Humans have altered the Earth’s land surface since Paleolithic mainly by clearing woody vegetation first to improve hunting and gathering opportunities, later provide agricultural cropland. In Holocene, agriculture was established on nearly all continents led widespread modification of terrestrial ecosystems. To quantify role that humans played in global carbon cycle over we developed a new, annually resolved inventory anthropogenic cover change from 8000 years ago beginning large-scale...
Abstract. The major objectives of this paper are: (1) to review the pros and cons scenarios past anthropogenic land cover change (ALCC) developed during last ten years, (2) discuss issues related pollen-based reconstruction land-cover introduce a new method, REVEALS (Regional Estimates VEgetation Abundance from Large Sites), infer long-term records pollen data, (3) present project (LANDCLIM: LAND – CLIMate interactions in NW Europe Holocene) currently underway, show preliminary results...
Abstract For more than a decade, scientists have argued about the warmth of current interglaciation. Was preindustrial late Holocene natural in origin, result orbital changes that had not yet driven system into new glacial state? Or was it considerable degree humans intervening climate through greenhouse gas emissions from early agriculture? Here we summarize evidence moves this debate forward by testing both hypotheses. By comparing responses to those occurred during previous...
Here, we present a community perspective on how to explore, exploit and evolve the diversity in aquatic ecosystem models. These models play an important role understanding functioning of ecosystems, filling observation gaps developing effective strategies for water quality management. In this spirit, numerous have been developed since 1970s. We set off explore model by making inventory among 42 modellers, categorizing resulting analysing them diversity. then focus comparing combining...
Abstract. Wildfire occurrence is influenced by climate, vegetation and human activities. A key challenge for understanding the risk of fires quantifying mediating effect on fire regimes. Here, we explore relative importance Holocene land cover, use, dominant functional forest type, climate dynamics biomass burning in temperate boreo-nemoral regions central eastern Europe over past 12 kyr. We used an extensive data set pollen sedimentary charcoal records, combination with simulations...
Abstract. The unprecedented use of Earth's resources by humans, in combination with increasing natural variability processes over the past century, is affecting evolution Earth system. To better understand and their potential future trajectories requires improved integration quantification human processes. Similarly, to mitigate risk facilitate socio-economic development a understanding how system (e.g. climate change, extreme weather events, soil fertility) affects Our these interactions...
Abstract Marine litter is one of the most relevant pollution problems that our oceans are facing today. in a major threat to sustainable planet. Here, we provide comprehensive analysis cutting-edge solutions developed globally prevent, monitor and clean marine litter. Prevention this research includes only innovative prevent entering seas rather than interventions such as waste reduction recycling. On basis extensive search data compilation, reveals information dispersed across platforms not...
Coastal ecosystems are increasingly experiencing anthropogenic pressures such as climate warming, CO 2 increase, metal and organic pollution, overfishing, resource extraction. Some resulting stressors more direct like pollution fisheries, others indirect ocean acidification, yet they jointly affect marine biota, communities, entire ecosystems. While single-stressor effects have been widely investigated, the interactive of multiple on less researched. In this study, we review literature their...
Abstract. We investigate the extent to which quantities that are based on total column ozone applicable as measures of loss in polar vortices. Such have been used frequently assessments by World Meteorological Organization (WMO) and also assess performance chemistry-climate models. The most commonly considered March October mean poleward geometric latitude 63° spring minimum daily minima a given latitude. Particularly Arctic, former measure is affected vortex variability break-up spring....
Computational models are complex scientific constructs that have become essential for us to better understand the world. Many valuable peers within and beyond disciplinary boundaries. However, there no widely agreed-upon standards sharing models. This paper suggests 10 simple rules you both (i) ensure share in a way is at least “good enough,” (ii) enable others lead change towards model-sharing practices.
The SNS has recently become a European hub for installations of offshore wind farms (OWF), while extensive areas have been designated as marine protected (MPAs). Together with the already noticeable effects climate warming, region transforms from an area dominated by free ranging fisheries and shipping into industrial landscape stationary activities. To inform decision making processes around spatial allocation fisheries, conservation measures licence renewables in southern North Sea, we...

The global industrialization of seascapes and climate change leads to an increased risk severe impacts on marine ecosystem functioning. While broad scale spatio-temporal assessments human pressures ecosystems become more available, future trajectories activities at regional local scales remain often speculative. Here we introduce a stepwise process integrate bottom-up expert-driven approaches for scenario development inform cumulative effects related spatial planning (MSP). Following this...
