Don’t give me that bull, our current warm spell started 25,000 years ago, the cold lasting for 125,000 years, cycling back and forth every 125,000 years.
I was going by the major ice ages, not the minor ones "At least five major ice ages have occurred throughout Earth’s history: the earliest was over 2 billion years ago, and the most recent one began approximately 3 million years ago and continues today (yes, we live in an ice age!)."
This source rounded up from 2.6 million

The start of the major ice age is much more relevant to your contention that humans lost their hair during an ice age, since that trend predates our 200,000 year old species.
Also, source for the temperature differences
Study Finds the Tropics Can Cool
Since the equator itself wasn't frozen over during the last ice age, major or minor, there wouldn't be ice cores from that area aside from high up mountains.
Standard evolutionary PR, to ignore the ice ages that have occurred every 125,000 years like clockwork.
-_- oh, like it is your standard PR to not even account for the fact that our species has been around for about 200,000 years and that we are still in an ice age, and you are thinking we lost our hair after our species already existed, or you don't think we have existed long enough to predate the minor ice age you are thinking of.
That, and I guess you think ice age means it couldn't be warm anywhere, which isn't correct.
We just came out of a little ice age about 2000 years ago that barely made it to -.6
-.6 what? Use units of measurement.
These conditions led to widespread crop failure, famine, and population decline. And that was only -.6 and lasted only a few years.
We'd already changed our original lifestyle and spread outside of our natural habitat long before that happened. Also, in case you didn't notice, that population decline didn't kill us off.
In between those brief warm spells it’s been fluctuating down to -10 and lasting for 100,000 years.
-10 what? Use units of measurement. Also, relative to what temperature?
Don’t try that it’s been balmy routine for 2.6 million years when the actual scientific evidence says just the opposite.
-_- we had a misunderstanding about which ice age was being talked about. I inferred that you had to be talking about one that predated our species, since the hair loss development in terms of evolution does predate us. I didn't actually think you could have possibly thought that evolution claimed our species started out as hairy as a gorilla.
Summary of my main points:
1. even during ice ages, it isn't super cold everywhere.
2. as it so happens, one of those not so cold areas is where our species first arose.
3. It wasn't darker during the ice age like you claimed; it's not like it would have produced more clouds to blot out the sun.
