We would like to continue the series of ECRA newsletters in 2014!
The ECRA newsletter 1/2014 informs about highlights in climate research, provides news from the European stage as well as internal information from ECRA and Collaborative Programmes as well as interesting upcoming events organized or joined by ECRA.
atmosphere Continued global warming after CO2 emissions stoppage The study uses Earth system model simulations of a stoppage in CO2 emissions to demonstrate that in some models, surface temperature may actually increase on multi-century timescales after an initial century-long decrease. The reason lies in decreasing ocean heat uptake together with feedback effects. read the study
Newly detected ozone-depleting substances in the atmosphere Ozone-depleting substances emitted through human activities cause large-scale damage to the stratospheric ozone layer, and influence global climate. So far, seven types of CFC and six types of HCFC have been shown to contribute to stratospheric ozone destruction. Researchers at the University of East Anglia, UK, now report the detection and quantification of a further three CFCs and one HCFC. read the study
Coverage bias in the HadCRUT4 temperature series and its impact on recent temperature trends Incomplete global coverage is a potential source of bias in global temperature reconstructions if the unsampled regions are not uniformly distributed over the planet's surface. The widely used Hadley Centre–Climatic Reseach Unit Version 4 (HadCRUT4) dataset covers on average about 84% of the globe over recent decades, which suggests that HadCRUT4 is subject to bias, as this study finds. read the study
arctic High temporal resolution estimations of the Arctic sea ice albedo during the melting and refreezing periods of the years 2003-2011 Methods for estimating seasonal and long term trends of the Arctic sea ice albedo are of growing importance to cryosphere and climate studies. Remote sensing of the sea ice albedo using optical satellite instruments is often insufficient, so researchers at the Finnish Meteorological Institute show that a new microwave based sea ice albedo estimation method can alleviate some of the problems. read the study
high impact events Extreme summer weather in northern mid-latitudes linked to a vanishing cryosphere The past decade has seen an exceptional number of unprecedented summer extreme weather events in northern mid-latitudes, along with record declines in both summer Arctic sea ice and snow cover on high-latitude land. This study demonstrates links between these developments. read the study
sea level Rapid changes in the seasonal sea level cycle along the US Gulf coast from the late 20th century A study from the University of South Florida, USA, investigates temporal variations of the seasonal sea level harmonics throughout the 20th and early 21st century along the United States Gulf coast. It finds a significant amplification of the annual sea level cycle from the 1990s onward, most of which can be explained by changes in the air surface temperature toward warmer summers and colder winters and changes in mean sea level pressure. read the study
hydrological cycles Hydrological droughts in the 21st century, hotspots and uncertainties from a global multimodel ensemble experiment Increasing concentrations of greenhouse gases in the atmosphere are expected to modify the global water cycle with significant consequences for terrestrial hydrology. The study assesses the impact of climate change on hydrological droughts in a multimodel experiment and finds a likely increase in the global severity of drought by the end of 21st century. read the study
El Niño–La Niña cycle and recent trends in continental evaporation The hydrological cycle is expected to intensify in response to global warming. Yet, little unequivocal evidence of such an acceleration has been found on a global scale. The study uses satellite observations to reveal that continental evaporation has increased in northern latitudes, while at the global scale, the dynamics of the El Niño/Southern Oscillation (ENSO) have dominated the multi-decadal variability. read the study
european commission 2030 climate and energy goals for a competitive, secure and low-carbon EU economy The European Commission presented in January the pillars of its new framework on climate and energy for 2030, which comprise among others a reduction in greenhouse gas (GHG) emissions by 40% below the 1990 level, an EU-wide binding target for renewable energy of at least 27%, renewed ambitions for energy efficiency policies. read the press release
dg research and innovation Climate Action and Earth Observation: Arctic Research The publication “Arctic Research funded by the European Union” is now available. The brochure reports about polar collaborative research projects funded by the European Union highlighting ongoing activities supported by the Environment (and Climate Change) and the Infrastructure programmes FP7. read the publication
dg climate action Turn to climate action for a job-rich economic recovery, Europeans say Four out of five people in the European Union recognise that fighting climate change and using energy more efficiently can boost the economy and employment, according to a special Eurobarometer opinion poll on climate change published in March. This is slightly higher than in the last poll, in 2011, when 78% agreed. read the press release
european parliament Cooling without climate warming: Parliament backs F-gas ban The use of climate-unfriendly fluorinated gases should be banned in new air-conditioning appliances and refrigerators by 2022-2025, under draft rules approved by the European Parliament in March. These rules had already been informally agreed with EU ministers. Overall, the use of potent hydrofluorocarbon (HFC) greenhouse gases is to be reduced by 79% by 2030. read the press release
statement by the european commission Developments following the Swiss referendum on 9th February Following the Swiss referendum on immigration quotas, the European Commission announced it had suspended negotiations on Switzerland's participation in Horizon 2020 and the Erasmus+ educational exchange programme. read the statement
ECRA Secretary A new Secretary Tina Swierczynski started her work for ECRA at 1st March 2014. The ECRA Executive Committee would like to thank Andreas Krell for his ambitious work in ECRA! New Members Three new members “Bolin Centre-Research Centre for Climate Science” (Sweden); “Institute of Environmental Assessment and Water Research/IDAEA-CSIS (Spain) and “University of Bologna” (Italy), join the network of ECRA in 2014 as participants and will support the four Collaborative Programmes. see list of current members
ECRA-Collaborative Programme “High Impact Events” A joint Workshop of ECRA/Technical University of Denmark (DTU) will take place 2/3 June 2014 in Copenhagen. The workshop aims to engage stakeholders for developing research priorities and will discuss state-of-the-art developments in the science of extreme events. Topics will be: (1) Physics of extreme events, (2) Statistics of extreme events, (3) From models to impacts, (4) Impact studies of past events, (5) Future changes of extreme events. You are welcome to participate and to register now. more information
ECRA-Collaborative Programme “Hydrological Cycles” A joint Workshop of ECRA/Ludwig-Maximilians-Universität (LMU) Munich entitled “Climate and the Ecohydrological Cycle: Filling the Scale Gap” was planned to take place on 24/25 February 2014. This Workshop will be postponed to October. More information will be offered soon.
ECRA-Collaborative Programme “Arctic” The Arctic-ECRA “Strategy and Work Plan” is going to be finalized and was presented at the ECRA-Executive Committee meeting on 13th March 2014 in Brussels. This “Work Plan” is a guideline for the collaborative work of Arctic ECRA in the future. Thanks to all contributors! This plan will be available soon on the ECRA-website: http://www.ecra-climate.eu.
Belmont Forum The Belmont Forum has released a call for proposals on Arctic Observing and Research for Sustainability as part of its 2014 International Opportunities Fund to encourage interdisciplinary and trandisciplinary science. The call seeks to bring together integrated teams of natural scientists, social scientists, and stakeholders to develop projects that utilize existing Arctic observing systems, datasets and models to evaluate key sustainability challenges and opportunities in the Arctic region. Proposals for this funding opportunity are due 31 July 2014. further information
