They come in all shapes, sizes and textures. They can be white, deep blue or brownish. Sometimes they even have penguins on them. It is time to (briefly) introduce this element of the cryosphere that has not been given much attention in this blog yet: icebergs! What is an iceberg? Let’s start with the basics. …[Read More]
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 …[Read More]
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 …[Read More]
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 …[Read More]
The 2017 edition of the EGU general assembly was a great success overall and for the cryospheric division in particular.

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 …[Read More]
