What If Earth’s History Compressed Into One Year

What if the Earth’s history (our planet’s age is approximately 4.54 billion years), compressed into just one year? @YearOnEarth just did that. At midnight on the 31st of December, Chris Jennings started a little project for the incoming year: tweeting the entirety of the geological history of the Earth, compressed into one year. The result …

We are Destroying the Earth’s Wilderness

We, humans, are destroying the Earth’s wilderness at an alarming pace. Scientists say we have destroyed 10% of Earth’s wildlife habitat in just 25 years. Since 1993, 3.3 million km2 of global wilderness areas, particularly in the Amazon basin (almost 30%) and central Africa (14%) were lost. This is almost twice the size of Alaska!

Earth can be a model for detecting vegetation on exoplanets

Back in December 1990, during its flyby of Earth, NASA’s Galileo spacecraft, which studied the planet Jupiter and its moons, as well as several other Solar System bodies, pointed its instruments towards Earth, at the urging of Carl Sagan. And, it has found evidence of life on our planet. This can be a key to detecting …

Rainforests of the World (Infographic)

Rainforests are the oldest living ecosystems and without a shadow of a doubt, the most vital habitats on Earth. They cover only 6% of the Earth’s surface but yet they contain more than half of the world’s plant and animal species. According to the current estimates, around 40% to 75% of all biotic species are indigenous (see notes …

Bananas have died out once before – don’t let it happen again

You probably take bananas for granted. In the United Kingdom, one in four pieces of fruit consumed is a banana and, on average, each Briton eats 10 kg of bananas per year; in the United States, that’s 12 kg, or up to 100 bananas. When I ask people, most seem to think bananas grow on …

Most species hold their geographic range if we limit global warming to 1.5°C, study says

If we limit global warming to 1.5°C rather than 2°C above the pre-industrial levels by the year 2100, the impacts of climate change would be much less dramatic, a new study says. According to the researchers, for vertebrates and plants, the number of species losing more than half their geographic range by 2100 will be …

Earth’s Biosphere from space, “The Green Marble”

NASA has published a video titled “Earth’s Biosphere: The Green Marble”, showing the monthly averages of land greenness (vegetation) and ocean chlorophyll. You can watch how the primary producers (plants and phytoplankton) transform the Earth’s landmasses and oceans over 12 months.

What did Ancient Earth Look Like

I stumbled upon an amazing web page showing what did ancient Earth look like. On the “Dinosaur Pictures and Facts” web page (dinosaurpictures.org), there’s also an interactive animation. On this page, you can either select the years (i.e. 600 million years ago) or jump to a particular event (i.e. first multicellular life) and see how ancient …

Iceland is growing new forests for the first time in 1,000 years

Iceland was extensively forested when it was first settled. When the Vikings first arrived in the 9th century, the Nordic island was covered in 25 to 40 percent forest, compared to 1% in the present day. In the late 12th century, Ari the Wise (Ari Thorgilsson, 1067-1148 AD), Iceland’s most prominent medieval chronicler, described it …

10 Recently Lost Natural Wonders

The Earth is always changing. “The only thing that is constant is change“, as Heraclitus (c. 535 – c. 475 BC) the pre-Socratic Greek philosopher once said. Unfortunately, things do not always happen the way we would have wanted. Here are 10 recently lost natural wonders that have been disappeared in recent centuries or even …
