The magnetic field of Earth is constantly changing. And, at the moment, even more rapidly than previously thought – up to 10 times, as British researchers have now figured out. This has significant implications not just for the old-school magnetic compass navigation but also for the proper functioning of telecommunications networks and GPS-and thus for […]
NASA has published visualizations of the amount of ice loss from the polar ice caps in a post titled “Visualizing the Quantities of Climate Change: Ice Sheet Loss in Greenland and Antarctica”.
This NASA visualization shows a rapid decline in Arctic Sea ice over the last 35 years, based on satellite observations. The situation is really bad: in the 1st week of January 1988, over 1.2 million sq. miles (3.1 million km2) were covered by sea ice 4 years of age or older, compared with just over […]
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 […]
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 […]
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 […]
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 […]
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. […]
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 […]
Climate Central channel has put the 116 years history of global warming into a just 34-second video. The result is terrifying.
