If All the World’s Glaciers Were to Melt, Florida Would Disappear

Published

on

Did you know that the sea level is rising in Florida, and that it’s costing over $4 billion? In the present day, the sea level surrounding the Sunshine State is up to eight inches higher than it was back in 1950. With more than 120,000 properties at risk in Florida from the frequent tidal flooding, the state is taking action. Florida is currently planning over $4 billion in sea level rise solutions, including that of seawalls, stormwater improvements, protecting sewage systems and raising roads.

[OC] The Lost State of Florida: Worst Case Scenario for Rising Sea Level from r/dataisbeautiful


Created by Jonathan Callura in 2021, this visual uses data from the USGS National Geospatial Program. According to the visual, the global sea level would rise by approximately 70 meters (230 feet) if all of the glaciers on earth were to melt.

According to SeaLevelRise.org, Florida’s sea level has increased over the last decade, and has raised as much as one inch every three years. Because of this, experts are predicting that over the next fifteen years, the sea level in Florida will have risen by another half a foot.

Since 2000, tidal flooding in Florida has increased by approximately 352%, despite the sea level having only risen by an estimated three inches during that time. This is because high tides can lead to flooding, even on the sunniest of days, if the oceans have risen high enough.

“In 30 years Florida will see many more days of flooding, stronger storms, more extreme weather, and stagnant or declining coastal property values.” — Jim Cason, Former Mayor of the City of Coral Gables

The 20 Largest Cities in the World from 2800 BC to 2100 AD

Published

on

Let’s take a incredible journey through history to see the world’s largest cities over time with this animated visualization. This video, created by CityGlobeTour on YouTube, reveals the 20 largest cities in the world at any given moment throughout history from 2800 BC to 2100 AD. Hit play to live through the rise and fall of nearly every civilization of human history.

Play by play:

Starting in the year 2800 BC, the largest city by population was Uruk, Iraq. At a population of 80,000 people, Uruk had double the number of the next largest city which was also located in Iraq, the city of Larak; which had a population of 40,000. Out of the 14 cities listed in the year 2800, ten are located in Iraq, three are in Syria and one is in Iran. By 2500 BC, Uruk’s population is still the largest however it has shrunk to just over 46,000 people and the city of Mari in Syria has moved up the list with a population of 43,853. Just a few hundred years before in 2730 BC, the city of Mari had a population of just 13,797. Jumping even further to 2000 BC the moving chart shows that Egypt and Pakistan are added to the mix and in 1930 BC the city of Memphis Egypt jumps into the number one spot with a population of 56,517. It isn’t until the year 1660 BC that China pops up on the list and very quickly jumps to the top four largest with the city of Erlitou, population of 39,813. In 1500 BC Greece has had a boom in the city of Knossos, population of 42,857. It isn’t until the year 1300 BC that a city has a population of more than 100 thousand. Thebes (Luxor) in Egypt tops the list with 100,726 people in the city. As you can see, this animated bar graph is super interesting, and spoiler alert: it gets even more interesting! As you continue your way through the animation, you’ll notice the US first appear in the year 1834 with New York City’s population of 255,797!

How Dramatically the Smartphone Market Has Changed Since 2010

Published

on

I remember my first cell phone. It was an orange Nokia, the thing felt like a brick, and I’m pretty sure it was indestructible. I wish that I still had it stowed away in the attic because I would love to get in another game of Snake! Back in the early 2000’s, not many people sent texts; at least not like they do today. T9 texting required you to form words with the 9 buttons you had on the phone. It took forever, so a quick phone call was usually a much easier way to communicate.

Today, our phones are more like minicomputers, soaking up our time and demanding our attention with every notification. This animated pie chart visualization which was originally shared on Reddit’s /r/DataIsBeautiful subreddit by creator /u/jcceagle shows just how much the phone market has changed since 2010.

You’ll see that Nokia dominated the market from April 2010 right up until January of 2013 when they were overtaken by both Samsung and Apple. They quickly became almost non-existent making up only 5.18% of the market in July of 2016. In 2016, Samsung was the dominate phone brand with 32.18% of the market. Moving to April of 2019, you can see Samsung is still on top with the most share of the cell phone market, but with Apple is right behind them. Chinese phone manufacture Huawei starts to make a larger appearance with around 10% of the market by December of 2019. By the end of March 2021, Samsung is hanging on to its lead by only a thread. Only a .94% margin separates Samsung and Apple. Their battle for smartphone dominance has been ongoing for years, with no end in sight. Xiaomi and Huawei (both Chinese companies) come in 3rd and 4th in market share. In 2021, Nokia, which once dominated the industry, represents just .64% of the cell phone market.

The Subreddits With the Most Comments, Every Single Day from 2018-2021

Published

on

At any specific date in time, trending Reddit subs can provide a snapshot to what users are thinking, searching and talking about. Sports, politics, gaming, current events and more can significantly boost comment numbers in specific Subreddits. This animated bar graph visualization from u/Balloon_Project, which was shared in the Data is Beautiful Subreddit, shows the most commented subreddits from 2018 to Jan 27th 2021. Check it out here:

Most commented subreddits, 2018-21 [OC] from r/dataisbeautiful

Using information from SubredditStats.com, Balloon_Project was able to write a custom script in a program called Processing to input all the data. In the 2 and a half minute video, you can watch subreddits move and up and down the ladder with an accompanying “Todays’ News” headline for that specific day. It is fun to watch the different spikes that show up around different events. For example, the subreddit r/marvelstudios shows up high on the graph when Endgame gets released.

Sports subreddits like r/nba and r/nfl peak during key events for their respective leagues, and r/politics jumps to the top for major events surrounding the election, impeachment, protests, and riots. Meme pages and general subs like r/pics, r/teeenagers, and r/funny tend to bounce around in the top ten spots randomly as they are consistently popular subreddits. The general info sub r/askreddit where users can ask any question that comes to mind stayed in the top position for years getting 80 to 120k comments per day.

Here are some notable events and how Reddit reacted:

  • At the start of the COVID-19 pandemic in March, you can watch r/coronavirus surge to around 60 thousand comments per day.
  • Around the election in November of 2020, the r/politics sub surges past 200k comments per day, the highest number seen in the video to that point.
  • Rounding out the last days of the graph you can watch the Wall Street Bets sub (r/wallstreetbets) soar to incredible new levels on the graph, getting close to 400 thousand comments per day during the whole GameStop stock debacle.

What a neat way to visualize this data!
