GeoPolicy: What was decided from the Paris COP21?

Last week saw the world’s leaders come together in Paris for the 21st ‘Conference of the Parties’ (aka COP21) to discuss climate change. The 12 day meeting saw over 50,000 participants (half of which from Government organisations) come to reach an agreement on limiting greenhouse gas (GHG) production. Background Manmade climate change, resulting from the increased production of GHG into the atmosp ...[Read More]

The first volcanic eruption to be photographed?

The first volcanic eruption to be photographed?

In the digital era of instant communication, breaking news of volcanic eruptions usually arrive image-first. This year, spectacular eruptions of Calbuco (Chile), Fuego (Guatemala) and Etna (Italy) have all made it into the end-of-year ‘top tens‘, in glorious multicolour detail. But when was the first photograph taken that captured one instant during a volcanic eruption? And which was t ...[Read More]

Geoscience hot topics – Part II: the Earth as it is now and what its future looks like

Geoscience hot topics – Part II: the Earth as it is now and what its future looks like

What are the most interesting, cutting-edge and compelling research topics within the scientific areas represented in the EGU divisions? Ground-breaking and innovative research features yearly at our annual General Assembly, but what are the overarching ideas and big research questions that still remain unanswered? We spoke to some of our division presidents and canvased their thoughts on what the ...[Read More]

EGSIEM wants to use GRACE gravity field data for operational flooding and drought management

EGSIEM wants to use GRACE gravity field data for operational flooding and drought management

The terrestial water cycle leaves traces in the Earth’s gravity field The current onset of el Nino is raising hope in California to replenish some of its multiyear water deficit. Due to the warm pool of water on the East side of the Pacific, more rain, and consequently also larger potential for flooding is expected. At the other side of the Pacific, the water is colder than usual leading to ...[Read More]

The Sustainable Geoscientist – how many papers should academics really be publishing?

The Sustainable Geoscientist – how many papers should academics really be publishing?

In this guest blog post, Nick Arndt, Professor at the Institut des Sciences de la Terre, Grenoble University, reflects on the pressures on academics to publish more and more papers, and whether the current scientific output is sustainable. Imagine a highly productive car factory. Thousands of vehicles are built and each is tested as it leaves the factory; then it is stored in an enormous parking l ...[Read More]

The Panamanian Isthmus is not entirely guilty after all!

The Panamanian Isthmus is not entirely guilty after all!

  “According to new research, the land bridge connecting Central and South America rose more than 10 million years earlier than originally thought”   Traditionally, closure of the Panama Isthmus has been deemed responsible for the co-occurrence of two major events: The large Pleistocene glaciations and the Great American Biotic Interchange (GABI). Existing evidence indicating a ca ...[Read More]

Imaggeo on Mondays: Annapurna snow avalanche

The Annapurna massif is located in an imposing 55 km long collection of peaks in the Himalayas, which behave as a single structural block. Composed of one peak (Annapurna I Main) in excess of 8000 m, a further thirteen peaks over 7000 m and sixteen more of over 6000 m, the massif forms a striking structure within the Himalayas. Annapurna I Main, the tenth highest peak in the world, is towering at ...[Read More]

GeoTalk: Anastasia Tezari – understanding space weather

Weather – it dictates the clothes we wear, is engrained in our culture, shapes our seasons and plays an important role in our daily lives. Not only that, its long term forecast and understanding of its variability, is the focus of much research as it holds one of the keys to understanding the Earth’s past and future. Earthly weather has an altogether less familiar, but not less fascinating a ...[Read More]

Image of the Week: Changes in Snow Cover

Who is dreaming of a white spring? In daily life we might be more interested in the chances of a white Christmas, but the amount of snow-covered ground in the spring is a very good indicator of climate change. The figure above shows the projected change in snow cover extent in the Northern hemisphere in March-April according to different future scenarios (i.e. Representative Concentration Pathways ...[Read More]
