The Earth once had a frozen shell of ice encasing oceans, land, from pole to pole. The mystery: what process could suffice To kiss Snow White, rouse cryogenic soul. One theory says volcanic CO2 Would slowly warm the Earth until the thaw As ice breaks up, the air and water brew: Carbonic acid forms: paleo-spa. The isotopes of boron measure bases. Post-glacial carbonates record the change As

With 2014 officially named the hottest year on record, there is evidence of the effects of rising global temperatures across the globe. The solitary, shimmering iceberg in today’s Imaggeo on Mondays photograph is a reminder that one of the best places to look for evidence of change is in glaciers. Daniela Domeisen tells the story of this lonely frozen block of ancient ice. The picture shows an iceberg on Tasman glacier lake in the Southern Alps of New Zealand, in the centre of Aoraki / Mount [...]

The EGU General Assembly brings together geoscientists from all over the world to one meeting that covers all disciplines of the Earth, planetary and space sciences. Following from last year’s success, the EGU General Assembly will have a theme: A Voyage Through Scales. The theme is an invitation to contemplate Earth’s extraordinary variability extending from milliseconds to its age and from microns to the size of the planet. The theme does not constrain the topics to be presented at the [...]

Many artists draw inspiration from nature and it’s not surprising when faced with landscapes which are as beautiful as the one featured in this week’s Imaggeo on Mondays post. Josep Miquel Ubalde Bauló writes about the origin of the colourful mud pots and bobby-socks trees! This picture corresponds to The Artist Paint Pots, found in in Yellowstone, the first National Park of the world. Yellowstone is one of the most geologically dynamic areas on Earth.

The Suomi satellite has the ability to get images of the Earth at night, and this week it grabbed one of the prettiest shots yet, under the light of a full Moon. With clear skies and snow on the ground, you can see the snow and if you look closely you can see some high clouds on top of the lights across portions of Iowa and Minnesota. You can get a much

Measuring the temperature of solar winds 

AGU Meetings [2015-01-05 16:16:13]  recommend  recommend this post  (26 visits) info

The sun spews forth super-heated, charged particles, collectively called plasma, that fly out into the vacuum of space at speeds of 200 to 400 miles per second (300 to 700 kilometers per second). These waves of plasma make up the solar winds that spread across our solar system. Traveling across freezing space should suck all the heat from the plasma by the time it nears Earth, but the solar waves detected near our planet are still hot. Scientists think something is happening within the [...]

The Larsen Ice Shelf is a huge piece of ice that sits on the other side of the Antarctic Peninsula from Rothera Station. It is divided into sections, which are named, from north to south (left to right, in the map), the Larsen A, B, and C. Back in 2002, a large piece of the Larsen B broke off into the ocean. The piece that broke off was 1,250 square miles, about the size of Rhode Island! It broke apart and fell into the ocean over a course of about a month. (You can see the satellite images of [...]
