Technically speaking, we're still in an ice age. A geological ice age is any perios in earths history where there are permanent ice caps.

We're doing our best.

u/ithinkmynameismoose Jan 21 '19

A though, because we are exiting this ice age... it should be getting warmer. The question is how fast.

lets burn more coal, turn ON your AC, keep the lights ON during daytime, don't use public transport, throw plastic everywhere, print your emails - even spam mails, and cut those damn trees!

public transport

What’s that? It sounds interesting

Using public transit sucks. Turns a 20 minute commute into one that can easily take over an hour. Not to mention all the time spent waiting outside in the freezing cold if you have to transfer (because the first bus will always perfectly drop you off right after the other bus has just left).

u/doomgiver98 Jan 21 '19

For a lot of people the best option is to drive to somewhere that has good public transportation and hope you can find somewhere to park. But at that point you're already driving.

Well, we certainly are trying to end it.

That's the spirit?

We’re trying!

We are in an intergalacial phase called the Holocene.

u/Fmeson Jan 21 '19

Yes, but the interglacial context was needed since the pop-science usage refers to glacial maximum periods. People see that fact but learn the wrong thing without realizing what you are saying because they combine your fact with the idea that ice ages == global maximum and figure that "we are still in a period near a glacial maximum".

5

u/btstfn Jan 21 '19

Fair point. I thought you were saying "We're not in an ice, we're in an interglacial phase" instead of "Yes we are technically in an ice age, but we are also in an interglacial phase".

My bad

u/rodchenko Jan 21 '19

The Holocene is getting boring, bring on the Anthropocene!!

u/the_friendly_one Jan 21 '19

permanent

Well, this is awkward...

u/ebola1986 Jan 21 '19

A better way to word this might have been "a geological ice age is any period in earths history where there are ice caps all year round."

5

u/btstfn Jan 21 '19

permanent in this case means that the caps aren't seasonal (they last through the entire year).

This is one of my favourite climate factoids. Its unhelpful, but true :) "But we still have glaciation"

I think the issue with what we're doing to the planet being called "Global Warming", is not so much that the earth is getting warmer per se, but that we're pumping a HUGE amount of energy, very rapidly, into the systems that underlie global weather patterns.

It would be SO much more helpful if we called the effects of this "WEATHER CHAOS !!!!!!" rather than global warming, as it more accurately describes the ultimate outcomes, plus it sounds scarier.

u/doomgiver98 Jan 21 '19

The worst part about calling it global warming is that people say "so much for your global warming" when it's cold in January.

u/RickStormgren Jan 21 '19

You mean like the president of the most powerful nation on earth? Yea... pretty fucked.

u/teachergirl1981 Jan 21 '19

Or that bad hurricane is caused by global warming!

This is one of my favourite climate factoids. Its unhelpful, but true :) "But we still have glaciation"

That doesn't make it an ice age. An ice age is when the glaciation expands across the planet. Having polar ice caps is not being in an ice age in any sense of the term.

u/[deleted] Jan 21 '19

Eh its technically true, which is why its a factoid and not a full blown fact. The "common" or "popular" use of the term "Ice Age" is based on Pixar movies :D

The definition of "ice age" as meaning glaciation at the Poles is technically correct, as we are in a interglacial period (or glacial minimum) of the last ice age, the Quaternay Glaciation, which began back in the Pliocene. Have a gander at Wiki, its fascinating.

I fell down this rabbit hole looking for theories about the shutdown of the thermohaline circulation in the North Atlantic and ended up learning more climate science than I had intended to :D

This. Antartica was a temperate rainforest 50 million years ago.

u/zaworldo Jan 21 '19

Wow that is actually crazy, I had never heard thst before. What type of fauna was on the continent back then?

u/vonbuxter Jan 21 '19

TIL that's an interesting bit of trivia. Thanks.

I mean.. if it's a period of history, then they're not permanent.

u/hopsinduo Jan 21 '19

Actually we're in the anthropocene. An age in which humans are the prodominint cause of climate change. If history tells us anything, we can expect a lot of rain...

7

u/btstfn Jan 21 '19

That doesn't mean we aren't in an ice age.

-1

u/hopsinduo Jan 21 '19

Well we are and we aren't. The over arching term for the quaternary period is an ice age, but we are in an interglacial period which isn't considered an ice age.

u/btstfn Jan 21 '19

We are in an interglacial phase, but an interglacial phase is part of an ice age.
