Multiple Climate States of Habitable Exoplanets: the Role of Obliquity and Irradiance
The Astrophysical Journal, 844:147 (13pp), 2017 August 1 https://doi.org/10.3847/1538-4357/aa7a03 © 2017. The American Astronomical Society. All rights reserved. Multiple Climate States of Habitable Exoplanets: The Role of Obliquity and Irradiance C. Kilic1,2,3, C. C. Raible1,2,3, and T. F. Stocker1,2,3,4 1 Climate and Environmental Physics, Physics Institute, University of Bern, Switzerland; [email protected] 2 Centre for Space and Habitability, University of Bern, Switzerland 3 Oeschger Centre for Climate Change Research, University of Bern, Switzerland Received 2017 April 3; revised 2017 May 29; accepted 2017 June 14; published 2017 August 1 Abstract Stable, steady climate states on an Earth-size planet with no continents are determined as a function of the tilt of the planet’s rotation axis (obliquity) and stellar irradiance. Using a general circulation model of the atmosphere coupled to a slab ocean and a thermodynamic sea ice model, two states, the Aquaplanet and the Cryoplanet, are found for high and low stellar irradiance, respectively. In addition, four stable states with seasonally and perennially open water are discovered if comprehensively exploring a parameter space of obliquity from 0° to 90° and stellar irradiance from 70% to 135% of the present-day solar constant. Within 11% of today’s solar irradiance, we find a rich structure of stable states that extends the area of habitability considerably. For the same set of parameters, different stable states result if simulations are initialized from an aquaplanet or a cryoplanet state. This demonstrates the possibility of multiple equilibria, hysteresis, and potentially rapid climate change in response to small changes in the orbital parameters. -

THE POLAR THAW: an Analysis of the Impacts of Climate Change on the Environment and Geopolitics of the Arctic Polar Region

Student (please print name): Alexandra Stoicof Signature: Date: Abstract The issues facing the Arctic region today are of relatively new importance on the agendas of environmentalists, lawyers, and national governments. Global warming is affecting the polar regions at a faster pace than the rest of the world, and is drastically changing the ecosystem and viability of the indigenous groups who depend on the environment of the tundra. The forced adaptation of the natives has lead to convictions of human rights and debates over the accountability of the world to affected communities. The retreat of Arctic sea-ice also exposes another area of controversy; the claims to the resources and passageways that are becoming increasingly accessible. The beginnings of an international race to claim sea territory has lead to interpretations of the law of the sea. -

New Records of Crustose Teloschistaceae (Lichens, Ascomycota) from the Murmansk Region of Russia

Blas- tenia scabrosa is a new combination supported by molecular data. Blastenia scabrosa, Caloplaca fuscorufa and Flavoplaca havaasii are new to Russia. Blastenia scabrosa is also new to the Caucasus Mts and Sweden. Detailed morphological measurements of the Russian specimens of these species are provided. Caloplaca exsecuta, C. grimmiae and C. sorocarpa are new to the Murmansk region. The taxonomic position of C. alcarum is briefly discussed. Key words: Arctic, Rybachy Peninsula, Caloplaca s. lat., Blastenia scabrosa. Introduction Although the Murmansk region is one of the best studied regions of Russia in terms of lichen diversity, there are numerous reports in recent literature of new discoveries there (e.g. Fadeeva et al. 2013; Konoreva 2015; Melechin 2015; Urbanavichus 2015). Several localities in the northwest of the Murmansk region, mainly on the Pechenga Tundra Mountains and the Rybachy Peninsula, were visited in 2013 and 2015. -
Miocene Cladocera from Poland Henri J
www.nature.com/scientificreports OPEN Miocene cladocera from Poland Henri J. Dumont1, Agnieszka Pociecha2*, Edyta Zawisza3, Krystyna Szeroczyńska3, Elżbieta Worobiec4 & Grzegorz Worobiec4 The Bełchatów Lignite Mine of Poland is a treasure-cove for mid-to late Miocene plant and animal fossils, deposited in a slow-fowing river valley with swamps and oxbow lakes. Here, we report the fnding of abundant fossil anomopod cladocerans. Some are three-dimensionally preserved, including the taxonomically important trunk limbs. They pertain to the families Chydoridae and Bosminidae, with species similar to but distinct from modern ones. All are members of the zooplankton, though some are littoral while others are pelagic in nature. Morphological stasis in these families is not outspoken as in the Daphniidae and the stasis hypothesis, based on ephippia only, is challenged. The absence of Daphnia is conspicuous and ascribed to a combination of fsh predation and local water chemistry. Its place in the oxbow lakes is taken by at least two Bosmina species, one of which is undescribed. We consider this a case of paleo-competitive release. For Bosminidae, these are the frst certifed fossils predating the Pleistocene. Te lignite mine at Bełchatów, Central Poland (Fig. 1), has recently yielded abundant Miocene remains of several species of branchiopod microcrustaceans. Tey pertain to the order Anomopoda or water feas, families Chydori- dae and Bosminidae. Te main synapomorphy of the anomopods is the ephippium, a structure in which sexual or resting eggs are deposited and that forms when external conditions deteriorate. Te Daphniidae include the well-known and speciose genus Daphnia, a highly specialized pelagic component of the freshwater zooplankton. -
