Mount Etna, Europe’s most active volcano (also one of the most active volcanoes in the world) is sliding into the Ionian Sea at rates of centimeters per year. If part of it falls into the sea, it could create horrible mega-tsunamis that would devastate the eastern Mediterranean shores.Continue reading Mount Etna is sliding into the sea
As a result of the global warming, the seas warm and ice melts. Naturally, Earth’s oceans have risen steadily – or at least, it was thought so. According to a new study based on 25 years of NASA and European satellite data, rather than increasing steadily, global sea level rise has been accelerating in recent decades. If this trend continues, by the year 2100, sea level rise will be around 65 cm (25.6 in), twice as big as previously thought. This is more than enough to cause significant problems for coastal cities.
Satellite altimetry Notes 1 has shown that since 1993, global mean sea level has been rising at a rate of ∼3 ± 0.4 millimeters per year. Researchers show that this rate is accelerating at 0.084 ± 0.025 mm/y2, which agrees well with climate model projections. This acceleration is driven mainly by increased melting in Greenland and Antarctica because of global warming. If sea level continues to change at this rate and acceleration, sea-level rise by 2100 (∼65 cm ± 12 cm, compared with 2005) will be more than double the amount if the rate was constant at 3 mm/y, researchers conclude.Continue reading Global Sea Level Rise Accelerating, New Study Finds
NASA astronaut Randy “Komrade” Bresnik, the commander of the Expedition 53 (the 53rd expedition to the International Space Station) has published a beautiful video on his twitter account titled “Through the eyes of a spaceman: One World Many Views”. In the video, Bresnik shared photos of places he’d visited on Earth alongside photos of the same locations he snapped from space. He also wrote: “You don’t have to be in outer space to experience the beauty of our home planet. Capture the beauty of a moment, or the excitement of an instant, and share it with others.”
There are a total of 1073 UNESCO World Heritage Sites in the world (as of January 2018: 832 Cultural, 206 Natural and 35 Mixed). Here are the top 20 countries having the most number of UNESCO World Heritage sites.
What is a UNESCO World Heritage Site? According to the Wikipedia, “A World Heritage Site is a place (such as a building, city, complex, desert, forest, island, lake, monument, or mountain) that is listed by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as being of special cultural or physical significance.“Continue reading Top 20 Countries having most number of UNESCO World Heritage Sites (2018 Update)

There are a lot of natural and human-made wonders in the world. But everything has an end, and sooner or later, they’ll be gone. Unfortunately, some of them will be vanished sooner, even in a few decades. Here are eight of them, just in case you may want to see before they are gone.
Since the Neolithic revolution,
The “Seven Wonders of the World“, describes seven great constructions known in the Hellenistic period – that’s why they are also known as the “Seven Wonders of the Ancient World”. In fact, in the Hellenistic era, each famous traveler had his own version of the list, but the best known and earliest surviving was from a poem by Greek-speaking epigrammist Antipater of Sidon, which he described in a poem composed about 140 BC:
“I have set eyes on the wall of lofty Babylon on which is a road for chariots, and the statue of Zeus by the Alpheus, and the hanging gardens, and the Colossus of the Sun, and the huge labor of the high pyramids, and the vast tomb of Mausolus; but when I saw the house of Artemis that mounted to the clouds, those other marvels lost their brilliancy, and I said, ‘Lo, apart from Olympus, the Sun never looked on aught so grand.'”
But, in fact, all “seven wonders of the world“ existed at the same time for a period of less than 60 years. And now, only the Great Pyramid of Giza still in existence. All the others somehow gone.
If Antipater of Sidon was living in the more recent times, say
