Most of these are islands because those are the ones I know of, but I tried to include a few landlocked ones as well

That "world's most populous city poll" started me wondering how many countries* those cities have a bigger population than...

Tokyo's population (37,435,191) is bigger than that of 170 countries, including Saudi Arabia's (36,952,585) and Ukraine's (36,758,716). In comparison, Canada has a population of 38,784,727.

Delhi's population (29,399,141) is bigger than that of 159 countries, including Cote D'Ivoire's (28,880,603) and Venezuela's (28,844,390)

Shanghai's population (26,317,104) is bigger than that of 154 countries, including North Korea's (26,161,743) and Taiwan's (23,923,572). In comparison, Australia has a population of 26,441,853.

São Paulo's and Mexico City's populations (21,846,507 and 21,671,908) are bigger than those of 148 countries, including Malawi (20,937,323) and Zambia (20,575,606)

And the populations of Cairo (20,484,965), Mumbai (20,185,064), Beijing (20,035,455), and Dhaka (20,283,552) are bigger than those of 146 countries, including Romania (19,889,414) and Chile (19,629,887)

tossing this out there, does anyone have a recommendation for a World Geography book for high school? Kiddo's class isn't getting books, just relying on note taking.

When you know the Köppen Climate Classification system well enough to know that y'all are finding matching climates here. Similar weather produces similar terrain and plant life. Going down each pair you've got:

-subarctic montane (Dfc) -humid subtropical (Cfa) -oceanic climate (Cfb) -cold semiarid (BSk) -tropical monsoon (Am or Aw, not sure where in "India" that is) -continental warm summer (Dfa) -Mediterranean (Csa) -subarctic oceanic (Cfc) -this isn't climate but the borealises are the same phenomenon happening at two sides of the globe and actually mirror each other -tropical rainforest (Af) -hot arid and semiarid (BWh, BSh) -France and Korea are actually the only two exceptions because East Asia has a monsoon-influenced climate and doesn't get hit by the gulf stream, so they're Cfb and Dwb respectively. I also think they look the least alike of these photos.

Kinda in love with the idea that different places on other sides of the world can look so similar. Something something universal human experiences

Hey All,

I've been away for some time, as we've been working really hard on something quite exciting:

let me present to you the world's first ever global ocean drainage basin map that shows all permanent and temporary water flows on the planet.

This is quite big news, as far as I know this has never been done before. There are hundreds of hours of work in it (with the data + manual work as well) and it's quite a relief that they are all finished now.

But what is an ocean drainage basin map, I hear most of you asking? A couple of years ago I tried to find a map that shows which ocean does each of the world's rivers end up in. I was a bit surprised to see there is no map like that, so I just decided I'll make it myself - as usual :) Well, after realizing all the technical difficulties, I wasn't so surprised any more that it didn't exist. So yeah, it was quite a challenge but I am very happy with the result.

In addition to the global map I've created a set of 43 maps for different countries, states and continents, four versions for each: maps with white and black background, and a version for both with coloured oceans (aka polygons). Here's the global map with polygons:

I know from experience that maps can be great conversation starters, and I aim to make maps that are visually striking and can effectively deliver a message. With these ocean drainage basin maps the most important part was to make them easily understandable, so after you have seen one, the others all become effortless to interpret as well. Let me know how I did, I really appreciate any and all kinds of feedback.

Here are a few more from the set, I hope you too learn something new from them. I certainly did, and I am a geographer.

The greatest surprise with Europe is that its biggest river is all grey, as the Volga flows into the Caspian sea, therefore its basin counts as endorheic.

An endorheic basin is one which never reaches the ocean, mostly because it dries out in desert areas or ends up in lakes with no outflow. The biggest endorheic basin is the Caspian’s, but the area of the Great Basin in the US is also a good example of endorheic basins.

I love how the green of the Atlantic Ocean tangles together in the middle.

No, the dividing line is not at Cape Town, unfortunately.

I know these two colours weren’t the best choice for colourblind people and I sincerely apologize for that. I’ve been planning to make colourblind-friendly versions of my maps for ages now – still not sure when I get there, but I want you to know that it’s just moved up on my todo-list. A lot further up.

Minnesota is quite crazy with all that blue, right? Some other US states that are equally mind-blowing: North Dakota, New Mexico, Colorado, Wyoming. You can check them all out here.

Yes, most of the Peruvian waters drain into the Atlantic Ocean. Here are the maps of Peru, if you want to take a closer look.

Asia is amazingly colourful with lots of endorheic basins in the middle areas: deserts, the Himalayas and the Caspian sea are to blame. Also note how the Indonesian islands of Java and Sumatra are divided.

I mentioned earlier that I also made white versions of all maps. Here’s Australia with its vast deserts. If you're wondering about the weird lines in the middle: that’s the Simpson desert with its famous parallel sand dunes.

North America with white background and colourful oceans looks pretty neat, I think.

Finally, I made the drainage basin maps of the individual oceans: The Atlantic, the Arctic, the Indian and the Pacific. The Arctic is my favourite one.

I really hope you like my new maps, and that they will become as popular as my river basin maps. Those have already helped dozens of environmental NGOs to illustrate their important messages all around the world. It would be nice if these maps too could find their purpose.

Doing another one of these. Go here to name the countries of the world in fifteen minutes

Dividing it like this bc I figure us americans tend to be notoriously inept at world geography

hey uh so I haven't seen anyone talking about this here yet, but

the amazon river, like the biggest river in the fucking world, in the middle of the amazon fucking rainforest, is currently going through its worst drought since the records began 121 years ago

picture from Folha PE

there's a lot going on but I haven't seen much international buzz around this like there was when the forest was on fire (maybe because it's harder to shift the narrative to blame brazil exclusively as if the rest of the world didn't have fault in this) so I wanted to bring this to tumblr's attention

I don't know too many details as I live in the other side of the country and we are suffering from the exact opposite (at least three cyclones this year, honestly have stopped counting - it's unusual for us to get hit by even one - floods, landslides, we have a death toll, people are losing everything to the water), but like, I as a brazilian have literally never seen pictures of the river like this before. every single city in the amazonas state is in a state of emergency as of november 1st.

pictures by Adriano Liziero (ig: geopanoramas)

we are used to seeing images of rio negro and solimões, the two main amazon river affluents, in all their grandiose and beauty and seeing these pictures is really fucking chilling. some of our news outlets are saying the solimões has turned to a sand desert... can you imagine this watery sight turning into a desert in the span of a year?

while down south we are seeing amounts of rain and hailstorms the likes of which our infrastructure is simply not built to deal with, up north people who have built everything around the river are at a loss of what to do.

the houses there that are built to float are just on the ground, people who depend on fishing for a living have to walk kilometers to find any fish that are still alive at all, the biodiversity there is at risk, and on an economic level it's hard to grasp how people from the northern states are getting by at all - the main means of transport for ANYTHING in that region is via the river water. this will impact the region for months to come. it doesnt make a lot of sense to build a lot of roads bc it's just better to use the waterway system, everything is built around or floats on the river after all. and like, the water level is so incomprehensibly low the boats are just STUCK. people are having a hard time getting from one place to another - keep in mind the widest parts of the river are over 10 km apart!!

this shit is really serious and i am trying not to think about it because we have a different kind of problem to worry about down south but it's really terrifying when I stop to think about it. you already know the climate crisis is real and the effects are beyond preventable now (we're past global warming, get used to calling it "global boiling"). we'll be switching strategies to damage control from now on and like, this is what it's come to.

I don't like to be alarmist but it's hard not to be alarmed. I'm sorry that I can't end this post with very clear intructions on how people overseas can help, there really isn't much to do except hope the water level rises soon, maybe pray if you believe in something. in that regard we just have to keep pressing for change at a global level; local conditions only would not, COULD NOT be causing this - the amazon river is a CONTINENTAL body of water, it spans across multiple countries. so my advice is spread the word, let your representatives know that you're worried and you want change towards sustainability, degrowth and reduced carbon emissions, support your local NGOs, maybe join a cause, I don't know? I recommend reading on ecological and feminist economics though

however, I know you can help the affected riverine families by donating to organizations dedicated to helping the region. keep in mind a single US dollar, pound or euro is worth over 5x more in our currency so anything you donate at all will certainly help those affected.

FAS - Sustainable Amazon Fundation

Idesam - Sustainable Developent and Preservation Institute of Amazonas

Greenpeace Brasil - I know Greenpeace isn't the best but they're one of the few options I can think of that have a bridge to the international world and they are helping directly

There are a lot of other smaller/local NGOs but I'm not sure how you could donate to them from overseas, I'll leave some of them here anyway:

Projeto Gari

Caritás Brasileira

If you know any other organizations please link them, I'll be sure to reblog though my reach isn't a lot

thank you so much for reading this to the end, don't feel obligated to share but please do if you can! even if you just read up to here it means a lot to me that someone out there knows

also as an afterthought, I wanted to expand on why I think this hasn't made big news yet: because unlike the case of the 2020 forest fires, other countries have to hold themselves accountable when looking at this situation. while in 2020 it was easier to pretend the fires were all our fault and people were talking about taking the amazon away from us like they wouldn't do much worse. global superpowers have no more forests to speak of so I guess they've been eyeing what latin america still has. so like this bit of the post is just to say if you're thinking of saying anything of the sort, maybe think of what your own country has done to contribute to this instead of blaming brazil exclusively and saying the amazon should be protected by force or whatever

Okay so the other day I was taken aback by how many countries* the world's most populous cities were bigger than so I started researching some more and GET THIS!

There are 32 cities with a population greater than 10 million - if you live in one of these, your city has a bigger population than 114 countries.

There are 83 cities with a population greater than 5 million - if you live in one of these, your city has a bigger population than 84 countries.

There are 255 cities with a population greater than 2 million - if you live in one of these, your city has a bigger population than 59 countries.

There are 574 cities with a population greater than 1 million - if you live in one of these, your city has a bigger population than 49 countries.

Idk to me that's just fascinating!
