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

Want to communicate your research to a wider audience and try your hand at video production? Now’s your chance! Young scientists pre-registered for the EGU General Assembly are invited to take part in the EGU’s Communicate Your Science Video Competition! The aim is to produce a video up-to-three-minutes long to share your research with the general public. The winning entry will receive a free registration to the General Assembly in 2016. Your video can include scenes of you out in the field [...]

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 [...]
This is the third time in the 21st Century that the Earth has recorded it’s hottest year on record. More from NOAA Here: Global Temperatures A record warm December sealed the deal to make 2014 the warmest year across the world’s land and ocean surfaces since recordkeeping began in 1880. The average temperature for the year was0.69°C (1.24°F) above the 20th century average of 13.9°C (57.0°F), beating the previous record warmth of

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. A huge underlying magma body releases [...]
In January of 1870, Alfred Russel Wallace found himself on a collision-course with a group of creationists who fervently believed the earth is flat. The father of biogeography, co-discover of the...

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
These are great maps. First, there is MIMIC which I show all the time.
I just found this which shows real-time ocean currents.
The main heat energy goes up the middle of the Pacific, so you can see why California is in drought all the time. As I have said, the ocean currents are the real heat pumps of the earth, and weather just follows along. Such an

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 [...]

I am just back from a whirlwind trip to the AGU Meeting in San Francisco. 25,000 Earth scientists in one place, and it’s among the largest science meetings on the planet. I shot some videos that I will post over the weekend, but in the meantime here is a talk I made in October 2013 (in Washington) as part of the AGU Science Speaker
NASA’s Suomi Satellite has an amazing sensor that can see the Earth at night very well. The pics below are a comparison of normal city lights from space, and the green shows the added lights from all the holiday decorations! Pretty cool ay! NASA has a video here and the pics of our region are below. Here are further details from NASA: With a new look at daily data from

Research takes Earth scientists to the four corners of globe. So, if you happen to have a keen interest in photography and find yourself doing research at high latitudes, chances are you’ll get lucky and photograph the dancing night lights: aurora (or northern lights), arguably one of the planet’s most breath taking natural phenomenon. That is exactly the position Matias Takala, a researcher at the Finnish Meteorological Institute (FMI), was in when he was able to take this incredible [...]
“For a thousand years in your sight are but as yesterday when it is past, or as a watch in the night.” — Psalm 90:4 (ESV) Christians disagree with one another about the age of the Earth and the universe. Some Christians insist that the only possible way to interpret the opening chapters of Genesis
