GeoSciences Column: When could humans last walk, on land, between Asia & America?

Though now submerged under 53 m of ocean waters, there once was a land bridge which connected North America with Asia, allowing the passage of species, including early humans, between the two continents. A new study, published in the EGU’s open access journal Climate of the Past, explores when the land bridge was last inundated, cutting off the link between the two landmasses. The Bering Strait, a ...[Read More]

The Rainbow Colour Map (repeatedly) considered harmful

This week’s “Wit and Wisdom” post is a guest entry by researcher Fabio Crameri from the Centre for Earth Evolution of Dynamics (CEED), University of Oslo. Many of us are guilty of creating figures using the colours of the rainbow in their full glory – it’s bold, exciting, and justifies the golden data contained within, right? Wrong! As Fabio explains, the rainbow scheme is misleading and should be ...[Read More]

Imaggeo on Mondays: A total eclipse of the Moon

Today, all eyes are turned to the sky; at least in North America, where the region will be treated to an eclipse of the sun. The online hype is hard to miss and its hardly surprising, opportunities to see the moon completely cover the Sun, where you are, are rare*. According to NASA, the same spot on Earth only gets to see a solar eclipse for a few minutes about every 375 years! If like us, you ca ...[Read More]

Image of the Week – See sea ice from 1901!

The EGU Cryosphere blog has reported on several studies of Antarctic sea ice (for example, here and here) made from high-tech satellites, but these records only extend back to the 1970s, when the satellite records began. Is it possible to work out what sea ice conditions were like before this time? The short answer is YES…or this would be a very boring blog post! Read on to find out how hero ...[Read More]

The eastern Mediterranean: What’s in a name?

Every 8 weeks we turn our attention to a Remarkable Region that deserves a spot in the scientific limelight. To kick off this series, Anne Glerum introduces us to the eastern Mediterranean, which has been a natural laboratory for generations of scientists. The name of our Remarkable Region is quite descriptive: it designates the region around and including the eastern part of the Mediterranean Sea ...[Read More]

The 2017 solar eclipse and scientific discoveries

The next solar eclipse is upon us. On August 21 the moon will pass between the Sun and an observer’s point of view in America and block out daylight, creating an eerie gloom in the sky. The transit of the moon between the Earth and Sun occurs about every 18 months, but for your particular city it can take several hundreds of years before a new eclipse occurs. The figure below shows the paths of al ...[Read More]

GeoTalk: Meet the EGU’s President, Jonathan Bamber

GeoTalk interviews usually feature the work of early career researchers, but this month we deviate from the standard format to speak to Jonathan Bamber, the EGU’s President. Jonathan has a long-standing involvement with the Union, stretching back almost 20 years. Following a year as vice-president, Jonathan was appointed President at this year’s General Assembly in Vienna. Here we talk ...[Read More]

Image of the week – Micro-organisms on Ice!

The cold icy surface of a glacier doesn’t seem like an environment where life should exist, but if you look closely you may be surprised! Glaciers are not only locations studied by glaciologists and physical scientists, but are also of great interest to microbiologists and ecologists. In fact, understanding the interaction between ice and microbiology is essential to fully understand the gla ...[Read More]

New Dimensions for Natural Hazards in Asia: the first AOGS–EGU Joint Conference

New Dimensions for Natural Hazards in Asia: the first AOGS–EGU Joint Conference

Asia is one of the most natural disaster-prone regions on the globe. Overpopulation and limited resources mean that natural hazards hit local populations particularly hard. “It doesn’t matter which index or evaluation method you use, Asia will always unfortunately come out on top when it comes to fatalities and damage from natural hazard events,” explains Dr. Adam Switzer, a member of the conferen ...[Read More]
