Arctic Resilience Interim Report 2013 released
The report, led by the Stockholm Environment Institute and the Stockholm Resilience Centre at Stockholm University, considers how changes in climate, ecosystems, economics, and society interact. In addition to the full report, a summary for policymakers is available.

Vast costs of Arctic change
Methane released by melting permafrost will have global impacts that must be better modelled, say scientists from Erasmus University Rotterdam and University of Cambridge in a recent comment in Nature.

Important role for ocean warming and increased ice-shelf melt in Antarctic sea-ice expansion
Unlike in the Arctic, Antarctic sea-ice has expanded. Whereas this has previously been attributed to dynamical atmospheric changes that induce atmospheric cooling, scientists from the Royal Netherlands Meteorological Institute (KNMI) show that accelerated basal melting of Antarctic ice shelves is likely to have contributed significantly to sea-ice expansion.

EURO-CORDEX: new high-resolution climate change projections for European impact research
Scientists at the Climate Service Center (CSC) and Max Planck Institute for Meteorology (MPIM), Germany and others completed the first set of simulations with a horizontal resolution of 12.5 km for the new emission scenarios RCP4.5 and RCP8.5 with more simulations expected to follow. The EURO-CORDEX ensemble results have been compared to the SRES A1B simulation results achieved within the ENSEMBLES project: they differ in regional details.

Observed mean sea level changes around the North Sea coastline from 1800 to present assessed
In a recent study, Scientists from the University of Siegen, Germany, and others analysed long records of up to 200 years from 30 tide gauge sites. They calculated relative sea level trends, examined the inter-annual and decadal variations, estimated regional geocentric sea level rise throughout the 20th century and assessed the evidence for regional acceleration of sea-level rise.

The North Atlantic Ocean drives the weather
Scientists from the Shirshov Institute of Oceanology, Russia, GEOMAR, Germany, Bjerknes Centre for Climate Research, Norway, and others, recently proved what Jacob Bjerknes, the father of modern weather forecasting, suggested as early as 1967: that the North Atlantic controls the surface heat flux over Europe on multidecadal timescales.

high resolution data
Bayesian assessment of horizontal resolution in a nested-domain WRF simulation
With the need for high-resolution data and producing it using a limited area model comes the constraint of limited computing resources. Scientists at the Bjerknes Centre for Climate Research, Norway and others now put forward an alternative approach to analysing output from limited area models based on Bayesian probability.
