The call for papers for 'A Connected Ocean (ACO): The challenge of observation data integration' has been extended to 25 June 2016. For information on the sessions and how to register please see the AOC 2016 Conference Website.
Deadline for registration extended to 30 July 2016
The GEWEX Hydroclimatology Panel (GHP) and Global Land/Atmosphere System Study (GLASS) are hosting a workshop on anthropogenic influences on the global water cycle. Join us at the CNRS campus in Gif-sur-Yvette, France from 28-30 September 2016 for a meeting on representing the human dimension in land-surface models (LSMs). GLASS and GHP, both GEWEX Panels, have launched a cross-cutting initiative that promotes the inclusion of human processes in LSMs and broadens GEWEX’s current consideration of anthropogenic influences. You can read more about the initiative in the November issue of GEWEX News. Workshop attendance is limited to 50 participants. We advise those interested in attending to register early.

OPEN ACCESS: Decadal prediction simulations of Niño3.4 sea surface temperatures show a transition from positive to negative phases of the Interdecadal Pacific Oscillation (IPO) and a resumption of larger rates of global warming over the 2013–2022 period consistent with a positive IPO phase. For more see: Meehl, G. A. et al. 2016. Initialized decadal prediction for transition to positive phase of the Interdecadal Pacific Oscillation. Nat. Commun. 7:11718 doi: 10.1038/ncomms11718.

The recent El Niño event has elevated the rise in CO2 concentration this year. Using emissions, sea surface temperature data and a climate model, the authors forecast that the CO2 concentration at Mauna Loa will for the first time remain above 400 ppm all year, and hence for our lifetimes. For more see: Betts, R. A. et al. 2016. El Niño and a record CO2 rise, Nature Climate Change. doi:10.1038/nclimate3063.

OPEN ACCESS: Large-scale atmospheric circulation controls the mass and energy balance of the Greenland ice sheet through its impact on radiative budget, runoff and accumulation.
