Most of the viruses were previously unknown to us.

"Our research shows that both bacteria and viruses are archived in the layers of ice making up an ice core so these records should allow us to study such things as the evolution of microbes through time," Thompson told CNET.

The paper discusses how glaciers are shrinking due to global warming, a hallmark of human-exacerbated climate change, and says the melting will lead "the loss of those ancient, archived microbes and viruses."

"We know very little about viruses and microbes in these extreme environments, and what is actually there," said Thompson
