As today is the official day for people to panic (Panic Day) I thought I'd find something for you all to really panic about! Here's a great one from Listverse<-- so hit link for 10 different types of Mass Extinction!Here's something to alleviate the current trend fears: at this moment, the earth is in the middle of an ice age which began around 2.58 million years ago. We are in an interglacial period which started between 10,000 and 15,000 years ago and may last for a further 50,000 years before global glaciation begins again. (Thanks to NASA!)
The "humbug" in the picture is a rather beautiful Antarctic iceberg spotted by Oyvind Tangen. Its wonderful stripes are formed by a glacier passing over layers of different materials - sea-water rich in algae creates green stripes, fissures in the iceberg hat fills with meltwater turn bright blue. Brown and black layers are dust and soil picked up when it slides down the land collecting dust, soil and ash.
