Animation Shows Earth’s Temperature Trends from 0 to 2019 AD

Published

on

Today’s animation comes to us from Reddit user /u/bgregory98 and visualizes global temperature trends from 0 to 2019 AD, the results are eye-opening:

Across the 2,000-year timeline, average global temperatures remain largely steady for the first 1,000 years and drop slightly for the next 500-750 years; what’s truly interesting about this animation is what happens in the final 200+ years. As the timeline approaches the industrial age, temperatures begin to rise and then skyrocket through to the modern day… the evidence is almost unsettling; human activity is undeniably affecting Earth’s temperatures.

Global warming and climate change have been hot topics for years. Even so, some people still don’t believe it’s real. However, scientists have studied climate models going back 50 years that have accurately predicted warming temperatures across the globe. These global temperatures have consistently risen around 0.9 degrees Celsius since 1970. What these models have also confirmed is that human activity is the cause. Climate change is caused from excess CO2 in the atmosphere. When people burn fossil fuel it creates carbon dioxide. This CO2 releases heat which then gets trapped in the earths upper atmosphere for 100 years, heating up the surface and leading to climate destruction. When scientists go to study climate change one thing they look at are Oxygen isotopes from ocean sediment. This is because they are tied to the earths ice caps. When water evaporates from the ocean’s surface, light isotopes of oxygen evaporate quicker because it takes less energy to break the chemical bonds. If these light isotopes then get carried to polar ice caps and trapped in the ice the ratio of these isotopes in the ocean goes down. What we are seeing now is the exact opposite. As the ice caps melt more oxygen isotopes are deposited into the ocean and the sea level rises. These ratios are recorded in shells of marine microorganisms and allow scientists to record how much the ice caps have grown or shrank around the globe. 


Economists and scientists alike believe that taxing carbon is one way to strengthen the global response towards climate change. A carbon tax is a fee that would be imposed on the use of coal, oil and gas. The goal would be to motivate people to move to cleaner energy sources by saving them money and also making them more energy efficient. Judging by the information in this automated graphic, the worlds temperature is going to continue to grow at an exponential rate because of the human race. What we do today will determine if this leads to the destruction of earth in hundreds of years or if we can slowly begin to repair the damage done. If everyone did their part even just small changes can make a big difference!

The Oldest Logos That Are Still in Use Today

Published

on

Logos are powerful – they convey the entire essence and history of a brand within a single image. It is truly incredible to imagine how a designer can shape the entire legacy of a brand with their creations! While some company logos undergo immense transformations with the changing times, some stay true to their roots, maintaining imagery that resonates for generations. At Chartistry, we love learning about the history of design and marketing, so we were thrilled to discover this chart by ImageRelay. It explores the oldest logos that still exist today, dating all the way back to 1366.

It is fascinating to see how many of the logos underwent style changes but still maintained distinctive core elements – I love a brand that stays true to its story! So the oldest logo that still exists today belongs to Stella Artois, a Belgium beer company. It began as just the horn, but now sports an elegant banner. What is the horn on Stella Artois? The horn represents the Den Hoorn brewery in Leuven, Belgium, where Stella Artois traces its origins. In 1366, Stella Artois was a special brew given by the brewery as a holiday gift to the people of Leuven. The name “Stella”, which means “star” in Latin, pays homage to that special occasion. The name “Artois” honors the De Hoorn Bew Master Sebastian Artois. Learning about the history of logos can be so fun, especially when they have protected the very elements that have defined the brand from the beginning.

Chart Shows Inflation is Outpacing Teacher Salaries (1990-2022)

Published

on

Schools in the US are facing a lot of problems and one of the biggest is how they treat their teachers. If you have ever been on the r/Teachers subreddit then you know exactly what I am talking about. The subreddit is becoming more and more filled with complaints about teaching. The complaints range from disinterested kids and unruly parents to administrators that seem to care about state-sponsored standardized test scores more than anything else.  You would think that with all the teaching shortages and the upheaval created by the COVID-19 pandemic, teachers would be seeing an increase in salaries, but this graph shows that new teachers today are actually earning 11% less than their peers from 30 years ago.

With inflation in mind a starting teachers salary today should be around $46,762 but today they are only making around $41,780 on average. Looking at the graph you can see that since 1990 the salary with inflation and the actual starting salary have been pretty close to one another until you get to 2022 where you see such a large difference. If things don’t change soon, students will continue to suffer. Students are already considered to be behind due to disruptions from the pandemic. Good teachers are needed now more than ever, so let’s pay them what they deserve.

How the Price of a Big Mac Has Changed Around the World (2000-2022)

Published

on

The iconic Big Mac is a two-beef patty, three bun delicacy topped with iceberg lettuce, American cheese, pickles, chopped onions and the super secret Mac Sauce. In 1968, it was so popular with its limited release in Pennsylvania that it was rolled out to every McDonald’s restaurant across the United States. That popularity never waned and there is now an entire economic phenomenon known as ‘burgernomics’ modeled from the Big Mac. Economists will use the price of the big mac as a way to gauge inflation rates and economics across globe. Today the Big Mac is up 40% from 2010. We can see in this video visualization by /u/jcceagle that follows the price of a Big Mac over the last 20 years, just how different cost can be across the globe and over time.
In the year 2000 Norway had the most expensive Big Mac for $4.09, while in the Philippines it cost $1.17. Eight years later, Norway still tops the charts with the most expensive Big Mac but instead of just over four dollars, it increased to $7.88. At that time in the US a Big Mac cost $3.57 while the cheapest was found in Malaysia for $1.70 and the Philippines increased to $1.96. In July 2017 the most expensive Big Mac was down across the board from 2008 to $6.74 in Switzerland. That same year a Big Mac in the US would have cost you $5.30 and $1.70 in the Ukraine. The video also shows an index of currency valued relative to the US dollar where you can see the values changes across the different currency around the world.
