On April 15, 1912, RMS Titanic, which was the largest ship afloat at the time she entered service, sank in the North Atlantic Ocean after colliding with an iceberg during her maiden voyage from Southampton to New York City.
It was one of the deadliest commercial marine disasters in modern history: of the estimated 2,224 passengers and crew aboard, more than 1,500 died.
Here is a real-time animation of the RMS Titanic’s sinking below, published by Titanic: Honor And Glory channel.

Around 55.5 million years ago, there was a time period with more than 5°C – 8 °C warmer global average temperature than today, which named “Paleocene-Eocene Thermal Maximum” (PETM). As a result, there were crocodiles and even crocodiles in the Arctic and the region was completely ice-free. Now, a new study suggests that if we keep burning fossil fuels at the current rate, the Earth will be again 8 degrees warmer within the next few hundred years. We’re going to face another PETM-like event soon.

In this episode of NASA Explorers (Season 1 Episode 7), the scientists go back in time – by going underground. In the Arctic, a frozen layer of soil – permafrost, the “permanently” frozen earth – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane – two harmful greenhouse gases which contribute to global warming.

An interesting map showing the locations of North Magnetic Pole since 1590. The North Magnetic Pole moves over time due to magnetic changes in the Earth’s core. Today, the Geographic North Pole (the point in the Northern Hemisphere where the Earth’s axis of rotation meets its surface, the northernmost point on the Earth) differs from the North Magnetic Pole by about 500 kilometers (311 miles).
If a magnetic compass needle is allowed to rotate about a horizontal axis, it would point straight down at the North magnetic pole.

A lazy buzz phrase – ‘Is this the new normal?’ – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it’s worse than that – we’re on the road to even more frequent, more extreme events than we saw this year.
We have known since the 1980s what’s in store for us. Action taken then to reduce emissions by 20 per cent by 2005 might have restricted the global temperature rise to less than 1.5 degrees Celsius. But nothing was done, and the welter of climate data mounting since then only confirms and refines the original predictions. So where are we now?

Last winter, unforgettable video footage online showed a starving polar bear, struggling in its Arctic hunting grounds. Because of global warming, the ice was thin and the food supply was scarce. The video generated a wellspring of sympathy for the plight of this poor creature, and invigorated calls for stronger efforts to combat climate change – and rightly so.
Such advocacy on behalf of wildlife usually focuses on species and the effects of human-caused climate change on their survival and wellbeing as the ecosystems on which they depend undergo drastic changes. Thus, we should act to save the polar bear – that is, the polar bear species – by doing what we can to preserve its natural ecosystem. I am fully behind this kind of advocacy. Anybody who cares about the future of our planet and its occupants should be.

Global warming is accelerating – that’s a fact. In April 2018, the level of carbon dioxide in Earth’s atmosphere hit the highest point for the last 800,000 years. NASA and NOAA analyses suggest that long-term global warming trend continued in 2017. This year (2018), on March 17, the Arctic sea ice cover peaked at only 5.59 million square miles (14,478,033.54 km2), the 2nd lowest max on record (and the lowest max on record was, guess it, in 2017). 25 years of NASA and European satellite data shows that rather than increasing steadily, global sea level rise has been accelerating in recent decades. Cooler-than-normal years start to become rarer and by the 1990s, they’ve almost disappeared completely. Climate Central channel has put the 116 years history of global warming (1900-2016) into a just 34-second video. The result is terrifying. The “Temperature Circle” shows every nation on the Earth is now in the red, which means now every year is warmer-than-normal.

An island or isle is any piece of sub-continental land that is surrounded by water. It is believed that there are over 100,000 islands in the world. It’s difficult to put a figure to the exact number as there are different kinds of them in various water bodies including oceans, seas, lakes, and rivers. There is even an island within a lake that is situated on an island located in a lake on an island. Only 322 of them are larger than 1000 km2 (386 sq mi). Here are the top 18 largest islands on Earth. Why 18? Because this is the number of islands that have a land area of greater than 100,000 square kilometers (38,610 square miles).

The sea ice cover blanketing the Arctic Ocean and nearby seas thickens and expands during the fall and winter each year. It reaches its maximum yearly extent in February or March. This year (2018), on March 17, the Arctic sea ice cover peaked at only 5.59 million square miles (14,478,033.54 km2), the 2nd lowest max on record. It is only about 23,200 square miles (60,000 square kilometers) larger than the record low maximum reached in last year, on March 7, 2017.
This continues a trend of shrinking sea ice, with the four lowest Arctic sea ice maximum extents on record in the last four years. In the video published by the NASA Goddard Channel, Climatologist, and NASA Aqua Project scientist Dr. Claire Parkinson explains how and why NASA studies Arctic sea ice. Dr. Parkinson has been studying sea ice from space for the past four decades.

How far away can you get from everybody else on Earth? A video, published by RealLifeLore channel on YouTube answers this very question. The answer is “actually quite far”, there are a lot of extremely remote places left in the world and some of them have actually yet to be reached by anybody in all of history. The world is an enormous place. Here are the most remote places on Earth.
