Extremely high temperatures pose an immediate threat to humans and ecosystems. In recent years, many regions on land in the ocean experienced heat waves with devastating impacts that would have been highly unlikely without human-induced climate change. Impacts are particularly severe when occur exposure of people or crops. The 2018 spring-to-summer season was characterized by several major dry extremes. On daily average between May July about 22% populated agricultural areas north 30°...
Abstract. This article extends a previous study Seneviratne et al. (2016) to provide regional analyses of changes in climate extremes as function projected global mean temperature. We introduce the DROUGHT-HEAT Regional Climate Atlas, an interactive tool analyse and display range well-established water-cycle indices their warming. These projections are based on simulations from fifth phase Coupled Model Intercomparison Project (CMIP5). A selection example results presented here, but users...
In this study, we investigate changes in temperature and precipitation extremes over West Central Africa (hereafter, WAF domain) as a function of global mean with focus on the implications warming 1.5 °C 2 according Paris Agreement. We applied scaling approach to capture climate increase several subregions within domain: Western Sahel, Eastern Guinea Coast including Congo Basin.
This article investigates projected changes in temperature and water cycle extremes at 1.5°C of global warming, highlights the role land processes land-use (LUCs) for these projections. We provide new comparisons climate versus 2°C based on empirical sampling analyses transient simulations from ‘Half a degree Additional Prognosis Projected Impacts’ (HAPPI) multi-model experiment. The two approaches yield similar overall results regarding land, reveal substantial difference occurrence...
Actual land evapotranspiration (ET) is a key component of the global hydrological cycle and an essential variable determining evolution extreme events under different climate change scenarios. However, recently available ET products show persistent uncertainties that are impeding precise attribution human-induced change. Here, we aim at comparing range independent monthly estimates with historical model simulations from water, agriculture, biomes sectors participating in second phase...
Abstract Many countries rely on regional climate model (RCM) projections to quantify the impacts of change and design their adaptation plans accordingly. In several European regions, RCMs project a smaller temperature increase than global models (GCMs), which is hypothesised be due discrepant representations topography, cloud processes, or aerosol forcing in GCMs. Additionally, do generally not consider vegetation response elevated atmospheric CO 2 concentrations; process is, however,...
High-resolution climate reconstructions from a range of natural archives across the world are fundamental to place current change into perspective. Paleoclimate records for Southern Hemisphere scarce and only few quantitative high-resolution exist past millennium. We present record annually laminated sediments Lago Plomo (46°59′S, 72°52′W,203 m a.s.l.) located east Northern Patagonian Ice Field (NPI). Radiometric dating ( 210 Pb, 137 Cs, 14 C AMS) is consistent with counts millimetre-scale...
Abstract. Historical, i.e. pre-1957, upper-air data are a valuable source of information on the state atmosphere, in some parts world dating back to early 20th century. However, date, reanalyses have only partially made use these data, and observations after 1948. Even for period between 1948 (the starting year NCEP/NCAR (National Centers Environmental Prediction/National Center Atmospheric Research) reanalysis) International Geophysical Year 1957 ERA-40 reanalysis), when global coverage...

Between April 1925 and June 1927, the research vessel Meteor cruised tropical southern Atlantic Ocean in framework of German Expedition.One purpose was to systematically explore vertical structure atmosphere.To this end, ocean crossed 14 profiles across parallels latitude.801 pilot balloons 217 kites were launched.The resulting data have been digitised European project ERA-CLIM.Here, they are compared Twentieth Century (20CR) ERA-20C reanalyses, independent datasets based on assimilation...
