Why was the Arctic once warm?

Didn't you read the next paragraph, after the one you quoted?

"Of course, most credible scientists have dismissed Velikovsky's theories as pure fantasy. Nonetheless, the old psychiatrist with a penchant for conflating science and mythology achieved instant fame with his 1950 bestseller Worlds in Collision. He then went on to have a meteoric career as a lecturer, mystifying impressionable young minds with his own brand of anti-science."
​
Velikovsky's ideas were comprehensively debunked by scientists decades ago.

And eventually even Einstein came to agree with the majority of scientists it would seem.....
but he took the theory seriously for some time. A child's ball that is weighted on one spot will wobble when thrown in the air and it does seem as if the build up of ice on Antarctica is indeed growing and growing and growing. (Which is a good thing over the short term considering how much H2O melted off the world's glaciers and off Greenland in 2012 and 2019.)

Study: 2019 Sees Record Loss of Greenland Ice
By Pat Brennan,
NASA's Jet Propulsion Laboratory

Greenland set a new record for ice loss in 2019, shedding the most mass from its giant ice sheet in any year since at least 1948.

The large loss – 532 billion tons – is a stark reversal of the more moderate rate of melt seen in the previous two years. And it exceeds Greenland's previous record of 464 billion tons, set in 2012. The record melt will likely raise average global sea level by 1.5 millimeters. Using a hypothetical comparison, all the water combined would cover the entire stateof California in more than 4 feet (1.2 meters) of water.

The findings were published Aug. 20 in the journal Communications Earth & Environment.

"What I found interesting is such a high variability in the rate of loss for the Greenland Ice Sheet," said Alex Gardner, a researcher at NASA's Jet Propulsion Laboratory in Southern California and a coauthor of the study. "The years 2017 and 2018 were relatively mild after a decade of record losses, then 2019 came back to set a new record."

The Arctic is warming at roughly twice the rate of the globe as a whole. When extreme heat waves like this one strike, it stands out to everyone. Scientists are generally reluctant to say “We told you so,” but the record shows that we did

Opinion: That 100-degree day in the Arctic underscores how this region is now warming twice as fast as Earth

I agree with the theory that carbon should be put back in the soil. That way plants, animals and humans all benefit.

the smart people are concerned with climate change & sea level rise
your grandchildren will be living in boats at the current rate
& currently 60% of the worlds population live on the coast
you cant fit 50% of the world population into boats

what will the boat be run on ?
oil


where will 50% of the worlds population go to escape being drowned ?
they will need lots of oil to move their citys

where will all the concrete and steel and plastic come from to re build 40% of the worlds biggest citys ?

you obviously have not studied the hard science of CO2 and climate change

what is required is a stopping of CO2 being pumped into the atmosphere
the climate cant sustain it being pumped into the atmosphere to then be recycled by plants

the world cant plant enough plants to carbon sink it

so entire industrial commercial processes must be changed and quickly
to capture all their CO2
not "exchanged" in a swap in the atmosphere

But I do think that there is some good news.....
people are asking better questions than they were a decade or so ago.
