NASA has used a forecasting tool to determine which cities they believe will be flooded first if ice sheets end up completely melting. The tool takes fundamental factors into consideration such as gravity and orbit.

These factors give a clear indication as to how the melted ice would be distributed on a global scale. “This provides, for each city, a picture of which glaciers, ice sheets, [and] ice caps are of specific importance,” researchers claim.

Researchers at NASA’s Jet Propulsion Laboratory, California, developed the forecasting device and have published their results in the Science Advances journal.

“Cities and countries attempt to build plans to mitigate flooding,” Senior Scientist Dr. Erik Ivins said. “They have to be thinking about 100 years in the future and they want to assess risk in the same way that insurance companies do.”

Ivins believes that the forecaster gives planners a clear indication as to which ice sheets they should be most concerned about. For example, the north-western region of the Greenland ice sheet could severely affect sea levels in and around London.

However, the entirety of the Greenland’s north and east may heavily affect east coast cities such as New York. As far as the southern hemisphere is concerned, the northwest and northeast coasts of Antartica are likely to affect cities in Australia like Sydney.

Another leader of NASA’s Jet Propulsion Laboratory, Dr. Eric Larour, believes there are three factors that heavily determine the sea-level transitions around the globe, with gravity being the most significant.

“These [ice sheets] are huge masses that exert an attraction on the ocean,” Larour said. “When the ice shrinks, that attraction diminishes – and the sea will move away from that mass.”

The planet’s rotation is another key factor. “You can think of the Earth as a spinning top,” Larour said. “As it spins it wobbles and as masses on its surface change, that wobble also changes. That, in turn, redistributes water around the Earth.”

With social media at our fingertips, you would think that people would be a little more careful when it comes to being jerks. So why is it then that there are still so many people who get called out for being a jerk or doing pretty jerky things? We are not sure, but here are 45 messed up examples.

Retail workers see a lot of crazy stuff. Some of it funny, some of it disturbing, and some of it just plain messed up! Most people understand that you have to change your baby, and that is why there are these places called bathrooms. So why do some parents feel entitled to just do it anywhere? On a stack of nicely folded jeans that took time and effort and was waiting for some other mother to buy for her tyke! Seriously? One misstep, and that is a stack of jeans that will never be the same.

When there is only one person to clean a facility, you should be very kind to them. After all, they keep you living in cleanliness and not in a heaping mountain of filth. The kids of this college dorm don’t understand that and have opted to be lazy. Who needs to walk to the bathroom when you have an empty bottle, right? After finding these bottles in the garbage, the janitor decided to leave a note and this sink full of bottles filled with pee. The note just kindly asked for them to stop doing this as it gets pretty heavy to carry the trash bags. It doesn’t seem like an unreasonable request!

There are enough fears of germs in the world without having to worry if someone has stuck their mouth on the food you are looking to bring home and enjoy. Who thought it was a good idea to start licking ice cream that you are not buying. This has become a trend, even catching some very famous people in this type of shenanigans. But what it boils down to is this isn’t funny; this is just gross… so stop it!

The people who work in the shops are not your momma! And that is who should have been paying attention while the children destroyed this thrift store! A thrift store is known for being kind of eclectic and isn’t always the best organized, but that doesn’t mean you can let your kids tear it apart. Remember folks, there are people who work there that are left with this mess when you leave. Be kind and pick up after your kids.

A kid’s soccer field is not the place for you to test out your new tires. This playground was torn up after a rainstorm by someone who must have thought it was SUNDAY… SUNDAY… SUNDAY! This is just messed up! This is a place that is kept neat and tidy through public funds for the kids of the neighborhood to have someplace to play. Who would think that it was okay to do donuts and rip up the field!?

Diapers seem to be a problem for a lot of people to figure out where to dispose of them. (There are quite a few examples of how not to on our list.) There are just some things that should be common sense. One of those is that you do not throw your dirty diaper onto a tray of dishes. Even if you are planning to throw it away, it is still pretty gross and not very sanitary.

There are a lot of reasons that children should not be left to their own devices. This may be one of the best examples ever documented. Who knows how this happened? However, the parents or adults in charge of these kids should really have been paying attention. Now the poor customer service workers are going to have to clean it all up, and the other kids will have to wait to find their special toy. That’s just not nice.

Airplanes are one of the best places to find people acting like jerks. It is like all manners and common sense stay on the ground as you ascend into the sky. There are so many things about this picture that are just wrong. Climbing on chairs and treating the airplane like it is a jungle gym, though, is probably the biggest jerk move you can make. This will affect everyone around you and make their trip uncomfortable. Also, this child has no shoes on! Another problem all on its own…

It’s bad enough when people do this when they are on the streets but in a line to get onto a bus!? Come on, that is just a poor decision. This woman thinks that if she stands and moves on this side of the line that eventually someone will let her in. This is just rude! Why would you believe that people who have been waiting in line and following the rules are going to let you just sneak in?

Grocery shopping can be very exhausting, and so you may need to find a place to rest, but does it have to be on food that others will be looking to purchase? This woman couldn’t wait to get to the car or use her cart as a way to take a load off. No, that would be too easy! Instead, she found an open place that she thought would be good to rest. Unfortunately, it just happens to be on the apple cart.

There are tons of memorial statues across the globe that are placed in parks. These are monuments to memorialize people and events, not to be a playground or kids. This war memorial is for the women who fought in the Vietnam War and is meant to help us remember their sacrifice. It is not, on the other hand, a jungle gym for the kiddies, so stop your kids from being jerks.

Consideration seems to go out the window when you get into those moving metal boxes. This is a prime example. Other people have a place to go and people to see, but because these jerks think their schedule and lives are more important, they don’t seem to care. This is not only inconsiderate but dangerous as well. So wait for your turn! Where you’re going won’t be moving anytime soon.

Sometimes as you get older, your joints and muscles become achy and hurt. So getting down on your knees and looking for anything could be a challenge. But this is not right! This is not only inconsiderate but dangerous as well. So wait for your turn! Where you’re going won’t be moving anytime soon.

Nature is meant for everyone to enjoy. This is not very enjoyable to come upon as you are breathing in that fresh… or not so fresh air. Hiking is good exercise and a way to spend some quality time with the little ones. When doing this, though, hikers should make sure to leave the woods the way they found them. That means picking up after yourself and not answering that age-old question if a baby poops in the woods does it make a sound. It doesn’t, but it sure leaves an environmental impact.

There are a lot of towns that have decided to help lessen their carbon footprint. In these cities, there are often bike or scooter rentals you can take advantage of. Who knew there were amphibious options as well?! Taking the time to throw all of these motorized scooters into the lake was just mean. Even if the perpetrators don’t believe in climate change, they should still leave these for those that do.

Clearly, the woman is tired of being told she is always late to pick her little ballerina up but does she have to be a fire hazard to prove a point. The parents behind this woman are certainly annoyed with the fact that not only is she blocking the door but hogging the best seat outside of the house. Surprisingly, instead of saying something, the parents took to social media to complain about their predicament. I hope she follows them so she will get the message.

This young woman thinks she’s in an old west saloon where throwing your shells on the floor is acceptable. Another example of how people lose their minds when flying and let all common courtesy go out the window. It is pretty simple to just ask for a plastic bag to discard your shells, but then again, maybe she’s afraid they’ll charge her. They won’t, but they will judge her, and so will everyone else that has to walk up that aisle.

Travel can be challenging and exhausting. So when there is a layover, it is perfectly understandable to catch a few zzz’s, but there is a right way and a wrong way. Welcome to the wrong way! Other travelers need some sleep too. So try not to be as big a jerk as these guys and sleep sitting up or on the ground so that everyone has access to get a little nap in.

There is just something that can be used to explain that you are bad at driving. This is not only an offensive sticker, but it clearly shows that you’re kind of a jerk. Is your child behind the wheel? Then the poor use of your blinker and erratic driving can’t be explained away because your child is developmentally challenged. This is a sticker that, in its essence, shows just how much of a jerk you are.

Taking care of public property and land is not an easy thing to do, and so when something like this happens, it affects everyone and everything in the park. Assuming this was some sort of gender reveal party leftover, congratulations, it’s a boy. Now pick up your mess so that everyone can enjoy the park and some poor squirrel doesn’t choke to death. No one wants squirrel murder on their conscience!

The servers and staff members at restaurants, even fast food establishments, are not your mothers. So please do not disrespect them like this man. Assuming this was some sort of gender reveal party leftover, congratulations, it’s a boy. Now pick up your mess so that everyone can enjoy the park and some poor squirrel doesn’t choke to death. No one wants squirrel murder on their conscience!

Please take all your trash with you, and we hope you enjoy your movie. This is a PSA before the movie, right? This is a messed up thing to see when the light comes up. For the ushers that have to rush to clean up your mess before the next batch of customers, this seems like a test of their skills and patience. Plus, the next movie can’t start until they are done, so don’t be a jerk and mess up the schedule and the viewing pleasure of the next batch of people. Just pick your trash up!

Lazy! That is what comes to mind when you see something like this. Unless you are running from zombies in the apocalypse, there is no reason to be such a big jerk. Even in a zombie apocalypse, how hard would it be to get that trash into the trash can that is like three feet away as you run for your life. The answer is not hard!

Another fine example of diaper disposal. It’s not like there are these things called garbage cans anywhere in the world. Where was this child changed? On the hood of the car? If not, that means that the parent just didn’t want whatever gift was left in the diaper in their car. That’s understandable, but couldn’t they have walked over to that trash can so that it wouldn’t be super-heated in the noonday sun!?

If there is a helicopter with a giant white cross at the end of a sidewalk, the odds are that you shouldn’t park there! Not sure what this person was thinking, but blocking access to the helipad for a hospital could lead to some very serious ramifications. But I guess if your emergency is more important than someone else’s, then this parking job makes sense. No need to worry about other people, they will be alright, you just do you.

Disneyland is the happiest place in the world, and to make things better, they have cool Lego statues like this one of Belle & Beast, but for how long? This dad clearly has had a long day and just needed a little time to check out what was going on in the world. But letting your kids take apart a piece of work that took hours to do is not the way to get a little time to yourself. Not only did some artists take the time to create this masterpiece, but other kids would like to enjoy it as well.

Can we say, hypertension anyone? This kid is getting his daily dose of sodium, and no one seems to be noticing. This is one of the reasons that cellphones should be put away when having a small child in an eating establishment. Chit chatting away, this parent didn’t notice that their child was licking and eating the salt from every table around them. This is not only disturbing for other customers but could be a health risk for the child. Someone get this child some water, he is going to need it.

It’s just a game, bro! Calm down! No-one is going to the big leagues from this little league game! This field apparently has had some issues with some very serious backseat coaching and felt it necessary to lay some ground rules down. Some parents take youth sports just a little too seriously. This can lead to screaming and even fights in the stands. Way to teach the little one’s good sportsmanship! Just calm down, you jerk, and let your kid have some fun.

There are designated places to change your child’s diaper, and none of those are in the middle of breakfast right on the table you just finished eating on. It might be different if you were in your own booth, but when you are at a communal style table, laying your child down to change a diaper no matter the contents of the diaper is just not very friendly.

It takes a lot to get ready for a tutoring session or to teach a child at home. You have to be organized and prepared, and this desk definitely looks like it is. Too bad someone wasn’t considerate enough to let them know that they weren’t going to be coming today. This is just one that is common courtesy. Save your tutor or teacher some work and allow them to have a little of their personal time back.

Some apartments have their inhabitants pay for parking spots, which means that if you park, or in some cases, partially park in their spot, you are costing your neighbors their hard-earned money. Imagine coming home and being so excited to get into your apartment and relax after a hard day of work. Then you pull up to see this. Do you pull in and potentially scratch their and your car, or do you post on social and curse into the wind? Either way, the person who parked this way is not being a good neighbor.

If your child stays home because they’re sick, there is no better way to waste the day than at Ikea, right? In order to not be a jerk, you should probably leave the kid at home, especially when they are home with measles. Exposing the workers and other customers to any contagious disease is just not only dangerous but just plain irresponsible.

Many mothers have told their children for years to keep their hands to themselves. Maybe they should have been saying keep your hands and feet to yourself. Most people agree that one of the worst things to experience is that flight where you are seated next to someone that removes their shoes or likes to do something like this. The thing that makes this disturbing is that those feet really need to be cleaned.

When did being a parent make it right to act like a jerk!? Parking like this is not right and then slapping a sticker on your car to rationalize why you thought it was is just plain wrong. Some might say at least they gave you warnings, but most would say stay in your space. Parking like this doesn’t insure anyone will abide by your rules of not parking too close. There is a reason there are two lines.

There is nothing like a neighbor that does archery as a pastime. Though it might be a problem if this keeps happening. A neighbor that has interesting hobbies means that there will always be something to talk about. However, if there is a constant fear of being impaled by one of their stray shots, this may make them less entertaining.

School events are so much fun, especially when the little ones are young. So it is easy to see why some parents get a little anxious and overzealous. However, other parents want to see their little guy or gal first and wave back and forth as they try to remember those words. So try to be less of a jerk and record from a low angle so the other proud parents can get a good view.

The heat of the summer can be murder, and having an extra fan in a room can help keep the air circulating. This will help keep everybody cool unless… This woman must be experiencing one heck of a hot flash, but that doesn’t give her the right to hog all the air. This is just not cool and something that makes her look like one giant jerk.

A nice party in the park could be a good way to celebrate your kids birthday, graduation, or whatever major events they have going on. The planning is grueling, but the clean up can be quite the challenge too. Maybe that’s why these party planners just left the confetti and balloons all over. But leaving this for someone else to pick up is not cool man! Not cool at all.

Displays in stores are made to give the customers access to feeling and testing how the products work and feel. This is especially important in the tech industry. But sometimes children or big kids think something like this is funny… There is one key to making an effective display, in this case, several keys. So removing them is a little bit of a jerky thing to do.

Libraries may not be getting as much use as they used to, but they still do see a little bit of traffic. This library has seen some action recently. They are still public areas, and leaving them in this state of affairs is not very nice. Just like when you turn your books in, make sure that the space you use is clean and tidy so that everyone else can enjoy their quiet time with a good book.

At the end of a long workday, there is nothing better than coming home and putting your feet up on the couch. That being said, we’re not sure that this is the most appropriate way to “wind-down.” In fact, this woman is preventing other passengers from relaxing after their hard day’s work. We feel like a couple of people probably pointed out that this was a jerk move, and in return, she just rolled her eyes and continued scrolling through her news feed. The worst part about this is that she had the guts to take off her shoes!

This looks like the butt end of a bet gone wrong – both sides lost this one. We’re guessing one of the housemates living in this apartment got sick of being the only one taking out the trash, so they decided to stop – triggering the roommate that was unaware of his ways. That’s where the bet part of this comes in after each side realized that the other side wasn’t planning on caving – they left it there. The result was obviously a disgusting pile of trash.

If you were to look up the word “jerk” in the dictionary, you would most likely see this photo next to the definition. We’re sure we’re not the only ones to step on wet pavement before, noticing our mistake we’ve quickly jumped off, as not to ruin the construction workers’ hard work! This person stepped on the wet pavement, and instead of stepping off, they decided to decorate the pavement with hundreds of footsteps. We can’t help but wonder why – after all, they probably ruined their shoes!

The only excuse for leaving a movie theater looking like this is if this is a crime scene of a horror film, one so scary, every time something happened, the audience jumped and spilled their popcorn. Even so, it doesn’t explain all the excess trash that was left in the theater. Movie theater workers, we bet you have to go through this every time the movie fades to black, and the audience leaves the room. We’re sorry on behalf of everyone who has ever watched a movie at the theater – we promise we’ll be better

Sometimes fathers can be real jerks – or was it the kid who was the jerk, and this was his father’s way of teaching them a lesson? We’re going to go with the latter. We’re guessing this pop asked his kids to clean up the house multiple times, receiving the same reply every time he asked, “LATER!” Well, kids, later is here, and there is no getting out of this one. It’s high time you start cleaning up after yourselves!

We’re not sure which car is to blame for this one, but whoever parked a little too close to its neighboring car is a jerk! Luckily for both sides, they seem to have big enough cars that they’ll have no trouble getting in and out of their cars from a different door – but either way, this isn’t the most pleasant way to reach your car after a shopping spree. We hope the white car reached their car first – making it easier for the blue one to pull out.

Reading library books is fun – sometimes you get a little surprise, a highlighted paragraph that the person read before you resonated with. Other times, you’ll even flip through the book and see some sentences – perhaps a thought a fellow bookworm had. Imagine opening a book you have been dying to read for years and landing on this first page. There is no way around it, the book is forever ruined for you. Would you continue reading? Or just close the book and hand it back to the library?

This is the best way to call out a jerk – just paint their house. Yea, not in the way you would want your house to be painted. Write them an open letter explaining exactly what happened and why they deserved this. Apparently, Terry didn’t pay the guy that painted his house, so instead of asking for his money, the genius painter gave Terry an extra paint job. What do you think is written underneath the word “bill”? We’re dying to know!

Yes, lady, this is the bun section, but that does not mean that you can sit your buns down on it. We get that waiting in line at the deli is not fun. It may even be tedious, but that does not mean that this is an excuse to sit and wait on bread. It isn’t an excuse to sit on any product for that matter. We’re guessing she turned all the bread into flatbread, so at least there is that?

Have your lips ever been so dry that when you try and smile, they crack a bit? Yea, we’ve all been there. This savage put a glue stick in the lip balm drawer. We can just imagine little Jenny picking a random lip balm (Jenny is five-years-old and does not know how to read so she wouldn’t know the difference), but blue is her favorite color, so picked the big, blue chapstick and quickly learned that she had made a big mistake.

When there is an arrangement of cookies in front of you, it’s hard to decide which one you want so why not eat them all? Not only did this person bite every cookie, but they also put them back. Jerk move? This is a true cookie monster. We are sure that this was intentional, they took a perfect crescent-shaped bite out of each cookie and then strategically placed them back onto the plate.

Convenient stores have interesting ways to get you to put a couple of coins in their tip jar. This is by far the most interesting tip jar we’ve seen in a while. They take their tips very seriously – they even printed a picture of the woman that stole their previous tip jar. We’re going to keep our eyes peeled for a lady with bright pink hair and a horrific striped shirt! We’re glad they looked for her in the security camera, calling her out!

Unfortunately, we don’t live in a world where people go out of their way to make sure they aren’t jerks. Everywhere you go, there is probably a jerk hiding out, waiting for their next move. This is the perfect example of that – at first glance, it looks like someone innocently parked their car in the parking lot of the grocery store, but then you notice there is blue paint, could it be? Yes! This person parked in a handicapped spot! To make matters worse, you’ll see they parked in two handicapped spots. This has us shaking our heads.

Now that we’ve seen this, we don’t think we’re ever going to be able to drink water from an unknown source ever again, let alone a drinking fountain. This is simply disgusting, and we’re glad someone caught this jerk on camera, now we know to never, ever touch a drinking fountain at the park again. We get that this guy had good intentions. He just wanted to wash his pup up…the only problem is, he disregarded everyone else at this park and their needs.

We love a good office rivalry, but whoever stole Jim’s beloved cup is a real jerk. So is the person that wants to buy the cup for $10. We’re guessing this is a part of some office joke that we simply do not understand. Our main question is, why does it look like they wrote this on a piece of toilet paper? Was it an undercover mission, they had to write their bribery note in the bathroom so that no one would see?

It is hard to keep children entertained, but that doesn’t mean you have to bother those trying to have a nice meal with your friends or family. Try giving them coloring books or a book. Having them tuned in to their favorite cartoons or watching YouTube is not the way. This is especially true if you are letting them watch without headphones. The noise of the restaurant will cause them to turn it up, and the louder the volume, the more of a jerk you will look like to the rest of the room.

One of the best ways to spend a rainy day is walking through a beautiful botanical garden. You will be able to see amazing plants and flowers that are not indigenous to your area. But there are paths, so this woman is definitely being a jerk. No matter how mad a person gets, there is just no reason to take it out on mother nature! So maybe she should just stick to the path, that way no one thinks she is an enemy of the beautiful wildlife of our amazing globe.

Please put your tray away and return your seat to an upright position. Along with that, will the person that has left a mess in the aisles please stop being a jerk and clean up after yourself. There isn’t a lot of room, and on a long flight, most flyers will definitely eat a few meals or snacks. But the crew comes around frequently to collect trash, so don’t be a pain in the butt and just wait until then. That way, there won’t be a safety hazard, and you won’t look like a total jerk.

Everyone wants their own space, but when you are taking public transit, that space belongs to everyone. So make some room! Not only are these girls taking up seats that could be used by those left standing, but they have their feet up on the cushions. This is just bad manners all around. Someone should say something and let them know this is unacceptable.

No one wants your feet in their face as they are trying to enjoy their hot dog and a good game of baseball. This woman looks very comfortable, but what about the poor girl that can’t look left without a toe to the eye. This is just inconsiderate and a little gross. Fingers crossed this older lady has good hygiene and this doesn’t get even grosser. So keep your hands and feet in your seating area, and all will be okay.
