach $\infty$°C. Venus may be close to the upper bound. But at that maximum temperature, life on Earth will be history.
