Our dynamic planet has an apparent paradox: the more ice melts from landlocked glaciers, the lower the sea level gets in nearby areas. How does this happen? Through the physics of isostatic rebound, when the surface of the planet acts as an elastic sheet dimpling and rebounding under changing loads.
Recent headlines are warning that the Earth will enter into a “mini ice age” in about 20 years because the sun is heading towards a period of very low output. Here’s why this scenario is extremely unlikely.
For any band, shifting musical direction is a huge moment. For some it definitely works—could you imagine The Beatles pumping out A Hard Day's Night clones for decades?–and for others, even iconic musicians, it can be an earsplitting disaster.
A 65-foot deep shaft being dug for Los Angeles's newest subway line is filled with buried treasure. The so-called Subway to the Sea is still nine miles from the beach, but excavation has already revealed some creatures from the ocean floor… the prehistoric ocean floor!
Since our planet was born, it's gone through periods of extreme cold known as ice ages—but you might not realise just how of the cold stuff came with them. Spoiler: a lot.
Bones recently excavated at a cave in Southwestern England show that some 14,700 years ago, people used human skulls as cups. The people of the Ice Age even had the decency to clean the skulls of any soft tissue and use stone tools to shape the skulls to be more cup-like. Resourceful, I guess. [PLoS One via Wired]
