Technically speaking, are we still currently in an ice age?
Yes, technically we are still in an ice age, although in an inter glacial period of an ice age when the glaciers have retreated to the polar regions.
However, it is unusual for this planet to have polar ice caps, never mind two of them.
Through most of its geological history it has had no ice caps, or one ice cap at most.
When the dinosaurs were living here, the Arctic Ocean was as warm as the water in the South Pacific is today.
There were dinosaurs living in Antarctica, and forests growing on the Canadian Arctic Islands, which are treeless Arctic tundra today.
Most of Canada had a subtropical climate at that time.
On the other hand, it is hypothesized that at some points in the past the oceans froze as far as the equator, which is one reason for the slow evolution of life until the Cambrian era, when multicellular life appeared to explode under warmer conditions.
Having spent considerable time on glaciers, I have seen watermelon snow, red-tinged snow cause by algae growing in the snow.
Of course global warming alarmists are now panicking because they see this and think it is a crisis which will destroy humanity.
I think it is how life survived the Snowball Earth climates of the past. Yes, algae can grow in snow, if it has to. Complex creatures, not so much.
Don’t worry about the polar bears. They don’t really need ice to survive and have been through global warming before.
