What are erc and erc synergy grants

What are ERC and ERC Synergy Grants

  • Synergy Grants “The strength of the Synergy Grant lies in enabling up to four top scientists to jointly tackle a challenging problem where none of them could succeed alone”

  • 449 proposals, 20 selected for interviews -> 13 were funded (i.e. 3% success rate)

  • Ice2Ice is the only ERC Synergy project in the Nordic countries. Denmark-Norway collaboration

  • Ice2Ice – 12.5 mill EUR for 5 year project. Start August 1, 2014

  • Why synergy?

    • Very complex problem with large potential impacts

    • Need complementary competence from different teams

    • Can exchange between institutions

    • No other mechanism available for a project like this

    • Need such an instrument for difficult questions on important topics


Ice2ice summary

ice2ice summary

  • The Arctic cryosphere is in rapid transformation.

  • Risk of concomitant abrupt change in Arctic sea ice and Greenland ice sheet is not tackled by any existing research program

  • We know such events have happened in the past.

  • We don´t not know why sea ice abruptly disappeared despite cold surroundings.

  • Abrupt changes will lead to immediate global effects on climate and on sea level.

  • The complexities of the problem must be tackled through a broad and in-depth interdisciplinary approach extracting synergies from different fields of expertise.

  • This effort requires world class expertise, laboratories and modelling tools.

  • No institution can do this alone– but we can do this together, given ERC-Synergy resources.

  • The Ice2Ice teams are uniquely positioned to undertake such an effort.

…there is low confidence and little consensus on the likelihood of such events over the 21st century.

Research goals

Research goals

Describe nature, timing and extent of abrupt events across climate archives

Determine the impact of Arctic sea ice

on climate and the Greenland ice sheet

Abrupt changes in Arctic ice?

Resolve mechanisms behind sudden demise of Arctic sea ice cover

Identify risk that rapid diminution of Arctic sea ice could give future abrupt changes


I ce2ice legacy
