Default Melting Ice exposes ancient virus

Quote:
A giant ancient virus was just uncovered in melting ice — and it won’t be the last

Let's get one thing out of the way really quickly: The ancient, giant virus recently discovered in melting Arctic ice is not going to kill you.

But here's the bad news: It's not the first ancient virus that scientists have found frozen — it's the fourth found since 2003. And you can be sure it won't be the last. And with climate change causing massive melts, it's not totally alarmist to suggest that something deadly might one day emerge from a long, icy sleep.

Yikes!

I suppose the key point is that all this melting ice just might actually expose a truly dangerous virus that has been long dormant.

Given the rate that we are melting ice on this planet, it seems like just a matter of time...

This seems to be a rather sensationalist and hyperbolic article. 30,000 years is nothing in evolutionary terms. Modern humans must have been in contact with these viri, survived that contact and possibly developed antigens against it. I'd be far more worried about the viri which are gotten from beneath the Antarctic ice where they have been for millions of years.
The size of the virus' genome doesn't matter either. There is no correlation between the number of genes an organism has and its organization, complexity and/or position in the hierarchy of life. There are tiny organisms and unremarkable plants with more genes than humans.

That global warming and its many, many undesirable consequences, though, will prove disastrous one way or another is of little doubt.

That's roughly half the time 'homo sapiens sapiens' have been present. That's not an insignificant time scale for human evolution.

That's an assumption on your part. Just because a virus may have existed 30,000 years ago, doesn't mean that humans MUST have encountered it. I'll admit that's likely, but not certain.

From what I've been reading, we won't have too long to wait to find out.

No doubt there will be many 'unexpected' consequences. There always are.

The sapiens sapiens designation is not the proper cut-off for this. The basic chemistry and DNA structure are probably very close for all archaic humans up to and possibly including Homo antecessor. That takes things back to possibly over a million years.

Not certain, no. Few things, if any, are in this context. A high degree of probability is sufficient in such a case.

The British Met expects the next to years to break all records again -globally- due to a combination and accumulation of factors:

Yep.
