Professor of Earth Observation and glaciology at University of Bristol and Technical University Munich. Open Access advocate, sports fanatic, European.

Jonathan Louis Bamber is a British physicist known for his work on satellite remote sensing of the polar regions, and especially the Antarctic and Greenland ice sheets. He has authored more than 200 refereed scientific publications about the cryosphere and its interaction with the rest of the Earth System, and is recognized by the Institute for Scientific Information as a "highly cited researcher". In 2019, he was elected a fellow of the American Geophysical Union "for pioneering satellite remote sensing in glaciology and building bridges to other disciplines of the geoscience community." .. more

Finally out! The outcome of a virtual workshop in Feb 2024 with modelers and observationalists to put together data and protocols to include historical changes in ice sheet/ice shelf discharge in CMIP models. Hopefully not too late for some CMIP7 runs!

Datasets and protocols for including anomalous freshwater from melting ice sheets in climate simulations
Abstract. Anomalous freshwater fluxes from the Greenland and Antarctic ice sheets and ice shelves are impacting the surrounding oceans, and we need to be able to account for these effects in climate m...

You do realise that even posting about this nonsensical paper is giving it visibility and increasing its altmetric score. It was covered by the Times in the UK as well, despite best attempts of experts to set the record straight

Hey you wonderful EO scientists. Why not nominate your amazing colleague or team or nominate yourself for the next ESA EO excellence award. Nominations have just opened and close 10th Dec. Research cash prize for lucky winners:

Totally agree. Every 10th of a degree matters and AGW is not binary but almost every country around the world has declared a climate emergency yet none are treating it like one.

BTW, just saw the news about GISS. Not great.

not overly encouraging...

Sure that's 2 degs. I was referring to 1.5. But, honestly, would I bet on staying below 2 degs right now....?

Yes I know but take a look at the emissions trajectory and it's pretty black and white. It's gone. There is no plausible way to lower emissions sufficiently now...

Looks like staying below 1.5 degs warming is in the rear view mirror. Let's hope that 2 degs doesn't end up the same.

Currently trajectory => dangerous levels of sea level rise from the ice sheets. Will this influence policy? Unlikely, but important to keep banging the drum. As declared by almost all nations: it's an EMERGENCY.
There’s so much happening right now, I thought I’d put together a running thread on the dismantling of #climate and research and knowledge infrastructure in the United States 🧵

A bit naive IMHO. Some of this funding was used for sustainable energy research. Should we boycott BP/Shell/...EV charging stations as that is adding to their profit or should we support their efforts to provide sustainable energy.....

And here's the UoB press release for the paper:

A new study has exposed for the first time the huge loss of glaciers in a global warming hotspot over the past four decades.

It also shows the biggest retreat has occurred in recent years.
