By studying lunar craters, scientists have discovered that the asteroid impacts became more frequent about 290 million years ago. So was just a matter of time for dinosaurs to becoming extinct.Continue reading Dinosaurs were already doomed as the frequency of Asteroid Impacts increased 290 million years ago
Our planet is getting warmer, with an increasing pace. This month, there were three bad, very bad news about global warming. According to a study published in Proceedings of the National Academy of Sciences, Antarctica is losing six times more ice mass annually now than 40 years ago. Another study, published in the scientific journal Advances in Atmospheric Sciences concluded that 2018 was the hottest year ever recorded for the Earth’s oceans. And, according to
The world has been urbanizing rapidly in recent decades. In 1950, only 30 percent of the world’s population lived in urban areas, a proportion that grew to 55 percent by 2018. The global urbanization rate masks important differences in urbanization levels across geographic regions.
Northern America is the most urbanized region, with 82 percent of its population residing in urban areas, whereas Asia is approximately 50 percent urban, and Africa remains mostly rural with 43 percent of its population living in urban areas in 2018 (United Nations, 2018).Continue reading The urbanization of the world
We only see one side of the moon, because it is tidally locked to the planet Earth (tidal locking the situation when an object’s orbital period matches its rotational period). What if the Earth was tidally locked to the Sun?Continue reading What if the Earth was tidally locked to the Sun?
What if the Earth’s history (our planet’s age is approximately 4.54 billion years), compressed into just one year, let’s say the year of 2018? @YearOnEarth just did that. At midnight on the 31st of December 2017, Chris Jennings started a little project for the incoming year: tweeting the entirety of the geological history of the Earth, compressed into the year of 2018.
The result is an amazing timeline of the Earth’s history.Continue reading What If Earth’s History Compressed Into The Year of 2018
NASA Goddard Planetary Scientist James O’ Donoghue created a nice animation showing the sidereal days and axial tilts of the solar system planets.Continue reading The sidereal days and axial tilts of the Planets
Fresh water is the most important resource for human life on earth. People can survive far longer without food than without water, and virtually all of our food sources require fresh water to grow or create.
Global climate change and the exponential increase in population has led to water scarcity and recent headline-grabbing water shortages in major urban centers like Capetown and Sao Paulo.
As water scarcity or cleanliness continue to present major issues to humanity’s survival, communities across the globe are turning to technology to help access more fresh water–or create it using seemingly ‘magic’ techniques.Continue reading Freshwater Is Disappearing. Can Technology Save Us?
Dr. Adam Nieman created this image in 2003, illustrating the volume of the planet Earth’s oceans and atmosphere (if the air were all at sea-level density) by rendering them as spheres sitting next to the Earth instead of spreading out over its surface.Continue reading All the Earth’s water and air

Explore with us some of its unforgettable features with this list of five geography facts that will blow your mind.Continue reading 5 Geography Facts that Will Blow Your Mind
We, humans, changing the Earth – mostly (almost always) in a bad way. Just over the last 25 years, we have destroyed 10% of the Earth’s wilderness. Now, a new world map created by the University of Cincinnati geography professor Tomasz Stepinski shows how the Earth’s surface has dramatically changed between 1992 and 2015.Continue reading New Maps Show How We Changed the Earth’s Surface Over the last 25 Years
