The ice age goes away, former tundra and permafrost land becomes arable, food supplies increase, some animal species are lost, all in all Earth becomes more mammal friendly.
Here is truth about global warming:
Global warming is one-half of the climatic cycle of warming and cooling.
The earth's mean temperature cycles around the freezing point of water.
This is a completely natural phenomenon which has been going on since there has been water on this planet. It is driven by the sun.
Our planet is currently emerging from a 'mini ice age', so is
becoming warmer and may return to the point at which Greenland is again usable as farmland (as it has been in recorded history).
As the polar ice caps decrease, the amount of fresh water mixing with oceanic water will slow and perhaps stop the thermohaline cycle (the oceanic heat 'conveyor' which, among other things, keeps the U.S. east coast warm).
When this cycle slows/stops, the planet will cool again and begin to enter another ice age.
It's been happening for millions of years.
The worrisome and brutal predictions of drastic climate effects are based on computer models, NOT CLIMATE HISTORY.
As you probably know, computer models are not the most reliable of sources, especially when used to 'predict' chaotic systems such as weather.
Global warming/cooling, AKA 'climate change':
Humans did not cause it.
Humans cannot stop it.

no one knows we have do not have any TRUE global warming records to consult.
