the "global warming" we're talking about these days only started happening in the 80s, are you retarded?

why would data from 120 000 years ago be relevant

the threat is a change of climate happening too quickly for us to adapt

>>16180244
Because of climate cycles. It was warmer 120,000 years ago, then cooler, and now it is warming again.

>>16180244
>the threat is a change of climate happening too quickly for us to adapt
Conjecture and speculation, by "experts" who want attention and crowds who can't reason. Also, bait thread.

We're in an ice age. What do you expect?

That there's ice in your freezer doesn't mean the door isn't open.

>>16182347
so you're saying that the earth's climate is cyclical and that projecting brief trends, such as the end of the little ice age, out to infinity is preposterous?

>>16180244
Because water evaporates in heat.

>>16182069
Depends. If Earth doesn't explode at some point like the former planet between Mars and Jupiter, then in 100 million years it will be the size of Jupiter. Then eventually the Earth will become a star like the sun.

If global warming is real, how come sea level was so much higher 120,000 years ago than it is now?

>>16193013

How would you know this?

>>16180244
That was so far back you're looking at the last interglacial, which was about two degrees warmer on average than our current interglacial. That kind of difference is why people freak out so much over global temperature rises of only one degree. The reason the last interglacial was warmer than our current one despite current CO2 emissions appears to be due to the earth's orbit being significantly more eccentric than it is now, about a +/-3.5% variance in the earth's distance to the sun compared to our current +/-1.7%

Isostatic uplift should displace enormous quantities of oceanic waters as coastal and sea floor regions expand to fill regions that were formerly filled with water and the result of that would be rising sea levels, yet there is no evidence that sea level is rising anywhere on the planet.

>>16180244
>how come sea level was so much higher 120,000 years ago than it is now?
You mean the Eemian interglacial period. It was caused by changes in Earth's orbit and axial tilt (Milankovitch cycles). These changes increased solar radiation in the Northern Hemisphere, leading to warmer temperatures and melting ice sheets.

>>16195433
How come there were more days over 90ºF 100 years ago?

>>16196540
It's called "cherry picking". They toyed with the metric until they got a graph that they liked. They like using "at all historically climatology network stations" because newer ones are built further North which gives you a cooling trend if you don't correct for it (which they of course don't).

Hi friend, Earth Scientist here.

Climate is fairly easy. The factors that determine it are as follows:

1. How much solar output there is: If the sun gets brighter the Earth gets warmer, if the sun gets dimmer, the Earth gets cooler.
2. The position of the continents:
Continents absorb energy much quicker than water and lose energy much quicker than water. Right now the Northern Hemisphere has more land than water and the Southern Hemisphere has more water than land. This is because of the following:
3. Changes in the Earth's orbit:
When Earth moves closer to the Sun it gets warmer, when the Earth moves away from the sun it gets cooler. Because the Earth's orbit is elliptical. If the Northern Hemisphere is facing the Sun when it's close to the Sun the Earth gets cooler. If the Southern Hemisphere is facing the Sun when it's closer to the Sun the Earth gets warmer. This is because land loses energy much quicker than water.
Earth's orbit goes through 3 changes.
It gets more or less elliptical over a 400,000 year cycle.
It's tilt becomes more or less pronounced from 22 to 24 degrees over a 40,000 year cycle
It changes it's precession (when it's summer or winter in the Northern or Southern Hemisphere) over a 25,000 year cycle.

Precession alters the climate most dramatically on short scales because as I said, if it's summer over the Southern Hemisphere when it's closest to the sun the Earth heats up because water absorbs water slower and releases it slower, thus making winters more mild and summers hotter and spreading that heat across the globe more evenly.

This is all called the "Milankovitch cycles".

4. Gases in the atmosphere:
First off, water vapor does not alter climate. It's a feedback, not a driver of climate. This is because the residence time of water is 1 week. If you somehow managed to evaporate all the oceans on Earth they would rain out in 1 week and return to the ocean. Water vapor can only respond to one of the other changes in climate.

>>16197070
The biggest actual climate gas is therefore not water vapor but:
#1. CO2
#2. Methane
#4. Nitrous Oxide

This is not up for debate.

5. Albedo.
Albedo determines how much sunlight is reflected back into space. The simplest way to describe this is dark things absorb more sunlight and white things reflect it. While this isn't perfectly accurate it's good enough. Most notably, bare rock, ground, water and plants absorb energy while snow and ice reflect it. The warmer it gets, the more snow melts, the warmer it gets and so forth, which is reversed during winter. However, as the climate warms all around winter becomes more mild, less snowfall and more ice melts, which aggravates the problem.

So. Your specific question. 120,000 years ago, while CO2 was lower than it is today, changes in Earth's orbit caused the Earth to be warmer. The sun is relatively stable over long time periods. It is not responsible for current climate trends. The Earth's continents haven't moved in millions of years and Milankovitch Cycles take thousands of years not the decades of change we've currently seen.

Your question is a natural one but I see that it's a dishonest one. You aren't looking for answers but making accusations. If you have any questions I would recommend you ask a climate scientist at your local university before coming to 4chan.

America got a boner lol

>>16197290
Great, what's wrong with it. Since you're an expert on Milankovitch Cycles. Where is the flaw?

>>16197070
>First off, water vapor does not alter climate. It's a feedback, not a driver of climate.
It's both, retard. Everything in the climate is both driver and feedback. The residence time is irrelevant.
> If you somehow managed to evaporate all the oceans on Earth they would rain out in 1 week and return to the ocean.
Maybe. But it would have a pretty major and disruptive effect on weather in the mean time.

>>16197076
>5. Albedo.
>Albedo determines how much sunlight is reflected back into space. The simplest way to describe this is dark things absorb more sunlight and white things reflect it.
White things like CLOUDS of WATER VAPOR have a major effect on albedo and thus surface conditions.
Have you been outside on a summer's day when the sky is clear vs overcast with thick cloud? Notice the difference in temperature?

>>16197348
you can't do calculus and you don't understand physics

>>16197358
How do you calculate albedo for an organic surface that absorbs sunlight and stores it as mass, sometime for hundreds of millions of years without ever reemitting the radiation at any frequency? Is that an albedo thats less than 0 because of the absorption is greater than what the blackest of black surfaces could muster or is the albedo great than 1 because the resultant cooling caused by the photosynthesis process is greater than what a completely reflective surface would produce?

>>16197378
thermodynamics has no solution for the organic matter issue

>>16180244

Regardless of it being true or not, big corps should be held liable for all the pollution they generate just because of muh money. Communism is bad, just as much as capitalism is bad; although capitalist countries are x100 scarier than Bolshevik Russia could have ever been.

Bolshevik Russia mass slaughtered 60 million of it's own citizens. That doesn't upset you because you're part of the insane enviro death cult. If you're so sure that human culture is bad for the planet then why aren't you killing yourself to help alleviate the problem?

>>16180244
There was a lot less CO2 in the atmosphere back then, yet sea levels were higher. That doesn't seem to dovetail with the idea that CO2 causes sea level to rise.

>>16203794
The fact that CO2 in Earth's atmosphere has increased by about 40% in the past 100 or so years with cause any change in sea level also proves that atmospheric CO2 does not cause sea level changes.

Rising sea levels isn't the only problem that comes with climate change though.
A big one is that extreme weather events like hurricanes, wildfires and storm surges will become (are becoming) more severe and more frequent. So areas that used to have enough time to recover between, let's say, two floods might not be able to anymore.
Also droughts are a factor which will cause massive waves of migrants to flee their home countries, so honestly I'm not sure why right wingers aren't all over preventing climate change
