I don't know where you get the 36 degrees from - it seems rather extreme. Do you mean 36 deg F = 20 deg C? Even 20 is not realistic, except perhaps for a very short period anomaly. In fact, the average temperature increase in the north pole area is little more than 4 degrees C. see
In general, the Earth's atmospheric heat distribution is to shunt heat polewards, and it is universally recognized that the lion's share of the temperature rise from climate change will occur in polar areas (for several reasons).
As to some places becoming unlivable, yes indeed, parts of the tropics and some places further north, are already heading towards that state. One thinks of North India where heat waves are now reaching the mid to high 40s (centigrade), which is the sort of temperature where people who can't afford air conditioning drop dead from heat exhaustion. This is likely to get worse.
Also, be aware that there are many +/- anomalies, including oceanic islands (high humidity) and coastal sub-Saharan Africa, where an increase of about 1.5 deg C above historic means are already making life difficult for some.
In the Arctic dramatic changes in lifestyle are also occurring, and will continue to do so at an accelerating rate. The 2 deg C limiting temperature rise, beloved of politicians (and which is already looking unattainable), is just a global average, within which the Arctic temperature rise could easily exceed 10 deg C.
