Sensitivity of Pliocene ice sheets to orbital forcing

first_imgThe stability of the Earth’s major ice sheets is a critical uncertainty in predictions of future climate and sea level change. One method of investigating the behaviour of the Greenland and the Antarctic ice sheets in a warmer-than-modern climate is to look back at past warm periods of Earth history, for example the Pliocene. This paper presents climate and ice sheet modelling results for the mid-Pliocene warm period (mPWP; 3.3 to 3.0 million years ago), which has been identified as a key interval for understanding warmer-than-modern climates (Jansen et al., 2007). Using boundary conditions supplied by the United States Geological Survey PRISM Group (Pliocene Research, Interpretation and Synoptic Mapping), the Hadley Centre coupled ocean–atmosphere climate model (HadCM3) and the British Antarctic Survey Ice Sheet Model (BASISM), we show large reductions in the Greenland and East Antarctic Ice Sheets (GrIS and EAIS) compared to modern in standard mPWP experiments. We also present the first results illustrating the variability of the ice sheets due to realistic orbital forcing during the mid-Pliocene. While GrIS volumes are lower than modern under even the most extreme (cold) mid-Pliocene orbit (losing at least 35% of its ice mass), the EAIS can both grow and shrink, losing up to 20% or gaining up to 10% of its present-day volume. The changes in ice sheet volume incurred by altering orbital forcing alone means that global sea level can vary by more than 25 m during the mid-Pliocene. However, we have also shown that the response of the ice sheets to mPWP orbital hemispheric forcing can be in anti-phase, whereby the greatest reductions in EAIS volume are concurrent with the smallest reductions of the GrIS. If this anti-phase relationship is in operation throughout the mPWP, then the total eustatic sea level response would be dampened compared to the ice sheet fluctuations that are theoretically possible. This suggests that maximum eustatic sea level rise does not correspond to orbital maxima, but occurs at times where the anti-phasing of Northern and Southern Hemisphere ice sheet retreat is minimised.last_img read more

Gryffindor? They can’t be Sirius…

Exploring the health value of global fisheries

first_imgA new project based at Harvard T.H. Chan School of Public Health aims to quantify the human health value of fisheries around the world, to determine the health risks of fishery decline and collapse, and to develop tools to better manage these risks. The project is supported by a large grant from the Wellcome Trust’s Sustaining Health Program, and was chosen from a pool of 425 applications to be one of 10 selected projects around the world to make a difference in the field of planetary health.The project is led by Christopher Golden, research associate in the Department of Environmental Health and program director of the Wildlife Conservation Society’s Health & Ecosystems: Analysis of Linkages (HEAL) program.Although fisheries around the world are threatened by overfishing, habitat destruction, and climate change, there is very little research on how fishery declines are linked to disability and disease.Using data from a number of existing mega-databases, the new project will quantify the nutritional importance of fisheries for different populations around the world; examine how projected changes in global fish stocks could affect human nutrition; identify populations with the most nutritional vulnerability to changes in fisheries; and develop tools to help decision makers determine the human health impacts of various fishery management strategies.

Student Government announces new chief of staff

first_imgSenior Dan Sehlhorst stepped down from his position as chief of staff at Wednesday night’s student Senate meeting, and it was announced that student government secretary sophomore Sibonay Shewit has replaced Sehlhorst. Siboney Shewit, a sophomore and former student government secretary, has taken over the role of chief of staff from senior Daniel Sehlhorst.Senators had previously been informed of Sehlhorst’s decision to step down, but the announcement was formally made at the meeting. “It’s a result of a combination of personal things and family things that all converged at the same time,” he said. “It came to the point where I realized I would be in a better place, student government would be in a better place and all of you would be in a better place with someone who would probably be less distracted for the next semester, so I decided to change roles.”Sehlhorst said he will remain involved with student government during the semester.“I’ll still be around in an advisory role — I’ll be talking to Bryan [Ricketts, student body president] and Nidia [Ruelas, student body vice president] about my thoughts, strategies, next steps, that sort of thing,” Sehlhorst said. “That sort of management role, though, the kind of stuff that takes more time, will be better served with someone much more talented than myself.”Ricketts nominated Shewit to fill in as chief of staff for the remainder of the 2015-2016 student government administration. “Sib has served as Secretary this year, and proved to be an exemplary team member for Senate, Executive Cabinet and Campus Life Council,” Ricketts read from his nomination letter. “She has taken impeccable notes and promptly distributed them, benefiting both the Student Union and the entire student body by allowing us to function with transparent records.”Shewit also had a major role in launching Onward, the student government moderated online forum created to implement student-suggested initiatives, and in relaunching the student government website.“I am certain Bryan and Nidia will be well served with Sib at their side,” Selhlhorst said in an email.student government did not announce a replacement for Secretary at the meeting.Later in the meeting, sophomore Sullivan Curry was sworn in as the new student Senator for Morrissey Hall. Welsh Family Hall Senator Kathleen Flavin announced that the printing queue has been extended from six to twelve hours, an initiative that had been suggested from Onward.Tags: Chief of Staff, Onward, Student government, student senatelast_img read more

Thumbs Up! Sleep No More’s Elegant Masquerade Ball Dazzled on New Year’s Eve

first_imgWhile Applebee’s in Times Square charged partiers $375 to eat boneless buffalo wings and see the ball drop this New Year’s Eve, downtown revelers donned tuxes and gowns to attend a very different (and oddly, less expensive) kind of glittering ball: The King’s Winter Masquerade at the McKittrick Hotel, home of the interactive off-Broadway spectacle Sleep No More. After the evening’s retelling of Macbeth, bellhops and ballerinas performed in the main ballroom and audience members traded in their creepy Sleep No More masks for more elegant masquerade attire. The labyrinthine performance space offered surprises at every turn, including performances by live jazz and rock bands, ice sculptures, a secret rave room, an old-timey photo booth and no shortage of fully stocked open bars. Decked out in royal robes and shimmering white lights, the king and queen mingled with their subjects, who included Amy Poehler, David Cross, Laura Osnes, Amber Tamblyn and John Mulaney, to name a few. When the clock struck 12, confetti and snow rained down on the crowd, and the ballroom transformed into a full-out dance party. And while we hear the Applebee’s soiree ended promptly at midnight, the Sleep No More crowd was still partying hard at 4:00 AM. From now on, there’s only one ball for us on New Year’s Eve, and it’s the royal ball at the McKittrick. See you next year! View Commentslast_img read more
