2018 ISMASS Paper in Nature Climate Change: 'The Greenland and Antarctic ice sheets under 1.5°C global warming'

A review of ice sheets in a 1.5°C warmer world (a new recent climate mitigation target highlighted by the Intergovernmental Panel on Climate Change) suggests that current predictions of future changes in ice-sheet mass balance are questionable due to incomplete understanding of atmospheric circulation changes around Greenland and ocean circulation around Antarctica. However, the study concludes it is important to limit global warming by 2100 to 1.5°C to maximise the chance of avoiding so-called tipping points that would dramatically accelerate mass loss.

Today, sea level rises at a pace of around 4mm per year and is accelerating. The major contributions to this rise are due to ocean expansion, melting glaciers and – becoming increasingly important – melting of the Greenland and Antarctic ice sheets. Those ice sheets are commonly considered as the ‘sleeping giants’ on Earth, as together they can potentially lead to sea-level rise by more than 70 metres over thousands of years.

Despite improved observations and computer model simulations since the IPCC’s Fifth Assessment Report (AR5) published in 2013, the review highlights some lingering key gaps in knowledge regarding climate forcing of the ice sheets and their resulting responses. On longer time scales, both ice sheets may reach tipping points above around a 1.5-2.0°C limit, leading to irreversible mass loss. For Greenland this is due to increased melting of the ice sheet, while for Antarctica this is due to marine instabilities of certain sectors of the ice sheet, in particular the West Antarctica ice sheet. This would lead to multi-metre sea level rise on centennial to millennial time scales, which has existential consequences for small island states and coastal cities across the world.

Lead author Prof. Frank Pattyn said “Limiting global atmospheric warming to 1.5°C will avoid short and long-term surprises coming from both ice sheets and significantly reduce adaptation cost when global sea-level rise is limited and not catastrophic”.

The paper “The Greenland and Antarctic ice sheets under 1.5°C global warming” is published in Nature Climate Change.  This work has been carried out in the framework of ISMASS (Ice Sheet Mass Balance and Sea Level expert group supported by SCAR/CliC/IASC)

https://bit.ly/2oOOdre

The SSG currently comprises 9 researchers from around the world with a wide range of expertise in global cryosphere observation and modelling. The SSG guides CliC’s priorities and activities, working together with the SSG co-chairs and the CliC project office. SSG members should thus have a good overview of the CliC science plan: https://bit.ly/2oOPCy0 relevant regional and international research agendas, and how CliCs priorities align with those of the new WCRP strategy.

The deadline for nominations is 15 October 2018. Scientific expertise, career stage as well as gender and geographical balance are taken into account. Initial membership is for four years and, as a rule, two extensions of two years each may be recommended. The SSG typically meets once a year.

Call to host the WCRP International Project Office for the Climate and Cryosphere

cliclogo1The World Climate Research Programme is soliciting offers to host an International Project Office (IPO) to coordinate its cryospheric activities from 1st January 2019 onward.

Prospective host institutions and sponsoring organizations are invited to download the full call for hosting the CliC IPO. Letters of intent to host the CliC IPO should be sent to Dr Mike Sparrow () by 1st September 2018. The one-page form for expressions of interest is included in the above-referenced document. General enquiries are welcome under the same email address.

Background information:

The Climate and Cryosphere Core Project (CliC) of the World Climate Research Programme (WCRP) serves as the focal point for climate science related to the cryosphere, its variability and change, and interaction with the broader climate system.

All WCRP IPOs, including CliC, will play a paramount role in refining and implementing WCRP’s upcoming 2019-2029 strategy, including their own strategic contributions to the programme.

CliC activities have resulted in a wealth of cutting-edge research, valuable data products, and innovative use of models to project changes in the Polar Regions and other frozen areas globally.

Past host institutions of the CliC office have consistently benefited from elevated international exposure as well as increased leverage in national and international funding and partnership opportunities. The CliC International Project Office can act as a focus for cryosphere research in its host institution and country and through its network, infrastructure and expertise, can facilitate international research collaboration.

Polar Organisations provide travel support for ECRs to attend POLAR2018

polar18 apecs travelawardsIn February 2018, the Association of Polar Early Career Scientists (APECS) in cooperation with the International Arctic Science Committee (IASC), the Scientific Committee on Antarctic Research (SCAR), the Tinker Foundation, the US National Science Foundation, the University of Alaska Fairbanks, the UK Science & Innovation Network Nordics, the Antarctic Science Ltd. and the Climate and Cryosphere (CliC) Project of the World Climate Research Programme (WCRP) announced the availability of travel awards for POLAR2018 (15 - 26 June 2018, Davos, Switzerland), including Arctic Science Summit Week 2018 & IASC Business Meetings, XXXV SCAR Biennial Meetings, SCAR/IASC Open Science Conference, and 2018 Arctic Observing Summit.

We received a total of 346 applications for this process and due to the high quality of the applications it was very difficult to make a decision. All applications were reviewed by two reviewers each via a blind review process. Final recipients were then determined from the resulting ranked list keeping in mind as wide as possible country spread.

Through this generous financial support from all contributing organizations, we were able to fund 91 applicants from 27 countries (Australia, Austria, Belgium, Brazil, Canada, Chile, China, Czech Republic, Denmark, France, Germany, Iceland, India, Italy, Japan, New Zealand, Norway, Poland, Portugal, Russia, South Africa, South Korea, Spain, Sweden, Turkey, the United Kingdom and the United States). All recipients have been notified and have accepted their awards. Congratulations to all recipients!

Thank you again to all the funders for making this incredible support possible. Also a big thank you to the reviewers who took their time to help us evaluate all these applications.

We are looking forward to seeing many of you in Davos!
