Mars likely to have enough oxygen to support life: study

To be fair, most of your Earth facts don't apply to the more inhospitable areas of Earth, where people live anyway. The Sahara and the Arctic both feature a breathable atmosphere. The Arctic is missing the other four items. The Sahara will let you feel sunlight on your face if you want, but it isn't really recommended.

"Breathable atmosphere" is a much bigger deal than everything else.

True, and heat. We can tolerate heat better than cold, also from a technical perspective. Heat can be used for energy production as well.

Our comfortable temperature is around 25°C. Let's set that as our baseline. In dry conditions we can bear about 90°C above that for a few minutes and only about 20°C above baseline sustained. In comparison we have many permanent settlements where days 75°C below baseline are a yearly occurrence.

If we talk about the more humid climates found in much of Europe and the US, the weaker members of our society start dying on days just 15°C above baseline.

I think we handle cold much better than heat.

From a technical perspective, no. It's easier to heat a dwelling from -100 degrees Celsius than to cool a dwelling from boiling, or above, temperatures.

To produce energy you need a temperature gradient.
