Climate: Past, Present & Future

New metric to interpret linear trends from short time series: Trend to variability ratio (TVR)

March 17, 2021

Availability of good quality data is essential to deduce meaningful information in all disciplines of science and technology. This statement is especially relevant in climate research, which is under constant scrutiny from sceptics. In order to better understand the Earth system response to the ongoing anthropogenic global warming, we require global observations of climate indicators at ver ...[Read More]

Tips on engaging outside of your echo chamber

authored by Dr Martin Archer, edited by Luke Barnard February 10, 2021

In my previous blog, I highlighted that public engagement needs to go beyond traditional approaches such as lectures, since these tend to only attract audiences who are already highly interested in science. However, our science is relevant to (and funded by) everyone, so we have a duty to engage beyond simply this “scientific echo chamber”. But how do you even approach attempting this? It seems li ...[Read More]

What’s my age again? Comparing dating methods in loess

Janina Nett, Sonja Berg, Christian Zeeden and Stephanie Scheidt February 9, 2021

As you have learned from our previous posts, loess is a widespread terrestrial sediment, known to be an important archive for the changes of past environmental and climatic conditions. In order to use loess as a proxy, we first need to investigate the age of the sediments. In loess, different dating methods can be used, such as luminescence dating, radiocarbon dating, magnetic stratigraphy, and or ...[Read More]

Imaggeo On Monday: Transit of Venus over the Sun

Eliza Teodorescu February 8, 2021

The object of this photo is the transit of planet Venus in front of the Sun which took place on June 6th 2012 and was the last event of this kind until 2117! This is a very rare event with respect to a human life span and the transit always happens in pairs, 8 years apart, with a repeatability of more than two centuries. The picture was captured on the shore of the Black Sea, in Vama Veche, Romani ...[Read More]

Winners of the EGU Best Blog Posts of 2020 Competition

Hazel Gibson February 5, 2021

2020 was a brilliant year for our blogging network here at EGU. Across the EGU’s official blog, GeoLog, as well as the network and division blogs there were so many interesting, educational and just downright entertaining posts this year it was hard to get the blog editors to choose their favourites! Nevertheless at the beginning of January, to celebrate the excellent display of science writing ac ...[Read More]

Thermodynamics and Geodynamics: The perfect couple?

Bob Myhill and edited by Menno Fraters January 27, 2021

In preparation for Valentines day, Bob Myhill explores the potential for close partnership (and even love?) between the geodynamics and thermodynamics communities. Much of Earth and planetary science relies in some way on thermodynamics. This is not a surprise; the elegance1 of its premises makes thermodynamics a robust starting point for many investigations, and the number of thermodynamic applic ...[Read More]

Features from the Field: Shear Zones and Mylonites

Samuele Papeschi, Sandra McLaren and Hannah Davies January 25, 2021

The San Andreas Fault in California, the Alpine Fault in New Zealand, or the Main Frontal Thrust in the Himalayas are some of the most famous and largest fault zones that accommodate the relative displacement between two adjacent crustal blocks. Such faults, however, represent only the shallower expression of something much bigger: a crustal shear zone. In the first 10 kilometers or so of the crus ...[Read More]

Image of the Week – Icebergs increase heat flux to glacier

Ben Davison January 15, 2021

Icebergs are ubiquitous in Greenland’s fjords, melting and releasing freshwater as they float towards the open ocean. The amount of freshwater released from these icebergs can be vast – the equivalent of around 50,000 Olympic swimming pools per day in some fjords. New research reveals that this freshwater causes fjord currents to speed-up, which can actually increase the amount of heat delivered t ...[Read More]
