Ice-hot news: The IPCC Special Report on the Oceans and the Cryosphere under Climate Change

Ice-hot news: The IPCC Special Report on the Oceans and the Cryosphere under Climate Change

You have probably heard the name “Intergovernmental Panel on Climate Change (IPCC)” mentioned frequently over the last few years. The IPCC is the United Nations body for assessing science related to climate change and it publishes global assessment reports on this topic every 5 to 10 years. Due to the current urgency of the global climate crisis and the need for more information by decision makers ...[Read More]

Cryo-Comm – Capturing Ice

In this week’s blogpost, author, editor, artist, and outreach expert Marlo Garnsworthy gives some insights into her recent trip to Iceberg Alley, gives you some tips on how to communicate icy science, and shows us her inspirational artwork. If you’re reading this, ice may be on your mind. Ice is surely on mine. During my day job as a creative and editor, I dip frequently into Twitter for the lates ...[Read More]

Cryo-adventures – Life and science at a central Greenland ice core drilling camp

Cryo-adventures – Life and science at a central Greenland ice core drilling camp

How do you get there? Where will you sleep? What work will you do there?These are just a few of the many questions I got from family and friends when I told them that I would join the EastGRIP ice core project this summer. As a paleo climate and ice sheet modeller, I could only repeat the abstract information given to me, very conscious that I actually had no idea how it would be to live and work ...[Read More]

Image of the Week – The GReenland OCEan-ice interaction project (GROCE): teamwork to predict a glacier’s future

The GROCE project, funded by the German Ministry for Education and Research (BMBF), takes an Earth-System approach to understand what processes are at play for the 79°N glacier (also known as Nioghalvfjerdsfjorden), in northeast Greenland. 79°N is a marine-terminating glacier, meaning it has a floating ice tongue (like an ice shelf) and feeds into the ocean. Approximately 8% of all the ice contain ...[Read More]

Image of the Week – Kicking the ice’s butt(ressing)

Changes in the ice shelves surrounding the Antarctic continent are responsible for most of its current contribution to sea-level rise. Although they are already afloat and do not contribute to sea level directly, ice shelves play a key role through the buttressing effect. But which ice shelf regions are most important for this? The role of ice-shelf buttressing In architecture, the term “buttress” ...[Read More]

Image of the Week — Into Iceberg Alley

Crew in hardhats and red safety gear bustle about, preparing our ship for departure. A whale spouts nearby in the Straits of Magellan, a fluke waving in brief salute, before it submerges again. Our international team of 29 scientists and 2 science communicators, led by co-Chief Scientists Mike Weber and Maureen Raymo, is boarding the JOIDES Resolution, a scientific drilling ship. We’re about to jo ...[Read More]

The hidden part of the cryosphere – Ice in caves

The hidden part of the cryosphere – Ice in caves

The cryosphere can be found in various places in many forms and shapes… in the atmosphere, on land and sea. A lesser known part of the cryosphere is hidden deep in the dark, in the cold-karstic areas of the planet: Ice caves! The ongoing climate change affecting ice all over the world is now rapidly melting these hidden ice masses as well. We therefore need to hurry up and try to collect as ...[Read More]

Image of the Week – When “Ice, Ice Baby” puts rocks “Under Pressure”

Bowie and Queen said it first, and Vanilla Ice brought it back. But now, I’ve set out to quantify it: Pressure. Rocks in glacial landscapes can experience many different kinds of pressure (forces), from sources like regional tectonics or even the weight of the glacier itself. Our hypothesis is that smaller-scale pressures, caused by the formation of ice in small bedrock cracks (frost-weathering), ...[Read More]

Image of the Week – Why is ice so slippery?

Having spent most of my life in places where the temperature hardly ever falls below zero, my first winter in Sweden was painful. Especially for my bum, who met the ice quite unexpectedly. Reading the news this week, from reports of emergency services overwhelmed after so many people had slipped to a scientific study on how no shoes have a good enough grip, via advice on how to walk like a penguin ...[Read More]

Image of the Week – Ice-Spy: the launch of ICESat-2

On September 15th, 2018, at 18:02 local time, NASA launched its newest satellite – the second generation Ice, Cloud and land Elevation Satellite (ICESat-2). ICESat-2 only contains one instrument – a space laser that fires 10,000 pulses per second to Earth to measure elevation. Its primary purpose is for monitoring the ever changing cryosphere, so naturally there are plenty of ice enthusiasts ...[Read More]
