Well that was during an ice age so I’d imagine so

I’d just thought it would be a lot colder considering it’s an ice age.

Guess I’m getting downvoted for not knowing how cold it was during the ice age. Well I do now

Is this interesting as its only 11 degrees, as there was an ice age 20k years ago, most people would expect it to be a lot more than 11?

The difference between covered in glaciers and no glaciers is very little. 6 degrees. Some think we're in the beginning of an ice age now and only global warming is holding it at bay.

Yep. The entire world doesn't need to be below freezing for massive glaciers to cover almost everything

The real crazy numbers come from when the entire Earth froze over (Snowball Earth) and the average temp at the equator was -10°F and global mean temperature would be -50°F.

The glaciers only reached about the middle of Pennsylavania, they didn't cover everything

That's pretty cool

It might be “only 11 degrees”, but that's across the whole planet. Water can hold an absurd amount of heat.

But that was my question, is the interesting part of this fact that its only 11 degrees?

Ha! I get it.

Pretty much.

We are in a cooling phase radiatively. But that is a slow process - some thousands of years before we go into an ice age. Global warming is not only counter-acting that, it's going well past to temperatures not seen for a million years or so.

But if Pennsylvania was 11 degrees cooler, most people wouldn't intuitively think that means glaciers

Global average was that much cooler. Not everywhere cools by the same amount. The further away from the equator, approximately, the more intense the cooling.

Same thing in reverse now. Global average up 1°C since 1880, but parts of the Arctic are over 4°C warmer.

Interestingly enough there is the hypothesized snowball Earth period which was about 700 million years ago where it is thought the average temperature for the planet was between -50C.

Ice ages occur every 100,000 years or so, so we’re due for another one.

Edit: apparently some people here don’t like reading facts.

We are coming out of an ice age

Yup, and you know what happens as we come out of the ice age.

It gets warmer

Breaking News: Ice Age was cold!

Folks don’t understand anything. How close like ice age was. How fucked our children are.

Lol

Glad it finally warmed up

They prefer to be called Glacial Periods, and I think you'll find that they aren't cold. Interglacial periods are hot.

You need to be more temperature sensitive.

Between -50c and what????

Yea you can't be doing that start and not

Hey

We’re having one in Iowa right now

Any science to support that outlandish statement? #sarcasm

We're currently in an "ice age" right now, the industrial revolution and the continuos pollution to follow is extending our current interglacial period

It's in the naaaame? 😒 It's also how we know it lasted ages /s

An interesting proposition would be what happens geologically when the earth heats up. Will we see a rise in volcanic activity again? What will happen if a super massive volcano erupts and leads to significant rapid cooling. The CO2 in the atmosphere won't dissipate in any relatively short amount of time so I would expect the Earth maybe enter a vicious cycle of rapid cooling and heating as both cycles feed into each other until the carbon dioxide is finally expunged. Just a conjecture though and would probably only happen on a longer timescale like 500-1000 years per cycle

Not sure how an increase in atmospheric temperature would cause an increase in volcanism...

I am not saying they would be correlated. Its purely conjecture. I can't say that there wont be geological affects on the earth though there certainly will be. I am just proposing if that the earths crust heated up it became a little more leaky to put it as basically as possible. More energetic. More tension between tectonic plates. Hell maybe the increased acidity in the ocean starts dissolving shit at the bottom of the ocean and causing steam pockets under massive pressure to literally push on earths magma with pressure unfathomable to us. Just conjecture.

1000 degrees.

Between -50c and -50d

How do they even know this? Is there a way to actually be accurate and tell? Or do they just get a ball park or guesstimate and say that “they’re SCIENTISTS” and we just believe it…

C'mon, this isn't nearly as bad as it was on NYE.

-DSM Metro

Yeah that's probably correct
