How about one where the Dew Point or Wet Bulb temperature never gets so high that human lungs literally stop working correctly and people overheat and die?
Humans can survive 130F in death valley as long as the dew point is below 95F.
However in India and Pakistan we are extremely close to a climate that is literally unlivable outdoors for weeks at a time.  Other places may follow if we don't start reducing CO2 emissions and doing a better job of capturing what's already out there.

So...climate change.

The concern is all the CO2 in the atmosphere acting as a greenhouse and heating up the planet.  But where is the CO2?  CO2 based on its specific gravity of 1.5 is heavier than nitrogen (.97) and oxygen (1.1).  Nitrogen is 78% of the atmosphere, oxygen 21%. With the exception of some diffusion effects, the CO2 should be closer to the ground than either of those gases.  Therefore, it's more likely to be recaptured and brought back to earth deposited in streams and oceans by atmospheric pressure and storms.  As the planet heats, more moisture will fill the atmosphere, creating the conditions for more and stronger storms, hurricanes, etc.  However, the CO2 will eventually be returned to earth.  The difference between rate and volume of return to earth vs. the rate and volume of dispersal into the atmosphere is the critical factor here.  But to say that we are going to reach this level of unlivable dew point is speculation at best.  Storms will take care of this, which is potentially a whole nother issue.  One positive by-product of this will be that deserts could end up being fertile again.

This assumes no major volcanic activity.  If that happens, then the earth as a whole cools a bit depending on the activity level.  Which may not be ideal for the moment, but again, the earth will adjust.
