"it is likely that impacts of overshooting 1.5C on the Antarctic ice sheet worsen with increasing magnitude and duration and may be long-lasting if not irreversible" Ann Kristin Klose closing her brilliant talk on overshoot scenarios for @H2020PROTECT
#IGSnorthumbria2024

The essential update from Hilmar Guðmundsson on #Thwaites, #PineIsland and other glaciers in the Amundsen Sea sector. This is work related to #Tippaccs + @OceanIceEU TL;DR MICI probably isn't a thing, the Thwaites ice shelf is irrelevant to the glacier but grounding lines are probably going to be important...
#IGSnorthumbria2024

Very interesting conclusions from Christine Hvidberg - we can already detect dynamic changes in the interior of #Greenland that is attributable to thinning and retreat in the coastal margins. Measurable by an epic thirty year GPS record as well as #ESAcci satellite observations
#IGSnorthumbria2024

My ace colleague from Copenhagen University, and PI on #PRECISE Christine Hvidberg presenting some new insights from GPS at the #IceCore sites on #GreenlandIceSheet dynamics at #IGSnorthumbria2024

And on to that other great unknown: @fsmccormack.bsky.social taking us through geothermal heatflux and it's role in basal melting under the #AntarcticIceSheet at #IGSnorthumbria2024

I sometimes dread the rheology session but this has been a really good one #IGSnorthumbria2024.Quite clear that combination of good satellite data together with advances in #ML tools has really led to something of a leap forward in better understanding how and where ice flows like it does.

Re last post it might seem extremely arcane if the exponent in the ice flow law is 3 or 4 but now the 3rd speaker at #IGSNorthumbria2024 is pointing out that the small change in one number can lead to 30% higher ice loss from marine terminating glaciers like Thwaites and Pine Island. Details matter

We tend to think we know a lot about ice. And this is true, but Ching Yao Lai from Stanford has a great slide summarising all the stuff that makes the rheology of ice and how it flows difficult to measure. #IGSnorthumbria2024

Kicking off day 3 of the #IGSnorthumbria2024 with some hard core* ice physics, Brett Minchew presenting some cool** stuff on Glen's Law and implications for the exponent n.

*Pun absolutely intended

**And that one.

Discussions on #Ismip7 - the #IceSheet MIP for #CMIP7 at #IGSnorthumbria2024 this afternoon - it's an interesting process to go through (again). #SMB will be a part of it, but further discussions needed.
One things for sure, we as a #polarClimate #glaciology community are going to be busy...

Not a surprise, the global #permafrost area is declining...

Conclusions from Harley McCourt #IGSnorthumbria2024

An update on the state of global #permafrost from Harley McCourt at #IGSNorthumbria2024

Georgina Woolley on #Arctic #Snowpack processes in models. A really interesting problem I'm hoping to work on more in the next few years. #snow affects everything from land to sea ice to glaciers...
#IGSnorthumbria2024

On to Nicole Schlegel presenting a very cool new #polar mission - #PREFIRE measuring far infrared radiation - a small #CubeSAT type mission focused in the #Arctic with a 10-12 month timescale #IGSnorthumbria2024

Gave a talk on differences in #SMB projections that emerge over the century for the @h2020protect.bsky.social @H2020PROTECT project at #IGSnorthumbria2024 this morning.
May blog it later

The brilliant @treacherousbuzz.bsky.social presenting her latest work on #IceShelf hydrology and lakes. #IGSnorthumbria2024

Trying out openvibe as a cross platform posting option during #IGSnorthumbria2024. Let's see if this works?

Modellers often take the "one number" approach when there is a dataset, but this can be a bit tricky, Andreas Werneke (with @lavergnetho ) presenting @osi_saf data and uncertainty in its use for evaluating models at #IGSNorthumbria2024

Really excellent talk by my @H2020PROTECT collaborator Sebastian Simonsen of @dtuspace on how we can better use #EO and satellite data for #IceSheet mass budget studies using #ML methods #AI.

#IGSNorthumbria2024

I'm off to the #IGSnorthumbria2024 symposium on verification and evaluation of #cryosphere models - presenting results from our @H2020PROTECT models of #Greenland and #Antarctic #IceSheet #SMB.

If you're there, give me a shout; if there's anything you want to know about the world of #cryosphereModelling then ask away and I'll try to find out for you if I don't know.
