If global warming is real, how come sea level was so much higher 120,000 years ago than it is now?
>>16180244the "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 relevantthe threat is a change of climate happening too quickly for us to adapt
>>16180244Because 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 adaptConjecture and speculation, by "experts" who want attention and crowds who can't reason. Also, bait thread.
>>16180257Why was it warmer 120,000 years ago if atmospheric CO2 levels were so much lower back then than they are now?
>>16180244>He doesn't know about tectonics >He thinks shore line and sea level are the same thing
>>16180289CO2 doesn't impact global temperature, thats a fallacy.
>>16180330Says the american government agent
>>16180244>If global warming is real, how come sea level was so much higher 120,000 years ago than it is now?Earth is expanding, so sea level declines.
>>16182015redpill me on expanding earth, how much bigger is it going to get?

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.
>>16180244Because water evaporates in heat.
>>16182069Depends. 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.
>>16183431>projecting brief trends,yes, civilization included
>>16180289More humidity because all the wildlife wasn't destroyed
>>16183431>so you're saying that the earth's climate is cyclicalNo, earth's climate is determined by cause and effect. Not magic.
>>16180244>WTF WHY IS SOMETHING CHANGING??!!! I HATE CHANGE EVERYTHING NEEDS TO BE CONSTANThumans are retarded
>>16182357The glaciers need to hurry up. I want the sea levels to drop bigly so people can study all the stuff off the west coast of fl and in doggerland.
>>16184303>determinismDebunked in the 70s with Bell's Tests.
>>16180244Isostatic rebound
>>16185388Scandinavia is actually rising due to post-glacial rebound.
>>16180248>climate is changing too quickly for humans to adaptAre you retarded? That is literally impossible.
>>16187192they have no rational means of shilling global warming
>>16186809Sure it is. >oy vey stop noticing that sea level is going down goy!!!>sea level is rising, those measurements showing the opposite are antisemitic!!!meanwhile theres no evidence of sea level rising anywhere in the world. all those low lying pacific islands they were claiming would have disappeared by now are all still there, some of them have even increased in size
>>16185370>Theres more wilderness and wildlife now than there ever has been in the entire history of our speciesLol, 200m years ago that entire map would be green
>>16189208no it wouldn't have, there was nobody around to irrigate the arid regions of the planet back then
>>16180389>shore line and sea level aren't the same thing
>>16190699Found the retard.
>>16180248>too quickly to adapt We could adapt to rising sea levels. We just move further inland no? I understand that it will be costly but it won't doom the human race.
>>16191616theres no evidence that sea level is rising
>>16191616>we just move further inland no?Will you expropriate the poor rich folks owning those lands to make room for the coastal people?
>>16180289The timing of summer solstice coincided more closely with Earth's closest approach to the sun.
>>16192088I don't know I am not the policymaker. But it definitely wouldn't doom the human race or anything.
>>16192098Nothing will ever doom the human race, it's a fact. Something may doom civilization, but even that would be a worldwide cataclysm. The world will become nothing but people and their economically important animals. Hope you like the dog zoos.
>>16192058>vuosiYes, that's Finland. >>16186809
>>16185370This is an absolute and utter lie. Typical of conservatards.

>>16180244Not a warming-alarmist but... OP, you do realise you are talking about the Eemian interglacial, right? The Holocene-before-the-Holocene?Temperatures Eemian were similar to temperatures now.reed moar b4 commenting on /sci/, retard
>>16180244Human population only exploded in the early 1900s.>120,000 years ago.Are you braindead OP ?
>>16193155If global warming is real, how come sea level was so much higher 120,000 years ago than it is now?
>>16193013How would you know this?
>>16180244That 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%
>>16180248Low iq, low information reactionary people like you are why nothing ever changes for the positive
>He tried to conflate natural Milankovitch cycles with anthropogenic climate changeTry harder, you silly gubba.
>>16193013>>>/pol/
>>16186809>>16192998Isostatic 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.
>>16195433How come there were more days over 90ºF 100 years ago?

>>16180244Hi 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 cycleIt 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.
>>16197070The biggest actual climate gas is therefore not water vapor but:#1. CO2#2. Methane#4. Nitrous OxideThis 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
>>16192088You realize rich people live on the coast right? Or are you under the assumption that the rich live in fly over country? >>16192100>Nothing will ever doom the human race, it's a fact.....he doesn't know....>The Great Filter blocks your path
>>16197070you have zero knowledge of orbital mechanics and you can't even do basic math, so theres way you have any idea what you're talking about. you're just regurgitating memorized buzzwords from your propaganda textbooks even though you have no rational basis for believing that the propaganda you memorized is true.
>>16197290Great, 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?
>>16197348you can't do calculus and you don't understand physics
>>16197358How 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?
>>16197378thermodynamics has no solution for the organic matter issue
This video from 42 years ago says that most of Florida should be under water by now due to global warminghttps://youtu.be/JHD_7urJLvM
>>16198736they sure were wrong about that. why are scientists so stupid? their ridiculous predictions are always wrong
>>16180244I want to see Girthy Florida
>>16181061I'm in them, every sproutin' tree, every child of peaceEvery cloud and sea, you see with your eyesI see destruction and demise, corruption in disguise (That's right)From this fuckin' enterprise, now I'm sucked into your liesThrough Russel, not his musclesBut percussion he provides for me as a guide, y'all can see me now
>>16197358Dude, clouds are well understood in how they affect the climate. Now you're just coming up with excuses.>>16197368So you have no idea. Great. Thanks.
>>16199738you can't do calculus and you don't understand physics
>>16180244Stop noticing, goyim
>>16180244That explains why politicians keep on investing massively in waterfront real estate
>>16180244Sea level is still receding
>>16180244You idiot OP, climate change doesn't necessarily mean rising sea levels it just means that the sea level goes up and down randomly in random parts of the world. The proof of this are waves. They go up and down all over the place.
>>16188487Regardless 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.
>>16202527Bolshevik 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?
>>16180244There 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.
>>16203794The 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.
