Defrosting the freezer. Climate change and glacial meltwater

Defrosting the freezer. Climate change and glacial meltwater

 Why are glaciers important? Glaciers cover around 10% of the global land surface. This includes the large ice sheets (e.g. in Greenland and Antarctica) as well as smaller ice caps and valley glaciers (e.g. in Iceland, Norway and New Zealand). Figure 1 shows the current distribution of glaciers around the world. Figure 1 – The global distribution of glaciers around the world from the GLIMS glacier ...[Read More]

Image of the Week – Antarctica’s Flowing Ice, Year by Year

Image of the Week – Antarctica’s Flowing Ice, Year by Year

Today’s Image of the Week shows annual ice flow velocity mosaics at 1km resolution from 2005 to 2016 for the Antarctic ice sheet. These mosaics, along with similar data for Greenland (see Fig.2), were published by Mouginot et al, (2017) last month as part of NASA’s MEaSUREs (Making Earth System Data Records for Use in Research Environments) program. How were these images constructed? The mosaics s ...[Read More]

Folding and Fracturing of Rocks – 50 years of research since the seminal textbook of JG. Ramsay

Folding and Fracturing of Rocks – 50 years of research since the seminal textbook of JG. Ramsay

John G. Ramsay1 wrote his seminal textbook on the folding and fracturing of rocks in 1957, almost 20 years before I was born (and I don’t count myself as young!). So why did I co-convene a session at EGU in 2017 to celebrate the book? Because the book, in many ways, expresses the legacy that John has given to structural geology. He followed it with a series of books of the same ilk – Ramsay ...[Read More]

Image of the Week – A rather splendid round-up of CryoEGU!

The 2017 edition of the EGU general assembly was a great success overall and for the cryospheric division in particular. We were for instance thrilled to see that two of the three winning photos of the EGU Photo contest featured ice! To mark the occasion we are delighted to use as our image of this week,  one of these pictures, which  shows an impressive rapid in the Pite River in northern Sweden. ...[Read More]

Hot towns, summer in the city!

Hot towns, summer in the city!

Cities obviously experience a different climate than natural landscapes. Already in 1810 the British meteorologist Luke Howard documented that the air temperature in the city of London was several degrees higher than in its surroundings. This so called urban heat island has several causes. In general the relatively dark surfaces of asphalt and roofs absorb solar radiation very efficiently and this ...[Read More]

You’re an early career scientist and you want to go somewhere… but where?

Only a few more days and the General Assembly of the EGU 2017 will start! Five exciting days with science and the opportunity to meet your colleagues and collaborators, both the old and the new. Earlier this week the outgoing TS President Susanne Buiter and the incoming TS President Claudio Rosenberg posted a blog with TS highlights, but what are the must-see for the Early Career Scientists? This ...[Read More]
