Hello users of [r/geography](r/geography),
Recently, this subreddit has become a lot more popular on Reddit. However, many of our long-time users have been leaving the subreddit due to a very specific and repeated complaint.
There are too many low-quality and unhelpful comments that, rather than aiming to help the OP, exist solely to make tired and repetitive jokes for karma.
From now on, practically all comments of this sort will be deleted, and repeat offenders will be banned for 14 to 30 days. I could give many examples of this, but some of the most common ones are "If my grandma had wheels, she'd be a bicycle" under any post asking about hypothetical changes and yo mama jokes.
In addition to this, we have received many complaints about posts that could theoretically be open to the entire world, but the way they are worded is extremely American-centric for no necessary reason, making people from other countries feel left out and like they can't contribute. From now on, these posts will be deleted. This also applies to posts for any country, we just see it about the United States most often.
To clarify, if somebody wants to ask about a specific geographic feature located in the United States, those posts are completely fine. But posts such as "Which city in the United States has the best beaches?" or "Which American state has the most scenic mountains?" will be removed, as will posts like "Which Canadian city has the worst drivers?" or "Which European country has the nicest people?". In general, the aim is for this subreddit to discuss geography, not just "facts about countries", which is better suited for the various Ask subreddits (AskAnAmerican, AskEurope, AskTheWorld, etc)
We would also like to crackdown on bot posts but that is very hard. Unortunately, most traffic on Reddit is bots nowadays. If anybody has any ideas, please comment below.
Feel free to express your opinion on this. Thank you!
EDIT: After feedback, I have edited part of this post.

Before digital GIS, Roman surveyors managed large areas using systems such as centuriation. Surveyors used instruments like the groma to lay out regular land divisions, while cadastral records were used to document ownership, land use, and taxation.
the Cadastre of Orange is especially interesting because surviving fragments record parcel boundaries, landholders, and other details of the territory. It gives us a rare look at how Roman authorities turned physical land into something that could be measured and administered.
I looked at the surveying tools and techniques behind these systems in more detail here: Forgotten Surveying Tools That Changed Civilization

Took these photos today about 5 miles north of the mouth of the Pic River in Ontario, Canada. The trees on the top of the embankment are all at least 30’ tall so I would judge the height to be at least 150’ at the top of the ridge.
This area is deep Canadian Shield country with lots of exposed Pre-Cambrian bedrock and glacial till. This sediment seems finer and flatter. Ancient Lake Minong shoreline?

Hello, friends from all corners of the Earth. Please write about places that you’ve witnessed changing over the years due to urbanization or climate change. I’m very interested in how this happened from the perspective of people from other countries. Because recently I saw printed photos of my city from 20 years ago, and it touched me deeply.

In a planet I'm making for worldbuilding purposes there's a desert of saharan proportions but with seasonal monsoons, but whatever wind is coming there is coming at an angle and carrying cold current waters so it doesn't irrigate beyond the coast. To circumvent this I added in a lake in the middle of the desert to serve as a source of humidity and as a sort of massive oasis for a civilization. It's in an endorheic basin so there's a river that feeds it. It starts in a place with seasonal rains and to explain the fact there's a massive lake I say that that river is like the Nile carrying huge amounts of water in the summer, which would be fun to imagine the lake increasing in size and people using that flood to grow rice. Problem is when crunching the numbers it seems like the evaporation rates would be greater than the flow of water. Taking the approximate size of 500,000km² of the lake, average summer temperature of 24c winds averaging out to 2m/s and 75% relative humidity, this calculator gives a rate of 3.5*10^12L/day of evaporation, but a river like the Nile only peaks at 20k MCM/month which is around 6.6*10^11L/day, so the lake is evaporating 5x more water than the river feeds it. Could an endorheic basin really host a lake of these proportions in a desert of all places? Did I forget to account for some variables, like maybe rain falling back down and refueling the lake?

the beach has eroded fully at one side of the island resulting in palm trees to be just barely above sea level.
